I built this press in 04 or 05, please don't hold me to the year... I got the steel for $240 back then.
The legs are 1" X 5", the 7" channel iron used to build the platens is .318 I think? it's heavy channel anyway.
The side plates at the top and on the sides of the black platen are 3/8 plate.
I cut in half a piece of the same 7" channel iron I used to make the platen to make the feet, you can see how thick the channel is by looking at the feet. it's heavy stuff, I bought the 50ton hydraulic cylinder and pump from a sister company of Carolina Industries. I think I paid around $360 for it.
I still have some things I want to do to it but it' works fine the way it is for what I get into, someday I'll finish it... The biggest job so far was to push out a frozen pulley spindle from it's housing assembly on my Snapper's deck, when she broke loose it sounded like a howizer went off.
After the spindle scare I won't go 10 tons with it without me first building a properly designed cage and put a piece of plate steel between me and the press. For now I use HF quilted furiture mats. The cage is on the to do list also. if and when I get the time.
