The year in review

Well, its that time of the year again when I get to sit down and see where the last 12 months has got me.

12 months ago everything was going into boxes in preparation for the great move north. This has worked out very well for us personally and for me professionally. Its nice to work somewhere where one is appreciated and the atmosphere is rather more fun. The lady of the house has also completed her degree this year (only 20 years in the making) and is on to further study next year. So baring family fires and some health issues its been a good year all round her at Schloss Dandruff

Layout wise tracks were still getting made. I could run a loco a whole 7'.


Moving on 12 months later and short of the turntable and the main join between the 2 northern boards its pretty much done. The major other parts to do are checking the track is all in gauge etc and installing the booster for the DCC set up.

'Oh, and did I say it has to be done for the convention?'

In the loco and rolling stock department, there have been a couple of oddities in the Price Cb and rail truck that saw the light of day. On the real rolling stock front there was pretty much zip. The is no Ew to grace the rails, and the large steam locos remain firmly on the drawing board. With the wagons the main problem I face is decent wheels to an NMRA standard on a short axle. I can't get hold of any of the newer Dapol or Farish stuff (and believe me, I've tried) which have the right wheel size. Any US stuff is just too small (5.5-5.7mm vs 6.2mm and to me yes it does make a difference). The 2mm stuff is very pretty, but my track making skills are not quite up to it. However I'm looking forward to the etched underframes from MMW so that may spur me on in the new year.

So what will the new year bring? I'm hoping for some more etching being done, and possibly even a couple of kits or something. Certainly completion of some of my loco desires for Paekakariki. I'd like to think that by this time next year the layout has moved on a bit more

You'll have to excuse me now. Its raining and I'm off out to the Man-sion....

UPDATE; As an aside, does anyone have any suggestions for a cheapish USB web cam? I'm just experimenting out in the shed and the one I own is complete crap.

Upstairs and downstairs - DG2376

DB says:

I added a roof to the DG today [which is probably a week ago as you read this as I did all this DG stuff over the Christmas weekend] using some 1 inch dia plastic irrigation pipe leftover from the AO cars.

After a lot of dremeling and sanding it's almost done. The real thing has an unusual cross section (curved on top but with steeper sections at the edges, but this will do. Its probably a smidge tall, but so is my other DG. Not shown in the mockup pic below was the removal of a section at the very back of the roof on the port side (avast!) for the dynamic brake roof shutters. I'm sure that will be visible in a later picture.

With that almost sorted it was time to go 'down there' into the netherworld of chassis surgery. The 'new' Kato Pa-1 chassis is DCC friendly, but longer than the old Kato/con-cor ones, so needs a few minor alterations. Luckily, it comes apart very easily:


A little nipping and tucking later and I have reduced the overall length by shaving the ends and removed some of the PA-1 fuel tank as the DGs had tiny tanks:

I then used a marker pen to blacken the lower surfaces of the metal casting that might show under the NZ120 body.

Luckily, the PA-1 bogies are almost perfect for a DG. They are a tiny bit short in bogie wheelbase as almost all N scale mechs are for us (they should stretch further inboard towards the fuel tank), but the details are almost perfect. Technically the PA-1 has a pair of tiny coil springs on the outer of the equalizing beams where we had 1 coil spring, and the top of their bogie main casting has a tiny curve on top of it above the centre wheel, and our brake cylinders are more complex, but none of that bothers me enough to make any changes to the Kato items supplied.

p.s. Except for the bogie mounted sandboxes that one batch of the DGs had (the others had sandboxes hidden behind the headstocks)... I think perhaps all of the late-surviving locos had bogie sandboxes, but just at the '4 corners' of the loco, not one at each corner of each bogie.

Summer

While kiwibonds freezes in a North American winter and has modeling time, here in the south pacific its much harder to justify heading out to the shed for a few hours given its been blue dome weather for the last week or so. Yesterday was gardening and fishing after getting new tires for the car. Hence we get staggered posting about how to build a Dg which I think is now finished, but still has a week to run cos I'm lazy, and if we posted it all in one go then I would have to come up with something else. I have also been rebuilding an old laptop (an Eee 701) adding a new operating system and more memory so that I can use it when away from home.

Fortunately the weather appears to be packing in (slowly. its suppose to be raining now, but like everything else its on a go slow as well), so I'll be able to run away out the back for a while, where many jobs await.

There has also been some discussion in the peanut gallery about entries for convention competitions. Given that its only 3 months away (REALLY) you should all be planning your entries now. I'll do a separate post on reading the rules and whats involved in doing as well as you can.

Gweilo - DG 2376

DB says:

The slang term for a westerner in China is gweilo (bignose). Of course you would never call my nose big if you had met an English Electric DG loco. Aiiiyaaa!

I began by making the front face, which on a DG slopes back a little from the vertical and is graciously curved across the front and suddenly more sharply at the corners. A few plastic corner posts and a .5mm sheet rendered a fair representation of this once sanded down and stuck together.
After letting that set for a while I started on the top section. This is surprisingly tall on the prototype - the top of it comes up to the height of the top edge of the cab side windows. To make this I stuck two pieces of 2mm sheet together and began filing. As with the front face, there is a nice curve all over the top with a tighter radius curve at the corners. To make things even more difficult, the top slopes down slightly toward the front. Again, I think the Trackside kit seems to do a good job of capturing this from the pics I've seen (and again, I should have bought a Trackside nose rather than making my own, but that's stupidity for you).

After a considerable period of dremeling and sanding I attached the nose-top to the body only to find it was too tall. The sanding crew were roused from their slumbers and eventually I was happy enough with the general shape. A little modelling putty was applied in the seams and hopefully some paint, hatches, doors, headlights and handrails will complete the illusion of fidelity.

I highly recommend the April 2002 NZ Model Railway Journal's article on DG locos, which has an excellent range of reference pictures and plans.

Rumble in the Jungle - DG 2376

DB says:

Well I finally made it to my nice clean freshly carpeted train room last weekend, but struggled to find my knife. As such, my NZ120 pilot light was unable to re-ignite any of the half finished efforts that I did find. Somehow I got fired up enough to make some serious progress on a long running Z scale project and kitbash this N scale freak:


No, it's not exactly NZ prototype, but you might be interested to hear that I bought an N scale Kato C30-7 a few months back as I've always wanted one of these UP C36-7s with their lumpy Dash-8 style dynamic brake box. Its not a perfect model, but it will do me. And most importantly, today, when I did find my modeling knife, my modeling juices were already flowing.

Another thing I stumbled on last week was a bunch of DCC friendly PA-1 chassis hiding in my drawers (my desk drawers you understand) and this feeble piece of origami:


Which you may remember from a long-ago post on the use of modern technology in NZ120 modeling

I made this home-made brass etch by starting with a plan in 'negative form' (i.e. black everywhere except where the etch lines should go) printed onto cheap photo paper (because it is coated paper) in a [Dr Evil voice] laser [end Dr Evil voice] printer. Then I turned the printed paper upside down and carefully ironed the DG plan onto some .5mm thick brass strip using an iron (strangely enough).

This process melts the plastic laser toner onto the brass, and annoyingly, while its at it, also has the effect of sticking the paper sheet to the brass. But never fear for once its all cooled down, you can put the whole mess in water and soak off the paper thanks to the photo coatings, leaving the brass nicely coated with black plastic toner except for the grills and windows which will be etched out. This you do in a little tray with some acetone and acid and a turkey baster. Of course I'm not cleverly making this up - you can Google "toner transfer brass etching" if you really want to see how this is done in more detail. It works.

This was a reject sample - note no toner on the top edge of the piece due to poor ironing skills! This could be saved by using a permanent marker to draw over the bits you don't want etched.

Aaaaaaanyway, I thought I might see if I could put some lipstick on this pig as I really should have a model of DG2376; especially now that as I type this blog post, the orientation of the real one is in doubt thanks to the Dec 23 Chch earthquake blitz. I feel for you, Christchurchians...

Since the 'rear end' as I etched and folded it was a bit wide, I cut it out to give me two sides and then made up a plastic replacement back to match my recabbed NZ120 DG 2330. I then managed to glue all of this plus a front headstock together in a geometry that isn't too far off flat and square.

Then it was time to start the nose. Having studied DG noses inside and out for many years I can tell you they are difficult to understand in your head, let alone model, and the published plans can be misleading. The Trackside NZ120 DG seems to have one of the best nose shapes out there from th epics I have seen - the face seems to have the right angles and curvature although the front windscreen face should be sloped more and moved rearward maybe a mm or two which would make the the whole snout look the right length.

Well I'm about to dive in and attempt this with layered-on chunks of plasticard... It might have been smarter to buy a Trackside nose :)

Merry Christmas!

Saturday morning

Well, with the festive season upon us, I have not had much of a chance to do any modeling this week. I've also been expending some energy in getting an old net book up and running. it works, but I'm having problems uploading a new operating system onto it. I'm sure I can sort it out, but its just taking time.

I guess its also the time for an end of year wrap up, so lets get some discussion going. What are your high points and low points (in modeling only please.). Bouquets and brickbats could get a bit too personal.

For me the high point(s) were.
-Getting my track making skills to a point where I can now make good looking track that seems to work well. Being able to demonstrate at shows that its not actually that hard to do.
-Getting back into the show scene, and catching up with friends old and new.
-Making some of the smallest NZ120 locos with some more in the planning stages.

low points were a bit harder and basically boil down to not progressing some projects along as well as I would have liked. Things that spring to mind are the Ew and Ka (both with none). I think this is down to the location of the Man-sion. At Chateau dandruff in Nelson 'Der room' was inside the house, and I could hold conversations with the lady of the house. Now I'm off out in the back blocks and its a bit harder to spend lots of time.

So, we throw the comments section open to the cheap seats. I'll even invite modelers from other scales to post (isn't that generous of me). Just keep it (reasonably) civil.

History is alive and well....

Armless_Fet writes:

I was wandering aimlessly into work the other morning and saw the interior design team were in with all their tools in the lobby by the lifts. Sitting on some trestles was a long plank of varnished wood. Didint really think much more of it, until I left for lunch and was greeted by this:



Gobsmacked I was! As a student of fine locomotive design, I knew that is from Sir Nigel Gresleys A4 locomotive built in the 1930's.



I've always had a soft spot for the A4's....they looked much nicer than the LMS "Coronation" streamliners, and Sir Nigel's influence lasted even after his death....apart from Thompson ballsing about, the Peppercorn A1's are still the best looking 4-6-2 locomotives to come out of the British Isles.

And for those who love all things steam, that sounds like an open invitation for an argument....Begin!

Short update

Just a quick note on where things are up to.

I've added the canvas cover to the rear deck, and added the pickup wires back into the guide holes. After cleaning out the inside of the syringe tube with a piece of broken fret saw blade it has taken it's first stuttering steps last night, which bodes well for the rest of the build once I get the pickup on the rear axles fixed and some more mass into it.

When the hell did THAT happen?

(In which our hero discovers that he has actually become surprisingly competent at some things without noticing).

When we left our last episode the mech was whirring away happily without getting far, and the cab sides were cut out. Another session at the workbench and things moved well along, without many burnt fingers. I should have taken pictures along the way, but as you are all well aware I just don't roll that way. Suficit to say there was some cutting andsoldering and filing interspersed by the sad little plink of yet another fret saw blade giving up the fight.

'Posed next to my double sized ruler'
The cab actually came together surprisingy easily considering its a collection of odd shapes of metal. The plastic deck at the rear was somewhat simpler to do. Personally I was astounded as it is the first time I've tried to do anything like this in brass, and it all came together well without unsoldering itself once (though it did get quite hot at times). As for the atuall prototype, well its a truck of some sort....
I have removed the pickups for the time being as I have to work out where they will go with the lid on.
'looking better'
Next up the obligatory photo with the Cb for scale. I had thought the cab was going to sit too high to clear the front bogie, but it looks OK. The front bogie has now acquired some bush workshop 'wood' frames to cover up the rest of the bogie bits. There are also the beginnings of some weight in the back. There is plenty of space for more weight in the cab (OK, plenty is a relative term) and also under the canvas top. I must go and find out if you are still allowed to buy lead in this country, of if its been banned by the environmentalists.

Final shot today shows the addition of a dumb buffer (on the off chance that it might have enough grunt to actually move something else under its own power).

Not bad for 5 hours of work over 2 days. Not so good for anything important getting done on the layout....

UPDATE; in response to a question, here is a general idea of how I did it. Basically it was sheer dumb luck.
looking from underneath. The top of the hood is shim brass sheet that is curved over and soldered on each side. I've then put a dashboard piece in that provides the bottom of the windscreen.
The top side. Here's where I got lucky, as I just soldered the brass dashboard in and the solder flowed into the right shape. I think its something to do with the silver content. I'd give you a scientific discussion of this but I'm worried about people falling asleep at keyboards, and waking up with a key imprint on your forehead. It does work though, and I just had to do some cleanup on the ends with a file.

Distracted

Well, with all the best intentions I ventured out to the man-sion yesterday afternoon to work on Paekakariki (which has now acquired italics to show its importance). Unfortunately I was distracted.....
'The enormous DCC chip is 19mm long'
I have made a few alterations from previous pictures. The rear underframe has been built up from a couple of bits of 0.4mm PCB. The spoked wheel has been replaced by a plain 7mm one though I might replace it with a smaller 6mm one as it doesn't quite look right at the moment. I was pondering how to arrange the power pickup from the front bogie. There is quite a bit of swivel required for the tight curves and I was not happy with soldering a wire onto the pickup as I had done with the Cb. A moment of clarity gave the solution. I have some bits and pieces of syringe needle as it is a good source of small tube. A short piece of this was soldered to the pickup stub, and then a piece of phosphor bronze wire was slipped into the hole (a loose fit) and the other end soldered to the frame. This set up actually works, and the mech has taken its first stuttering steps on the layout. I still have to sort out how to run pickups off the rear wheels without inducing too much friction.

One thing that the test run demonstrated is that it will need as much weight as I can manage to fit in. Talk amongst the peanut gallery had suggested that plasticard should be the medium of choice for the top. However, having a long history with making small locos work in this scale, I picked brass to get some more weight in. I need to get as much weight as possible forward of the rear wheel for traction.

I sweatted 2 pieces of brass together and then glued a paper plan on as a cutting guide. Fret saw and file were employed for the shaping. I've now realised that I may need to buy a second decent file. Also compered with making track where I might go through a fret saw blade every 2 days or so, I've gone through 5 in an afternoon.

Saturday morning

Well, another weekend has arrived. Fortunately this one is accompanied by inclement weather which means that it will be time to get back out into the shed. Its approximately 100 days to the convention, and things need to start moving along a bit quicker layout wise, so there will be much thrashing of minions (note to self; discover where one gets some minions. Maybe they come as a boxed set at the warehouse?). I will also have to better resist the lures of bush tramways as well (which I am seriously failing at)

As an off thought of this, how many others are planning to go conventioning? Mr Trackgang will be there (I assume) plus the motley collection of odds and sods of bloggers from this site, but how about the rest of you? And have you started on that modeling project for the competitions?

Also, assuming that Paekakariki gets to the ball on time everyone is welcome to bring rolling stock along to run. BUT if you want them to run anywhere except the north and south mainlines their wheel sets will have to fit the NMRA gauge. that means that anything with PECO sets is ruled out from the yards, and locos with tight wheel sets will have a hard job of it in the depot.

So, back to the benches everyone, and lets make a decent showing for our scale.

Plans

So, after doing all the cutting, it was time to see if things were actually going to fit. Instead of photocopying the plans down, I sometimes prefer to draw things out just to see how things work. It can give you a better idea of how its going to work.

I picked a 1930's ford truck as the base. Well, its actually an Opel Blitz but close enough. I've always liked the shape of this truck and it does fit into the period. The closet bit will be fitting the gear drive under the hood, but I can always jack the front end up a bit. I also looked at removing parts of the bogies but these are not as tightly fixed as the previous types that I have worked on. I'll just have to file all the springing detail off instead.

Oh, and it looks like the decoder will fit under the canvas hood. That is a plus at least.

Hopefully at some point we will return the blog to some more normal subjects.

Pointed Comment

DB says: for those of us lacking the ability to craft custom iron roads with a deft wave of the soldering iron, I note that Peco has recently given the snap-track planning department another option with the addition of an N scale three way point. That is all. Carry on.

Grasp on sanity slipping?

Over the years I've provided plenty of evidence that I tend to think out of the box a bit, possibly to the point of thinking out of the next box too. I find it very useful in my chosen profession. Anyhoo, a couple of months back I was looking at another bush loco from a Kato B-train.

This wasn't really sitting quite right in my brain,and like most projects that reach this stage in my brain, it doesn't go much further. Fast forward to last week and while looking at photos from a yahoo group I came across something that did send the old grey cell into a bit of activity (and not just the 'rolling over and going back to sleep' kind). A quick search wound me up at the web page of the bush tramway club, and to one of their pages.

OK, so at first glance there are no real similarities, but as I looked a bit harder something clicked. This then progressed to seeing just how much further the Kato underframe could be disassembled. Adding some bits from the spares box (I think it was a Bachmann 4-8-2 trailing bogie) and trimming a bit more and we get.

I still have to modify the front bogie sideframes to something that looks a bit more bush workshop, and sort out the pickups for the rear wheel. Fortunately the front bogie uses the outside pinpoint style pickups. I did have to swap a 1/2 axle that had a traction tire to get more pickups.

So size wise, how does it compare with the previous benchmark (and those who have seen the Cb in the flesh know what I mean).

'Cor boss, that is small!'

The size for the top is 51mm long, and 22mm high. this should just be enough space for a decoder. I may have to remove the motor clip and glue the motor into position.

Must put more thought into a layout at some point as well. They will look a bit out of place on Paekakariki. I'm leaning tiowards something that will fit into a total dimension of 62" (or 158cm) and 23kg total weight, as this will fit on an AirNZ aircraft.

You're not quite right

Looking at the calender reveals that Easter is the first week in April in 2012. This gives me sod all time to get Paekakariki up and running. Having a bit of a think about what needs to be done, vs what REALLY needs to be done I made a start on the jobs that need to get sorted.

The most important thing is that everything runs well, with no/few rough spots. Thus I've been putting some work in on identifying bad spots that need fixed. This has been a mixture of using rolling stock to identify bad spots and the NMRA track gauge to confirm them. As I wasn't planning to play with the soldering iron till later, I just marked them in red.

The more observant will note that the locations tend to be in the same areas and related to the point frogs. These early points appear to be worse than my later efforts once I had sorted out what I was doing. The check rails seem to be the most common fault. The one on the right seems to be from the really early period where I was trying to get Peco wheelsets through everything and has escaped alteration. The one on the left is too wide and allows the lead Ed bogie to pick the frog. A check with the track gauge shows that these can all be narrowed which should 'fix' the problems. I'll slowly work through the rest of the layout during the week, then have a soldering session to sort everything out.

Getting on with it

Pushing forward with the fuel oil tanks I made a trip to Mitre 10 midweek (power cut at work meant that I couldn't do anything), and came away with a piece of dowel which I guessed was the right size. Getting it home and cutting it into bits of the 'right' length I then plonked it on the layout in roughly the right spot.

From this angle they look a bit big, but the area is slowly coming together

From this angle the size looks about right. More importantly it looks good which is usually enough to get me back into a project.

If only I could find some better photos of the area. I may have to stage a break in to the NZRLS archives.

The research hunt.

How does one catalog all the many bits of modeling research that they have?

Case in point. the other night I was trying to force myself to get started on at least one of the scenes on the layout. I looked at the area round the water tower. and thought that's not a bad place to start. I dug out a reject la casting for one part of it, then thought 'I remember a photo of this area'. But where to look. Unfortunately I don't have a 'photographic memory' (haha) for these things like my brother (He would probably say something like 'oh that's on page 34 of the March 1976 'Railways of Oureggostan' or something similar)

First up I trawled through the photo collection on the computer. No luck. Next I thought 'maybe its in one of my hard cover books.' I also recalled it being a black and white photo and so grabbed the ones that just had black and white pictures. No luck again, though I did spend some time looking at 1950's west coast photos and thinking again of that large layout.

Right, next thought. Maybe its in a Railfan, but again which one. Well, its going to be something about wellington, so its either in the EW article (oh, hang on, there were 2), the one on the Baker valve gear Ka's or one of the ones on banking with the section on out of the capital. back out to the Man-sion .

Hmm, Railfan doesn't have any index on the cover, so I consult the Railfan that I use to keep track of which ones I own and which ones I need to buy to get a complete set. Right, December 1999 and March 200 for the banker articles. No luck. The 958/959 article also yields no photo, and I get to the first Ew one. Finally there it is. Search time 2 hrs (with sidetracking).

Now I know that the more organised would say that you need an index to catalog all o this stuff, but what would I file the picture under? Its got an Ew in it, there's the south end of the loco depot and then the one wee bit of the scene that I want to use. Its really down to the old grey cell at the end of it (who is feeling very put upon).

Oh, and I can't do anything as I don't have any red oxide paint so it was all rather a mute point anyway.

Fill er up.

Pottering in the Man-sion on the weekend I forced myself to make a start on at least doing some more scenic planning. I stuck with the loco depot area and more exactly the fueling points. Paekakariki in the 1960's had 2 separate oil storage tanks and a large coal stage on the south side of the engine shed. This all had to be compressed into a length of 350mm.

I figured out that the easiest thing was to divide the area in 1/2. This makes each 175mm which is about the same length as a Ka or Ja. Its much shorter than the real area, but will still give me the same feel I hope. I was worried that the fuel tanks would look too short (I know the coaling stage does, but I'll have to live with it) but a quick test using 2 30' guards vans as length proxies gave me about the right look. I'll also need to build a compressed air coaling crane and a couple of wagons being unloaded.

The waiting is over

If you remember the last time Mini-Me-Wagon was here here we said "now we wait......"
Well the waiting is over. Pretty good turn around really for this time of year
Here is the etch, brought to you by Mini-Me-Wagons and Two Foot Models
We have some issues still to work out firstly the detail of the hole through the bottom of the W iron made the fold too weak and it bends in the wrong place which makes it damn hard to fold and line up the bearing holes with ease and one of them broke free during folding

The Etch

At the local support group tonight the first folding was finished with a touch of solder on each of the axle boxes and the brake lever we have a rather respectable model.
It was noted by 0-4-4-0T that the detail looks finer than that of the Peco underframes

Folded up - pay attention to the nutter detailed rivets on the W irons

One of the supporters wants to do one with a true to scale axle length of 12.25mm over the pin points (2mm Association standard) which maybe possible


Another shot of the folded underframe

One the early J5 bodies on top has revealed another issue, it looks like the chassis is a bit over length
This maybe the fold lines adding length so another correction and another prototype to go

Under one of the Batch Built J bodies

A very nice model - if a little challenging to fold
Stay tuned for more on this project

Answering some questions.

My discussion on a new way (for me) to make throw bars ahs raised a few questions from the peanut galley. So, with teh aid of some terrible photographt I hope to clear (or muddy) a few things up.
Heres an earlier piece of trackwork from Grassmere. The filed heads of the peco track pins are clearly visible. They are countersunk 1/2 way through the throwbar so one can imagine how much weaker these are than normal.

The top side. the pin (with the chemical blackening layer removed) is soldered to teh inside of the point blade. A notch needs to be filed through the 'foot' of the rail to allow the pin through.
For some odd reason I find it very hard to get these notches lined up on each side. As you can imagine, this does take time. By the time I've stuffed up the throw bar once and buggered around with the notches, it can be 20 minutes to do the lot.

Ehibit B. Just soldering the point blades directly to the throwbar. Easy to line up. 2 minutes if I'm careful. Every bit of metal involved in this assembly has a bit of flex in it, so the weakest link is actually the chemical bonding of the copper layer to the resin PCB.

Meeting up part II

OK, so assuming that this 'meeting did go ahead;
-Admission is everyone brings a model or plate of food?(or both?)
-Would a free for all and chat be OK, or should we do some mini clinics on modeling skills.
-If clinics, what would everyone like to see 9(I can offer track making and guards van construction)
-What sort of dates. is it too close to Christmas, or would the 17th/18th suit (the 9th/10th might be pushing it a bit organisation wise)

So feedback from local readers would be good as well, assuming the local club guys do read the blog. its more for you than the usual suspects.

Saturday morning ramble

Well, I'm on my 3rd cuppa this morning and its time for my brain to have a bit of a wander again for the weekend.

This week a bootleg collection of articles on American modeling wandered unannounced into my inbox. Now, I'm not sure why, but US modeling just leaves me cold and uninspired. An endless parade of SD/GP-XX locos and box cars that all seem to be the same with different colours just bores me to tears. Its even the same with steam locos, which are basically a boiler with all the bits hung on the outside and the rest designed with a T square (the stream liners are a different kettle of fish, and are beautiful). It could just be because I and more interested in older period NZR that I'm more drawn to the British style. Its an open-ish sort of secret that I do have an interest in the GWR in Devon, though in the late 1880's and with a slightly wider gauge than 4'8". Its something that i seriously have to fight to keep in its dark box at the back of my brain. There's also an On30 layout in the same dusty corridor that threatens to get out, and if Eureka miniatures ever does Teddy bear civilians I may well be doomed. I'm not going to mention the New Zealand logging layout that also threatens to get built (and there is another loco in the pipeline for it if I can find the basis for a decent top)

There have also been a few questions on my plans to change the way that I make my point throw bars so I may have to venture out to the shed later today at great personal risk (I should be tidying the house) to take some photos showing what I mean. And I think that I might have come up with another option that could work but will be far more fiddly to do, so will probably die. In my experience (work and home) theory tends to get its ass handed to it in a bag by reality on a very regular basis.

A moment of clarity

I've been pondering getting further on with the Waihao forks layout in the last couple of weeks. I was up to adding the throw bars, and I had even got to the point of drilling out the throw bars (3 holes)and removing the copper clad. However I've always been a bit uneasy about using Peco track pins as it requires a fair bit of countersinking to get into the right place. This makes the throw bar quite weak and i suspect that the whole set up is just a wee bit over engineered. I also need to cut groves into the foot of the rail which for some odd reason are a complete pain to get opposite each other.

While thinking about something else the other day it suddenly hit me that the actual movement I was looking at was 1mm and there would not be that much strain on the joint. Why not just solder the throw bar to the point blades and be done with it? a WTF moment if you will.
so, 1 minute to drill the hole in the middle, 10 seconds to file a bit extra off the copper clad board, and a quick run with the soldering iron later and there we go. The NMRA track gauge even has a thingy to get the point blades the right distance apart.

'The old 3 hole with the new 1 hole (trust me as the photo is a bit crap)'

'2 minutes and we are done'

I assume it will last, and if it doesn't its not hard to replace. It might not work with the heavier code 55 rail, but should be fine with the wiggly code 40.
