• 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.

Tube Splice Questin

Christmas here in Portland, tubing arrived today!!! Starting to piece up sides and I have a question about the splice. Both 3/4 & 7/8 tube are .035. The fit together is pretty sloppy. Is this normal or should the fit be tight. Have some .049 that the 3/4 fits nice but not spec for longerons. Maybe I am overthinking this. Any input ???

Sorry about the caps. forgot to hit the button.
