Who has made "Gong" or "spinning steel" targets?  What type of steel plate and thickness?  Any tips or tricks to share?  Other ideas I did not mention would be more than welcome as well.

Thanks,

I have made some Gongs out of 3/8" cold roll plate. they held up to about 100 rounds of 556 at 100 yards before they started blowing through.  I have also used 1/2" but that starts to get thin after a few rounds also.  The best stuff is AR(abrasion resistant) 450-500.  It is much more pricey but it will last forever.  I  believe that is what a lot of the retail targets are made of.  How they are mounted makes a difference too, the more movement it has, the less energy the steel has to absorb.
