• 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 recently purchased a Skybolt project. I have researched drilling straight holes in various threads and have seen some jigs, “U” shaped made out of welded material. Someone used a milling machine to make a jig out of aluminum. I am used to working with wood and have a pretty good wood shop, however I don’t weld, nor do I have access to a milling machine. Has someone come up with a way to make appropriate jigs out of wood? Are there retail jigs available that have been used and recommended? The jigs I’ve researched don’t look like they have the accuracy needed to drill necessary holes. I’m talking about 1/4” holes for ”I” strut, 1/4 “ holes for internal flying wire fittings, etc..

lower and upper wings have been built. I’m currently making wing benches as the upper wings need to be glued together. (I have Steen Aerolab backing blocks to glue wings together). The fuselage is complete and was professionally welded by Steen Aerolab.

Any help would be appreciate.
