Fairly new to woodworking here. I bought a dirt cheap 13 amp $40 Ryobi from Home Depot, and I've used it for certain things successfully, like cutting 4x8 1/2" plywood pretty straight.
Lately I've been getting some pretty bad blade binding, and seemingly warping and bending as it travels down creating a horrendous, wavy cut.
First happened on some 3/4" melamine. I was able to go back over and fix up the edge.
Happened again today on some simple 1"x4" pine, trying to cut at a 45 through to make a french cleat hanging strip.
And it was apparently bad enough to rub markings off the blade.
So a couple other points to note:
- I had not previously used the blade on each day I made these cuts, so the blade was cold and they were the first cuts of the day.
- The blade on the saw now is the one seen in the photo (looks about 24 tooth), which came with the saw, and has only been used to cut the melamine board in the first photo. I swapped it on when the first blade (about 60-80 tooth) started warping, and I thought maybe the blade was old, and the 24 tooth was the only other one I had.
- Had a straight guide edge in both cases clamped down, and it did not shift whatsoever.
- I did not push particularly aggressively. In fact in both cases, I went back and tried to progress extremely slowly, and it was as if as soon as the blade went into the wood, it just started having major trouble.
Not sure what's going on, but I'm trying to avoid an unsafe condition and get perfectly straight cuts. Any ideas?
