I've been wanting to try this - unfortunately, most 10" blades are made more for tile saws, and they have a triangular arbor. Probably to ensure that guys like me don't stick them on a big gas saw at 5,400 RPM....
Anyway, as I'm sure you all know, the smaller the diameter of the blade, the tighter the turn you can make when cutting on the paved surface. I think 10" would work best: Radius of 5", take off 2" for the arbor guard and you have 3" left, which will get you through most pavers, from Brussels to econo Hollandstone.
Anyone give it a try before? Are the 10" blades cut out for our brand of punishment?
