Jarrett and Bill,
       Here is the source of my "Dynafocal" mount info...............

Bill,
       My info says the Type 2 ,18 degree was introduced when O-320's were put in twin Comanches
with extra long constant speed prop extensions (for a more streamlined cowl)............This then put
the engine CG further forward so to keep the Dynafocal mount "Focal" point slightly ahead of the
engine CG the Dynafocal mount angle was reduced from 30 degrees to 18 degrees.........
 
      The Dynafocal type 1 focal point is 14.323 inches from the mounts..................The "Mistral" 13B
engine CG is 9.44 inches from the mount so should work well with the type 1, 30 degree Dynafocal
mount..............IMHO

There is also a Type 2 Dynafocal that I think is in more common usage.  If I recall the angle on it is 17 degrees.

The scanning should give in the tens of thousands [0.01"] or less depending on what type of equipement used etc.   That in conjunction w/ bolt hold placement that I already have [lots of collected data over the years] I should be able to duplicate the basic geometry. From there it will become a new product in that we want to make it something that works for everyone [or as many as possible] to make it a viable unit. That info, mixed w/ knowing what the 'Standard' mount geometry is should get us where we need to go.

Best regards
