I have a client that requires LARGE pieces (large for Engine Turning, anyway). And, he likes it DEEP (compare typical guilloche' of .005" MAX engraving depth vs. this client's preference for .014" depth engraving). I decided it that this was the tipping point for aquiring another Rose Engine - a special machine that that could handle the size as well as the forces involved with deep cutting. I found it! That special tool - my new baby! It was last sold at auction about 3

It is very accurate when it comes to engraving. Guilloche engraving has been in use since the 18th century, and it is still in use today.
