Hi Zafar and good luck with your project. would be real nice to see some pics as you progress. My torch height is a manual setup. It has a rack and pinion with a handwheel on the side. if you look close you can see the silver colour handwheel on the 2nd pic. Works fine can just wind it up and down as the machine is running. Was thinking of automating it but have found that there really is no need for it. Cheers and thanks for looking at my machine.
