• 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.

Eight-point Roll

After cutting the center 1 1/2" hole (cut under-sized with a 1 3/8" holesaw 'cause a 1 1/2" holesaw makes a larger than 1 1/2" hole) I spin the plate in a vice and very carefully file it, spinning it an 1/8th of a turn at a time... round and round and round. On DeltaCAD I drew successive holes up to the 1 1/2" and one past it (clearly marked with a dotted line instead of a solid line.) This allowed me to ease up on the hole and keep it circular.
