DIY Vacuum Table

[templecorran]

Apart from the obvious choice of using a vacuum cleaner for the motor, what other suggestions can we come up with?

Vacuum cleaner motors have some basic failures when it comes to vac tables: continuous or long time use can cause the motor to burst into smoke because the motor needs airflow to keep cool. A good vac table won't have much airflow.

I was looking at breaking up a vacuum cleaner to get the impeller and also maybe putting a fan on the other endof the shaft for cooling.

I have a spare tumble dryer motor that needs the bearings replaced, I thinks it might be a good choice.

The biggest factor is NOISE. I need a quiet system. Already I have to shut everything down at 9pm to avoid complaints from the neighbours.

As for the spindle: the B&Q 1020W router is too noisy as it is!! :(
I've studied Jeremy's excellent thread on the DC brushless motor DIY spindle and think it'd be a good solution for my too noisy environment.
