HI chaps, I've got a problem with a Bailey plane. It has a knurled knob you turn to move the blade in and out so setting the depth of cut. This knob runs on a threaded bar about 1.5 inches long, like a bolt only with no head. That bar is screwed into a threaded recess in the back of the frog.
My problem is that when I turn the knob to adjust the depth of cut, the bar turns with it so it comes out of the hole it's screwed into. This only happens in one direction of course, the direction where you are unscrewing the bar. The other way is ok 'cos you are tightening the bar anyway. I've checked that the knurled nut is free to turn on the bar. Unfortunately the hole is only a few threads deep, and there is no obvious way of locking the bar or of getting hold of it to really tighten it. Also no way of holding it still while you turn the knurled knob.
I seriously doubt that putting Loctite on the threads that go into the frog would be enough to hold it. Gorilla glue?
As if that wasn't bad enough, the darn thing is reverse-thread too, confusing me further.
Any ideas please?
Regards from Terry.
Sorry pic upside down & I don't know how to turn it round. :
