Mike,
You certainly have a natural ability to see and implement the "foreshortening" of perspective in your carvings That's usually the most challenging part of creating a relief pattern that will carve well and still look like it has the proper perspective/depth. You have that down to a "T"!
Say, I've been thinking about getting a power carver of some type (in addition to my 'standard' Dremels). I've already talked to OldCop (Bernie) a little bit about his particular setup, but am interested in your feedback too.
I know you have several rotary tools, but which tool do you use with the compressor? Is the brand-name "Turbo Carve"? As long as I'm at it, what brand/model compressor do you use? (when it's working, that is!). I do have a 1HP 30 gal. shop compressor (piston/noisy-type), but was thinking about a pan compressor or whatever might be more suitable for an air-driven power carve setup. What are your recommendations, if you don't mind?
