Trying to find a chuck key for this 13mm chuck

[petro1headParticipant @petro1head]

This pilot hole is 8mm but the hole is very close to the teeth.

Only markings are 1-16mm and B16.

One thing to check is that the sleeve in in the correct position relative to the key hole, I had a problem with the key not fitting properly which turned out to be the sleeve having moved. It is only located by friction but should be pushed up to a hard stop.

Ok bashed and a key i had now fits however the action feels tight now so a bit of fetting needed. Many thanks

Bash it back the opposite way, just less than the first time.

It should not necessarily be pushed up to a hard stop (i.e to speak of its location in such absolute terms is incorrect). It is better positioned in a way that the chuck key meshes adequately and the action is smooth.

Channel your inner Japanese carpenter setting his plane and enlightenment will follow.

One of the chucks we have at the museum had poorly fitting key, so I knocked out the crossbar and bored the end to take a closer fitting pivot which keeps the bevel gears in mesh much better.

Is this the AI thread?

Its a bevel gear drive.
if it is loose turn away a small part of the narrow end of the gear and possibly the pin, It will engage better.
