Paul could you please post the drawing for the oil pan and include the
materials and dimensions?

I'll be using a mount almost identical to the CH-801 you previously
designed. Also same for the S-beam? When fabricating the S-beam what
radius
is desired for the bend please? Does one use a hole saw for the
lightening
holes or a fly cutter? Thanks a bunch. I have an autocad viewer, so
should
be able to view a .dwg or .dxf file.

Here are some old designs but they may need to be adjusted

If I may comment, drill the holes with a hole saw it is much easier.
Drill from one side, flip the beam over and drill  the other side. The
harder part is drilling the S-beam for the bolt bushings.  No room for
error.   When you install the bushings drive them through so that they
are flush on the engine side with about .250 " sticking up on the
other side.  In other words start with bushings that are at least .250
inches too long.  Weld the bottom side of each bushing 360 degrees.
Lastly, trim the excess bushing in the mill so that final stick out is
about .125 inches and the end of the bushing is perfectly flat.  Jerry
