Very nice work, and good looking food.
You will enjoy this grinder very much when you complete it.
As a KMG owner, I would suggest 2 very small changes.
1st, the handle for compressing the tracking arm is terrible as it comes from Beaumont.
I suggest you make the arm longer, for better leverage, and easier belt changes.
2nd, I suggest putting the tooling arm locking bolt on the right hand side, rather than the left, as your left hand will be compressing the tension arm, leaving your right hand to tighten the bolt.
I make these suggestions after MANY hours of working with one of these...
I can take a picture of mine if you would like, but I didn't want to clutter your wonderful thread.
