Harold, Thanks for the response. I would try to machine the bolt without anealing or heat treating. I have used grade 5 and AN bolts in projects, but never tried grade 8 bolts. Will see how it goes. The Mills 1.3 is a diesel model air plane engine. It is one of the projects in the first issue of Mod...

Why not use an iron crucible for alum? Does that apply to a welded steel crucible also? Thanks, Larry
