Does anybody know what the "TJ" means in connection with a series 1
Bridgeport mill? It's suddenly become of interest to me because I
bought one today! Woo hoo! I hope and pray! V

After noodling around the net I think that "TJ" was a typo and should
have been "1J" or "2J". The mill is a Series 1 but has a DRO and
power feeds. At this point I'm trying to determine whether it takes
R8 tooling or something else. I get the impression that R8 was
standard in the old machines and 30QC and some other "30" designation
came later, in order to facilitate tool changes during CNC operation
sequences.

Is this about right? And, since I don't have any tooling anyway, does
it make a mousie's patootie? Or should I be doing "hail marys"
praying for one or the other? V

Chances are overwhelming that it takes R8 tooling. Congrats. Let me
know if you are looking for a free PDF manual

R8 tooling is generally less expensive and more widely available.
As handy as the collets are, you will most likely be happier with
a weldon [set-screw] style end mill adapter as these are almost a
quick change tool holder. If you use collets [or adapters] you
won't need the full set, just the 3/8, 1/2 and 5/8 sizes for most
tools. On occasion a 3/4 can be handy if your tooling has a shank
this big. If you use the collets get the combination wrench and
hammer.

sites are for example only and most mill supplys should stock
(possibly at higher prices).

In many cases on a "pre-owned" machine the draw bar threads will
be "knackered", and may damage your new collets and end mill
holders. These are inexpensive. [several sizes for bridgeport,
measure the old one]

I suggest you get Edwards book "Turret Mill Operation" as one of
your first items. Filled with good info and hints. It will more
than pay for itself.

In order to minimize your tooling costs take a look at the insert
end mills that use TPU/TPG inserts.

I've not heard "TJ" applied this way. Nor any standard spindles other than
R8 on J's or 2J's. Perhaps this is a clone, not a actual Bridgeport?

I picked up a Bridgeport several weeks ago. Mine has the "Kwik-change"
tooling spindle. I did a bit of research and came up with a couple of
places that might help you ID your Bridgeport better.

http://www.machinerypartsdepot.com/s...age/45029/site

The above links helped me identify my Bridgeport as being built in 1984.
They come with several spindle types, R8 and Kwick-Change are two. I
think there's one or two more. The Kwik-Change tooling is whore house
money, so hope you have an R8 spindle.

Iggy. I would truly love a free PDF manual. In fact, at that price,
I'l splurge and take two! Thanks! However, I will need to send you
my email address. It is vtuck followed by an integer that is greater
than one and less than three wink wink. Then a secret symbol that
horses couldn't drag out of me is an ampersand. Then yahoo dot com.
I had to give up my own damned web page because it got so overrun with
spam as a result of posting to these groups. Die spammers! Sweetly,

Thanks to each and every one of you, for your continued generosity
with your knowledge, which is stunning, and your helpful spirit, which
is awe inspiring. I'm making plans to go get the mill early next
week. V

It depends -- (assuming that the 'T' was a typo for '1' or '2').
I have a CNC version of the series 1 with a 2J head which has the
NMTB-30 quick change spindle. I don't think that you will find a 1J
with that spindle, however.

Enjoy,

OK, a 1J has a 4-step pulley, plus back gear
selection, for 8 speeds. The motor is typically 1
Hp. The 2J has a vari-speed belt drive, and
typically 2 Hp, but early ones were 1.5 Hp.
The mill is a Series 1 but has a DRO and
power feeds. At this point I'm trying to determine whether it takes
R8 tooling or something else. I get the impression that R8 was

No, it is just choice of the purchaser. The R-8
is the most available and cheapest, you will find
fully tooling up a 30 taper machine may well cost
more than the machine itself, even surplus. The
NMTB 30 taper is a constant taper, but much
steeper than the Morse tapers. The R-8 is mostly
straight, with a short taper right at the end.
Look on the net and you should be able to find
pictures of both to compare.
