Hi Joe
Just my 2 cents.
Bob, just lately has been a bit more conscious about the saw dust because of Rick I think ,he is now using a vac.system more and more to get the chips from the router when they come off, Bob is the old Pro. and is was set in is way, he would just brush them off and out of his way just like, he also just drops the wrenches down in the hole under the router and it works for him and Rick, he can always find them in the saw dust under the router just where he left them.
No strainer that I know about just some saw dust down below.
But you will need to get it from Bob & Rick
to be sure on this one, if you are lucky Rick will see your post and come back to you...
with some info.
