     Don't know Russell. We should contact:

Paul, If you bond the materials at a higher temperature
you will have built in stress at low temperature.I am not
sure of the ability to preform the explosive bonding
at elevated temperature. The real question here is would it
help to keep the sideplates flatter at operating temperature?
Or to put it simpler, would it be worth doing if you could? If
you used a good quality milder carbon steel and nitrided it,
the mechanical ground should be the housing. Then the
surface should be controlled by the housing, so heating
shouldn't be needed. My best WAG.

I don't think it is possible to use the housing directly. I think we
need to bond to sheet aluminum and furnace braze that to the housing.
