I almost hate to mention this but I was cleaning my shop with my dust collector and cyclone only to notice I sucked up a dust bag that was laying next to miter saw. How embarrassing could that be. Come on admit you have one better than this. We all do stupid once in life time.
Mine is the always never ending clutter.. Some day I hope I can get 'myself' organized..
I have vacuumed up the remote for the vacuum machine also, and had to dig through the bag (outside the shop) to find it but I think the worst I've done ( at least lately) is I actually bent, really, really bent, (did I say bent-twisted?) a 10 inch miter saw blade when I pulled it down too fast on a piece of IPE. It almost wrecked the saw and the back-fence...the IPE got imbedded in the twisted blade, I had to hammer it out.
Well, one day I was cutting some simple rabbets on my table saw and being amused by the 1/8 inch square strips of wood that went shooting off away from the saw. I was safely out of the way of course so It was good fun. Later that day, long after I had completed the task at hand I noticed something quite interesting. Sticking out of my dust collection hose were several thin pieces of wood. After carefully checking the angles I noticed that the hose was in the direct line of fire of my table saw. Oops.
The first time I used Gorilla Glue. I was working on a project similar to a mail room box with many 2"x4" cubby holes. I worked for more than a few hours cutting small dividers and had everything ready to glue up before lunch. So I glued it all up with this new glue I picked up at Lowe's - more is always better, right? Went to lunch and when I got back the Gorilla Glue had expanded and foamed so much the project was pretty much unrecognizable. Had to scrap it and start all over - this time with white glue. I've since learned how to use Gorilla glue and I have a deep respect for its ability to expand and foam up.
