I am finishing the engine mount for my Acrosport-II. I used a Dynafocal ring from Aircraft Spruce. Engine is a somewhat modified Lycoming IO-360B.
The plans show 8 gussets from the tubes to the ring cups. I cannot see how to fit these without forming the rings into tube-sections to match the cups. It seems that this would remove most any engineering strength usually associated with a gusset. Pictures of similar mounts for RVs and Pitts found on the web show similar mounts with no gussets.
So what am I missing?
Did I miss something setting up the mount?
Is there engineering data that supports gussets of some sort or alternatively leaving them out?
What are the consequences if they are omitted?
How do I fit them as functional gussets between the tubes and cups?
What have others here done?
Thanks,
