I REALLY want to see (from a distance!!) a 'powder' actuated press.

I've built a few and now buy them but, go for it! The biggest thing to keep
in mind it that everything stay square under pressure. How thick is the 4"
channel? How much pressure do you want? You can put a 60 ton cylinder in
there and only use 10 ton of it. Put the biggest cylinder that you can find
in it just for the few times that you really want that much power, most of
the time you'll only use a fraction of it. The down side is the loss of
speed. One of my hyd. presses has 2 cylinders just for that reason. I'm
thinking of my next one being powder actuated... I might be the first kid on
the block! Gunner probably beat me to it.

I have some left over 4" channel from my diesel generator project I
recently completed and was about to begin another project.

I know I can probably buy one "ready-made" cheaper then I can build it,
but since I have most of the metal already on-hand this is the route I'm
taken.

What is the biggest bottle jack that I can use safely with the 4" channel?
6-8-10-12 ton ???

Any suggestions?
