Asking for my secret casting epoxy is like asking for my secret baked bean recipe, Libby's :biggrin:
I used Castin' Craft easy cast clear casting epoxy from Michael's. You want something with a long working time because the fabric seems to make it cure faster. First I tried the 5 min. stuff and nearly had a "thermal event" in my shop. Also when you pick a cloth for the blank understand that it will turn out a LOT darker than it looks dry. The blank in the picture was made from a deep purple cloth and the light color was white.
Easier to turn than tru stone, started with a Woodchuck, finished with a skew. Did a CA finish. felt too soft and got dirty too fast without it. Had to drill, let cool, and drill again for the tubes to fit. Not sure how much pressure is necessary to clamp with. The first one I used a 5 ton jack, the second I used a vise and didn't squeeze quite as hard and was fine. The third I used slightly less pressure on the grunt scale and we will see how it turns out. I'm thinking if I leave more epoxy in the blank it might have a harder finish before the CA.
As mentioned it is a Atrax ballpoint which just might be the kit by which all other ballpoint kits are judged. IMHO. Got to get back to work now.
