Re: 1962 BSA DBD34 Gold Star restoration (hardware going to the plater!)
hi swan....i don't think most platers tumble it all even though they have several size baskets (screened baskets attached to a motor that turns them in the tank).
long, large,heavy parts are hung individually across a large basket (in case they fall off) so they get good plating coverage....the several shops i have used do both, small nuts, bolts, washers,screws, etc in the baskets, long,large, heavy parts hung individually...
try a wire wheel on larger parts it does a good job and the finer the blast media(use glass for cad,zinc,nickel prep), and the better the cleaning finish the better the plating finish ,(like chrome,nickle etc.)..
