   Hi Fred,

Did you make your thin washer from brass shim stock? Thanks,

I did that with a washer made from thin shim stock and never had a major problem removing a chuck on my 12" Clausing.

I don't think you want the washer too thick in case somehow it would affect the register of the chuck when installed.

Is there anything that can be done to prevent a chuck from sticking?

 

Other than not socking it tightly to begin with.

Mike:
Here's a few cartoons I sketched up and pics for you to make your accessories.
While you're set up to do the 45 degree way grooves, you might as well whittle out a dial indicator mount.
As to the knobs for the indicator mount, no particular dims. Just carve them out to suit your needs. *The knurled knobs are a ton faster than fiddling with allen wrenches to move the mount around.
Have fun !

Clean the internal threads on the chuck, external threads on the spindle, and lightly lube it every time you remove the chuck, AND every time you reinstall it, cross everything you can cross, and pray to every deity you like. It will at least help. So does holding your tongue just right. ;)

If you plan on machining steady rest bases, your depth of cut for the V is about 1/4”.  I just checked my tailstock way template I used in order to re condition SB 9A and 10K.
 
I measured a depth of cut of 0.247” on the V.

Re: stuck chuck

Chips
 

There are so many variants of these lathes that I'm sure as pointed out this method won't work on every one. On this one there is a big cast lug on the bull gear opposite the locking pin. I imagine it was added to the gear casting for balance. The forces to unscrew the chuck aren't very great. With the brass rod shown, a little pop on it with the palm loosens it. The enclosed headstock casting is at least 1/4" thick so it has a lot of mass to absorb the impact.


Re: stuck chuck

rrwf@...
 

Well, here's one more.  I didn't like the idea of stressing the jaws by using them as a pressure point, and, anything that involves the backgears was a non-starter.  I finally found two strap wrenches that use woven cloth for the strap, not the rubber type you find at Hardly Finished or Home Depot. The woven cloth straps, once broken in, do not have the problem of stretching on each application of pressure.  Granted, there is a minute amount of give but nothing compared to the rubber type.  I wrap one wrench strap around the large cone pulley and use the other on the chuck.  I rotate the chuck so there is enough tension to hold the wrench on the pulley after its handle comes to rest on the casting.  I then heat the back plate near the threads using an electric heat gun.  After a few minutes, I put as much tension as I can on the wrenches and use a deadblow hammer to work the chuck loose.  This allows for a one man operation, but if help is available, a lot more tension can be put on the chuck by one person as the other works the hammer.
