I recently aquired a 1908 Monarch with a siezed 3 jaw. I've given her some pretty big blows and that chuck will not move.... Any suggestions would be greatly appreciated
Hello Mat. What I have a similar to yours but mine says craftsman on it and there are no levers in front of the gearbox for thread cutting. Mine is older I'm assuming as there are no levers, you have to achieve the correct feed my changing gears supplied with the lathe. I really don't know how to set it up for thread cutting but then again I've not had a need for it. The other problem I have is my chuck is super stiff. I mean the T handle is almost unturnable by hand and I don't know what you would do to service it. I would assume it would be to simply disassemble it and clean everything but I really don't know that for sure.
Hi - great video - my only concern with using oil on the spindle threads would be it will cause an over torque of the chuck during use? This over torque could cause the thread to stress and fail. I am not an engineer, only speculating my thoughts. For the same reason you want the threads to be lubricated for removal it will work against you also by over tightening and exceeding the allowable torque initially. What are your thoughts on this point of view? Thanks for sharing.
Thank you! You may have a slight amount of over-tightening, but due to the seize of thread there shouldn't be any issues with stress. A 3/4" (19mm) bolt can handle around 200ft lbs of torque, that's much smaller than the spindle thread and it shouldn't be seeing that much force when cutting.
I’ve got a Clark 1027 and I can’t get the chuck out. Also do my jaws need to be in the machine when doing this? My jaws don’t like going in all together and yes that’s problematic.… haha help
My 1921 Hendey saw me watching this, I can feel it laughing.
Holy, 100 years old and sounds like still in use! If machines could talk.

Thank you so much Paul!

Can you put the Allen wrench in there and then just turn the lathe on?
No, there is too much risk damaging the lathe.
Thanks 👍
You're welcome!
Very nice.
Thank you!
It is ok after getting the chuck off to clean everything good the put some never seize on it
Oil would be better. If you run the lathe in reverse, the anti seize may allow the chuck to come off during operation.
Were you a commercial pilot at some point in life? I ask 'cause I'm getting a strong passenger pilot vibe from you...
Unfortunately no, but I would love to get my pilot's license if that counts lol.
That lath looks like what I have
Awesome to hear! They're definitely becoming rare and they're extremely well built.
