flat belt pulley pattern

[oldgoaly]

a bunch of ways of pouring it, but when your are close to the limit of the batch, the part as the gating is the most efficient use, center pour 6-8 small risers on the outer hub? would be nice to see how the oldtimer's did it. hmmm wonder if there isn't some sketches in some of the old foundry books??? If I wasn't playing with drill bits and derusting /priming /painting, ahhh the smells of molasses fermenting / chelating, oxalic acid, phosphoric acid. Not to mention purple cleaners and primer smells. all smell better than the dead mouse hiding somewhere in my welding area!
