First of all.... which Model Thermwood is it ? Does it have a floppy disk or CD ROM Drive ? If so this part can be programmed and sent to you for input into the machine. If you don't have a drawing and all you have is a sample of the actual part then perhaps the hand held controller is the way to program here. I am have run and programmed for the Turret Model with twin 5 X 5 tables. 91000 control and OS2 system.
