• 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.

I’m in the process of rebuilding my Marquart Charger. It’s essentially a ground up restoration. Right now I’m working on building a new wing but I’m also building a new firewall. My biggest challenge with respect to that is how to make the formers (part no. 921). It appears on the plans that the former is 3/4”x 3/8” U-channel. Since I was unable to find that online, I bought 3/4”x 3/4” square tubing and cut it in half and then tried to form it to the shape of the firewall. It was difficult to fit so I’d be interested to know what some of you have done in this situation. Would it be possible to use 3/4” 90 degree aluminum angle instead? If you have pictures, that would help, also.
