4Jaw face-lift

[Suzuki4evr]

I've decided to give my 12' 4jaw independent rusty chuck a bit of a face-lift today. I only took off about 0.005" on the face and OD.




I just don't know why I have never noticed the T-slots on the chuck,and for the life of me I can not think of a way you can use it seeing that this is an independent jaw chuck. If someone can give some ideas on when it would be suitable to use the slots instead of jaws,that would be great. I have a feeling I am going to kick myself when the responses come in.

You can put bolts and studs in the slots to use for part stops.

Also use the slots to bolt parts to chuck.

I just watched a video by Joe Pieczynski where he drilled holes in his three jaw for mounting standoffs for creating precision parallel surfaces. The standoffs were mounted to the chuck and faced to the proper height for a second facing operation. The Tee slots would accomplish the same thing.

I guess that would be parts that you can't necessarily clamp with the jaws right?

I remember, I've seen that one a whileback. Good idea

Yeah, you're essentially using the chuck body as a faceplate, jaws removed.

Remove the jaws and you have a face plate. Use it any way you would use a face plate such as holding a fixture for repetitive operations..........Bob

Agreed, it has the advantages of a face plate, and a 4 jaw. Gives more flexibility in mounting and securing work pieces.

Also used to bolt counterbalance weights to the chuck to reduce out of balance on workpieces, like when turning crankpins on a crankshaft.
