Do you guys have a single source where you get all your hardware? I'm tired of buying a couple of things from StewMac, a couple from allparts, some from Warmoth, etc.... The shipping costs are adding up! Also where can I get some large nut blanks? They seem to be very hard to find. I just ordered some from allparts but their selection is limited. I want some 1/4" thick and at least 1 7/8" wide.
