Hi Kelly. Mine are thin bakelite with about 1/16 wide letter groove but they do not go through. I turned a very small ball end stylus and have to hold it down when tracing or else it slides off the line and makes scrap. That is why I cut an wider/deeper tracing so I can follow it with a 1/8" ball stylus and it hardly ever misses( except if I have a couple beers before duplicating. This is a poor analog person's HNC-(Human Numerical Control) machine !!!!!!!!!.What is size piece can you duplicate on the Radio Carver??............Cheers, Jim
Thanks Oldrivers, Eric and mike!!!!..Cheers, Jim
