   First I figures out the reason why the BMP wouldn't work because it
   has to be a JPG at least it worked that way for me.

   Second. The bell housing that I have spent the last week polishing
   isn't going to work.

Tony,
I think I read somewhere that a polished surface will not radiate heat
nearly as well as a rough surface. If I am correct, you may want to keep
the redrive surface unpolished to help reduce internal temps.
Is this theory correct, Paul, or am I blowing smoke?

It is a little controversial I think. Conventional wisdom has it
rough and black.
