Drill Chuck - getting it off the arbor

[Ben17484]

I have a nice keyless drill Chuck on an MT3 arbor, that I’d like to fit to an MT2 to use it in my tailstock of my lathe. How is best to seperate the drill chuck from the arbor? I assume it is possible?

The best way is using chuck wedges. They come in different sizes.

Thank you. I’ll take a look for some.

they can be expensive. You can make them yourself with a mill. They won't be hardened unless you use material that can be hardened, but for single use you will find it works. I have a set that I made for a single use and have used it more than once.

You'll need some really strong wedges if the chuck is threaded.

It had occurred to me to try to make them. It seems they are just a wedge with a u channel milled in to them?

Correct.

Make sure there is no screw hiding inside the back of the chuck.
If there is a hole in the back of the chuck and wedges don't do it you can try drifting it out.
You also might be able to drill your own hole, ideally by putting the chuck into a tapered lathe spindle/adapter.

I suggest not trying this. The keyless chucks I have seen have the jaws adjusting screw there, unlike Jacobs chucks.
