Drill Chuck Arbors

[kendo]

Hi Folks
I have just acquired a jacobs chuck in very good condition, but minus
the arbor.
The writting on the side of it reads 34-02 0-1/2in 0-13mm 2 taper
and my question is this, how do i determine whether it is a
MT2 - JT1 MT2 - JT2 ect.
For use on my lathe which has a MT2 tailstock.
Ideally i would like to use it on my mill, but my mill is a MT3 and uses
a 12mm draw bar. not sure if such an adapter exists scratch.gif

Any Help you very experienced folks could give would be very much
appreciated

well you need a 2mt or 3mt to 2jt
look here http://www.use-enco.com/CGI/INPDFF?PMPAGE=492&PMITEM=240-2722
$5.00 US will get you one.

or this http://littlemachineshop.com/products/product_view.php?ProductID=1805&category=

Maybe one of the UK guys can give a UK source with the metric draw bar thread. but I venture to say what you are looking for does exist.

Ken I'm sure I have a MT2/JT2 arbor here somewhere. I also have a MT3 half inch chuck. If you pay the postage you can have both, but you need to find yourself a chuck key. You don't need a drawbar in your mill for drilling just don't try putting a milling cutter in the drill chuck.

Not sure why a MT/JT arbor with a drawbar thread is needed but you can get them here:

And if you change your mind and need it with a tang they sell screw in tangs (half way down the same page)!

Hi Guys
Sorry I've been a little while getting back to you, been away visiting
family.
Just like to say a big thankyou for the replies.

Tin thanks for the link, i have bookmarked the site for future use.

Vic thanyou also, for your link another very handy site to know.

'' Not sure why a MT/JT arbor with a drawbar thread is needed but you

In Answer to your question Vic. When i bought my mill it came fitted
with a 5mm to 20mm chuck, this chuck is fitted with a MT3 arbor
which is pulled in with a 12mm draw bar.
If that makes sense?
Being a 5 to 20mm chuck, means i can't use smaller drills than 5mm,
which is a real PITB ;D

Peter, thankyou very much for your very generous offer, i would like to
take this offer,and will gladly pay the postage, i will send you a PM.


Once again Thankyou all very very much for taking the time to reply


My Very Best Regards
Ken

PS: Also like to wish all at HMEM all the very best for 2011.
