I have an opportunity to acquire a full set of H 3 collets for a very
reasonable price. Will these fit either an Enco 13 X 30 or and 11" Logan
lathe? Can a closer be acquired or built to adapt these collets to either
of these two lathes?

Hmm ... I don't see an "H 3" collet listed in the 25th edition of
_Machinery's Handbook_. I *do* see a "3H" listed. A little smaller
than a 5C, with a 7/8" maximum size round stock, instead of 1" through
or 1-1/8" short grip for the 5C.

Bearing diameter is 1-1/8", so the question is whether you can
pass a drawtube of that diameter or a little bigger through the spindle.
If you can go to 1-3/8" through the spindle, go for 5C collets instead.
It'll be cheaper when you need square or hex collets for a particular
project later.

However -- if it is truly an "H 3", I would be interested in
hearing more about its dimensions. Without those, no bets. I would
guess that the 13x30 would handle 5C collets, and maybe even the 11"
Logan (depends on which one I think, and Scott Logan could tell you
that.

Good Luck,
DoN.


Hello Don. My Logan #922, 11inch Q.C., takes 5C collets very nicely.
Sure are a handy chucking method.

Great! So does my 12x24" Clausing.

Absolutely agreed -- especially with a lever style closer, which
mine has.

Envy is such an ugly emotion grin. Mine is the 'twist to tighten'.
Not nearly as quick, but works. Sure beats setting things up in the
4jaw.

Well ... I'll bet that *your* lathe came with a tailstock. I
had to hunt one down that fit. (Granted, what it *did* come with is
very useful for some things -- but still a tailstock is quite useful for
general working. (What it did come with was a bed turret.)

Enjoy,
DoN.
