Has anyone sandblasted an etching into wood? More specifically,
I'd like to etch to a depth of 0.0625 (1/16th) of an inch.
I'm working with soft and hardwoods. Particularly Pine, Cedar, Maple, Oak, Birch, Cherry and Mahogany.
I am familiar with the sandblast/stencil process used for etching glass and would like to apply the same to wood. I understand stencil creation/photoemulsion techniques, etc.
I am familiar with the sandblasting concept (compressor, pressure or siphon feed abrasive blaster, blasting medium, cabinet to contain mess).
The only area I'm foggy on is actual blasters. What I've come across are:
Badger mini-blaster
Paasche AEC Air Eraser
Micro-Etch 2 (used for Jewelry sandblasting. I believe the company also makes blasters for dental work).
Glastar Microabrasive blaster
I read somewhere that Campbell-Hausfeld makes a kit that can be used for micro abrasion as well.
There's also a self contained kit (i.e. no external compressor) by Armour sold at hobby stores for $40. It's basically a can of compressed air and silicone carbide. I'm leary of buying this because I don't think the compressed air would move the silicone with enough pressure. It also seems overpriced compared to something like the Paasche and a C-H compressor set up, but IF it works, it could be something used in a pinch when a compressor fails.
Also, a friend told me that the Badger likes to clog up in our humid (Georgia) climate. The Paasche has a moisture trap with the hose. Would that solve the problem if it is a problem? Has anyone used any of these or have experience sandblast etching in wood?
I know I should be a master wood carver or buy a carvewright, but at the moment I'd like to give something like this a try first, if it works.
Any thoughts from experienced users are appreciated.
