Hello, when I got my Logan lathe it cam with a clapped out three jaw and I presume the Logan four jaw. My problem is they both take a wrench with a 1/4" square snout. The three jaw got rep;aced with a new Bison. Some how I managed to loose the wrench for them. I've been using a 1/4" ratchet and extension. Does anyone have any idea where to find a 1/4" square chuck wrench? I can make one but I have doubts about how long it would last before the square part broke off.
Thanks and take care, Old Time

I would just make one... If worried about it breaking give it a home hardening session with heat. Worst case you end up making another.

... even easier! Machine one from a grade 8 or a grade 5 bolt - you won't "twist" it off. Below photo shows two that used a 3/4" diameter bolt body with a 5/16" diameter handle. Buy the bolts long enough so the head and threads can be cut off.

Why not take a 1/4" extension and weld a T handle on it. The extension will be hard and cheap.

If you want to make your own but are worried the square part will break off, braze a 1/4" lathe tool bit into the end. I've used them to remove the little pipe plugs in the oil galleries of a SBC block without breaking them.
