Paul,

I'm wondering how your foundry plans on fixing the plate to the aluminium - do they plan to weld
on steel connecting "links" of some sort and could this be a weak link.

The reason I ask is that I assume for wheels the steel insert in encased in the aluminium, whereas
what we need is an external plate.

On the plate issue how would Nitrited mild steel stand-up to the wear.

Spot welding on a few small splayed channels is being considered. Mazda hot rolls grooves
in the steel rotor housing liner which are then rolled over to form tiny hooks. 
We could do that if production volume warranted.
