After a break of several months I've finally had my second attempt at a laser cut wood design and this time all the pieces did fit together! There were some gaps that needed filling so it wasn't perfect, but it was close enough. Here's a quick photo of the new chassis for my autonomous vehicle. I'm really pleased with the results and I can see that I'll be doing a lot more work with laser cut wood. It looks much better than my attempts at manual wood-working!
Next steps will be to prime and paint the various parts before gluing everything in place, then I can get started on the electronics, which will be largely the same as last year.
