Help indentifing a machine taper

See if this publication has the info (~1.8mb):

Jacobs made an oddball "2 short" that some import drill presses use, but your dimensions don't seem right for that one (shrug).

Hi Leon;

Thanks for the reply, however I've checked against all the standard machine tapers I could find, including the Jacobs list from that site with no luck :-(

I'm starting to come to the conclusion that it is a non-standard attachment.

Thanks again

Joel

Lots of taper standards out there, not a lot of them currently in use, though. If it's an Asian drill press, there were some imported that had a lesser-used taper, was discussed in.r.c.m. years back. Chucks with that taper were available back then from a few suppliers, were expensive though. If you got a good deal on the thing, you know why now.

It's an Australian machine which I got for the hassle of moving it, so even if I can't find a chuck I'm up one motor and 200+ Kg of scrap steel :-)

Cheers

Joel

there are places that can regrind a taper - some places specialize in this type of work - and I know there are machine shops in Australia - so it might be worth looking around and see if you can have it reground to a standard

Dumb question/thought... but have you verified that the female taper in the drill press actually matches the chucks taper well? Maybe somebody just jammed the wrong or a modified taper into it and it worked good enough for them (shrug).
