This is the first time I've ever used a circular saw. I'm using a Ryobi 18v to make a cut through about 30 inches of 3/4" pine.
Everything is secured with clamps, and the edge that I am cutting is free to fall off (i.e., I'm not making the cut in the middle of where the wood is supported). Per the instructions, the blade clears the bottom of the piece of wood by about 1/4 inch.
I have tightened the blade securely.
I'm using another piece of wood, clamped to the wood I'm cutting, as a guide for making the line. To the best of my ability to tell, the flat plane rests appropriately on the wood I'm cutting, and I'm going straight forward, not trying to curve or anything.
Basically I get an inch or two in and the blade seizes and stops. I've made it through about six inches and figured it was time for actual guidance.
You may read a brief history of other power-tool based travails of mine here
. The primary cause of that particular problem was that I was overcompensating for what I thought was a lack of strength, and not really having gotten a feel for the tool. That could also be the deal here, but if I should be pulling back (easing up on the trigger/speed?) I can't tell, and the circular saw is scarier than the drill.
Also interested in any other tips on using this tool. I am aware of: don't wear flowy clothes, don't wear gloves, tie back your hair, two hands on the circular saw, wear eye protection, don't be drunk, don't invite pets or small children. (It's taken me about three weeks to work up the nerve just to use the thing.)
