Do I wash(er) or not?

[Kyle Iwamoto]

its not advisable to use the spindle lock to unscrew a stuck chuck. The pins that lock the spindle are not sturdy enough on most lathes, and don't ask how I learned that expensive lesson!

My Jet 1642 does not have flats, I have to use the spindle lock.

Kyle, my 1642 also has no flats on insert or spindle either, I very gently used spindle lock today also

I wonder if there is some way to put it in reverse ??????? without spinning it off the spindle

Good trick Aric, thanks

Do it the right way---buy a 4$ can of antiseizing compound at a auto parts store. Eliminates jammed threads and misalignment due to washers. Also it lubes the threads which may be used for many years. Most machinist use it faithfully. A dab 2-3 times a year does the trick. Also a properly tightened work piece should not back off when in reverse. A great wrench which fits all chucks is a stout piece of 1/2" thick stick. Stick it in the jaws and make it as long as you like.
