We have a problem at school, one of the Bridgeport mills
the power quill feed did not work. The "push-pull"
direction reverse pin in the center of the hand crank
for fine feed just pulled clean out. The pin hole in the
end obviously was not doing whatever it was suppost to do.
SO! dug out the file folder and looking at the various
picts. and then taking apart the various bits to get in
to the area no problem untill I get to the clutch that
should be free to slide in / out and engage one of the
two bevel gears (that the pin was suppose to operate)
was frozen tight on the shaft. with the front miter
gear off it is not obvious how the shaft with the other
miter gear the clutch and the worm on the rear end can
ever be pulled out because the "input" bevel gear
(the one that is vertical) won't let the drive shaft
come out past it. Removed the "gear shift" box cover
with (the carrier that slides the cluster up and down0
and I don't see any way to either move the gear up or
remove it. It looks like the clasic "catch 22" sit.
(Incidently that gear box is a clasic manual crash box)
Has anyone been in to that part of a Bridgeport?
This is, I guess it's called, a J head, at least the
serial no. is J236648 The book we have is called
"Operating Manual 1962" the pictures of the
"Feed Transmission Unit" on page 27 and
"Quill Unit" on page 19 ff
Here are links to the two page pictures. My Photobucket
is not working for some reason with this browser.
I am having to use FireFox since my up grade of SeaMonkey
crapped out on me.(no bookmarks or e-mail got copied)
