• 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 starting a project and considering plywood ribs. I have access to a CNC Laser, so I can get ribs cut in nothing flat.
What is the proper way to build ply ribs?
What I've found so far is triangular cutouts and capstrips.

Since this is a predominately wood oriented site, at least for wings, I'm asking the knowledge base here.

My main reason for ply ribs is expediency. Get er' done!

Thanks...
