Well after two and a half years of using this adapter, it is still working well. There is still some saw dust that ends up on the top of my mobile cart, but the fine airborne dust ends up being sucked into the dust collector.
Yesterday, I was cross cutting for a couple of hours with my miter saw and my Dylos meter kept below 300 particles the whole time. (300 is a great reading. When I take my Dylos outside, it can hit 1000 easily on a dry summer day.)
I found that wider boards will generate more airborne dust, due to the blade being further from the dust port. Narrower boards, don't create as much airborne dust particles.
Overall, the adapter was worth the time and energy to build.
Ain't technology grand........when it works.
