Gary Martin is now selling a full line of straightedge castings, 6", 12", 18", 24", 36", and 52". Also triangles and right angle blocks. Prices, weights, and photos are on martinmodel.com under "misc".
I have no affiliation. I just purchased an 18", and a couple of 45-45-90 triangles from him. He sent me these photos to show me his selection. I just received the castings yesterday, they look great, although I haven't started to machine them yet.
Gary has his castings fully annealed. When I spoke with him, he explained that annealing also has the benefit of relieving internal stresses. Are there any heat treatment experts here that can verify that?
