I just finished viewing the DVD by Ted Sokolowski on Metal Inlaying. There are tips on there that make it worth the purchase. One point he makes is using a larger particle size powder to let the CA soak all the way through. He demos putting ultra thin CA on -325 mesh powder (the cheap stuff that I had posted about and the same from Douglas and Sturgess) and it forms a hard skin on top and does not soak to the wood. He pulls off the skin just like picking off a scab. He then puts the same ultra thin CA on -100 mesh powder that he sells, and the CA soaks all the way to the wood and makes the powder a hardened mass all the way through. I guess they want the finer powder to be able to mix with resins and cast out smoothly, but it must not work with the CA technique.
Anyone verified that? I did some searching on-line for the -100 mesh powders, and they are crazy expensive by the pound. I did find some cheaper, sold by fireworks suppliers, but it had a very wide range of particle size. Something like 5 to -150. I guess I could sift my own?
