Just today I had the need to cut two circles. The smallest is 1 5/8" (13/16" radius) diameter, The second one about as wide as the widest scrap piece of oak. The second one worked out to be about 5 1/2" in diam.
I set the circle cutter up for the smallest circle and tried using a 1/16" blade. The blade cut to the left (outside of the circle) and I didn't complete the circle. Switched to a 1/4" blade and the same result. Even started to burn the edges of the circle. Next switched to another 1/4" blade and had beautiful result!!!!!
LESSON: A true circle can only be sawn with a sharp blade that has teeth with a good pitch (swedge) to the right!!
The larger circle came out also beautifully smooth and round. Both completed circles needed no sanding of the edges to smooth down an offset.
