Compound Leverage and Length of Linkage

[Barr]

More force required usually is during full length sizing operation. The weakest link when extracting the case is usually the case head where it meets the shellholder. That casehead brass will usually shear and you have a stuck case in a die.

Think carefully before going ape on the force spectrum. As pointed out above, more force usually indicates a problem or misapplication of a technique.

I've said that several times. I plan to swage bullets with this press(Lee Classic Cast), and I want more mechanical advantage. I've been wanting to do this since I saw the one Swagerman(RIP) had.

I am now on a fixed income, so instead of buying(with non-existent money) a swaging press, I'm going to borrow a shop and make the parts I need. I think it's the machinist/fab tech in me that makes me do these things. I've always loved doing R&D work.

This will be for swaging bullets. I have seven other presses that are used for loading.

If you want to go to the extreme a mechanical lever unit eventually runs out of power. A small benchtop arbor press or baby hydraulic H-frame is the ultimate in power. Queue the extreme modifications required.
