Time to change the subject title! Richard asked in response to Del's post: "Thats interesting, can you point me to reading about your action and dynamic lost motion?" I am familiar with the lost motion adjustment of the capstan in a vertcal action, but I suspect your dynamic lost motion is quite something else. I have not heard this term before. Can you describe this? Thanks.
