Modification of a Forster Co-Ax

[Bat Rastard]

I am contemplating doing a bad thing.

It looks to me that if I remove some or all of the stop on a Co-Ax it would become a cam over press.
The black markered part in the picture shows what I am thinking about removing.
Your thoughts?

If you want to do that, I would suggest that you remove material from the links instead of the cast frame. The links would be more easily replaced than the frame If it dosen’t work out.

It's good that you recognize that, already.

 

[Jager]

So I guess I'd ask... what is the problem you're trying to solve?

 

[danny]

Try it, then let us know how it worked out.

This... and if you decide it doesn't work out then you don't even have to replace the linkages. Just turn them around and you're back to the way it was (minus a few cutouts).

Sounds kinda like adding travel to your trigger. Why?

Not to hijack, but there are a lot of shooters who would shoot better if they didn't have a backstop on the blade. Common misconception, because it FEELS good to our monkey brains, and lines up with our preconceptions of precision, to have a "crisp", "positive" trigger.

Caveat: I'm not talking about BR, because I'm not qualified to discuss that discipline.

Doesnt cam-over induce press flex? No shell holders vs plate. When the jaws grab the rim, what part of press does cam-over occur on? Are you running shell holder conversion?

 

[M60 Tanker]

Maybe I don't understand.
I have the same press, I just run the die down a little extra and obtain a slight cam over.
No modifications to the press needed.

 

[Bat Rastard]

I have decided to do nothing.
I am usually inclined to take a good thing and make it worse.
Y'all have convinced me to leave it alone,
Thanks to all!

probably a good idea/- you can get a little cam over with a coax anyway -- if i need more than that id either modify the die or use a different press. i have had size dies i couldnt get enough sizing out of in a coax

Like said before and it appears your decision has been made, but yes IF modifying anything on a Coax the link arms are the ways to go. They can be replaced with curved ones too if you decide to sacrifice the link arms.

PS I recommend curved or aftermarket arms anyway for better access.

I don't run cam over on any of my presses. 2 Dillons, 1 Lyman, 1RCBS, 1 Harrel's. No known issues with the ammo.. And a K+M arbour press - no chance there!

I tried the curved links, ended up going back to the straight ones. I found the nubs on the curved links contact a location on the casting that wasn't designed to be used for that purpose, I felt it resulted in a sloppy-feeling stop. YMMV of course .

Ok, well....I was hoping to see what would happen if it was done...

Who's curved ones did you get Chris. I run the Inline Fab early edition ones. Well actually I run one on the Left and the straight on the right. I pull with the right hand (easy no jokes ) and load with my left.
Love the extra access and have none of those pointy things that stick out of some.
Forster now makes a set that are very recessed with out those dumb things poking out too .

Sadly the newer Inline Fab ones have those points that protrude out mid arm.

I tried the Forster ones. I agree, the original Inline Fab ones look like they'd work just fine, I should've bought a set when I had the opportunity .

I tried running with a straight link on the right and a curved on the left. I found my shoulder bump was not as consistent as running two straight links. Talking with a fellow shooter who had success with a straight/curve, I think it all depends on the press; it may be fine on one specimen, not so much on another.

I've got two that both have a slight cam over
