ML10 tailstock

Never have had a ML10, but insulting you by stating what may be painfully obvious, you do know that there is a key in the Tailstock body to prevent rotation of the barrel?

Recently, working on the Tailstock for a ML2 with a rotating barrel, having removed the Barrel, it would only enter from the back end, with the key removed. Once in situ, the barrel was rotated to bring the Keyway in line with the tapping for the key. This key took the form of a 1/4 BSF grubscrew, with the end filed (insufficiently) to form a key to enter into the key way. Filing and a bit of trial and error found the maximum engagement short of preventing the barrel from entering fully.

Howards reply is the most likely cause. The key has to be twisted in line with the slot in the barrel.

I can't see freezing the barrel will make the slightest difference. Robert Butler

Can't imagine Myford bothering with this during assembly of a new machine where fits would be tighter. Robert Butler

Unlikely, the difference will be tiny. Also, if it did work the quill would jam at normal temperatures, not good.

Something else is wrong, and it's probably simple. Can you post a few photos?

I suggest you measure the diameter somewhere near each end, and compare

My hunch is that the taper reducer has been forced-in, and has swelled the quill.

I sold my Speed 10 3+ years ago, but from what I remember I'd reckon Alan Donovan's reply is nearest. If you got the quill out it's hard to imagine that anything could've been done since with sufficient force to swell the quill and jam it.

I should think if you'd done that you'd know about it!

I'd use a phosphor bronze wire brush too with Young's 303, followed by flanelette patches to clean and a wipe with an oily rag...

Was the taper sleeve stuck by rust, or excessive insertion force?

Measurements would be interesting, if you have them.

Thanks, Dave

Those should be of interest to any future visitor, with similar problems.
