Use Router after bit damage?
A bit worked loose out of my 1/4" router as it was going. Fortunately it
didn't fly out, but it did tear up the wood quite a bit. Now I've clean up the router however I question the safetyness of it. Although bits fit in the collet and seem to tighten securly is the router safe to use after this mishap. I can see events where the bit seems secure and goes flying out again, this time with very dramatic results and a trip to the emergency room. So can I use it safely or should I pitch it? TIA Just call me 'shorty'. |

Use Router after bit damage?
Clean the shank and the collet thoroughly with acetone or alcohol.
Insert it just about completely into the collet, and check it a lot whilst using, Shorty. Tom |

Tom Gee, I've never been able to focus too well on a bit turning 18,000 RPM. I can't even keep my eyes focused on our ceiling fans, when they are on "high". dave |

TIA Just call me 'shorty'. I had that happen and sold it on ebay. I am pretty sure I put it in properly, so if it happened once it can happen again. I wasn't so much worried about it flying out, as ruining another project. It happened to be a craftsman that is notorious for the problem; yours might not be. |

TIA Just call me 'shorty'. Sears Craftsman router? This was a common problem with those. I did get a lot of use out of my 1/4" Craftsman router even though it did exhibit this automatic adjustment feature, but I also finally replaced the router because of it. You can minimize how often this occurs by keeping the collet clean, clean the shanks of your bits with alcohol before using them the first time, and by running a fine sandpaper around the shank from time to time. The sandpaper will roughen up the shank surface a bit and give it some tooth. That will help the otherwise weak collet design hold the bit more securely. You don't need to make the shank look like a hole rasp - just a slight abrasion is enough. Beyond that - my only recommendation is to double check the bit height often during the time you're using the router, and don't push it too hard. I found that the harder I pushed the router, the more likely I was to suffer this automatic adjustment feature. -- -Mike- |

TIA Just call me 'shorty'. Are you using a craftsman router by chance? They have had a lot of these types of problems. Search the archives http://groups.google.com/groups?hl=e...ec.woodworking using 'automatic random height adjustment' and you will get the idea. Frank |

Down shear bits can be pulled down if you take too big a bite. Especially if it is a hard wood. -- dadiOH ____________________________ dadiOH's dandies v3.06... ....a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.

Use Router after bit damage?
I make a motion that 6mm shank router bits be marked clearly and
disposed of in shops where there are only 1/4 and 1/2" router chucks. I have disposed of a few flea market bits and sets after getting home and having one escape my P.C. 690 VS. I thought it was my fault, maybe not tight enough. Then I tried to re-install the bit,after tightening, I could turn the bit with my bare hand while holding the collet with a wrench! I checked all of my bits with a drill gauge and threw away anything that didn't show a full 1/4". 3 or 4 bits did not measure up. Be careful out there, Tom |

The front edge has a thick maple block on the underside to catch anything that might fly out from that direction. Of course, that protection isn't available if it somehow flys apart and the pieces exit across the top. Again, kevlar apron to the rescue. |
