Maybe you guys know a better way.... when I am routing binding channels, as the routing progresses my router bit seems to slowly come off the collar and causing the channel to get deeper. I tried tighter but the same happens... I'm sure there is a better way rather than adjusting the bit every 30 seconds....

Where's the edit button?? What I was trying to say is that the bit slowly slips out of the collet....

The router bit must not be inserted all the way into the collet before tightening. It should be approx. 1/8" from "bottoming out". If it is "bottomed out", the collet can't tighten properly. Ray |

Peter, I'd check the inside of your collet for some sawdust that may have pressed against the inner wall first. Clean with WD-40 on a Q-tip, then alcohol. Also, the tool bit you are using, be sure it doesn't have a build-up of wood resin. can sometimes cause the bit to have some vibration. Maybe you have thought of this but it's all I could think of.

other problems which can prevent correct tightening of the collet can include debris in the collet or its recess, sap residue on the shank or in the collet, dings in the collet or the shank, etc. what sort of trimmer is it? you really need to determine the cause and correct it as this is a potentially dangerous situation both to your work and to yourself. a bit coming out at 20000++ rpm is a potentially lethal missile. |

Peter I use an o-ring that fits snugly in the collet, push it in until it bottoms out and lesve it in there,it keeps the bit from bottoming out and not locking up tight. It works for me. |

hesh, the 310 is notorious for the problem when new. a firm rap or two on the collet nut with the collet wrench usually releases it without removing the nut. they tend to loosen up with age. p.s. one wonders why they haven't fixed such a minor niggly problem after the machine has been in production for so very long. |

Another trick is to place a piece of wood on the bottom of the bit and give it a quick rap with a wrench. It pushes the shank back up the collet and release the shank. Peter |
