Saw dust and chips often prevented complete closing of the cheap plastic blast gates I bought so I modified them. The two halves are induction welded and easy to get apart with a sharp putty knife. Drive it in from the same direction as the gate with light hammer taps to cut the welds.
Using your router fence and a 1/4” straight bit, drop one half over the bit and mill a slot through the plastic body – seen on the right side of photo one. Then just drill some holes for number 8 hardware or pop rivet the two halves back together. Now when you close the gate, it pushes the debris out the slot. The second photo has masking tape on the leading edge of the gate and the third photo shows how, when closed, the tape is visible through the slot.
I’ve been using these for about six months with no problems – EXCEPT for the one I stupidly installed with the slot pointing upward! Easily fixed and works great now.
