I have access to a small shop with a manual lathe and mill. I also have access to both plexiglass and aluminum stock to work with. I can't weld anything though I do have a soldering iron and/or a small butane torch at home to braze with (not so good at it though). Maybe if you can run the design past me, I could come up with something to work with. As for accuracy, I'm working with wire sizes ranging from 16 to 24 gauge, and toroids ranging in size from 2" OD to 6" OD floral rings :-).
