• 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).

I noticedmy drag wires at one station became slightly slack. So the alarm bells started ringing in my head. Sure enough, a drag block had failed. I couldn't find the test piece that I had 'stored' away! I loosened all the wires and proceeded to give all the blocks a good wack with a 5/8 socket and hammer to see for movement. All seemed ok. But it was haunting me, so today I have parred them all off with my best chisel....better safe than dead.


I am also thinking of making the new blocks a little taller for more surface area to glue to. It may not be needed, but it will make me feel better.


This is my normal procedure for glue-up: vacuum the surfaces, blow them, wipe with acetone, apply glue to both surfaces, let sit for 5 mins, then clamp lightly.


Lesson learned: keep your test pieces labeled and in a bucket somewhere, and test them at the right time.
