You can always go back to the fellow who started this, Phil Thien.I’m a little confused as to what the width of the slot is. I saw a video where the guy said he read it was supposed to be 1 ¼”, but yours looks wider. Does it matter?
"The bottom view of the baffle. The baffle is cut such that its large diameter is the same as the inner diameter of the can measured at approx. 3" down from the rim. 120-degrees of the baffle is left at this larger diameter, while 240-degrees of the baffle is reduced in diameter by 2.25" (forming a 1.125" "drop slot"
My slot may have been 1 1/4 - 1 1/2in. I recall I was constrained by the piece of plywood I was using. It was not big enough to get to the slot size Phil Thien used.
I think if the slot is too large, more of the debris will escape up into the cannister. If the slot is too small, it will get choked and not allow the debris to fall into the bottom bag.
