Not sure it has been posted here, ut, when changing the plastic bag on my dust collector, it usually took about 5 hands to get it done, after about 7.5 tries...

Next time you want to do it, get some 1/2" rare earth magnets and start on the back side (of the bag) just above the clamp track. Then work around, folding as required, and adding additional magnets in a few places to hold it in place.

Then EASILY put the clamp around and fasten it in the track. Remove magnets until next time. Made it MUCH EASIER to get the job done.

Hope I didn't duplicate anybody on this, big thread to check!
