I've check the square of my blade to the table many times and still when I cut circles for the mug or bowls.the top is good but then it angles out word some {it's nut square]. I've tried different speeds and am holding piece as staight to the blade as I can for a circle. Using a fdur-9 blade.
Any help would be appreciated on getting a better cut....Dav

Increase tension on your blade, slow down your speed and cut the outer portion of the circle counter clockwise this will help compensate for blade drift. Try using a #5 or #7 instead of the #9.

Why such a large blade, what kind of wood are you cutting? I would defiantly use a smaller blade and I think you need to increase the tension. Not enough tension will cause the blade to bow slightly. 8)

I cut walnut,maple,purple heart plus pine on a bowl

Dav there are several things that will cause this to happen. The most common is the tension is too loose. The next most common is that you are push the piece to one side slightly this causes the blade to have a side force which will cause it to have a bow shaped cut. Practice will help a lot with that .... you can really tell the diffrence when you are cutting thick wood 1 in up to 2 inches thick. On the thicker wood slow down your cut and let the blade do most of the work all you need to do is guide it.

Tighten your blade a little more. I cut everything on slow. I guess I'm not in any big hurry. Also I cut counter-clockwise. Dave 8)
