• 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 had a request for more pics and further explanation of how we made our nose ribs. Hopefully the following will fill in the blanks.

We made our jigs out of 3/4" mdf which is very easy to work with. The above jigs were made to cut out the inside of the nose ribs with a router. At this point the 1/4" birch is still cut in rectangles to fit between the stops on the jigs.

Then the outside shape was rough cut with a scroll saw. A bandsaw would have worked just as well.

The outside edge was trimmed with a laminate trimmer and bottom bearing flush bit.

Some of our nose ribs were a D-shape and most were open ended like the letter C. For the c-shaped ribs, we put a thin stop at the end of the jig. For the D-shape we made a plug that fit in the hole and attached that to the jig. A clamp was used when necessary to hold the ply to the jig.
