For those that don't use a air deflector shield on you PC router. You might try a Mega Block Dale Earnhardt Jr. version.
Visit your favorite toy store and pickup a model as shown and with a few modifications, you will not be "blowing so much dust" around all the time...
You will then ask yourself WHY the HECK it has taken you a few years to make this modification. I first tried the double sided tape to hold it on the router but then changed to the lightweight chain version.
The decimal point seems to be the most important on the z axis... x & y not so much.... ShopBot... Where even the scraps and things you mess up and throw away are cool....
