Trouble call question
Just found out some new information
From Teacher
One of the students opened the jaws too wide and they fell out. I think they tried to put them back in the wrong sequence. There is one still out the other two are at different depths.
I pulled hard enough on the spindle bars to bend them and cannot get it to budge.
From tech
Denford Admin You stated that he can tap it with a hammer to loosen it up
I am going to suggest that he remove the jaws and inspected them for damage. From what I'm understanding they can come out and be put back in
Right?
Thank you for the help!

From memory, I think the chuck is marked A B C and the jaws 1, 2, 3
You'll need to get that bit right first and also make sure they are putting them in the right way round - internal and external jaws will be different.
If all else fails - get a new chuck from Sherline - https://www.sherline.com/3jawpg.htm only $100 !

Microturn lathe for sale
Hello. I am posting a Microturn lathe on eBay. Friday November 3rd, 2006.
With most chucks the sequence to fitting jaws is.
Take all jaws out of the chuck.
The chuck body and jaws will be marked 1,2,3 or similar.
align all the jaws with the slots then turn the chuck in an unlocking direction
as the scroll passes each jaw you will feel the jaw lift then drop
at the point where jaw 1 drops start to wind the chuck the other way. Jaw 1 will catch on the scroll first then jaw 2 and finally jaw 3.
If you then close the chuck fully the jaws shopuld meet in the centre.
