How do you buy wedges to remove a chuck

[tackit]

I'm in need of wedges that will remove a chuck from a MT2 JT3 arbor. I have #2 and #3 wedge sets but neither wedge set will fit my chuck.. Thanks

You can but you can risk damaging the chuck and spindle. Wedges are cheap, I would get a set of properly sized wedges.

I can find the right size wedges for every chuck but mine, I searched until i couldn't do it any longer and finally gave up. Size #3 wedges are huge, size #2 are too small..... what the hell is a boy to do? . I hate calling mail order houses on things like wedges, they have a way of not listening and send what they think it is you want. I might fill the truck and travel to Fastenall if they say they have the right ones. I can take the chuck with me.

Cut and weld?

Are you sure it is a JT3, I could be a JT33 which is in between a JT2 and JT3.
I would just mill out a #2 set of wedges to fit your application, an buy a
second set of #2 for replacements.

What kind of chuck do you have on the arbor?

you may have to drill a hole thru the arbor and wedge something, maybe the #3 set?


other option, what I did on a 1/2" Jacobs chuck I opened the chuck, drilled a 1/4" hole thru the inside to the arbor, used a hardened drill blank pushed on the arbor.
Had too stand on the handle of a one ton arbor press and hit the top of the ram with a big hammer.

can you post a picture.

Here are pics of the 3/16 X 3/4 keyed chuck fellas.

GWIZ it might come to the way you did it if I can't find the right wedges.


What I don't understand is the huge difference between number 2 and number 3 wedges.

Number 2 wedges are to closed and won't fit around the TJ3 arbor, and number 3 wedges are at least a 1/4" to wide".

If number 3s are larger than number 2s, number 6 wedges should be larger than number 3's right? Yet I can't find any wedges between number 2 and number 3s, and the only other numbers I have found are a number 1 and number 6 at Shade's MSC link.

I'm going to set just the arbor in a container filled with ice cubes and see if the cold won't make it so the arbor's tang will come out by lightly taping on the top of the chuck with a rubber hammer.

Looks like you need a large shoulder.
