DIY Dust Collector System with Homemade Blast Gates and Automatic Start, Stop Function

Continuing off with my DIY dust collector cyclone system I added all the duct work to hook up dust collection to my tools. I show how I added dust ports to the router table, drill press, table saw and band saw. The drill press dust collection is via a locline system sold by lee valley. I made homemade blast gates from some hardboard and 5, 8 melamine particle board. I used a non contact magnet door alarm system to control a low voltage dc relay to control the motor operation when the blast gates are opened
