Yes, the locking collar adjusts on that 10 threads per inch (TPI) section. Very nice feature. Gives highly repeatable stop for cracking walnuts.
When the ram is raised for the next sequence, it is very convenient to accurately control how far the ram extracts. For instance, although not shown in these images, I am able to set the upper stop position of the top tool.
The top tool floats on the magnetic chuck, so I need it close to the bottom dies to tweak in the alignment. This is a new application of the mag chuck: I was delighted with how well the top tool tracked on the downstroke. It is all about precise axial alignment, which may be prototyped by hand and eye!
Never mind that the bottom dies skived the test piece:
And here is another tribute to the ubiquitous bed frame angle, as it cut cleanly into the galvanized chain link fence tension wire.
Lacks only a slightly wider gap, a bit of radius and polish, and a bit of punch lube...
WARNING! Metals That Are Hard, Tend To Be Brittle!
Some bed frame angle WILL Shatter.
Always test for Shatterability before subjecting to stress. I know that more than a few of you have shared my experience of having a surgeon spend and hour digging (accident) shrapnel out of the flesh. Also far easier to put an eye out, than to put one back in
