• 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 am trying to lay out a fixture to build the upper Ailerons and I

can't make the numbers work. I drew it up using and trying to verify

what I think are the critical dimensions, ie the 57.750 over all length

and the locations of the hinge pockets, 8.500 and 11.000.

When I do this I get a *aligned* center to center distance of the pockets

at 33.100 vs the 33.000 that shows on the print. The 8.625 dimension

in the bottom view looks to be wrong also, I am thinking that that

dimension should be to the end of the spar and not to the end of the rib.

Here are a couple of pictures of my lower aileron jig and kind of a poor

pdf attempt of the upper aileron fixture drawing.

If anyone wants to cross check this I can output dwg or dxf files. I can

upload these or email them.

ps: On my lower view in the pdf I am dimensioning the spar only.
