Tom, I am the same way. I cruse about the shop in my power wheelchair and I have everything set up that I can run all the equipment from seated in my wheelchair or a quick transfer to another stool chair or even a creeper. I am more fortunate than a lot of people in chairs. I can when necessary actually stand for a short period if I am propped up against something. I can't walk but I can do almost anything in my shop that my normal abilities could do, I just take 3 times as long!. ha ha ha Oh and Yep even the visitors allowed in get to set low rider style.
Yeah I know about that getting older part. all the internal pieces of hardware holding me together is a startin to rust I reckon! I just ain't ready to drink a quart a PB Blaster to remove the rust. Now some of my distant relatives down Kentucky way they make some great corrosion remover called "Old Rip Van Winkle" and I find that is the best for me to keep the hardware moving.
