Found enough stuff in junk boxes in the garage to come up this circle cutting guide. Parts list:1/4" all thread1/4" nuts1/4" barrel nuts (had to buy these at Lowes)1/4" x 1.5" fender washers (Lowes has these too)Big speaker magnetRound chromed trim plate for shower head pipeShock absorber mounting stud and nut1/4" thumb screwPlastic collar that fits over a toilet tank overflow pipe that has the ears to mount a flapper valveSquare metal plate from innards of refrigerator icemaker fill valveDrilled and tapped CL of stud to accept thumbscrew. Cross-drilled stud so thumbscrew trap all-thread. Ground stud nut corners to fit inside magnet hole. The pictures tell the rest. It works. I'll add photos when I figure out how to resize them below limit.Last edited by Teddco; 01-30-2007 at 05:56 PM.Reason: Posted bfore photos were uploadedTeddCoHTP Microcut 400 & Invertig 160DC Smith Dual Guard MD-510 OA Rig Lincoln SP135+ Hobart Stickmate LX 235/160
Reply:Sounds great, considering the unit from Miller is about $130. Can't see the pic though! John - fabricator extraordinaire, car nut!- bleeding Miller blue! http://www.weldfabzone.com

Reply:I used a scrap piece of 10ga. with a hole big enough for the tip of the plasma to sit in (3/8") and drilled holes as I needed for the radius and punched the sizes.DewayneDixieland WeldingMM350PLincoln 100Some torchesOther misc. tools
Reply:Looks good. How much total cost on parts? fuzz - sounds like that would work too, I was thinking the same thing, except with round tabs bent down to give stand-off height.John - fabricator extraordinaire, car nut!- bleeding Miller blue! http://www.weldfabzone.com
Reply:Nice. I need to make one of those too. Thanks for the post and pics. I especially like the toilet flap part. A very classy & improvised touch! Hobart 140 Handler w/ gasHyperTherm Powermax 380 Plasmaoxy/acetylene

Reply:Hey MacGyver, I mean Teddco...nice job!!I use the same method as littlefuzz. It comes in handy when making pieces like fan shrouds for custom radiator applications.I like Teddco's deal though....just might have to build one.I'll just tell my wife that she can't use the ice maker, toilet, or shower, half of our surround sound system doesn't work anymore, and the right side of her car may be a little "bouncier" than usual!! - Paulhttp://all-a-cart.comWelding Cart Kits and accessories

Reply:An industrial Suction Cup might make non ferrous materials usable with this application. Either that, or if the material is thin enough, get a matching magnet and make a tasty tasty sandwich with the work piece.I love hacker solutions to expensive problems! Just remember folks, Garage Sale season is starting to get into full swing so parts can be gathered on the cheap.The world is amazing when you are slightly strange.

Reply:Does the part that cups the torch have to be non-metalic? If it is metalic will it short things out?

Reply:Looks great!!!! and a lot cheaper than the mass produced stuff, Threaded rod and couplings, will make it way bigger than the gimme ones, in the PM case deal... may be a lil sloppy but you can make Em big as you want with extensions,That is so smooth circle cutting blows away using a string!!!LOLedit ya the old ones will short,I think most do at least... My PM 30 don't but a lil standoff would give me more power without touching the plate,a lil elect. tape or non conductive bushing and you're good to go I'd bet...

Reply:If the plasma torch uses shielded consumables (another copper piece in front of the nozzle) then the nozzle will not short out......if non shielded then you would get better cut quality and consumable life if the hole that the torch goes through is non conductive.I use my PlasmaCam for holes....works great! I have to admit that it does not work for all applications! In cases where I need portability I use a small magnet with a screw in the center as the pivot, and a piece of wire with a loop in it wrapped around the plasma torch retaining cap!Jim Originally Posted by jdh239Does the part that cups the torch have to be non-metalic?

Reply:@jimcolt, so in this picture of my tip, you are saying to place it in a non-conductive holder then, correct?

Reply:Hmm.... the more I think about it, I don't think it matters as this drag tip is screwed onto an insulated shield. But am I right?

Reply:The picture shows a shielded front end off a Hypertherm torch.....the copper on the shield can touch anything metalic.If that was a non shielded front end....the nozzle (some call it a tip) would be exposed, and for best performance this type of front end should be used in a way that it does not conduct to a circle cutter or to the plate.The shield is isolated electrically from the nozzle, and is designed to shield the nozzle from double arcing to the plate.Jim Colt
