You cannot fit a MT3 spindle in that quill without an inordinate
amount of work.

Define reasonably priced.

Hey Byron,

Hmmmm.... is that possibly a typo? I won't say you are hoping for
something that can't happen, but my "M" head has only MT-2, and I've
not seen any reference to MT-3 being available. I don't think the
spindle is big enough for an MT-3 to fit in the diameter of the
spindle available.

And I don't recall ever having personally seen a threaded MT-3
COLLET, which is required for the drawbar-pull, although I suspect
that they do exist.

Good Luck. Take care.

I have a set of MT3 collets that are rear threaded, I think these are from
sort of older import mill.I had used them in an old South Bend 9" to hold
some work. No way to pass stock thru, but good for holding short parts. It
would seem the cost to regrind your spindle would be better spent on a J
head.

Hey again Byron,

In their 2001 (note that year!!) catalogue, KBC Tools listed a 3/8"
BS-7 end mill holder as KBC # 7-156-010, and under another number a
shell mill arbor. Not in the latest, or on the webpage now though.
Seems like B&S tapers have run their course.

Just for fun, I did a cad drawing of the B&S-7 laid over an MT-2.
WOWWWWEEEEE!!!! Are they CLOSE or what?!?! I never realized that
before.

The MT-2 has a taper of 0.59941" per foot (for approximating only,
say .6"per), and the B&S-7 is 0.50147 per foot (say .5 per), so you
can see that the MT-2 tapers "more" or "faster" than the B&S-7. That's
like only 100 thou over 12 inches! Not very much difference. Not sure
I would see that difference unless they were laid side by side.

Problem is that the "small end" of the MT-2 is smaller than the small
end of a B&S-7, by 28 thou. The B&S-7 is .600 and the MT-2 is .572.
So, even though the grip lengths are 2-39/64 for the MT-2, and 2-7/8
for the B&S-7, the point where each exits the socket is .700 for the
MT-2 versus about .720 for the B&S-7.

OK....supper interuptus...so I forget what I was doing, but I hope you
get the idea.

I think you could redo the spindle you have to an MT-2 with very
little trouble. I won't presume to tell you how, but it looks like a
couple of ways to do so, either by cutting what you have, or sleeve,
or sleeve and cut. It would require a lathe that has a 2-1/2" travel
of the compound, and 3" would be better.

I do know that even the MT-2 collets are in a short list of sizes, but
they aren't real hard to either make from scratch, or turn from soft
centres that flood the market.

Take care.

Typo was it! ( I certainly have ffs(fat finger syndrom)) MT 2 is what I
really would like to find for the M Head but could do woth BS #7 tooling as
I have found some stuff on EBAY but that is always buyer beware as I got a
lot of both MT and BS but nothing really in the way of collets which is what
I really would like, a Set of Collets I can deal with the rest of my
situation, of course I guess if all comes to the worse, I could make a set
on the lathe and just use the taper tooling I have I just wanted not to have
to do that.

Thanks there guys much appreciated


as far as a fair price? MSC had a fair price on BS Collets several years
back but they quit handeling them. Can't find any now ones any more in my
searches.

B&S #7 tooling comes up on ebay quite often. I just bought a 1/16" collet to
complete my set. The seller had a bunch of collets for sale. They went for
from .99 to 16.00 each. There's a 3/8" end mill holder for auction now. I'll
probably make a boring head and an arbor for an Albrecht chuck or maybe just
stick with straight shanks and use a collet.
