I'm talking about the metal ring that holds the plastic bag on the bottom, the cloth bag on the top and the inlet pipe in the middle. Any of the units I've seen come with a blower attached to a rolling stand.
My current system has a garbage bucket for the chip collector and a garbage bucket for the dust collector. This was OK in the past, as I would go quite a while before filling the dust bucket. But with the planer, it seems I filled up both buckets in a single session. I'd like something that's easier to empty and has a visible 'full' indicator. I'm happy with the suction from my little blower, so I'm not looking for a full upgrade.
