I'll gladly buy one, but no one seems to make Morse Taper 2 end mill
holders
for 3/4" shanks any more.



Nobody makes 4 inch dia x 1/2 in shank silver & deming drills either,
go
figure....

I gather that you think a 3/4" end mill holder will put too much torque
on
the MT2 spindle. My primary application would be for occassional fly
cutting of aluminum with a 3" insert fly cutter with modest DOC. Is that
too much to expect?.


For the tool manufacturers, apparently yes.........'modest cuts"
no......"very light".....perhaps......realize that many shops would fire
your butt due to the hazard and possible liability....

I'd have been fired long ago if I did this for a living. It's mostly just a
hobby for me, though some parts are made for work in an R&D environment.

But since you seem so determined, why not just turn the shank down on your
flycutter, or maybe even make up a new flycutter--one that actually 'fits'
the holder you already got ???

The flycutter can be seen here, in the second picture down from the top:

It's got center holes on each end, so I suppose it could be turned between
centers. Getting a dog leg on the flycutter end might be a problem given
the radius on that end, so it might be better to hold it in a 4-jaw chuck.
From an engineering standpoint, though, it seems that a 3/4" EM holder is
simpler and at least as cheap a solution if machining time is considered.
Then too, I'd also like to use (or at least try out) the Tree boring head
and I'm not about to try turning it's 3/4" shank down to 1/2".
