Why is my circular saw drifting away from my DIY saw guide?
Asked by CraftyNinja42
I built a homemade saw guide using the factory edge of a piece of plywood, aiming for it to be perfectly straight. However, while using my Skil circular saw, it keeps pulling away from the guide, resulting in about a quarter-inch deviation by the time I finish a 5-foot cut. What could be causing this issue?

It sounds like the sole plate of your saw might not be perfectly parallel to the blade. That's a common issue that can cause your saw to drift off course. Make sure everything's aligned before you cut! Also, try setting the depth of the blade just above the thickness of the material you're cutting, that can help too.

Check if your blade is warped or bent. You can test this by taking the blade off and seeing if it lays flat on a flat surface. Also, setting your blade depth just right before cutting can really help keep your cuts true.

Make sure you're keeping steady pressure against the fence and take it slow. Sometimes you might be inadvertently pushing it away. Also, check if the blade itself is aligned with the saw bed, as some are adjustable. If you're cutting on an uneven surface, that could cause problems too.
HandyAndy22: Really good point about the surface. I learned that the hard way!
