• 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).

shrinking the firewall

Hi all,

I recently bought a shrinker/stretcher which I confess I haven't tried yet. I see some builders have first created an L-shaped piece of aluminum or stainless, shrunk it to shape and then riveted it to the stainless firewall. Has anyone tried creating the firewall with an added flange, starting the bend over a form and then shrinking it to get the necessary right angle? Seems like it would eliminate a whole bunch of rivets if it can be done with accuracy.

Jim
