I have an Aloris type QCTP on my lathe, and always had this issue that at times when I release the nut to change position the internal barrel gets attached to the nut and gets unscrewed as well:
at first I didn't make much of it and just let it go, but this thing is starting to get old. I tried adding a washer between the barrel and the nut:
But unfortunately this did not resolve the issue.
I am not sure of the maker of my TP as I got it with my previous lathe. all my tool holders are PhaseII but the TP itself isn't marked. I am guessing it is a phase II, but am not 100% positive.
I notice on the top of the barrel 2 rounded slots that look like there should be some keyed wrench to tighten this barrel to the tool post (better?) but I do not have any such key.
I suppose I should make one if this is the solution, but was wondering if anyone ever experienced anything like this and/or have any other ideas how to keep this from unscrewing every so often?
Another thing that I seem to be experiencing is the stud itself is threaded on both ends, one end goes into the T-nut, while the other goes into the top lock nut. Often when I try to release the lock nut, what ends up happening is that the stud is being released from the lower end T-nut and the lock net stays in place. this might be related to the fact that the top lock nut gets "attached" to the TP barrel, and this also makes releasing the TP to change angle quite difficult...
and this thing is supposed to be a "quick change"...UGH...
any thoughts/ideas/help is greatly appreciated. not a shot stopper but it's getting frustrated
:whiteflag:
Thanks in advance
