How is it possible

[Mike Powell]

Good Morning guys,

I have had a problem for the last couple of weeks. Maybe someone can help me out.

Im not sure how this works, but the rod on my mandrel is unscrewing while I am using it. The reason I dont understand this is the head stock spins the opposite direct from the mandrel threads..

Is there a way to fix this other than TBC?

you could put a drop of ca on the threads to lock it. if you need to remove it later apply some heat, that will release the ca.

The is really odd. The adjustable mandrel with the collet style is the better mandrel to use anyway IMO. That should solve the prob either way.

CA is to brittle for that application IMHO, try some blue Loctite...or which ever one of the two can be "un-locked"

I have the same problem. If you are using the mandrel saver and still have the knurled nut that came with the mandrel, you could put it on the mandrel head side of the rod and lock it down by screwing it back against the mandrel head.

Tail stock not locked down securely or not quite tight enough ???

correct

This answer is correct, I have had this problem myself. When the tail stock loosens the nut backs off.You may have to tighten the nut about a 1/4 turn or so.

Thanks Guys, Ive been meaning to pick up some lock tight.

I tried the knurled nut, but for some reason mine will not thread on correctly. I do use a mandrel saver now, and I thought that was the issue, because it didnt start happening until I started using it. I will give tightening up the saver a bit more.

Thanks for the advise.
