I think these separators would make a night and day improvement to any single stage system. The problem I run into is using something like that on the planer or jointer fills it up too quick, then everything starts passing into the bags again.

Keep your eyes peeled for thirty gallon plastic drums, if you have the same problem. A plywood top for the one you guys showed and one would be off and running.

Note mine a few posts back. It has handles and wheels installed, which makes it easy to just pull out back and dump. If you’re not running bags, those things might make it a little easier to deal with emptying loads.
