Cutting question

[edward]

I been cutting 1/2" oak with a #3and #5 blade and the front looks straight and when you look at it from the back it looks beveled. the table and blades are level and tension is good, any suggestions what cause this the blades are FD. just curious

[fredfret]

90 deg exactly for blade to table or side pressure nost likely. Excess front to back blade aggressiveness can also cause it.

I agree with Fred. If the saw and blade are square (90 degrees) then you are pushing vs straight feeding more then you think.

Agree with above. As a way of proving things take a block of wood about 1" thick or better and just make a line up and down. Make sure it is 90 degrees to edge of wood so use a square. Now cut on that line. If the cut is straight and blades are true then it should cut straight. To prove this take that block of wood and now try to insert the blade from the back side. It should slide right in with no deflection. You can also lay a square along side your blade and operate by hand the motion of the saw and watch the blade against the square. It should travel straight up and down. If not you need to look at table to blade and also the setscrews being equal in your clamps. Not much more to it. If all is good then you are pushing to hard and not allowing the blade to cut. I use a #5 FD blade for just about all my cuts. It is a nice middle of the pack size blade.
