How to attach a quality drill chuck to a Morse Taper 2 arbor?

But to what end, since you are not supposed to pull a chuck off an arbour whilst it's in a machine and the MT has standard provisions for removal on most machines. For machines with no draw bar, wedge slot or auto-eject for the MT a chuck which held it's taper better than the arbour might be a boon as it would reduce the risk of being left with an arbour stuck in the machine :D

.

Properly designed machine spindles/quills incorporate extractors, and/or slots for wedges.

Choo Choo did not say whether the chuck was keyed or keyless. If keyless be sure not to seat the taper using a press. That can expand the body of the chuck enough to lock it up. Don't ask how I know.

[you do make a good point though]

Morse taper originally was thought of as 5/8 inch per foot (0.625). As precision improved, it was realized that the existing patterns did not quite conform to this ideal. Rather than orphan equipment already in use, the slightly-off specifications have continued to be used

The above is quoted in several places as a reason why Morse tapers are not all exactly the same angle.

I am totally amazed at the length of this topic. I never think twice about putting an MT2 taper into my Rohm chucks. Just push the chuck taper into the chuck and the MT2 taper into the tailstock and go drill something! What is so difficult about this? Or am I really missing something?

Yes, I hoped you might have noticed I stated that before observing that the only advantage of your being right would be for machines which do not, the ML7 tail stock is the only instance of absence which comes to mind

:D

Nick,

I did notice what you wrote ... but I felt the need to include the phrase "properly designed"

I have nothing more to say on the matter, unless and until I find supporting evidence for for my hypothesis.

Choo Choo if you read my post of 02/06.2017 timed at 10:53:28 you will be directed to Google "Little Machine Shop".

If you then click on "Reference", you can view a series of charts giving dimensions of Tapers, including Jacobs.

I did that although not from Tracy tools I should add. The chuck wobbled all over the place once in the mill so I had to bin the arbor and buy a new one. Guess I was just unlucky in getting a Friday afternoon arbor. The chucks not bad but not as good as an Albrecht.
