Ironworker/punch/brainstorm

Things I need to find and document:

• Proper height for die block: will be when upper arm is parallel with floor
• Angle change over the full necessary throw of punch
• Piranha dovetail- obtain or do without? Is there another way of mounting without a dovetail? how much cheaper to make vs. buy
• buy an entire piranha punching assy? how much does it cost?
• Dovetail specs?
• buy a brake to retrofit dovetail?
• Design "upright" table to go along with it?
