• 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-strut welding

I plan on tack welding the elements in situ. My welding is not good enough to finish weld in situ [some areas are not possible anyways due to burn risk], so I plan on removing the tacked struts and taking them to a TIG buddy. As I understand it, I am going to have some movement. The Manual suggests that bolting the box section to angle iron will help during welding. I was thinking of being more elaborate and weld me a angle iron 'cage' and bolt the strut in top and bottom...thoughts?
