G'day Norm ,Jeff and Mf

As far as I know the barbell weights are made mostly from cast iron, I am also guessing it will be ok but I can't say I
have seen a cast weight welded to a crankshaft nut before ,cast iron is used extensively for flywheels so I can't
see a problem with the weight it's just the welding that needs to hold long term. .
