Hi Peter,

Coincidently,  a mate of mine Greg Poole,  the local Oz Velocity 
agent is doing a very similar thing - he's about to convert his tractor 
shed to a hangar,  and one of the members of our local SAAA is a  
" Strukchahz Inginnah" and is 'on the case' as I write.  He works for 
a mob who builds highrise apartments,  and is incidentally also 
building the neatest 3/4 scale SE5A you ever did see.  

So happy to share the info.   Don't know how quickly you want this 
done. I'm going to an airshow with the guy this weekend.  Give me 
some idea of the Roof and Wind loads it needs to support and a 
rough sketch of the building and I'll talk to him on the way down 
this weekend.

Alternately,  subscribe to Paul Lamar's ACRE Newsletter and ask 
HIM to design you a nice Pratt Truss. He's good at that sort of 
thing.  He's got CAD and FEA (Finite Element Analysis) software.  
Just DON'T mention Electric Water Pumps or my name!! }:>)

Cheers,

Leon
