Looks really good! Just an FYI, I've seen a lot of these using PC PSU's for some reason. The motors we're using pull .1a at there highest torque rating, so if ever you want to save some space; you can go ahead and use any small 12V power supply you have laying around.

I'm using this small guy, that would be enough to power 15 of those small motors.

This is #2 build. My buddy is the electronics whiz. So when I built this one ,I just copied it wire for wire. ;) Had an old computer under the desk, it was free and I had it sitting here.

The first build had two controllers but then we decided the proximity sensor was the way to go. It stops the second motor from turning when there is a piece of brass sitting there waiting.So now we had the extra controller, so we built the second one.

Why build one ? when you can build two for a little less than twice the price. haha

Nice job. What calibers work on that setup? Would I need a difference pan and feeder for 223 and 308?

I made it specifically for 223 and 308 actually, with no changes required. Both run great with the same feeder/pan. You may need a new pan for much longer calibers though, as they could flip out of the pan. The feeder I believe would work with any caliber, as long as you size it for your largest.

Cheers.

Haha I like the way you think! Proximity sensor is a great idea. I'm an electrical designer, specifically working in Industrial Automation... Give this thing a month or two and it will hopefully be making me coffee while I wait lol.

What exactly did you use for the torch holder? I see in most of the YT videos they have a block of aluminum with machined holes.

I used an angle and cable clamp. It allows me to rotate the flame for proper position on 223/308 but what you're describing to have seen on YouTube is a better option, as it can slide out further to do longer cases (Ex. 300WM).

T.T,

Two things brother;

1) Job Well Done!
2) Considering I paid $650 for my machine - I hate you* :p



*just a little.
 
Very nice!!

Only thing I can think of to improve it might be a pressure reducer or something to keep the flame the same regardless of how much propane you have left.
Might make it easier for consistency from batch to batch.
