Building my own Swaging Press

Jump to latest Follow Reply
Here are my observations.

Ive identified 2 presses 1. RCBS Rebel press 2. RCBS RC 2 , Supreme
  • one of the things we must make peace with is the fact that the knuckle ratio has to be altered, as in the distance between the pivots have to be moved closer so as to make it more accessible.
  • secondly the "Zerk Fitting" on the rebel press can be used to certain extent without extensive machining to the Rebel press. making the ejector pin viable
  • Rebel press will need a machined ram for the specific application.

Supreme press has the primer seating arm that can work with ejection flawlessly, but it too needs the custom knuckle and pair of steel links to make it strong enough. If the idea is to control the costs, then a threshold has to be set so that budget X doesn't fly close to the price of commercially available press systems. And budget X has to be used as a benchmark. This shall also include the cost of the die and punch system. 1-1/4"-12 adapters give us more space to work with as compared to 7/8"-14 setup.

Or a design decision has to be made to offer a solution that keeps the press bone stock, but has the functionality as desired. with an exception to add the slotted Ram to the Rebel press.

As much as it pains me to say it, because I already have a Rock Chucker, my vote would be for the Rebel press. For the following reasons:
- Bit more stout
- More working area
- The ram is going to have to be machined either way. The ejector pin really needs two hard stops, one in housing and one in the ram. The one in the housing is used for ejection and the one in the ram is to hold the pin in place while forming. I don't see anyway of getting the latter without machining the ram. The Rock Chucker is maybe a slightly faster modification but its pretty negligible.

Side note about altering the knuckle ratio. For me that has less to do about making the it more accessible and more to do with significantly more leverage/pressure without increasing the strain on the frame of the press. Essentially you are trading more pressure for less range of motion.

So there is no doubt that 2 pieces of equipment need to be standardized. I wont go in much depth about the specifics now. But I think we have a common ground to begin with. what say @csdilligaf ?

I'm back from vacation now and have been working with Ken and Coxworkshop on parts that will convert the Rebel press to a DIY swage press. If someone can make the parts themselves prints will open source. Or have someone make them for you and buy the dies you want that will fit it. I've bought three of the Rebel press on Ebay now for $219 with free shipping. Yes I am a hoarder! Just keep your eyes out.

Quick video update for where we are at. I've been told to warn you by my teenage daughter that this is the most boring video ever made. You've been warned.

In the future I hope to put together a more complete build video. I'll make sure to get that one teenager approved before I upload it though :cautious:

Its sums up really well.

Yeah that's awesome! Your pivot hole relocation makes much more easy. Maybe you, me or some machinist will be willing to make the parts for people without the equipment to do it if people send in the parts. And people who can do it will have access to the files and prints. When we get some GMI dies we can try them out and shoot some. If the thread is the same as Corbin dies the only thing would be to get the extractor pin height just right?

Yes, exactly. Hopefully that will just be a matter of using some spacers in the bore if the extractor pin is too short. If it’s too long…umm ya I don’t know. Maybe a threaded spacer for the top of the ram?

Made with the appropriate size and strength of threads, this pin can be made adjustable by making it in two pieces. The large shouldered part internally threaded, and the pin shank threaded. And a set screw on the side of the shouldered part.

As long as we are using a custom die set that absolutely works. I'm hoping to make this work with standard corbin, GMI etc die sets. Typically they come with their own extractor pins don't they? Seems like they would have to. the tolerances between the die and the pin are very tight.

Yes, the Corbin does come with a pin. To use Corbin dies you'd have to establish the same RCBS ram resting height and zerk pin location as the Corbin press uses, which looks like that is 1.625" and/or keep that relationship relative to the dies and the throw/working fulcrum of the Crusher type press.
