• 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.

Welding and jigs - Stupid Question 437

I've tacked welded the one side of the bungee truss. It's still in it's jig.

Obviously... it's a little warped from applying heat to it.

It has lifted about 1/8th of an inch from the jig, where the tube would connect into the longerons.

(Finally getting to the question.) Do I need to take the truss out of the jig and tack weld the other side, thus maybe straightening it, and then place back into the jig to cut the holes in it ? I'd think it would just warp a different way and not be able to place back in the jig.

I've assumed before and done things wrongwith that assumption.Throwing out the question for those that know.
