MDF and alu sandwich router

[michael]

I had one to wire into another machine...I didn't believe it was spinning at 30.000RPM it was so quiet!...applied tacho....30.100RPM Are you considering water-cooling the router mounting?

I did notice the 43mm collar felt rather hot after a short period of time, Is it the bearings that are getting so hot or just the motor it self.

Water cooling the mounting? Sounds interesting have you any examples on how this can be acheived:question:
