    started a topic plasma cutter tracer (new)

    plasma cutter tracer (new)

    ATTENTION! ALL METAL ARTISTS AND FABRICATORS!!! i have designed and built a prototype plasma cutter tracer for artists and fabricators alike, using only a cheap berlan from ebay and pt31 torch,

    and would like any feedback as i may put it into prodution or just sell the plans in the near future. thanks for looking, hope to hear some of your thoughts. Here are some of the items i have cut with it. These are not cut with a cnc machine,or have any motoriside parts or any elastictrickery apart from the torch itself. they are all on a4 paper, but the machine table has a work area of 800mm X 800mm. cheers Dave

    nice! what sort or finish are you getting with yours? you can add a drawing pantograph if you need to resize i suppose!?

    A quick Google Patent Search of "plasma cutter pattern tracer" has 585 hits...

    It's a tough world, especially today doing R&D and getting a new product to market.. The patent game has become more like the patent Mafia...

    indeed it is! i have had a quick search about a month ago, but as you say there is a lot to search through. i will spend a bit more time soon going through them all, because i really believe in my idea, and simplest ideas are always the be,st (i hope)

    looks very good dude!

    mine you can use free hand (ideal for artists with a vision, because you dont need goggles as you can't actually see the the cut as you draw) or use straight from a picture (no cutting out needed) or as you do pre cut a template.

    as ive pointed out, it has no electrical parts apart from the torch itself, so no optical tracers or anything using computers apart from me printing an image from the interweb. the only thing similar to it is the 'torchemate' and 'rotten leonard' in that it uses the age old swinging arm around a fixed turret, but thats where the similarity ends. hope this helps!

    I've started doing pretty much the same thing..

    I have a dark room enlarger I bought many years ago and has seen seldom use.. I find images I like, scale them to the 2 3/4" x 2 3/4" enlarger negative size, print the image on transparency film (normally used for presentations) with my laser printer. I use that as the negative in the enlarger and project the image onto the steel plate the size I want.

    I found on a metal artists forum that aluminum or gold color sharpie pens are commonly used to trace the patterns onto the steel plate.. Just follow the image from the enlarger with the sharpie pen then cut it out..

    Could not believe how good the first one a "man in the moon" turned out...

    correct! you cannot comment on my design, but the design is not important at this stage only the results of what it can achieve with the information given.

    no scam, just interested to hear other peoples thoughts on it outside my family and friends. i had an idea, "my ideas are usually rubbish" but they seemed to like this one.
