Plasma tracing tool

Well got it up and working works good just need to wait fro my foot pedal switch to turn torch on and off , Also going to change the long box arm to aluminum so lighter the the feed rail is fine since is stationary . need to make tracing pen part aluminum since sticks to my work i am tracing since held in place by magnets and the metal pen sticks to the magnetized work.

Looks like you are making good use of those bearings you bought! So it looks like it will trace 1:1 with no scaling, right? Looks like your test circle cutouts came out OK if that's what they are.

yes 1 to 1 . yes circles came out good .

Good implementation. Pantagraphs will multiply any play in the pivots or sway in the arms and affect the quality of the output. There are some implementations of pantagraphs that don't mirror the output - need to change the number of pivots or something like that.

Pantograph i copied worked sorta ok but everything is reversed when cutting and wasn't 1 to 1 . going to order some aluminum box to replace the long steel one so lighter and better balance when all the way to the right and left when traveling . be nice for making my brackets for the cnc table i want to build

Rod do you know why your pantograph didn't cut 1:1? Is it something you can fix relatively easy?

Yeah, you've got a good system there. I can see why you wanted the bearings (LOL) ... AND, you have more bearings to make other things. Ever make that horizontal sliding TIG arm brace? Remember, if you start marketing the sliding TIG arm rest, I get a cut!

I would like to see this in person ... seems like your on to something really sweet ... if you get it worked out you should patent it and market them ... not everyone can afford cnc ... if you can put out something for the average hobbyist I think they would sell well.
