• 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 attempting to square up the 1st rib bay. The wires are all pretensioned to 1 1/2 turns on the front nut except for the front inboard wire which is pretensioned at the rear spar if I understand the directions accurately. I'm at 3 1/2 turns total on that particular wire and it's dimension is still about 1/16 longer than the sister wire in the bay using trammel points. I've backed off the other wire to where it's barely finger tight. So close but not quite there. Does the 3 1/2 turn limit include the initial 1 1/2 pretension or am I allowed 3 1/2 after the pretension? Any guidance is appreciated!
