Mark,
If you go back through the archives, you will find a lot of different mount
designs.  I don't even know which might be the most popular.  A lot of
builders, including me, used the bed mount like you see with Jeff's install.
Some use what I think is called a Schertz beam mount where the engine is
mostly supported by a beam across the front and is held stable at the rear.
(talking front and rear of the airplane here )  Ed Anderson mounted his
engine plugs up.

If you decide to go with the bed mount, I think that the Cozy Girrls build
and sell the plate that you would need that goes between the engine and oil
pan.  I personally like this method because it helps to stabilize the engine
itself since it is just a stack of plates held together with 12 bolts.  

If your landing gear does not involve the mount, you just need to get the
alignment correct and weld up a support structure, if it does, you might
find it easier to buy a dynofocal mount and cut off the dynofocal ring and
modify it for the bed mount or the shertz beam mount, or something else

Mistral was going to build the engine to use the dynofocal mount and some
have bought the Mistral front cover which allows this.  I don't think
Mistral is still around and making this cover??

But this is really a two part decision.  How are you going to attach the
engine to the mount and how are you going to fabricate the mount between the
engine and the plane.

So far I doubt you will find two the same in the ones already done.  :>)

I am approaching the point in my build where an engine mount is needed.
Glasair Super 2 TD.  So I am not concerned with the mount for connecting
landing gear.  Glasair sells 180hp and 200hp lycoming options.  Estimate the
renesis tuned properly to put out at least 200 (well hoping for it anyway)

Should I go with one of the Glasair offered ones? - which one?

Better to fabricate from scratch?

Other option?

Thanks for any input,

Mark McClure
