I have found that as the disease advances, I am faced with some "on" and "off" times. Even during my "on" times I have noticed that as my left hand shakes, I spend more energy with the right hand to help compensate.
Lapidary is very slow work at the various wheels. I am able to achieve the desired shape and smoothness by slowly polishing each stone. The finished product is ample evidence of the pleasure I can derive from this hobby, even with physical limitations.
