I heard of a guy who will die cast spacers for me of any size I ask him to...
so my next plan of action was to go to that guy
and finally i found that shop of die casting (dhalayi)
I asked him to make 1/2 inch thick (12.7 mm) he told me to go to Lathe Machine guy and that guy told me to get a die casting of about 20 mm thick and 6.5 inch diameter
and the die casting process started ......
