I am currently having my logo art work done. I have almost settled on the final cut. I am thinking of having someone laser cut the logo and the negative in the peghead. I was also wondering about negative engraving on the peghead and filling with some kind of material that starts off as a liquid and hardens (like epoxy.) I want something that I can vary color, content (speckle?) and so on, and then sand down to a flat, flush surface with minimal if no shrinkage.

Ideas?

When I am not using pearl, I have done exactly that.
I have used brass powder, silver powder and other colored powders mixed in epoxy.
Works fine. It also works by packing it in and wicking in thin CA

I use Douglas and Sturgess powders

You say colored powders... where do you get these? And, is there a particular brand of epoxy you prefer?

Thanks Andy,

Mike

The colored powders I have used are Jacquard products.
You have to practice a bit to get a feel for how much powder and how much epoxy.
I have always used West Systems Epoxy. I have a large bottle of the resin and 205 and 206 hardeners
You can also use polyester resins.

They are available in small jar sets. A lot of craft stores have them. If not check the site above and order online

If you're getting stuff laser cut then wood and plastic look good, shell does not. Lasers tend to make a mess of shell.

If you're looking for some interesting textures, and you've got access to a laser, then another option besides pigmenting resins is getting textured plastics like Corian ( http://www.coriansamples.com/prostores/servlet/StoreFront ) or some of the textured acrylics from Acrilex ( http://acrilex.com/index.cfm )

If you're looking for more traditional colored pigments(i.e. no pearl) try:

I've used them several times w/ epoxy; it doesn't seem to affect the hardness or curing time.

In an unrelated topic, they also sell fish glue in the "Binders" section

Check out a product called Inlace. It looks like what you're after. Haven't used it myself, but I do have a friend with a laser, and am contemplating it for future projects.
