After having rolled the leading edges of both elevators at this point I decided to go about this a little

different this time.  I recommend rolling one section at a time.  Using the same methods as before with the

3/4" pipe,  I rolled the top section first, riveted....

Then rolled the center section....

riveted...

Then rolled the last section...

and riveted...

But I'm still trying to figure out how to roll and join the root egde and end up with a nice radius here.

There is hardly enough material to even reach and join the 2 edges.  Must have to use the FM here.  ;o)
