• 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).

I am about to build the engine cowling on my AS II. There is a nose bowl, and the rest is made of.025" 2024 T3 Alu,with atop and a bottomcowl and hinged side doors. If only made by aluminium plates it will no doubt be too flimsy, so some strengthening membersare needed. Here the plans are not so clear. It shows dimensions of two steel channels on the uppercowl. It also shows channels on the bottom cowl but only says "channel dzus fittings " . No dimension of the channels.

What will you suggest will be safe to use as stiffening members onthe aluminium plates of the cowling ?
