• 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.

Dang oil filler tube is loose again! It came loose a couple of years after the engine overhaul, and I had a shop in Pendleton Oregon re-seat and lockwire it. Then it came loose again. I tightened it and lockwire it. Now it is loose once more. Just a paper gasket between the bottom of the tube and the case. PIA because it is buried behind the Christen Oil Separator can.

And it is aluminum, not plastic. Turning surface seems to be a (loose) 1-3/16", but I can't find a crow-foot wrench in that size anywhere. Anybody got any ideas?
