Stuck setscrew update..
A couple of days ago a guy from the local sawmill
stopped in for advice on how to remove a stuck setscrew in a log de-barker head. It was about 3/4 below flush, 3/8 thread. I gave him a 3/16 drill welded to an extension and told him to turn it as slow as possible with heavy pressure. The hex was stripped out bad. The bits he had would not touch it. He came by today and said he got it out and didn't break the drill but he used a hammer drill to turn it! The drill went through the screw with no arguing at all! He was a happy camper.. ;)} Thought you guys would like to hear this.... I never thought of using a hammer drill for this.... phil k. |

I would have guessed that you might use an impact driver, drill a pilot hole, then weld an ez out to the socket on the impact driver, and maybe that would do it. Anyway, was it it the percussion that did the trick? Steve |

Apparently the percussion effect was the trick! Had I seen the guy pick up the hammer drill I would have been shocked! So it's true, you learn something new every day, eih? phil k. |

I've been able to remove rusted bolts or nuts with impact
wrench. I'd not have thought of using a hammer drill for a stuck setscrew. Great idea, thank you. Oh, uh, er, thank your friend who had the idea. You learn something new every day, if you're paying attention and humble enough to be teachable. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Phil Kangas" wrote in message ...
