A while back, I got a hydraulic press "kit" at a garage sale. Hydraulic components (pump, hose, pressure head, gauge) all still in their original packaging, unused. All of the steel parts in like-new condition, never unassembled, with two exceptions: no table, and the head cross-piece looked like it had been used for target practice with a BFH.
Built a new head assembly and a table, and put everything together. Looks nice, but I discovered another problem: the holes in the uprights aren't aligned properly. Found this out when my nice flat table wobbled on the pins. Turns out the hole on one side of an upright may be 1/32" or so above or below the corresponding hole on the other side, so at any position I checked, I may need 1/16" or more of shims to get the table to stop wobbling. But while it's now steady, it's not square vs the uprights and may be off by 1/8" in 12" or so in either or both of left-right and front-back vertical.
I don't have a die grinder (no compressor, either), so looks to me like I clean the holes up with a big rat-tail file.
Or is there a better way to fix things?
