My family used to be in the construction business. I still have the totally useless to me now hundreds of house plans my father and I drew on drafting paper. Got rid of the drafting tables but I still have the tools: scales, triangles, T-square, pencils and lead, erasers, compass, protractor, french curve, templates, etc. And the skill of mechanical drawing and drafting.
I would help with drawing plans for these gadgets, if there was some way to coordinate the work.
I fear that most of this kind of drawing will have to be reverse engineered.
A pedal-powered METAL working lathe has got to be at the top of the list for machine tools. I know you said wood, but metalworking is very important too.
