Wanted: Arbor MT3 dawbar (3/8-16) to JT33

[slow-poke]

I already have a new 1/2" JT33 drill chuck, however I need the arbor to use with my milling machine.

I will also consider a drill chuck with a MT3 drawbar(3/8-16)

You may have to drill and tap an arbor to get the 3/8x16 thread for your drawbar. I am not sure how you will mount the JT33 end for the drilling and tapping. Easy to cut off the tang with a hacksaw.

I do not know sources of machining tooling in Canada. A US link to illustrate.

If you can machine a JT33 taper, you could look for a machinable arbor like this one. I use these in wood turning jigs. I mount an MT3 sleeve in a chuck - straight on the OD, MT3 on the ID. I insert the taper in the sleeve and machine the other end to my desired diameter. I only need a straight end so easier than machining JT33 taper.

I would machine the end straight. It is not going to run true as-purchased, I would then reverse in the chuck to drill and thread, then remount in the MT3 sleeve to machine the JT33 taper.

I just bought a JT3 5/8" chuck with 3MT off of eBay that is set for a 3/8 draw bar.

I checked a couple places online, but only found stuff that would need to be modified.

Probably the simplest is this:

you would have to cut off the tang and then drill and tap it yourself.

Good luck!

EDIT or maybe not.......the description lists both "tang" and draw-bar, but the selector does not let you choose!!!

I sent the seller a question, to find out.

Wow, that's a smoking deal!

But if you still need the JT33 to MT3 arbor with 3/8"-16 draw bar threads, LMS sells them. http://littlemachineshop.com/products/product_view.php?ProductID=1806&category=
