One of the most underrated YouTube channels I've ever seen

McMaster Carr is my go-to for most stuff that I build stuff out of.

[Bipecrazy]

Super glad I found your channel.. The most clear directions and most informative information that I've found. THANK YOU

[JeffinTD]

Absolutely outstanding video! I’d been toying with the idea of doing something like that, for both a Star and a Lee APP. I’ve already 3D printed a nose down bullet collator and I think the combo could really be slick.

Enjoyed all three of your video's. Especially like the design for the star sizer. I'm personal friends with Donnie and Dennis of Bayou Bullets and have tested all of them.

You did a great job on the videos. Looking forward to getting the parts. Thanks for putting the time into this to save the rest of us the trouble. My shoulder prevents me from hand loading as much as I would like. This will be a great help!

[kenkoch]

do you think this could be also set up on a Lee APP press? BTW very well done vid. 100% A+

Hi there, looking at this I see an idea, if you have not tried it already. Instead of the making the clevis for the air cylinder to attached to the lever, why not thread the leaver end to accept the same Himes joint as the cylinder, then bolt them side by side together. Just a thought, but it looks good and works.

You do an excellent job with your videos, very easy to understand, and very easy to watch.


What are you using to feed it with air pressure? As in, how many CFM, what inlet pressure, are you drying or filtering the air?

[matthewmartyniuk]

Have you considered adding an upside down bullet feeder? Thanks for the excellent video!

[jesusisalive]

If you can't make it perfect make it adjustable!

[brngolf]

Have you added a bullet feeder / collator to it?
