A Forster rep named Scott sent me a picture of their new upgraded shell housing for the CO-AX press.

So going to ask a dumb question as I haven't used my coax yet. What is the difference between old and new?

The pins in the spring channels have been added. I'm hoping that they prevent the springs from flying off (into some as yet unexplored distant universe in your reloading room) when changing the jaws.

Nice but I still think the one from the YouTube guy is better. Search for it on YouTube and check it out. I've had mine for several years and it's still good. The ones from Forster will eventually bend in the middle and arc up. His hasn't yet. I think he claims to use a stronger steel but it's been a while and don't remember the details.

Bending it in the middle of the plate might occur if you let the button head screws that hold it in place get loose. I completely pulled the head off a .223 case in mine once, but my screws were tight and it didn't bend. It looks like the aftermarket plate beefs it up substantially, but keep the screws snug and I doubt you'll have an issue. If it were common for the plate to bend, Forster or Bonanza before them would have beefed it up themselves.

I too find it difficult to believe you will bend that plate unless the screws are very loose. I haven't had an issue with mine and I have also broken off a .308 case head, missed on the lube I think.
I have seen the aftermarket ones on U tube, $35 and Sinclair's site, $69. I haven't heard what Forster wants for theirs yet. I remove mine occasionally to clean and lube under it, not so much to change sizes. So far, I haven't had an issue with containing the springs. As long as one is aware how it works and is, Everyone has a different level so at least there are options now.

I never thought the plate screws were loose but I know if I really tightened them the assembly would bind up. I could move the plate from side to side, but not easily. I don't consider that to being very loose. I would load maybe 8m to 10m a year and replaced the plate about every 4 to 5 years. Other point I like about the youtube product is that the springs are held in by set screws so you can adjust the tension on the springs. I like that. Since I bought a Dillon Square Deal for my 9mm (about 90% of my reloading) I imagine this plate will last longer than I do.
