I'm planning on building an inexpensive saw for slabs and thundereggs. I'm hoping to mostly use parts I have in my garage. I've got several 1725 rpm motors. I have a half inch shaft, pillow blocks, half inch arbors, and several different sized pullys. For the tank, I'm thinking about using an old free standing garage sink that I'll build a cover for. Planning on using gravity feed on a swing arm. I'll likely have the swing arm pivoting on threaded rod to adjust the thickness of cut.
My question is what size blade can I comfortably use with this set up? It looks like most blades with a half inch arbor go up to 10-12 inches. I know I can get shims to go larger but would a half inch shaft be strong enough for a larger blade? Also, I have a 2 inch flange. Is that large enough for a saw blade? If so, how large a blade would that accommodate?
I don't need a monster saw but I figure I may as well get the most out of the parts that I have. Are there any inexpensive parts I could change to get more bang for my buck?

There is a formula for determining the size of the flange washer relative to the saw blade diameter. Having an adequate sized washer will reduce chances of dishing or flexing the blade. Someone will tell us what the relative relationship is.
