I've attached photos of my mount mockup.  I intend to build it with .75" x
.049" wall 4130 tube.  The vibration isolator support tubes will be 1.25" x
.065" with a .125" x 2" diameter washer welded to the end.  The aluminum
bars bolted to the oil pan are fabbed from 1/2" 6061.  The Barry mounts are
PN 26834-1 (6309K-36 McMaster Carr) 380# axial, 165# radial load.

Question:  The aluminum mount bar nearest the table has only one 6mm cap
screw on each side turned into the cast iron end housing.  The rest turn
into the cast aluminum cover.  Is this strong enough?

Your comments and suggestions are welcome.

Looks good Gaylen. The answer to your question is yes. The rear part
of the mount has little or no load as the front of the mounts
are near the horizontal position CG of the engine/redrive/prop 
combination.

Your Barry mount choice is good too.
