    I know the cost of those grippers is high, but I think it's worth it. Going off my 2001 30 taper spindle I would say you most likely need to pull the drawbar out of the spindle to replace the...

    That's a nice photo showing the difference between grippers/fingers and caged balls on pull stud design. Gripper on the left, caged balls on the right.

    It's not like they are breaking from too much drawbar tension so as long as you don't machine too aggressively so the tool holder pulls out of the spindle you should be good.

    Those divots in the Maritool pull stud are absolutely abnormal. I have pullstuds that are up to 17 years old in a 30 taper mill with around 500lbs drawbar tension and the divots are no deeper than...

    I certainly won't say the Maritool knobs are spot on BUT from what I have gathered the cause of the pull studs failing is when during a cut the drawbar tension is overcome and the tool holder pulls...

    I for one am really curious as to what the spindle grinder uses for a gauge to check the spindle bore contact with? Spindle tapers are slightly shallower than tool holder tapers so the mouth...

    Most 30 taper pull studs are breaking when the tool holder is getting pulled out of the spindle some and rolling around putting a side load on the pull stud. If you creep up on too much cutter pull...

    Yeah, my eyes bugged out at 2:20 in the video. I had to back it up and watch it a few times. It looks like the Y axis blocks are touching too. At least the blocks and rails are certainly oversized...

    50k is spinning pretty fast so at first be aware of the spindle temps. All I found said "air cooling". What is the warmup routine for the spindle? Those certainly are cute little holders.

    Touch off like any tool and comp the .005" tip extension on my Harvey .02" corner rounder. I find comping the tool to be better than programming it in, for one thing, it is way easier to remember.
