Open source case feeder - 223R/556Nato or 308W (Dillion 650, Hornady L&L etc) by gzcwnk

*July 2020
As we had 50 people killed in NZ we have lost access to AR15s etc hence no more development on 223R for this. Source code is there for you to modify to your hearts content.
Dec 2018
All parts printed, assembled, Beta testing (part BoM below). Made both 223R and 308W options. Operational test using 5rpm motor, 2rpm motor on order as slower is good enough IMHO.
I found that the Setting angle is 55Deg, but this might need tweaking.
Bench test,https://www.youtube.com/watch?v=bXv3oofM15c&t=44s
Designed to be printed on a 200x200mm 3D printer.
Please note the step and f3d files ie source is provided so if you want a different caliber download and edit the fulcrum and the four outer plates, and drop shute tube as necessary.
The source files are however a bit of a mess, need cleaning up.
a) 1 base plate centre, motor mount designed as changable/replacable.
b) 4 quadrants of base plate. Bolt up but keys probably best to superglue, use a very thin superglue that has capillary action.
c) 1 case collator plate centre, flange mount designed as changable/replacable.
d) 4 quadrants of case collator plate. Note that the prints seem to twist a little so after bolting them up get them even to each other and superglue the keys.
e) 3 sides. plus 2 joining plates and final guide plate.
f) holder/support bracket. I found the distance for my design all wrong for the Dillon dog leg 26mm OD pipe so I fitted a straight 25mm OD pipe about 615mm (cut to length as needed) long. You can get Carbon fibre tubes/pipes in 600mm lengths which would look neat so I might mod to use these later.
g) Control board, this is an optical switch, will add an on/off switch.
Other parts
a) 6mm ID flange to mount collator plate to motor
b) Suitable motor, 2rpm motor is simplest as it needs no controller, hence cheaper and easier and can top up faster then you can!
c) PWM controller but with a 2rpm or 5rpm motor a PWM controller isnt needed to slow it down, just the optical switch.
d) Other parts, to be determined.
e) 25mm OD straight alloy tube, 615mm long (approx, cut to size to suit) replaces the Dillon dog leg tube.
Notes
21-July-2020
A 2rpm motor is my suggestion as it needs no speed control so a lot simpler.
14-June
Now the bullet feeder is in beta testing I am back on this. At present I am sorting out how the case feeder base and case feeder plate sit with one another. Next I will finish the walls then start on the actual collating bit.
24-June
Bullet feeder still being worked on but I am sorting out the base and case collator on this. Moved on to designing the dropper at the moment.
7-July-2018
i) New 223 bullet feeder plates uploaded, being printed at present.
ii) New walls uploaded, yet to be printed.
21-July-2018
Bench test.
Assembling on press for fit.
22-July-2018
Bench test and fit went fine so re-printing in coloured eSun PLA+ for a beta test.
Modified and uploaded a BETA 308Winchester family collator plate. This needs to be printed and tested.
Modified and uploaded a BETA 308Winchester family fulcrum plate. This needs to be printed and tested.
15th October part BoM

Why do I use aliexpress? and not say Amazon or Ebay?
Because I am not in the USA and shipping hurts.
