Where do we keep the chuck key for the small 4-jaw lathe chuck?

Where do we keep the chuck key for the small 4-jaw lathe chuck? Or do we have one? The one to tighten the jaws. It’s about 1/4" square.

Mike, I think we have one in the teachers cabinet. I believe its the same size as the 5c collet chuck we have for the Shark lathe.

I’ll check tomorrow. Thanks.

No joy finding chuck key for the small 4-jaw chuck. I found the 5C collet chuck but did not see a chuck for it. Is the small 4-jaw not used in favor of the large 4-jaw? I can certainly use that but it’s heavy.

I measured the square hole on the small one at .29". If that’s right it should use a 9/32" key which are not terribly common.
