Hi all, for about the last 25 years [off and on] I have been casting aluminum, brass and copper. Started out using charcoal to melt aluminum, have made a metal cutting lathe, works very well, [did not have the money to buy one], since then I started using and have made two other furnaces, one using LP gas and the other using 240v electric elements. I would like to know if someone knows of a way to control the heat, [without going to alot of expense], with digital electronics, heat range from 1200 degrees F to 2500 degrees F ? I can build it if someone has a readable schematic with all the values and parts list, although this might be to much to ask for, thought I
would ask, thanks Jeff. I cast these parts to build my CNC plasma cutting machine.
