Every attempt has been made to keep these images at a reasonable size, while still maintaining the ability to see what your looking at. Therefore they may view larger than your monitor is capable of showing. For these images to print on a single sheet of paper, it is recommended that you save the image to your hard drive, and print it through a separate image viewing program and not through your browser. To download the image, right button click on the desired link, select SAVE TARGET AS, and download it to your hard drive. ACDSee works extremely well as do other image viewing programs. I can not support any problems you may encounter trying to print or view these files as I only use ACDSee and Photo Shop, but they will print and view with other programs if your settings are correct. All images will fit on a standard 8 1/2" x 11" sheet, with the exception of the BASIC MACHINE. All part numbers and images were scanned from a Bridgeport Operators Manual.

** In the works is a Bridgeport repair and troubleshooting page, with how to's and other handy nice to have information. **

Ever Wonder What Indiviual Components Weigh?

I have the instructions on changing the belt on a Variable 2J. If you need them just ask.


Extend the quill a little over 3" and lock it.
Place a 0-1" dial indicator so that it rests against the top of the quill.
Adjust the table to read a preload of 100 thousandths.
Crank the table down exactly 3" using the dial on the crank.
Multiply the reading times 3. (the indicator is now ~9" below the pivot point
of the head and you read 1/3 of that)
Adjust the head in the opposite direction the indicator moved by your figured
Check your work by doing it again, it should be dead on.
This works for both directions.
