Help!

Ok, I put money down on a Bridgeport Mill, SN: 131234 (on the front end
of the area between the ways above the crank that moves the bed
front/back... missing the MOTOR!! But relatively inexpensive, and
local... so far good.

Has a really old Anilam DRO, condition unknown just yet. (anyone know
where I can get schematics, if I need them?)

But the HEAD has a vari-speed dial on it, the readout is in front on a
dial... the sides are enclosed.

What head do I have here?? ---
I don't have the the thing here yet, so can't post a jpeg (will do need be).
Google brings back junk and little info so far.

ARE THERE ANY SITES WITH DECENT INFO ON MODELS/TYPES/ETC??

AND - What motors/motor + pulley assemblies can I use (assuming I find
'em used on ebay or elsewhere) to run this thing?? (Don't mind a little
bit of blast and fit to change something around...)

Real info appreciated.

PLEASE DO NOT REPLY TO THE ADDRESS IN THE HEADER!!
Direct email to: bearlabs at localnet dot com ---- take note.

Thanks,

Signed slightly panickkkked that I bought a ton of iron scrap... :-)

The head looks pretty much like this one:

http://cgi.ebay.com/BRIDGEPORT-9-X-4...QQcmdZViewItem

pretty sure this is the head... still looking for info about the head,
parts and what sort of motor/pulley set up I can drop in the hole??
Useful URLs too...

Oh oh! Part of the varispeed drive is ON the motor! There is a pulley
with a sliding flange coaxial to the spindle. That flange is moved by
the vari-speed crank. The motor has a spring-loaded flange that keeps
the belt tight. If somebody just pulled the whole motor out, then that
rear pulley went with it. You can certainly get a motor and pulley set
from somebody who has torn one down, but it won't go cheap!

it is almost certainly a 2-J head, if the machine is a Series-I base.
If a Series-II base, then the head could be a 3-J or 4-J, or possibly
even a 2-J, which were often used on multiple-spindle machines with the
T-Ram.

I think that is an old 2-J head. There are a couple different designs,
although the changes are all really just cosmetic. Newer models have
a plate that covers the speed dial, with two slots exposing the current
speed setting. There is a "mask" that blocks the reading for the wrong
High/Low range setting, based on the position of the high/low
range selection. it has high and low speeds marked by a rabbit and a
turtle. The direct drive clutch and the back gear handle are linked to
this by a rod.

One easy solution is to simply buy another Bridgeport mill head. I'm going to
have a clean step-pulley J-head available shortly. It was fully rebuilt about 4
years ago and has had very light hobby use since. Of course, it isn't varispeed,
but then it's clean, complete, solid, quiet and WORKS.

Hey Grant,

If BEAR doesn't jump at that, lemme know when, where, and how much.
Mine is starting to rattle more than I like.

Take care.

there is a bridgeport motor on e-bay for about $10, if I remember
right - if it's not in the current auctions, check auctions that
finished within the last day or so - I'll bet it got no bids and so
you can contact the seller - otherwise, I've seen bridgeports with
lots of non-stock motors (I've been looking at a lot of miills trying
to find what to buy - I got a non bridgeport, but ....

If you need a motor anyway and if part of the varispeed is missing,
would it not make sense to simply scrap the varispeed and install an
inverter duty motor and inverter drive?

Yes. Which is one of the reasons I like the 1J head better. No
clanking as the varispeed pully bushings fail and eat up the motor
shaft, etc etc.

Putting a decent 3hp VFD on a miller is a marvelous thing to do, and
makes it a hell of a lot more versitile..AND allows you to run it on
single phase too.
