Micro torque converter to slow router speed

[technomage]

I have seen quite a few posts about cutting metals and certain plastics with wood router spindles. I got to thinking that what might be useful would be a very tiny torque converter like on a car except scaled down. Being a small fry I have no desire to create one from scratch so I went looking and found this

Its used on motorized skateboards. I was wondering if something like this might work to convert the 8000 rpms of a wood router spindle done to something more in line with machining aluminum.
Hope this is the right forum if not let me know and I will repost.
Hope to hear what everybody thinks.

A torque-converter is basically a fluid coupling that absorbs torque until the fluid becomes "hard". As in a car TC, the shape of the vanes, the spacing, the total diameter, allows for tuning a speed range for the motor to operate in efficiently...what's called a stall speed, where the TC absorbs the initial engine RPM's until the stall speed is reached, where full power is passed to the planetary gearsets. Imagine a paddle in water...at some point you have "grab" or "bite" and the leverage of the paddle lets you propel the boat forward. Until that fluid becomes "hard" against the paddle, it just slips and flows around it...just like the vanes in a torque-converter. It's a torque multiplier, not a gearhead. A gearhead would let you gear down the RPM's of your router.
