The HF 12 ton seems a bit wobbly. Has anyone tried welding the top cross member to the uprights to stregthen it?

It would probly work a whole lot better if you did. do both the top and bottom.

The 20 ton presses come welded up, but in doing so they distort the frame. Mine twists at least an inch when you first apply pressure because of it. Still wobbles too.

i've read that before. you can shim the sides to tighten it up a bit.
i built my own with bearings to resolve that.

I put a square on one side, then check the other and it was out a good 1/4", just using a framing square. I think I'll have to shorten the bottom support to get both verticals square with the top beam.
It sure is a purdy orange, hate to mess it up with welding.

I went one step ahead of that. I built a new press out of 4in. channel, tack welded it ,double checked for square,welded solid. It don't flex at all. Pressed apart my Romy build like it was made of putty. It cost about $70, $50 of that was for one 20ft peice of steel channel.

I have a 6 ton Harbor Freight. It worked OK for building my Romy, AMD65 and Bulgy AK74 but when I riveted the receivers on the Yugos, I sprung the top cross member. This weekend I made 4 straps that I am going to have welded on it this week. It will look like a combination of an "A" frame and an H press together when done but should be very strong.

I really like that roller bearing idea...looks like it would work really well

got the press welded up. It ain't pretty, but I think it will hold. One side had a huge gap between the uprights and the top beam. I split the difference, ran a bead down both sides of the gap then one across the top of both to connect it.
After getting the legs square with the top the bottom cross member does not fit. I'm either going to have to shorten it or move the angle iron legs to the outside.
Used it to push out a bbl. last night. Worked good, no twisting at all. Thought I'd give it a work out with a bbl. pin, but this one came out easy with a small hammer and punch.

flopshot, i just bought one of the 20 ton pesses from HF a couple of weeks ago, caught it on sell for 179.00 also the blast cabinet for 94.00. I love the idea with the bearings, i had been trying to figure out how i was going to shim it up like some of these guys are talking about. also what do yall think about raising the press off the floor some to get it to a more comfortable working height? i see your from NC, i have a son at Ft. Bragg, me and the wife will be up there in Jan for about a month, the daughter-in-law is expecting our first grandbaby.
