I have a Delta hybrid TS and am trying to get by with a shop-vac for dust collection. Not ideal, I know, but space is tight and I am not sawing huge volumes of wood. When I run the vacuum, I don't feel much air drawn though the throatplate as there are many openings in the saw. The largest is at the top of the hinged cover on the cabinet near the motor. Would partially covering that opening cause problems such as overheating the motor?
Even though I don't feel much air coming through the throatplate, dust collection is surprisingly good as is. I have some dado cuts coming up and suspect controlling airflow will reduce the mess.
