Has anyone here had good results when using JB Weld to fill in holes in hardened steel? I would need to fill in some 1/8" x 3/4" pin slots on a gun barrel, only to go back and re-drill the same area but at a slightly different angle.
One of my concerns is shrinkage, although JB Weld's website says there is 0.0% shrinkage. Additionally, this area of the barrel will get quite hot, although not anywhere close to the 500*F rating of JB Weld.
I am worried that re-drilling may cause the JB Weld filler to crack.
