Sarge Posted November 16, 2017 Share Posted November 16, 2017 (edited) case lube same head stamp Edited November 16, 2017 by Sarge Link to comment Share on other sites More sharing options...
PaladinPrecision Posted November 16, 2017 Author Share Posted November 16, 2017 Is that from the cases springing back at a different rate based on brass hardness? I don't actually have the machine yet, it was a friends complaint about why NOT to get one. But if there is a fix to make reasonable ammo or prep I might buy it.

Different head stamps give slightly different oals. Could be a few reasons but it does happen. Lube always helps keep oals in line due to helping keep uniform resistance during the process. Both of the above definitely help when loading manually so unless the PW unit is bad they should help. Link to comment Share on other sites More sharing options...

PaladinPrecision Posted November 17, 2017 Author Share Posted November 17, 2017 SCtaylor- I would say 0.020 inch oal variation is excessive. But that is what an associate of mine said he had with his auto drive. Link to comment Share on other sites More sharing options...
SCTaylor Posted November 17, 2017 Share Posted November 17, 2017 Ah yeah, I'd agree with that too. The linkage appears to follow a consistent path while operating, so I'd assume variations in the up/down stroke would be minimal. I think 2 things will help. 1 as others mentioned, case lube and 2, bullet variations. What bullet & seating die are they using? Link to comment Share on other sites More sharing options...

Here’s some pictures of what I had done to take care of the inconsistencies this takes out any bit of flex whatsoever keep things much more stable and consistent. The original set up have a little bit of flex with the Dillon knuckle where the handle mounted to. Now there’s absolutely no movement whatsoever.

I was just thinking of making a tension rod the other day when I watched flex in that assembly on a youtube video. What would you charge me for you to make another set of those? lol Not sure my little mill will machine steel blocks that well lol. Link to comment Share on other sites More sharing options...
PaladinPrecision Posted November 18, 2017 Author Share Posted November 18, 2017 Machine wise, with the rotary travel and rodends. The machine has hard stops when operated by hand, which would increase consistency. I was thinking about upgrading the rodends to NHBB and seeing if that improved things. But TMZ has a great idea about making the platform more rigid. Link to comment Share on other sites More sharing options...

I would like to take credit for this but actually my buddy “Bill” made me a set of these when we noticed flex in both of our machines. We both have this set up on 650s and noticed some inconsistencies, after a little brainstorming together he’s a machinist, he came up with this. The one other thing that was done that you can’t see is the upper pin was removed and each end of the shoulders were machined back some. This modification now let you snug the upper pin bolts which caused the arms to press against the press and makes it that much more ridgid. I have since moved in a different direction and sold the 650 and after this upcoming holiday will be listing this drive unit with this modification in the classifieds. I would like to be able to say he could make this for others but with his busy schedule at work it’s difficult enough to get little things done like this just for himself and for me to when I bug him enough lol Link to comment Share on other sites More sharing options...
