    Default I learnt something new

    One of my triton routers has the chuck style collets (tra100b I think)

    the other day I made a new cabinet including power switch for the table top I had made previously

    I checked the function of the new power switch by running the router very breifly - without a bit in the 1/2" collet

    after that I used a 1/2 " shank dovetail bit and found it moved upwards in the collet when I used it even after heavy handed tightening

    it turns out I damaged it by running it without a bit, I bought a new one from carbatec today and the damage is very apparent when comparing the two as regards excess play

    I will think twice before doing that again

    just thought I'd mention it as a precaution

    I am always very wary not to run a router without a bit in it. I am always concerned that it will either spin the nut off when slowing down or with the sudden start over tighten and damage the collet which appears to have happened to you. Even though the Triton is a soft start they still start fairly quickly with a jolt at first movement. At least you were able to get a new one locally and didn't have to wait for it to be imported from England like we did when no-one was handling them in Australia.

    thanks Dallas
    not sure if the damage was done by over tightening or just very high rpm's throwing the collet every which way within the nut when I turned it on for no more than 2 sec's, I don't remember it being tight or anything but normal until I used it next

    the actual collet was very loose (sloppy) within the nut, which made me think it was caused by centrifugal force

    the good news as you say is that carbatec had it in stock and probably have another 15 or so in stock in case I have another moment lol
    I've made it a rule now to remove the collet with the bit everytime

    Turning the router on without a bit will have allowed the collet to come unseated if you didn't notice this when putting your dovetail bit in, then because the collect was unseated it wouldn't tighten correctly and grip the bit.
