    Cut off tools and Inserts tip on breaking inserts.

    I really do get good fast cutting though, nice curls as well. Don't know the speed, I am using the sb9 with the leather belt, motor to the big pulley is on the fast setting and the belt in the center position. So it's not slow or in back gears. I could try the fastest speed. I just know I am...

    Cut off tools and Inserts tip on breaking inserts.

    The inserts I was using are .086 When the last two go I will have a new HSS set up. I will keep tabs on how many cuts I get before the next one cracks.

    Cut off tools and Inserts tip on breaking inserts.

    The snowplow analogy is perfect I think. There is 300 acres of farmland in front of my house, I have a 10 acre hobby farm and heavy clay soil. When I bought this place i bought a tractor and a 2 bottom plow, pigs, cows, chickens. I grew an acre of corn to feed the animals. That 2 bottom plow...

    I was looking for a new cut off tool because the inserts on the one I am using are breaking. On another forum I found this little hint that may help others with the same problem, I am pretty sure it is the reason for my problem. "Important. When using carbide DO NOT use intermittent cooling...

    10-24 broken bolt in expensive injection mold

    Forgot to ask, exactly what brand of extractor are you referring too, do you have a link? I took my truck to a guy that had some German made extractor for spark plugs that he was able to extract completely rusted off plugs with after I mucked it up trying to get them out with the dumb...

    10-24 broken bolt in expensive injection mold

    Thanks for all the suggestions, I just called him and he want's me to contact Porschefix or Gordon Eng. to get it fixed. We did use a reverse drill ( I happened to have one that came with a right hand cheap Chinese cheesy set) last time I just touched the top of the bolt and it came spinning...

    Thank's for the link I was about to post I will be searching for the bearing post. I adjusted the nut so that when pulling or pushing with moderate pressure on the chuck there is about .001 movement maximum in either direction. Without an indicator I can't see if there is any play at all and...

    SB9 with .009 play along axes do I shim?

    I noticed the chuck and spindle have .009 tho of play along the axes of the spindle. I don't think it was this bad a year ago. I see there is a clamp on the gear side of the spindle and I can see the play right there. Should I put a shim between the washer and the clamp nut or do i do something...
