I'm about to start the build of a 2x3 cnc router based on the FLA/CNCRouterParts design. see:
http://www.cncrouterparts.com/index.php or
http://www.finelineautomation.com/
or their threads in this forum.
I'm planning to use a Bosch Colt PR20EVSK-RT router as the cutter.
I don't have one handy, but I do have an old Rockwell 4620 Router.
It's noisy. My Radio Shack sound level meter reads 90-95db at 3ft
when running (no cutter, just running the router).
If I leave the router running in my basement I get readings of 60-65db
in the room above the router or outside the basement window
[poured concrete foundation, the noise is coming thru the cheap
basement window].
That's way too much noise to expect my SO to tolerate. I also don't
want to risk annoying the neighbors with the noise either.
I'm planning on putting the router in a (roughly) 3x4x3 box made out of
1/2 inch MDF. I might line the box with homasote for additional noise
deadening. I'll need to provide ventilation, but I'm planning on a dust
collection system anyway. That should suck in enough cool air to keep
the router cool.
has anyone built a similar enclosure or tackled the problem in a different way?

ps: yes. I also plan on blocking the window well with a sound absorbent
panel and might cover the ceiling with homasote to kill some of the
sound transfer to the upstairs rooms.
