Since my 40 Year old RC-II was, well, just getting old (and I was tired of it banging my shins), I decided to buy a RCBS Summit press. I like the concept and it sure seemed like a solid press.
Then it arrived. When I un-boxed it yes, it was solid. All 22 pounds of it. It was also well built with a great finish on it.
Then for the disappointment. It looked like whoever assembled it did it all by hand without a single tool. The bolts at the pivot points were inserted and the nuts screwed on just far enough to keep them from falling off in transit. Same for the bolts securing the central guide rod to the base and to the upper pivot casting. Looking in the manual for instructions on the loose guide screws on the back was a waste of time. Nothing there. The instructions they did include for adjusting the bolt holding the linkage to the upper pivot was totally bogus. Called for tightening the bolt until the operating handle would stop in any position you left it. Do this and either the bolt would snap or one of the ears on the rigid casting would snap. I ignored.
Then for the Pièce de résistance. The upper pivot was loose on the central support. Not just loose because the screws were loose but loose as in too much clearance (ID of pivot casting to OD of mating surface on Central support). I tightened the screws as tight as I could with a long allen wrench, adjusted the guide screws as I thought they should be, and proceeded to size 50 pieces of Lapua Brass (more on the results later). After sizing these cases the top pivot casting was loose again with the pivot point moving up and down noticeably as I lowered the handle so the die hit the shell holder and when I moved the handle side to side. I shouted my universal word of disappointment, my wife shouted "are you OK" and I retightened the bolts.
I decided that maybe I wasn't doing some secret adjustment so I tried to contact RCBS. Sent them an inquiry. 5 days later, after no response, I sent another, waited another few days and still no response.
I decided to tackle this myself. Removed the top pivot casting and measured the ID/OD of the two mating surfaces. Also used a feeler gauge to see what it would take to take the "slop" out of the assembly. Found I could cram a .004" gauge into the gap so I cut a piece of shim stock .002" thick that I could fit in the circumference of the gap. The .002" shim just wouldn't quite fit so I cut a similar shim of .001" thick stock. Fit snug. I left just enough gap at the ends of the shim so the bolts would fit through.
Reassembled the linkage and checked for any slop, with and without upper mounting bolts loose. No more annoying slop and now the bolts won't be subjected to the stress that apparently were loosening them while sizing.
Sized cases BEFORE the shim was added and bolts were loosening averaged .0015 to .003" TIR. AFTER I finished my shimming and tightening the next Lapua cases (from the same lot) measured .0005" or less, with some not even moving the needle on the gauge.
I really like the press. It definitely needs the long handle to F/L size cases but the short handle is all that's needed for seating or neck sizing only. I bough both as I could forsee this issue. Another nice feature is that the press doesn't want to tip forward as pressure is applied, the primer catcher is a lot better than on the RC's, and lastly-------- No more dings in the knees as I slide under the bench with my chair (or hitting my head on the linkage when sitting back up after picking a piece of dropped brass up from where it landed. ;D
I wonder why RCBS didn't bother to FINISH the press in the factory. Can't blame this on sloppy Chinese workmanship, this press is built in the good ole USA.
