Well, at least we think it is...
Every Thursday night, there are between 4 and 6 guys who meet in my shop to build various projects, needless to say we make a lot of sawdust.
One of the guys bought a dust collector (identical to mine and one of the other guys) about a year ago. He's not a real big wood dorker he does some, but I run more lumber in an evening than he runs in a month.
Anyway, the primary use for his DC has been to suck dust bunnies out of his truck.
All the guys give him grief about his DC. I've called him on the phone to tell him that I'm emptying mine out, and does he want to come over to see how it's done? He says he has "elves" that empty it for him.
Soooooo... last Monday night (while he was bowling) we let ourselves into his shop, and filled (and I mean filled, both the primary, and the bag) his system up with my saw dust. It took him a week to figure out that he had no suction because the DC was full. Here's the best part, he thinks he made all that dust! He is so proud of it that he had his wife take pix of him emptying it out, and he e-mailed them to us. We are all just playing along.
So now, we are going to fill it up again, asap, only this time we're gonna toss in a patio block with the message, "Sawdust courtesy of your lodge brothers at the Old Hippy Workshop".
Can't wait till he finds that!!!
