Aaron,

Follow Joey's suggestion. I posted the same question a couple of weeks ago and ended up with the Battery Charger and the Reostat exactly like Joey posted. Works like a charm.

For wire I used automatic welding feed wire. Any welding shop has it and it's cheap.

I got a job to build letters that were about 16ft x 10ft and wondered how I would do it, I got hold of some wire ran it from the roof of the shop down to a table, about 2 ft above the table I attached the plastic insulated handles you use for electric fencing that have springs in, make good tensioners then a cutting wire that went through a hole in our wood table top, which was wound around a stabilo under the hole, and connected to 2 battery chargers, that bit depends on the type of wire you use. We pounced patterns, and then fed 8ft x 3ft blocks that were 15" + thick through it, had problems in the begining with tensioning right or if you pushed too hard you got wavy shapes, but it all worked in the end.

This was a few years back today we use our router to assist instead, we build things in pats and glue them together or shape by hand, doesn't mix well with vinyl [Smile]

Henry, in the photo of the 'One Good Product' is that foam or fiberglass, or what material is that? Looks like it was a fun awesome project to make...

Its foam coated with Styrospray 715 from Industrial polymers in Houston, I think its basically the same stuff as Volatile free, but their stuff is applied through a gun system which is fine if you have a project like this but for more intricate stuff might be hard to get in the gaps and holes. We have a hopper gun for spraying this but find it works best with rollers about 15-20mins open time before it gets hard to move, dries to a hard plastic type finish which we then painted.

I took delivery of a pallet of the Magic smooth and sculp, to see how that would benefit us compared to using Styrospray which is isocyanate based, and not so healthy to use, it draws itself to moisture, so you have to cover your eyes and other openings before use!

So far we haven't had time over to try, but at first look the pallet of epoxy is a much thicker consistency.I'm looking forward to some time over to put it to the test.

We've been looking for alternative ways to make dimensional jobs without using hdu which you can only get in small sizes over here, and at a very high price
