The cone comes off I was trying to figure if you made the first press without the cone then the cone for the double?Will the cone come off the jack screw? I wonder if that has been changed for some reason? Looks like the wear pattern on the cone matches the adapter. Weird. I'd start by contacting the seller if someone here doesn't solve it for you. If they swapped parts or sold a mismatched tool that is grounds for a return/refund.
I'm thinking that is probably it if the end of the screw has a profile that will fit the adapter with the cone off.The cone comes off I was trying to figure if you made the first press without the cone then the cone for the double?
