 Ken, I understand the desire for a thicker steel plate to

allow a

 "fudge factor" when machining. But the chrome plating

mystifies

 me. Why not nitride the surface as is done on the standard

Mazda

 plates? This is a simple reliable treatment, that is a

molecular level

 physical change and doesn't flake off like most chrome

treatments can.

   I think that the nitride process would create too much heat and

warpage and may delaminate the bond between the plates.
