Thanks for that. Very nice upgrade.
The proper drafts and what would work best for this type of part will be some of the learning curve.
Of that I have no doubt. That will be part of the fun in it.

I have seen quite a few different small hobby and benchtop setups.
I haven't seen any of those that were rated for 20 tons, so one of the issues I may have is too much pressure.
I would probably need to cap the air pressure while still maintaining the ram speed. I have seen those type valves, but have no clue how they work. I bought a big 1/2" pressure regulator for this, but I have already hijacked it to use in my whole shop air system.
The one for this will just have to come a little later. I do have some smaller ones and will use one inline temporarily with quick disconnects.
I was working on machining the plasticizer this evening, but while my collect seemed like it was holding the rod well, it slid some and so I have broken my first threading insert. The first of many I think.
So, tomorrow evening I will install my lathe chuck for the first time and go from there.
