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?

I've been looking at some designs for my shop press and come to a couple
different styles. I'm not sure which is the better design.

Since my scrap pile is small, I would like to build the A-Frame style,
instead of the H-frame style. Does anybody have any comments on either
style?

I'm looking at a 20 ton press, I have some 4" channel, not sure on the
thickness, perhaps .25", On the A-frame style (Harbourfreight), there
is some strapping, again I cant figure out what thickness they are using,
that attaches the upper mount for the bottle jack to the side frames,
(think cap A). Any recommendation as what thickness of strapping to use?
..25"? When bolting this press together, .5" grade 8 bolts?

What is the shear rating of .5 grade 8 bolts?


Many thanks.
