When you use a plasma or lasered piece and it expands much greater than those numbers (mild steel) then your nuts will loosen. Material stability is another one...mild steel will dance under the heat due to the stresses (unless stress relieved) and for that length and thickness of material if it is indeed mild steel it can cause bearing issues. All this considering the machinist hasnt done his math on the material involved. Other considerations would be the flatness of the material. Blanchard grinding give materials a ultra flat surface, better than just a machined surface. The holes should also be VERY close to .500. Hopefully all this is integrated into this item.
Okay, so what is the bottom line?
I am reading conflicting comments.
Do Stud Girdles for the AMC 360 work?
Does this piece from Larry Keoman help or hurt?
