2 piece EM welding, skimming, and coating

[Stetina]

OK,  I'll do the checks when I get the pieces back from the machinest later
this week.  You're right, I should just change out the mount.  Do you think
the other side (Rad side) should be changed as well ?  Or do they hold up
much better ?
Thanks.
Joel
