• 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'm using a Cessna Bamboo Bomber cowling over my Lyc R-680. I'm adding 18 aluminum bumps to the cowl to fit the 680. If i follow the same spacing as the Waco owners i'll have just shy of 1000 rivets in the bumps.


Someone asked me the other day why i dont just bond the aluminum using an adhesive. I dont have a good answer...sure sounds like a good idea. Less weight, less work, smoother finish, and i know some aircraft have used this even in structural applications.


All i've read so far is that care needs to be taken to get the parts clean before bonding. Anyone have some experience in this area? Comments/suggesions welcome.
