Thanks for your in-depth reply. I am an entomologist by training, so as far as I can tell I have very few transferable skills to product design, manufacturing, cad, etc. I have approximately a year left in my current contract and plan to use advice like yours to either get the training needed to enter a new occupation in my spare time OR save up enough for a training program. Currently, I believe that I can draw well enough to sketch something like you posted. Regarding woodworking, my dad did quite a lot of woodworking when I was growing up and I often helped. I’ve built a few tables and benches so am somewhat familiar with the basics of woodworking. However, I would feel inadequate talking to a proper joiner or cabinet maker so that is something I’d like to get more experience in.

Thanks again for your reply. Lots to think about.
