Looks great! How did you cut the slits? Plasma cutter? Milled?

[jason f]

Sawzall with metal blade. Just went slow to keep straight.

Fantastic. Curious how much did it all cost you?

[jason f]

free metal from a friend. 18 bucks for stainless allthread,nuts and washers.

I and others have made it from aluminum and they end up failing over time. Curious why you would go with aluminum over steel?

i wont use aluminum now. thanks for the info that it wont work. i just thought it would be neat to have aluminim instead of steel.

[Utah Shooter]

They just end up bending over time. I guess you could be alright if it were thick enough.

Aluminum is working just fine on mine, but it is rather thick. I'll try to remember to take a measurement. Anyways, looks good Jason f

Jason, if you are going to use alum. use 7075 T6, much stronger than the normal 6061, but steel is still a better bet. and much cheaper. Sprink

:confused:.......I don't get how it works...help me out bro.

The die that you screw in to the top of the press has an ejector on it that ejects whichever component you are swaging. As you lower the handle on the press the top bar on the auto eject pushes the ejection rod down ejecting the component automatically. It sure beats hitting it with a plastic mallet. Here is a picture of one of mine. I don't have a punch installed in the ram. Hope this gives you a better idea.

I get the premise and makes sense to use the leverage of the press rather then a mallet. But how does it attach to the press so it gets pulled down on the down stroke? Looking especially at the rockchucker, my ram is a standard ram do you need a special ram to use it. Just ordered my first swage die, a Ch4d 101 9mm, so this is all new to me.

[IllinoisCoyoteHunter]

There are made to clamp to the ram.

There are made to clamp to the ram.
Do they use a set screw to clamp to the ram?

[IllinoisCoyoteHunter]

No the two bolts (and nuts) on the opposite sides of the ram clamp the base of the auto eject to the ram. There is a narrow "slit" cut out to allow for the bolts to "clamp" the base to the ram. I can get you pictures if you still don't understand. Kinda hard to explain.

Illinoisecoyotehunter if you could give me more pictures that would be awesome. I have access to a laser table and some scrap steal and would love to add one to my press. Thanks in advance.

Please excuse the crooked cut. I originally made it with the 2 set screws but it just wasn't working all that great. Then I cut slots so it could clamp on. I tapped the one side if the base so I didn't have to use a nut. I wanted to keep it low profile and not "bulky" looking.
