Update: it in fact will cut 3/4" birch plywood. It's not as fast as a circular saw but it's a touch more accurate too! /forums/images/graemlins/grin.gif
Ok.. I used a single bit and made 4 cuts. I bought a pack of them expecting to break the bit at least once.
Something I didn't really like, but I'm 99% sure it's more operator fault than machine... /forums/images/graemlins/crazy.gif
The circle tool for the rotozip is stiff, but plastic. I don't like spending $24 on something that probably has a manufacturing cost of $1.50. In other words, I thought it was/is kinda cheap. It did NOT (as far as I could tell) slip and lose my "angle". I did cut the first circle and cut counterclockwise for about half way, then I went the other direction. Upshot, the line didn't meet. I highly suspect there is SOME flex in the tool that helped (to a minor degree) cause this.
My first (outside) cuts went pretty well. I DID screw up the measurement, so I'm not sure that I understand the scale on the tool... sigh... /forums/images/graemlins/blush.gif I need to measure twice and...well, you get the idea. Lesson learned.
On cutting the INSIDE of the circle out (even though OUTSIDE is too small, I figured I'll do a trial run on this), the circle was rather difficult to handle, so I cut a bit, turned, cut, turned ad nauseum. When the center fell out, I have TONS of little flat spots where I started/stopped, nowwhere as smooth as I was able to get the outside (when it was connected to the larger piece of wood for stability).
Sooooooo, I have this piece out for the wifey to see and get her opinion. If she likes it, I'll measure twice, cut steady, slow and in SAME direction (to keep same "flex" perspective on tool) and give it a whirl.
personally, I think it will work once I get a bit more proficient at it. I just wish I hadn't been so brash & cut 3 pieces out (1 trial & two "real"). I cut the two "real" pieces out so I'd be using the same setting, little did I realize at that point, that the settings were off.
oops

Oh, and another thing I didn't much care for, to initiate the cut, you do a plunge cut. You can not evidently, put the guide into the guide hole and then move on. you have to sort of do both at same time. (at least, I did). I'll work on that again, but this is another area where the (small) flex in tool might rear it's ugly head. I might try the raise/lower deal & plunge that way, although the directions specifically say to plunge it 1/8" OUTSIDE your cut. (how can I do it OUTSIDE my cut, if the cutter only goes "X" distance out?) (answer: bend/flex/inaccuracy??)

It will likely work for my simple needs though, and if it does, that will be the good news.
