As a project, I’m thinking about building my first piece of rolling stock. One of the things I’d like it to be is short – like, about half the length of a typical car, just big enough to hold a pair of truck assemblies. Since there aren’t to my knowledge any commercially available cars of this length to start with, my first design hurdle would be to create a suitable frame/chassis. Seems like I have a couple of options:
- Use a piece of sheet metal and start from scratch.
- Take an existing chassis from a cheap car, cut out the middle, and then attach the two ends together.
Which approach would folks suggest?
And if the latter, what technique would you use to connect the two halves together? I’m thinking my options are:
- mechanically using a brace piece and small bolts
- an epoxy like JB Weld, or
- soldering/welding
