I'm with bigmike...there's only so many blocks, so don't be too quick to junk it.
Also remember that JBWeld is an EPOXY and is not metal...it does not have anything close to the mechanical properties of a metal. All those "strong as steel" epoxies are a bunch of BS. The ultimate strength of all of these tops out at about 5000 psi, much lower than, say, hardware-store cold-rolled steel at about 36,000 psi if I remember correctly....
