This is probably the simplest post that I have made here, but the ratio of utility to effort is very high.
The video says it all.

Thanks Tony,
Manys the time I have looked at or touched that quill lock to make sure it was not snugging up. I never dreamed of such an easy fix.
Of all the features making knee mills what they are; their quill lock might be the worst. It's conveniently placed but infrequently used. All kinds of aftermarket solutions have popped up; springs, magnets, counter-weights, none stayed on market long.
It's good its found a way into the forum.
Reversing the assembly is less common now, but an old practice.
Probably due turnover of less committed machinists, with fewer experienced mentors.
Very clever Tony
Neat! And it didn't cost a dime.
I didn't know that commercial solutions existed.Quote:

When I posted those goofy remedies, even googling them, pulled up zero. One was called "Quill Cock"; a molded plastic counterweight in red - profile of a rooster. To not appear in X hundred-thousand returns about insignificant as can be.
They'd been better off, compelled to front mounting; use a left hand thread for CCW operation and some kind of adjustment so it would lock without interference from casting.
Both good points. A LH thread would have cost the factory nothing. An adjustment system might have added a penny or two, but at least they could have provided say 4 to 6 positions for the handle.Quote:

this is a good idea for some, buit for me outa sight outa mind....I would still leave it tight. I just added a nice stiff spring inbetween so they were held apart. witch pretty much keep the arm up when you unlock it. and down is locked. I did that years ago....but i still check every time I use the machine.old habbets seem to be hard to break. my quill has some good marks on it from somebody not paying attn.... before I got the refurbusshed machine... I dont know who/what company refer bushed it, but i think they just had a joint in 1 hand and a spray can in the other hand....smoking their referbush and spray painting the mill. you cant fix stupid, ugly can be fixed, stupid ..not!!! good thing I didnt pay a lot for it...( it's fine, but not reworked like it should of been,or that I was led to be leave)Quote:

Think I will make one of those clamps, seems to me I have heard them called a Cotter ? Then again I may be thinking of something else, but anyway, will make a new one for my mill and use a left hand thread in the barrel and on the stem, that way I can leave the lock lever at the front.
