On my BS this would be good as I do cut aluminum from time to time and I am finding it being pressed into the bottom wheel rubber, this can not be good! So with the cross suction at the bottom of the table I would catch most of this and what is missed would hopefully now miss the wheel as it is suck to the right.
The question here is if I leave in the bottom port with suck would this interfere with the cross flow by pulling some air down??? If I leave the bottom port open it would have air coming up as well as the cross flow to a lesser degree??? And if I just seal the bottom port up it will slowly fill up!!!!
May need to put a 45 degree baffle just below the new side port with a slot for the blade to help direct the air and put a opening the bottom door for the bottom port to feed from?? What do you think?
