Subject: | Thanks for the spar info!!! |
--> Pietenpol-List message posted by: "Jim Markle" <jim_markle@mindspring.com>
I'm continually amazed at what incredible resources we have in this group!
Having a good local EAA chapter is important. But having this group really
makes the process amazing! (In fact, the spar article from Sport Aviation
and the NACA Report
No. 344 were mailed to me yesterday......)
Thanks for everyone's help/feedback. The numbers are in and I'm quite
satisfied that an I beam spar design will work just fine. A 1/4"(quite
adequate) or 3/8"(probably more than adequate) plywood web is what I'll use.
So full height ply with 1" tall strips of Doug Fir, each side of the top and
bottom, to build out the "I" design.
I found that a number of British Piets are flying with an I beam spar design
that incorporates aircraft quality plywood webs in the 1/8" thickness range.
So actually doing the calculations can result in a good safe structure
(estimated 1200# MUAW) with a lot less than my "overbuilding" tendencies
would dictate!
Thanks again.
Jim in Plano, TX having just completed my second Tech Counselor inspection
and it looks like I'm on the right track! :-)

Is Warren D Shoun looking in?
If so can you send me an e-mail so I can return some information. The
address I have keeps bouncing back.
Thanks
