This in my initial test for fit and function. It went much better than I had expected, nothing broke and function was as intended (albeit a little more vigorous then expected).


I never really cared for the case feed mechanism on the Load Master even though It works and I have no problems getting it to function. I always felt it made operating the press feel heavier than need be.

Realistically, the pneumatics make the operation of the lever feel about 15% lighter.

The valve is a generic 2 position 5 way and I am using my shop/garage spare air compressor with a 1/4 supply line.

The test video was shot @40psi (A little too vagarious), it is now turned down to 20psi.

I may rig up a old fire extinguisher bottle as a air storage cylinder and see how long it will fun on a limited air supply.
 
My thoughts:

1) This is a brilliant idea and seems to be designed well, gets the job done, and is quite creative.

2) After watching the video, I am was laughing extremely hard. It is such an aggressive force pushing each case into the press. I do believe I laughed every time the press hit the switch to release the little devil.

3) I think that concepts like this could be used in multiple aspects in our hobby. Such as pushing 40S&W brass through a G-RX die. I do believe I have seen a video before of a gentleman who designed one, but I also believe one could be designed on a simpler scale? Just thinking out loud.

Either way, kudos to you for a slick design and creating something you needed!
 
iShoot17 and GarySTL,
yes it is a little on the fast side in the video. That's why I ordered a inline speed control valve and reduced the supply line to 20psi. The action is a good deal gentler now.

Made me laugh to on the 1st test! That is the smallest piston made and it is actually rated up to 108psi. At a 100 psi (yes I tried it) you can not even see the damn thing moving! At max pressure it has 15lbs of force at 20psi it's about 2lbs still more than enough to get the job done.

Thanks for the kind words in regards to my design and execution. The process continues with a real production run this weekend. video to follow.
 
When I was using a Loadmaster I did notice that the case feed added the need for additional force on the operating lever. I used a much less innovative method to reduce the required force. Silicone!
Cleaning the case slider helped a lot too!
