    Default Bridgeport Series 2 Riser Dimensions?

    I have riser that I believe is for a Bridgeport Series 2?

    I don’t have a machine that I can measure the bolt pattern.....anyone have a picture or dimensions of the series 2 bolt pattern?

    Another question, does the 4 hp. Series 2 and the series 2 special share the same bolt pattern for the turret?

    I looked online and haven’t been able to come up with anything!

    Any help would be appreciated!

    Yes, the bolt hole pattern for a Series II and Series II Special are the same. The turret on a Series II Special is different from a Series I turret, but the II and II Spacial have the same pattern.

    Thanks Jon!

    Do you happen to have any dimensions or pictures/literature to help identify this riser?

    I will post pictures later, will see if that helps with the identification?

    I have two Series II Specials here that have 6" risers. Since the risers are on the machines it's difficult to get measurements without removing them. But from what I can measure the 5/8 dia. bolt holes appear to be 9.25 between centers front to back and about 10.25 right to left. If time permits in a few days I may try to remove one to get a detailed layout of one if you still need it by then. The spider is code number 2-15-0008 according to the manual.

    That’s great info!

    Thanks for the offer, but don’t bother taking the turret off, if you could take a measurement of the circumference of the riser, I think that would be all I need!

    Thanks again everyone!

    Looks like 55" on the circumference. Also it looks like I may be off on the holes a bit. If you need those I can recheck tomorrow.

    Thanks for the dimensions, the diameter matches, 17.5 and the bolt pattern matches what I have!

    Looks like this is in fact a Series II riser!

    Thanks again!
