This is going to be one great performer with
a 300 pound 250 HP P-port Mazda rotary turning
a six foot prop. Lots of room in the cowl for
the cooling system.

The dimensions shown are all you need if you have Jeff's plate
and a motor mount jig.

I am thinking of welding up a tower for sale that can be used
to hold Jeff's plate in position if you want to build
your own jig out of plywood. This could save you
some time. All you will need to do is set the tower
to the proper height and locate the fire wall hard points
on the plywood. When you are done with the tower
you can sell it to someone else. What does everybody think
about this idea?

Paul,

Thank You.

A few questions:

1. Tubing:  I'm planning on using 3/4" x 0.049" wall for all tubes. Is that acceptable?

2. Support mount... what is the size of the short tube?

3. Support mount lip to bottom of Jeff's mount... how much space between the two?

The two lower diagonal tubes, one on each side, should be one inch OD .049 wall.
They are critical for buckling. The X under the engine can be 1/2 inch
which will save a bit of weight. You can make them out of 3/4 if you
wish. The rubber bushings are

I was thinking of making the jig support mount out of 2 inch
OD .065 wall and 1 7/8 OD for the sliding inner tube.
Telescopic in other words. 3 inch angle iron
on top for bolting on Jeff's plate.

Just put the Barry rubber bushings in there for tack welding
and take them out for finish welding. That will locate the welding
cups in the proper place. I should have welding cups ready for shipping
next week. They will cost about $20 each.
