Making that Bullet Collator

[dwwright]

I'm printing the parts for Harri678's case collator conversion using a JYG-370 10rpm motor. I'm assembling an entire new bullet feeder for this project. Here are a few pics of the coupler I used for this project.

The coupler I have is 6mm inside diameter on each end, 9mm outside diameter, I used a m3x25 screw for the Tee


Cut the head off the screw.


Used some blue locktite to lock it in place.


Use some blue locktite on the M3x2.5 set screws when attaching to the motor. I did have to drill out motor shaft hole to about 1/2" to avoid the set screws binding on the base plastic.


I had to enlarge the hole on the plate(s) to abut 9.10mm to fit this coupler.


This was a just a quick test of the collator for 9mm, all fed the case head down in a dozen or more tests of it.

I feel like I must be missing this on the thing page, or in the 33 pages I just read.... What spring are you guys using for the flipper?
Eyeballing it it seems to be close to a 3d printer bed spring, but the yellow die springs I have some of laying around seem too strong (they make the feeder jump a lot) even the crappy bed springs that I replaced on my ender3 are too stiff

By the way, don't print your base, and drop it on the ground on the way from the printer to the loading bench... ask me how I know? got a split housing, right at the point where the shell adheres to the bottom chunk. detatched all the way around. I melted it back on there with a hot air gun from my solder/rework station, we'll see how long it lasts, wost case I'll just print another one.

Thanks Mike for all your work and support on this, it's very much appreciated.

I believe I am using a spring from my 3d printer bed, maybe with a coil or so cut off.

I was just about to ask this same question. The spring for the stock anet a8 bed is way too stiff for this. Anyone have suggestions?

Just pulled the Trigger on an Ender 3x with Glass bed........ Can't wait to get started on my bullet feeder.... Will be using it with the Horady LnL AP . I have the hornady bullet feeder die already, hoping to make that work.

Ender 3 is a solid printer, you shouldn’t have an issue. I’m also using a LnL AP, though I started with the hornady die, I switch to the mr bullet feeder after it broke. The hornady die relies on compression to hold the bullets from dropping, which after some use broke on me.

Yea, I have some issues with it and coated bullets.... so this may be the time to switch over

I had the same issue. I was using acme bullets, and the hornady die doesn’t like them. May be the coating or slight irregularities. None the less the mrbulletfeeder die has zero issues.

I have the same question, there is not a single comment on thingiverse or anywhere that indicates the type of spring to use for the flipper. No one can reference a Hillman group spring?

Thanks

Does someone have a collator plate design for 22 caliber rifle? Drop tube? Assorted parts? Also 30 caliber rifle?


I still have my collator sitting in the box unused and untested. I would be interested in purchasing some parts. PM if interested.

I made a thing, if people are looking for an alternative electrical box for the OpenBulletFeeder. This is a more mobile design.https://www.thingiverse.com/thing:3520214

I'm interested in someone selling me the parts. I don't own a printer yet so files are worthless to me.

The 6.5 Creedmoor Drop Tube Big Switch Small Spring has the wrong ID, I fixed the drop tube.

I am just now getting around to finishing my bullet feeder. I have a question. Since the micro switch that is listed on the parts page is no longer being made. What is everyone using now? It's the last stage of my build.

[AR-Bossman]

Double alpha (Mr. Bulletfeeder) will sell you one. I got all the electronics from them and they didn't bat an eye. Multiple times in fact.

I went with the mr bullet feeder switch. Although I'm thinking about modifying the drop tube for it, as it sits somewhat low, not allowing that many bullets to load into the tube.

Others in this chat swear by the light sensor version.
