I am using the Dayton Motor, at first I had drilled and put a 3/8 roll pin in the shaft and used your stock #2 plate. The diameter of the motor shaft on my motor is 8MM on the dot and the #2 plate is 10.1 (making an assumption based off of the number listed in the manual), because there is a 2mm difference there was some play in the plate when it was positioned on the shaft. I has come occasional issues with jams and I'm not sure if it was due to the plate being loose or what. At one point the plate had jammed and was STUCK, ultimately the roll pin had dug into the side of the plate. I have since abandoned that plate.
I created a new plate with a hex adapter and printed a new plate. When I created the plate I screwed up and did not put the right height for rifle bullets but started testing it anyway while I waited for the new plate to print out. It seemed that with the plate being properly centered and not having the extra play like the pinned shaft did everything worked a little better. Since the plate was very short and the hex adapter was only 1/2-3/5 of the way inside of the plate the first jam stripped out the hole.
Que the 3rd plate - This one I made the proper height so the hex adapter was seated all the way inside the plate. This one worked really well and only had a few bullets go in upside down but did have a few hangups. I did end up having it get stuck pretty good a couple times and at one point the hex adapter started slipping on the shaft. I pulled everything off and found that the set screw may have backed out a bit and ripped itself out of the adapter and galled up the motor shaft pretty good.
It seems these motors are pretty powerful. lol
So, currently I have another plate on the printer, going back to the pinned shaft. This one I made with a 8.1mm hole diameter instead of the 10.1 to make sure the plate is centered with less slop and I can open the hole up bigger with a drill bit if needed. I also included 4 walls to try to help with the roll pin not digging in like the first plate.
