Please don't laugh too hard when you see the pictures, it's just a proof of concept :o
I'm in the process of redoing my shop and today while I was figuring out how to layout pipe for my new dust collector, which I hopefully will install soon, it struck me that it would be nice to have dust collection built into the blade guard on my saw.
I have a PM2000 saw and I do like the blade guard on it, you can leave it on for just about anything that is a through cut and it really doesn't get in the way. So, although I could go with one the replacement blade guards that has dust collection, I don't have any issues with it other than that.
The guard has a little window (about 7" by 3/4") on the top, which I guess is to be able to line up cuts with the guard in place, however I rarely do that (if I don't really care, I just use the measurement on the fence, if I do really care, I get the guard out of the way to see where the blade will really cut - window isn't generally that clean).
So I figured, hmmm, I wonder if I could hook up to where that window is and suck dust from there. Interestingly if you take a 4" duct and squeeze it down to 3/4", it's almost exactly the length of that opening, but I couldn't figure out how to attach that.
So I made what you see here (assuming I can figure out how to post a picture). The "riser" is the height it is so that the sides of the guard can still go high enough to clear the fence (which I find very useful). The transition from the riser to the 4" pipe is a little abrupt, but like I said, this is just an idea.
So, does it work? It actually seems to. I did a couple test cuts with the (old) DC hooked up just to this (not also to the port on the saw) and there wasn't any dust on the table after the cut.
So, I guess I posting this to see if anyone has done something similar, or maybe just to get a few laughs
