  • Anyone try making a Pantograph Plasma Cutter

    Been toying with the idea of making Pantograph Plasma Cutter and was wondering if anyone has tried with any success so far.

    Found this pic on the internet and the concept looks pretty good althou it would take so modification to apply it to a plasma cutter



    Any thoughts ?

    Not for use with a plasma unit, but I made one that uses an oxy-acetylene torch. The steel pattern is mounted above the torch and is traced by a magnetic rotary follower that runs around the pattern edge. It's the same design as the old Heath shape cutter.

    At my age, I can get the same effect if I stand up too quick!

      Got any pictures?

        I didn't make this, but I did change it from oxy-acet to plasma. D.C. variable speed controll with a magnetic shaft on the motor that follows the pattern .

          Did you pick that up at the auction on 28th Ave

            Oh Man, I missed yet another auction .
            No Joe, it's been kicking around the shop for 4-5 years and gets used a couple of times a year. I still have the torch from it and it takes the Victor Journeyman size tips iirc.
            28th ave. in what city?

                The problem with using a template or magic eye oxy-acetylene profile for plasma is that very few of them,especially the older ones are capable of producing the cutting speeds plasma needs.
                The main problem I see with a pantograph machine is the same.Will you be able to move the stylus fast enough to keep the plasma cutting and how smooth would the movement be?

                    Esab still sells bug-eye burners and they can be used with plasma or oxy-fuel. No problems.

                    Bad thing about bug eye burners are the heads are actually pretty fragile and they can be up to 3k to fix if the sensor gets out of whack.

                    There is a local company that makes custom Jeep parts. They have a Heath type set up that cuts parts out all day. No where as efficient as a CNC but heck of a lot cheaper.

                      Here is the place to go for that kind of thing.

                        .
                        That`s because they are selling modern m/c`s with uprated drives and controls with plasma in mind.The older ones were not designed to be plasma compatible and therefore have much slower feedrates.
                        I have one here that I was contemplating uprating but bought a cnc plasma instead.

                          Woah thats an amazeing cutting picture...

                          What exactly is this magnetic head/magic eye stuff? Can I get a link explaining its operation? Id google it but those searchwords tend to bring up other results.

                            Being a direct 1:1 ratio would it need to be any faster then just cutting it out by hand? I was thinking I could move the air button over to the stylus and just follow the pattern by hand

                            I'm just looking to build a 1' x 2' sized machine to cut out patterns of up to .325" plate. Doesn't need to be any more accurate then .025". Most of the patterns have no straight lines in their geometry

                            Still a lot cheaper then contour cutting with end mills

                              Do you recall where the photo came from?

                              That is extremely interesting. Would love to see more about it.

                              Thanks,
                              David
