The smaller benchtop press was put together on-the-fly so I don't have drawings but, it measures 20" x 40". It weighs about 40-50lbs w/o the bottle jack. The main construction is 1x2", 1/8" wall, construction-grade tube stock. Construction grade material is called A36 which is mild steel -a crude version of 1018. There's a few corner plates and tabs of 1/4" thick, A36 flatstock. The tubes were butted together, welded every few inches and ground flat at the places that need to be flat. -Nothing special at all. I used the Machinist's Handbook to approximate it's capacity and even with a huge margin of error, it should be good for 4 tons -probably more but, few things need that kind of force. I think the bottle jack is a 6 or 8 ton -it was on sale and cheaper than the smaller ones. Here's a couple more photos that show basic construction.
EDIT: The corner welds and welds on the bottom bar are important. Those were2 passes of 1/8", 7018 rod -hot -probably 125 amps. 7018 is the perfect for that kind of strong weld.

Very nice presses!!!! What are the dimensions on the metal you used?
