AO2: False starts and tube tops

DB Says:

It seems like forever since I made a worthwhile post here. Ahhh, it has been forever.

One of my last dips into the blogstream was this catchily titled start to an AO big-window passenger car for the TranzAlpine.

Things started with a hiss and a roar, but I struggled with the roof. You may recall that I started back then with a piece of balsa, which was carefully carved, sanded and paper-topped. Nice job too, but all very uncleverly to the wrong roof radius so it wasn't a great fit with the end I'd made. Close but no banana.

No worries. Bung some filler on the ends and sand to shape. Erk. OK... try again. Now that looks pretty decent up against the roof curve built into the end... but as the pumped up ends are now a smidge taller, it looks like there's a sag in the roof. Because there's a sag in the roof. That won't do. Throw more filler onto the middle of the roof then. Oooo, ugly. More filler, more sanding, more filler. Oooo, ugly. Rinse and repeat over the course of two weeks. Talk about getting 'bogged' down.

As NZ120 is supposed to be the nice easy scale, surely there has to be an easier way...

Just then, (obviously not "just then", but it adds a sense of drama, no?) I stumbled upon an appropriately sized tube at the hardware store that might just do the trick: let me introduce you to Schedule 80 one inch dia plastic pipe for in-ground lawn sprinklers and the like:
[you may have to hum to yourself while I spend the next half hour dremeling, cutting and sanding]

Now that's more like it!

Darryl, I have no idea how to contact you otherwise, you are the one with RP DX truck sideframes, right ? will they be available for the 'public' ? where can we buy them ? are there plans to build them out of brass or white metal for the public ?
