Th primary reason I built this is to speed up the assembly of the HP45 connector. I need to answer that question, did I?

Yes, quite significantly. I timed making the connector by hand and with the feeder. By hand it takes me 5 minutes to place all the pins, and 10 more minutes to place the springs. The springs tend to get tangled in each other.

With the feeder it takes me around 5 minutes. 2 minutes for the pins, and 3 minutes for the springs. The constant tumbling separates the springs. Below some videos of me assembling by hand and with the feeder.

(I really need to lock the focus when I am shooting this. Also, a camera on my hands significantly lowers my dexterity)

There is plenty room for improvement left. The feeder with a vibration motor is really not ideal. Working with an electromagnet is more common, and something I want to try. Also I want a separator. Right now I have either a waterfall of parts, or I am waiting 10 seconds on a part. I also want to easily remove the drum. Right now it is bolted in place, and hard to empty. All of these are food for the future.
