[TheForge] Press vs Power hammer

[Mark A. Pesetsky]

So here's a good question...when looking for a press, we know we need speed,
both (I assume) unladen and under load. Someone said 2" per minute, I think.
But how much pressure? 10-ton? 20, 50, 100? Is more better?

Thanks,

I think 20 is bare minimum???
