David, you have hit the nail right on the head with your second sentence. On a good day I can cut a straight line with the best of them...on a bad day I couldn't even draw a straight line, let alone cut one. My bad hand days seem to be increasing recently, despite the new medication...the weather doesn't help either. Rather than waste several sheets of styrene I asked Andy to do the honours on his cnc machine...the rest you know.
Believe me, I wish with all my heart that I could use my limbs like I could ten years ago, but I cannot...I hate having to ask people for help, and relying on people, but I am lucky that I have some very good friends who will help me out and keep me in the hobby.
