Default Bridgeport help with pics and q's

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:

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.

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
