On the HF dust collector, the outlet of the impeller housing is about 6x4 inches, then gets choked down to a 5 inch round house. Not a huge choke, but a choke none the less. On an Australian woodwork forum I read about someone that replaced the round hose with a rigid adapter that matched the dimensions of the outlet on the impeller housing.

Has anyone on here tried that, and if so, HOW, and what did you think of the end results?

Can anyone point me to research on the best location for the hose port on a blade guard.? I've seen some placed at the rear of the guard, others focused on the front of the blade. I'm trying to decide which way to go.

Just curious about the beginning and evolution of the tophat design.

I am looking for just a small amount of 6" flex hose to allow raising and lowering the tophat above the can, using it as a straight coupler between sections of hard duct, both on the inlet and outlet.  I really don't want to buy 10 to 25 feet just to get such a small length.  If anyone has any that you would be interested in selling me, please PM me.  Thanks.

I have read that 26 gauge is the minimum to use for ductwork.  Does that apply to fittings as well, elbows, wyes, and laterals, or does their construction make them sturdy enough at 30 gauge?  Has anyone here ever experience a 30 gauge fitting collapsing under vacuum?
