I have a 12" sliding miter saw on my bench at my new shop. My old shop, I had a 6 inch pipe from up above to just a square box around the saw.
In my new setup, I am running the 6 inch piping down low under the bench. I am going to cut a hole in the bench behind the saw to run the DC piping up to a vent.
I have a 12x6 Universal register box like picture 1 below sitting in my spare parts.
My question is, should I get a ceiling box like picture number 2 in a larger size like a 12x12 or 12x16 to where it actually goes partially underneath the back of the saw?
My original thoughts are the bigger the hole the more it'll catch falling. My secondary thought is, the bigger the box, the less suction...
