HyperTherm Powermax 350

Has anyone foun an inexpensive attachnent to cut straight lines or circles that could be attached to the tip?
Reply:Here's a circle cutter that someone made
Reply:I have a similar contraption that I made. I was looking for a kit that could be used to cut straight lines and circles. Mabey a magnetic attachment? How about a drive gear to allow slow accurate movement? You know how hard it is to move the tip slowly by hand when using a straight edge.
Reply:maybe make something that lets the torch ride in buggy on a channel or on rails adjacent to the piece.i'll see if i can draw something up later
Reply:Thats what I was thinking. A "buggy" with a gear drive, and a crank or wheel to turn by hand. Would allow slow and accurate movement during the cut.
Reply:hypertherm makes a circle cutting attachment for that torch, also a magnetic cutting bar works wellKeep your stick on the ice
Reply:Go to the Thermal Dynamics site, they sell a kit for the cutmaster to make circles half moons what have you. Whether the kit fits your torch head is another story.  I took pics of part of the kit today, and posted them on that other board, but only of the wheels that attached to the torch head, I will dig the pics out of my computer and post here.  Might give an idea to some of the guys to make a homemade one.There's a method to the madness, disregard the method and the madness begins!!
Reply:here s the pics, I bought this kit from my supplier, it is made in Australia, about 450.00 canadian, it also comes with a circle attactment, magnet and suction cup.  Can make a circle up to I think 36 inches, not sure.What I did like about the kit it the wheels that mount to the torch head, you can set your hieight, and works very well on thinner sheet metal.  Use it with a straight edge and works very well.I would surmize, that a handy guy could make this at home, so I post for ideas.

Reply:I think you might be able to build something similar to bigrig guys little carrier, but to where one wheel would fit into a small track. That way it would hold proper standoff and you could position yourself anywhere around it and hold it with both hands and get a nice steady movement perfectly straight along your home made track.Lean mean TIG weldin' machineSquarewave 175
Reply:I've got a Spectrum 375. It came with a  roller standoff like the one in "Big rig Guy's" photo. With a good tip the cut is 1.5" from the roller. I clamp a straight edge to my stock and use that as a guide.Pay close attention to keeping the roller up against the guide. The first cut I made looked so good, and I was so proud of myself. That on the second cut I didn't pay enough attention, and made a beautiful scallop on my stock. (.063" 6061 aluminum sheet).When I get some spare time, I'm going to make some other guides based on the factory roller, including a circle cutter.
