[Above] Behold a common jigsaw. This is actually MY jigsaw. I have 3, but one was my Dad’s, one I got from a friend. None of them are the good kind with a bearing supporting the back of the blade, but that’s OK. It works. I sometimes grab it for down and dirty work. What annoyed me was the way the sawdust would always obscure any line I was trying to follow. This meant that I’d have to play the Big Bad Wolf and keep blowing the dust away from the blade. Then I got an idea…
[Above] The motors on these saws blow air out as they run to help cool the motor. The area circled in red is only a small portion of the air outlet vent which is actually on both sides of the saw. I thought that if I could direct a little of that expelled air in the right direction, the saw would blow its own dust away.
[Three Photos Below] I took a piece of copper tubing, bent it a bit and shaped one end as best I could to fit on the saw to divert a little of the air flow. This could perhaps also be done with plastic tubing, but I didn’t have anything appropriate aside from copper tubing. It’s the bendable kind, not rigid pipe.
[Three Photos Below] I attached the copper tube with hot melt glue as shown. Before attaching it, I cleaned the area with rubbing alcohol (It was handy). You can use the poison of your choice.
