Looking fantastic Vic!!

Greg's trick to get total adhesion to the alloy rim/parts is to spread a thin layer of slow setting epoxy over the already sanded alloy parts, then sand it all over again with 40 grit, while it's still wet, to get a wet "grey slurry" happening as you assemble.
This prevents the alloy from oxidising (as it will in minutes) as there is then absolutely no exposure to the atmosphere.
