Jerry,

I had this idea quite some time ago but have not had
time to knock it out in Rhino. I think you
will find this much easier to fab than my original idea
of the aluminum spacers and rolled 3/16 sheet aluminum
tig welded to the spacers. You can weld this up anyway
you wish. It uses 1/2" 4130 .035 wall tubing bent using
a plywood form. The radius is about 7 inches. Heat the tubing,
clamp one end and pull it around the plywood form.
Not all diagonals will be needed to be bent to clear the
starter ring gear.

I have never been entirely comfortable with the aluminum
block configuration for several reasons. High weight among
them. I like this idea a lot better.

Paul,
What is the length of the horizontal pieces of tube(i.e. distance between
motor and plate)
Thanks
George (down under)

As I recall it is 3.050 inches.
