Hi all, new to this place, I felt inspired to join up because I've recently acquired a nice Bosch GOF 1600 CE router and bought the fixed base
for this router from Amazon.
The fixed base I installed into my homebrew router table.
Currently I am building a new kitchen and I'm using Blum hardware that requires me to rout a 38mmx8mm rebate (rabbet I think in American?)
into the drawer bottoms.
Put an 18mm router bit with a 1/2" shaft into the fixed router base that's sitting in the table. Started making some cuts, around 16mm wide by
8mm deep. It worked fine for a while, when, suddenly, the router bit emerged from the top surface of the work!
Imagine my surprise. Just glad I didn't have my hand anywhere near.
This is not the first time it's behaved like that. The first time it happened I assumed I might not have tightened the collet sufficiently. I also
cleaned collet and router bit shaft with acetone, in case of oil or other lubricants. That time I was able to finish the job.
But twice? That is no longer an accident. I checked, the collet was really tightly torqued up.
I'd made about 8 or 9 cuts without a problem, when suddenly the bit started climbing, and it climbed 8mm (3/8") over a stretch of 200mm (8").
It still was as tight as I can get it when I dropped the motor out of the table and checked the collet. But, having said that, I was able to gently
tap the bit back into the motor with a piece of 4x3 that I had lying on the workbench.
I simply don't know what's going on with this. Is it the collet? Is it my technique of using nearly the full width of the router bit (I was cutting with
the end-face of the router, and not with the side, running the sheet of mdf over the table)?
(please don't ask if I was using a 10mm router bit in a 1/2" collet -- I am not THAT clueless
