the vid shows how the machine works pretty good. That was 16G (.060") mild steel.
It took for fawking ever to draw because I had to learn 3 different graphics software packages before I got something that would spit out good toolpaths. Let's say the month of December was devoted to this.
now I could draw it in an hour or two. Its really just a conglomeration of a Celtic alphabet and smaller drawings that BA got for me on a CD, the problem is getting the text and bitmap drawings turned into vector drawings you can make toolpaths from.
you draw and create the design as a raster file. That's what bitmaps and pics are, in layman's terms, drawings made of pixels. You can't machine pixels!
You have to scan it and modify the drawing in different software packages (Corel) and turn all the curves into vectors so you can create toolpaths in sheetCAM. It sure as hell isn't as easy and making a drawing and it just cuts out.
There is a bunch of work in the middle to get everything formatted properly. I'm making these things for BA to sell for her school trip to Scotland in Feb. The kids are selling them, going like hotcakes. I can't wait for it to be over with! lol

hey, I have one question concerning Powermax and the water table. Apparently Hypertherm doesn't recommend using Powermax with water. Have you experienced any problems with the consumables of the nozzle while using the Powermax? DO they burn out quicker? Thanks!
Made a dust sheild for the electronics. If the power bumps, the pc never restarts by itself. I have to pull the covers and blow it all out with air. The plasma and power supply/drive are much more resiliant to the dust, but they should be covered up too.
I've never bought plastic products before - went to Peidmont Plastics across from the Tims on Akerley. Great service, the guy (Todd, iirc) gave me some tech tips and was happy to answer a bunch of questions.
The material cost $80 if you were wondering. I had no idea what it cost either. Its 3/16" acrylic. I asked for the cheapest clear stuff they had - and that is acrylic, not lexan or plexiglass. (Thinner is cheaper, but I needed some thickness so it would stand up on its own)
Peidmont Plastics tossed in some free 'door knobs' if I bought a bit of glue they had on sale. i was just going to holesaw a finger hole, so it was nice to get the acrylic handle for a clean finished look.
Used some 1/4" double channel plastic sliders from a glass supply place to the clear sheets to slide in, and tacked on some 3/4" angle to make a channel to hold it.
Hope that cuts down on the grinding dust getting into the PC. Its slides nice, can be removed easy, looks good, and wasn't too expensive in the big picture. I need to see in there, couldn't use steel.
