STI --- maybe you're using a wee bit too much pressure... you have a little bit of a bell in your photo - which you highlighted with the "box" (nice job btw!)... and that might not be allowing your nut to slip down like it should.. It might be that "last" pump of pressure - maybe try one with a bit less and see what that does for you?
I just went to check mine -- and BINGO!! You found the issue!!! Mine have perfect straight "threads" all the way.... they don't look like yours at all.
BTW -- I use the DUDE thing in there --- just for fun... I don't really talk that way.
Oooh.. Yep, same here. My dies dont have a wrecked thread front like yours. Looks like someone pushed the threads in with the pump.
Now... I wouldnt think you should be able to do that if the dies were hard enough and the user was just flaring tubing. Any tubing, I dont care if its anealed or hard tube. The dies should be just as tough as the rest of the tool. It looks like the dies are soft.
Now you have me thinking. I might just set one up in the rockwell tester to give it a check. Ill bet she comes up on the soft side of what you would expect for a metal forming die. Interesting. JR
Yeah the die seems soft for sure. I just got this die brand new the other week from master cool and did under 15 flares with them. The cone has zero wear on it. I don't think I abused the tool in any way, but something is up for sure.
