Thanks to this thread, I bought a new 3d printer, and printed my first one. I decided to go the hex route. The hex heads came in a sack of 4, so I used two. One I epoxied upside down into the plate....the second is mounted to the motor as usual. The heads meet in the middle of the plate pretty much.
That allowed me to both have a handle, and also allowed me to screw the plate down to the motor to keep the plate from tilting. I used a big thick washer between the base and the plate, to allow boolets to drop all the way in......since my plate wasn't quite deep enough. Less friction that way anyway.
I'm experimenting with a special plate for nose down 45 ACP so no ramp or bullet flipping is needed or used. The design required a ring mounted above to prevent boolits from dropping base side down.......IOW's, with the ring just high enough to let boolits slide under sideways, boolits can't tilt base down enough to fall where point down can and do, because of the shape of the plate's holes. The base down unfallen are knocked back to the bottom where they often just fall in nose down or again come up to get knocked back down until they do fall right.
The hole shape also required a modification to the bullet knocker, and a notch in the base, otherwise it would bind up and stop because of the sharp angle of the holes.
It's not finished yet, but here's a little video to show you the concept. Works quite well even in preliminaries.....not perfect, but close, just needs mounted and the top ring adjusted just a little.....
The following picture shows the bullet drop hole shape.....taken during the infill part of the print.....
Thanks, AmmoMike and TylerR for all your generous time and expertise that you have shared. Same with RedlegEd and AR-Bossman.....could not have done this without you.....Just awesome people. When I get it mounted permanently, I will post a working video.....if.....it works as good as I think it will.
Of course I'm posting this not as an expert, but as one hoping the experts will see and pass on any flaws in the plan or suggestions for improvement.
Already looking ahead to the next one........the upsized one thanks to TylerR, for collating .223 and .308. Unfortunately, it will have to use a ramp to flip bullets.
