Just a quick job tonight, as I knocked up a chassis for my Z wagon from 2mm plasticard. It was cut to size, and then the holes were drilled for the bolts in the bogies. I then sorted out the various washers and nut's required.
To accommodate the bolts running up into the body (that was full of MDF) I had to drill out some holes carefully without going through the roof. These were about 5mm in diameter. I then just dropped the top on to check I had it right.
It will have to wait a couple of weeks till I can get some angle brass for the underframe.
