[TheForge] fly press stop nuts

[Steve Smith]

I can't imagine doing damage to a decently designed stop nut. You would 
also do damage to the threads on the flypress, if it is anything like mine.

Bruce, I get a different picture in my head from your description as 
compared to how I use mine. Sure, you're using the screw, up and down, 
but I never turn mine further than about 90 degrees. I always keep a 
hand on the handle. The point (in my view) is that the screw gives you 
excellent mechanical advantage (about 40:1 on mine). The weights on top 
add momentum, still at that same mechanical advantage.

The flypress works extremely well at drawing to a precise thickness (due 
to the stop). Since you can see any ripples left in the surface, it is 
really easy to get a nice smooth result. The top tool travels in a 
dovetail slide, always striking in exactly the same place, plenty of 
precision and power at the same time.
