Hi paul,
Some questions on the alloy end plates.
 From earlier posting's there was discussion on using aluminium end plates.
Was there not a wear problem with these and many suggestions to use
ceramic coating.
End plate supplied by Racing Beat, what grade of alloy is used. Are they
cast or machined from plate or billet.
Regards Don

Coatings of almost all kinds are very problematic and that is why I suggest the 
detonation gun method. If fires carbide particles at the aluminum at supersonic 
speed and they mechanically embed them selves in the aluminum surface.

That is the main reason for the two piece end housings. The wear surface can
be 4130 steel sheet, hardened and ground. Even nitrided for super hard
and super low wear.

I don't know what alloy Jim at RB is using and he won't tell me what kind of
coating he is using.
