I’ve got a 2,5 HP dust collector with a 5” port. I came with a Y-connector, that is designed to split the 5” inlet into two 4” (i think it’s like the one from Harbor Freight).
Now – i am going to make that into a central system, with metal ducting, and after some experimenting i learned that you ofcourse lose a lot of airflow by reducing the pipe diameter, but also by going up a size, and then reducing down again.
So i elected to buy 5” transparent dust collection hose (damn expensive), thinking that i could always find fittings later. But alas – it’s easy enough to find 5” ducting and bends. But connectors and y-sections and blast gates – not so much. I found one place that would sell one y-connector for $80 which is too rich for me. Seems like the hobbyist standard diameter is 4”, but that reduction costs 30% airflow.
SO – i’ve decided to build my own blast gates, connectors and Y’s from the 12mm phenolic covered plywood that’s sometimes used when casting cement. It’s very slick and very stiff (9-ply hardwood with waterproof glue).
But i would like some ideas and pictures, if anyone has made their own. I found a cool homade blastgate on youtube, but has yet to come up with a slick way of making a quick connect solution for attaching a dust collection hose to different machines, that are not going to get a “hard line”.
The idea of having to make all kinds of insane compund cuts to make everything smooth is kind of frightening :).
