Hi, I'm new to the group. I am venturing over from the rec.ww and owwm. I
recently got a Bridgeport knee mill at auction. It has a round ram and short
table and I have no clue what type of head it has on it.

I am very comfortable restoring woodworking machinery and I own a 9" southbend.
However, I am unfamiliar with Bridgeport's. Would you mine helping me out
with the following pics and q's?

To unload it I took apart the motor from the head, the head from the ram, and
the ram from the turret.

Here is a pic of the head without motor:

Here is another pic of the head highlighting a small nub of broken casting.
What was this piece?:

I know it's probably unanswerable just from a pic, but what type of collet or
taper would this head have?:

Here is a pic of the motor assembly. The motor is positioned directly above
the spindle assembly. Of the pics I have seen on the web, I have never seen a
Bridgeport with this type of configuration:

Here is a close up shot of the motor nameplate:

Finally, here is a pic of the ram. The rear of the ram seemed to be able to
accomodate mounting something else. What went or goes on here?

I do not see "Bridgeport" anywhere on the head. Is this a Bridgeport head at
all? If yes, what model. If no, what type of head is it?


Thanks for taking the time to look at this.

Aloha, Russell

If it has 6 grooves in the pulleys, it is the M head.

Some of it looks sort of like the M, but yours seems like it has
just 4 grooves, and then a 2nd level of belts, which looks like it
will give a VERY slow range of speeds. Or, is the 2nd level of
belts for the power feed, on that pulley in front?
It isn't a "C" head, or an M head. Does the Jacobs chuck come
off, or is it permanent? Is the spindle hollow with a drawbar,
or solid?

I hate to tell you this is probably not a milling head, but one made
for drilling, I think.

Howdy, Aloha Russell. What you have there is (most of) a step pulley
head from a Tree milling machine. I can only guess how it found its way
onto your Bridgeport. Somebody probably jettisoned a little Bridgeport
M-head off the round ram in favor of the heavier Tree.

I believe that head would take the seldom seen Z collets. The good news
is the head has a nifty quick change system. The bad news is the collets
are sort of oddball and somewhat spendy from the manufacturer. I was
doing some research on just this dilemma the other night and found
another source mentioned for the collets for a much more reasonable
price. Try:

http://www.toolingsystems.com/univ/

I don't see them listed on the webpages, but you could try calling.

Lastly, the other end of the ram is for holding another head. Could be a
shaper head, an M-head, or another of the many styles Bridgeport produced.

Does not look like a Bridgeport Head. Tree perhaps?
Tree had odd ball collets. If you didn't get any collets, I would watch
for a used Step pulley J Head for your machine. I know you live in
Hawaii, the Government Liquidations seem to crop up a lot there. Might be
pricey buying a used head from the main land.

The tang on the back is for other heads/attachments. Like a shaping
attachment, cherrying attachment.

Looks like where the depth stop was located. This is typically a threaded
rod with round nut and locknut.
