    Default Odd bridgeport m head?

    https://flic.kr/p/2bmmQ58

    Anyone know why this bridgeport head has a diiferent casting with 3 exra allen bolts added? There had to be a purpose for them.. And theres no serial number stamped on it.

    The casting is split to the quill to adjust the pinch of the bore.
    There is felt in the split line, which has been partially painted
    over.

    It's amazing how bad some of those machines look on the outside; yet they sometimes look like new on the inside but still not very comforting when all you can see is the outside.

    I had a camel back drill press with a split casting. The casting was bottomed out and the quill still flopped around some. She was well used. Hotdog down a hallway.

    The split casting is pretty common on drill presses and such but all the M-heads I've seen do not have a split casting. Maybe this is just a very early version??

    Are you sure it's a Bridgeport and not a clone? It definitely looks like a BP from the photos but... ?

    It looked to me like something bolts to it, like a steady bracket between 2 heads on a tracer mill.

    I looked at some of the machinery museums that had photos of very early bridgeport milling machines. None had heads with split castings. Really strange....
    It's definitely a bport head. The upper housing is a bport. Although the tag with the serial number is missing.
    I looked all over the Internet for m heads. I saw a few that were odd. One had a different lower casting, with the fine feed positioned differently. One had an upper casting with the motor entering through the bottom of the upper housing.
    I removed the paint from the side of the casting. You can clearly see where the casting is split.
