You gotta love nickel silver. Takes solder beautifully yet parts can be held close to the action without worrying too much about singed fingers.
The chassis starts of easily enough - two sides and lots of spacers to join them up.
When I say lots of spacers, I mean it. There are 6 to contend with here. One even has a nut soldered to it and then goes under another to make a box shaped structure.
The only complication is that to get the loco around tight bends, and I've been asked to get this thing around 4 foot radius curves, the back end of the chassis tapers. I think I've manged to get this equal although the spacer looks like it's in a bit wonky.
The keen eyed will have also spotted that this is a 4-4-2 yet there are only holes for 6 wheels. Hmmm.
