I just got my first circular saw a week or two ago and used it to cut up some plywood from my floor. It seemed to cut alright at first, and then I went through a double layer of vinyl a few times, maybe 10 feet total and it seemed like there was something melted on the blade. Just a slight residue, but it seemed to get harder to cut. And then, it started to burn the edges of the wood. I quit using it on the plywood and cleaned the blade with some organic solvent. I then tried cutting some stud-grade 2x4's and the blade spins fine on its own, but once it gets into the wood, it stops turning. The blade edges still seem sharp, but it basically cuts nothing now. It's a 12hp Skil saw with a standard 40 tooth blade. Should I just replace the blade and try again, or could it be something wrong with the saw? thanks from a newbie, m

Has anyone found a better system than ladders to get to high places. Seems to me a one man lift of some kind would be better than ladders and jacks w/planks or quicker than building scaffolding. Anything on the market for homeowner use?
