Chuck,
That is a great space you have going there! I wish I knew more about adapting tools / machines for those in wheel chairs. A late friend of mine was in a chair, and he did some of the most amazing projects mostly with hand tools, and this really nice workbench he built a long time ago... He outfitted his Ford Aerostar van as a wheelchair / camper and did as much travelling it in as he could. He kind of sparked an interest in various access issues since then.
I would love to see how you get everything finally set up. Solving the issues that life and our hobby presents us is one of the biggest parts of the joy of woodworking to me. But then again, I love solving all sorts of puzzles...
Trying to follow the example of the master...
