I think it’s the pass through shell holder. That’s what I was wanting to play with and was going to machine but wound up using spring steel strapping for my “shell holder” and a linear guide instead of a press.
From the emails I have received about this machine,
An add on accessory for the app like that, allowing folks to size/deprime and sort by primer pocket, just filling a collator, would sell reasonably well.
Guess you can’t see what’s doing the work in that one.
The pass-through shell holder certainly is worthwhile for the boolit swaging boys, and I do love it for primer pocket swaging, but every shellholder passes primers, so unless you cast your own, or swage, I think the feeder makes it....at least for me. I do like the pocket swager, but I'd buy one just to decrimp, since there's no faster way. Great time saver for those who love to wet tumble.
As for your magic size/deprime/sorter.....if you come up with such a thing for the APP, I'd buy one if it doesn't cost twice the price of the APP! I'm sure younger guys on the other end of life would pay more in a heartbeat. Look at all the people who buy Lyman's new progressive venture. More power to them! That ought to encourage you.
Having made 5 collators already....;AmmoMike's little one first.....I decided to dedicate that one for feeding pistol cases to the APP.(no bullet flip ramp required) So I printed up a large pistol case plate today and decided to add the TylerR clutch to it. Sure am having fun with that printer. Took you a year to talk me into it. Ha. I think it added a few more years to my life.
Picture of the plate below.....and below that the clutch parts.....the APP will love it! It'll feed everything from 9mm to 45 just fine....even .357 mag. Already tried that on another collator for the Pro 2000.
Above: On the right is the part that goes under the plate...the 45% angle is repeated on the bottom plate surface to give more frictional area. 6-32 flat head machine screws go through it from the bottom, head is recessed.
On the left is the sleeve that goes on top of the plate, inside the hex columns goes 6-32 nuts. just screw the boles in and they self tighten.
In front is the handle to make it easy to lift the plates. I use nylon nuts on the same two screws. You can tighten the screws from the bottom for more friction. The nylocks don't need to change after the first snug hand tightening. Pretty simple....all credit goes to TylerR.
Update: Parts are put together and installed in the collator.......
Tomorrow, I have to modify the outlet to drop pistol cases cleanly rather than bullets. Should be fun. The collator's a bit dirty....been stored for a while....time to clean it up. Christmas colors no less.
The clutch in the center was designed for the bigger collator's TylerR came up with, but I don't see where it'll matter.
