    Theres an outfit up in Sequim WA that makes deta plate so I may
 splash in the bay there on my next trip up to the San Juan's and
 check them out.

Ken all we need is a thin cladding of aluminum on say .049 4130 steel sheet.
Just enough aluminum to furnaces braze to a Mazda cast aluminum end housing.

We will surface grind and hone the steel after the clad material is furnaces
brazed to the end housing. Maybe chrome plate it after that.

Jim, can we buy the casting from you without the coatings?

    I would want at least an 1/8 inch to give some room for surfacing
and resurfacing in the future and to give a more rigid plate to deal
with warpage.
  It may be more cost effective to buy a thicker piece they have in
stock and CNC mill it out and if the surface is to soft hard chrome
or cermachrome plate it.
