• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. 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. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Going over more of the discrepancies on my Pitts project. I found one of the mounting bracket holes oval. Its past the front plate and into the spar. Is it possible to fill and re-drill? If so, what media? Or do I replace the spar?
I feel like its a pretty critical spot. That being said if there is a method that is trustworthy Im all ears.
