Paul:
I just wanted to throw this idea at you and the rest of the group. Have you seen the large finned thick extruded aluminum
oil/water/transmission coolers that are about 1"- 3" OD, different lengths 8" - 18" for hot rods. How about making the motor
mount out of this stuff. That way, it servers two purposes, motor mount and oil cooler.

I don't know what the strength is of this stuff versus 4130 steel tubing.
But I would think using the 2"-3" plus stuff would be strong enough.

I would not build an aluminum motor mount. the only think worse
than an in-flight fire is if your engine falls off. In a tractor
that is a sure death sentence.
