Just been doing some raised and fielded panels using the trend raised panel cutter (big cutter) In the Xtreme Xtension In a Default 625 . I have the speed on the lowest setting and the XX is balanced nicely . Ive done this lots of times before but this time the collet keeps working itself loose . Lucky i heard the cutter starting to take deeper cuts and stopped the router before the whole assembly came out . I rebalanced the XX and started again , and again the XX started to work loose from the collet . I checked the balance was ok and managed to get two half turns on the collet to retighten it :shock: Im at a loss as to why its started to happen half way through 16 raised panels . The only thing i can think of is taking to much timber off in one go but there is no labouring of the router and the oak (had to be oak thats getting ruined didn't it :evil: ) is passing through with little or no effort . Any ideas please ?????? :?
