In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web.

Hi all,

I've got some old spars from my Citabria and was wondering if they can be cut up and used as cap strip in building wing ribs. The grain isn't as fine as it is in the 1/4"x1/4" spruce cap strip that I bought a long time ago. Does it matter? I looked in AC43.13 but didn't see a specific reference to grain density for different wing parts.

Thanks!
Bart
