• 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.



Test Piece Glue Failure?

I have built 2 ribs so far, and I did my due diligence with my test pieces for each glue batch - T88. I decided to test the first one. It failed at the glue joint, not the wood.
I built the test piece by using a 1/2" by 2" piece of 1/16" ply, and glued a piece of 1/4" cap strip to it. I stapled it into place as I am with my rib construction. To test it, I put the ply into a vise edgewise, cap strip sticking up so I could hit the cap strip with a hammer. I took a small piece of wood up against the cap strip and hit it with a hammer. This should test the glue joint in shear. I really hope I did something wrong with my test method. I have enough trophy ribs already in my collection.
