    You must be very pleased, those are text book blue markings. You can get tapered socket wipers on ebay which are handy. I got a couple of BT30 ones for the R8 spindle of the Tom Senior mill. The angle of taper is similar and there are no pins in the bore.

    Hey! Thats rude... I would have given you a Factory spindle that I have.

    So the grind looks good on camera. Pollably much better in person. Nice work.

    Now Bearings! Setting bearings can be difficult. JR

    I got my spindle back from C&M. It looks like a work of art, hopefully it will perform as good as it looks. It might take me a week or more to get it installed as I am in the process of redoing my Centroid.

    C&M shipped the spindle and just sent me an invoice due in 30 days. Very impressive as I am not a big company, but rather just a nobody.

    What defines it as a Boss 5 - the CNC? rigid ram? era?

    Mine is still in an extremely protracted phase of converting from the cranky old steppers to Yaskawa servos. Really embarrassing how long its taken, cripes, I had hair back when I started it! My goal is to have it running before additive machining makes CNC obsolete...the race is on!

    electrical box coming along....slowly. to cram as much in the shop as I have, things like access to electrical boxes are less than roomy. Still, some progress






    Hahaa, haa. Mac cant keep track of a tool

    Id call him an Idiot but have been told I cant do that. JR Idiot "_

    A very high percentage of replacement bearing from John Deere &Case New Holland are made in China,not cheap to buy!

    Yes, I know. That's because those companies have the bearings made to their specs and you're buying those bearings through them. Big markup.

    Yes, that guy NC cams was a real perfectionist, his nickname came from his trade, he made camshafts for Nascar. Unfortunately, he passed away a few years ago. There are a couple other guys on that cnczone bridgeport forum that worked for bridgeport as well and really know their stuff.
    Yes. Dont forget about the other company.. JR

    I had a Series 1 BOSS 5 before my current Series 2 BOSS 6. The Series 1 BOSS 5 did not have the rigid ram, so that is not a defining feature. Best I can tell, BOSS 1 thru BOSS 6 were primarily defined by the use of stepper motors and a DEC LSI-11 based control. I believe that the BOSS series were just incremental improvements, mostly to software. BOSS stands for Bridgeport Operating System Software, and I think the numbers indicate a major control revision. The machines may vary a bit, but there are no real major revisions to the iron. The Series 2 BOSS machines were a complete new iron design for the BOSS series.
    good info, thanks

    Thanks. It looks like I will be sending my spindle there tomorrow.
