Hi Rob,
That sounds to me something like a spin saw or sometimes known as a zip saw, probably some of those other rotary tools like the Dremmel. I have never used one and don't yet own one but I have cut the occasional round hole in duct work using a hacksaw blade in a jig saw and a certain number of bandaides. I have also done it with snips but not very well, not very round and a similar number of bandaides.. For a hole larger than about three inches in diameter something like a stick with a nail through it or a screw through the metal into a stick to spin around that pivot point and use the stick as a guide to keep the jigsaw following works fairly well provided the sheet metal is well enough supported. A proper fine hacksaw blade still wants to make the sheet dance and you will want hearing protection and you should probably have eye protection as well. I must confess I usually forget the eye protection. There are guys on this list who apparently can follow a scribed scratch or line with tools and presumably their fingers but I cannot, or at least not well enough to be any better than free-hand. but if you think you can you should be able to scratch a circle you could feel and maybe follow that with cutters. I expect the spin saw would be the best answer though, what I do know about them is that they spin a cutter something like a router, sort of a cross between a router and a drill I suppose. Maybe when I am back to work and have a income again I'll buy one and see. Anyone else have and/or use a spin saw?

Now I need any ideas on how to cut a 6-inch round hole in a peace of sheet metal.. Y ears ago I worked in a Plumbing and heating place and if I remember right one of the guys used a thing where you drilled a hole in the center of what you wanted to cut the hole and this tool had a pin that you put in the hole and there was a rod type thing and on the other end you could mount a drill this was adjustable so you could move the drill back and fore so you could get the different size hole. Now as far as I know you used just a regular drill bit and just turned on the drill and turned it around and cut out the hole... Now does this sound like it would work or am I thinking of some thing else???
