So where were you with your good ideas a year ago???  ;-)  Actually, I
was able to do something very similar by using 2x4 blocks and resting
the engine on the factory bed mount.  Your approach sounds like a good
idea for someone that is building a motor mount from scratch.  I also
like the approach of tipping the engine vertical and using a dummy
firewall. =20

Thanks for sharing your ideas, even if it is a year late.  Maybe someone
else can benefit from your suggestion.

I found a really easy way to do this using a laser level and a homemade=20
stand.

The stand can be thrown together in a few minutes from some 2x4s and=20
assorted scrap wood. The top 'box' should fit the sides of the oil pan=20
closely.  Drill 4 holes around the top so that a 5/16 bolt will drop=20
in.  Put a nut on the bolt, then a washer and set one in each hole.  The

bolts should rest just inside the oilpan flange.

Set the airplane up so that the level shines through the horizontal=20
centerline.  Now move the stand in front of the airplane, and set the=20
engine on it.  Adjust the nuts on the bolts to dial in the height,=20
upthrust, and make it level.=20

Now move the level to indicate the vertical centerline.  Slide the stand

left or right, or turn it, to center it and get the correct left or=20
right thrust.  Taps from a small hammer at the very bottom of the legs=20
will let you move the stand in very small increments.

The second adjustment will most likely disturb the first, so iterate=20
through both adjustments until nothing more needs to be done.  Now weld=20
the motor mount together in place.
