Reply:Originally Posted by BruceTS99% of the time the guide rollers need adjusting to make it cut straight, but I've seen a few that no matter how you adjusted it, it would still wander, replace the blade with a good quality one and problem sloved.
Reply:Here's my recommendations:Check your guides.Make sure you have a good high quality bi-metal blade.Check your blade tension.Check the square of the blade to your clamping surface.Finally, check to see if the whole saw moves square when lowered (if it doesn't, it may mean that your pivot is worn and needs to be replaced/fixed/etc...--Wintermute"No man's knowledge here can go beyond his experience." - John Lockewww.improvised-engineering.comManufacturer Agnostic:Blood----------Sweat---------Tears----|------------------|----------------|----Lincoln Red, Miller Blue, Esab Yellow
