I built this CNC Oxy/Acetylene torch table to do small runs of brackets.
It has a 30"x30" capacity and uses an un-modified hand torch (Victor Advantage II 250)

This shows the 24v solenoid and air cylinder that pushes the button. I use pin 8 and coolant A on/off to trigger the button in TurboCNC.

This shows the torch cutting parts for itself. This is the "Comb" that holds the work supporting "bed". I posted more info here: page 5 of Sanghera's post
It was (relatively) cheap ($1200, including torch & computer) and fun to build. I am using 187oz 23's, Xylotex drive, TurboCNC, 30v and get 106ipm rapids. It cuts 3/16" @ 49.5ipm. Just another way to skin a cat. Enjoy, MIKE
