You are doing great, I have only ran 6 stocks across mine.

The tricks: Sharp cutters, cut flat only (horizontal), small rotations of the stocks. Rough out at least 0.100" oversize first, then go back and finish carve.

I will start another post in a few minutes with "The Rest Of The Story" on my duplicator photos, it has some tips for success.

Actually it will be two threads:

1. Making a pattern stock

2. Duplicator setup.
