Hi Paul
There is the preliminary design of the prop end as attachement and i  took
your lycoming main bearing idea and i found is the best way to go.
With all the airplanes i builded and flown sice 1966 it  prove you i  am
not wasting your time .
I am learning the IMSI Design cad and i soon i controlled it i  will design
the whole system.
I will be back home in Fla at the end of september.
Paul how we stand with the P Port  job order
I do appreciate your knowledge and comments .

Jean

What is a .tcw file Jean?
I don't think I can not import that into anything I have.
Is IMSI Design cad 3D?
Can it export stp files?
