On the "you suck" dumpster dive thread I revealed the channel I surfaced with, and intention to build a press, my question is: How much tonnage will be safe?
The frame will be built from 135 x 35 x5mm channel, the tapered variety, I'm looking at using two 28" lengths each for the top of the frame and the moving "table", the top bolted and welded to the uprights, the table sat on 20mm pins through the uprights' flages, a bit like this pic:
(Excuse the appalling Crap-O-CAD)
Close up the Channel looks like this:
So I guess my worry is, with a 25" span between the uprights, is it going to do a good imitation of a rubber crutch the first time I apply a bit of pressure?
Ay help or corrections from those who have built and not broken (or even know how much it took to break!) anything similar much appreciated!
