Subject: Bridgeport milling mill - parts and use manual cd
I have been working to purchase some basic tools to allow me to perform basic metalworking. One of the tools I have acquired is an Old Bridgeport Round Ram mill and one of the biggest challenges I faced after I bought the mill was finding a good source for information about the mill, it's operation, and the various parts and attachments for it. In my search for information I was able to obtain the following documents that I have compiled into a single CD that I am offering to sell to others that may also need this information. The CD is Windows compatible and contains files prepared in PDF format along with a number of photos in JPEG, BMP, and GIF format which should be easily viewable with no special software required.

Note: There are two versions of this manual on the CD. This is an older version of this manual and it contains essentially the same material as the newer M-105H version above but it did have a few differences so I have provided this older version of the manual on the CD as well. Also note this is an assortment of pages from the manual and not the complete manual (above manual is complete) but at one point I was happy to even have these pages!
US Patent Number 2275291: Original Bridgeport Mill
Machine Tool Operating at Universal Angles in Overall Locations
The original Bridgeport Round-Ram Turret Mill Patent is included on the CD. The Patent is 10-pages in a PDF format and includes a great description of the mill with diagrams and figures that provide insight on how the round ram mills are built and designed to work.
The CD also has a folder that contains photos of various Bridgeport Mills and accessories that I have compiled for myself to refer to while working on and with my own Bridgeport. I figure that if I have found them useful, you may find them useful too!
