I needed a way to make a simple quick hose disconnect for various tools.
since I am using 5 inch pipe with my Supper Dust Deputy and then short 5 inch hose I took two toilet flanges sanded them flat then drilled with a forestner bit a flat hole 1/2 dia. Supper glued neodymium disc magnets into the flat face of the flange. I do this on two flanges and pay particular antention to the plolarity of the magnet so they attract each other. I used 4 magnets on each flange mine are .472 dia X .118 inch thick.
I leak checked the flanges with the DC on and using incense sticks to see if the smoke is drawn in to flange connection.
To flatten the face of the flanges I taped with double stick tape to a flat surface (Glass) 180 grit sand paper.
With the 180 grit I removed the lettering on the face of the flanges, then moved to 220 paper to remove the sanding marks. Prior drilling and mounting the magnets.
The Flanges I bought at Lowe’s is a Oatly 4 inch flanges ID is 4.0 inches OD is 4.5 inches.
The smaller ID does cut down on the CFM from the original 5 inch hose however I have plenty of air flow to move the chips and saw dust.
