[QUOTE="Trickymissfit, post: 587047, member: 25383"] I also have a small RCBS Partner press right beside the big press (it really looks small compaired to the other). I use it for a couple little jobs that seem awkward in the Co-Ax. The press was checked with a magnetic cylinder square about six years ago (I used a certified six inch square ) that was about one inch in diameter), and after a very light stoning of the bolster plate turned out to be extremely square when checked on four sides of the cylinder, and the error of the cylinder square computed. Looked to be well under .0008" in the full travel. The reason I had to hit the bolster plate with an India stone was that I found a couple of small bumps that I never noticed before. Looked like the female threads for the sliding jaws was the problem. I wanted to use a small granit cube, but it just wouldn't fit in there. The figures I got pretty much showed up in resized cases and loaded ammo when you figure in errors from the lock ring on the die and the case rim (about .0015" is the norm). I also did a similar test with my K&M arbor press, and it really wasn't as square, but with the Wilson dies being so tight it didn't matter much. gary [/QUOTE]
