The turntable is one I built for my own shop, for welding, cutting, & positioning round assemblies. Runs on 12v, with an adjustable speed control, either constant on, or turned on via a thumb switch. We set the turntable next to the welding table and clamp the spoolgun onto the table leg, pointing down onto the part. Part is held up by three right angle magnets. Takes a bit of adjustment to get the part turning true. Then I have a student pull the trigger on the gun, while I hit the turntable button.

I used to do the welds myself by hand, but this is much better. Lets the students take part in the process. We can knock all 8 of them out in 15 minutes. It's fun.
