foundry work - aluminum pulley

[celsoari]

Is it stronger to case the block vs using a round extrusion that is the same diameter? I am a novice and have no idea, I can get just about any shape in any size I want at a local store, cusious why the choice is to cast the block vs cust it off the end of a round bar? Your work is beautiful, at times I really want to learn to cast as well as you! -jeff

I chose to cast, as the store is very far from my home. Thanks for commenting
