• 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.

Hello Everyone,

I am building a Steen canopy on the Skybolt per the 1998 plans. 3M 2216 Scotchweld is the adhesive specified to bond the 4130 tubing to the canopy plastic. Note the tubing is also screwed to the canopy. The benefit of this adhesive is its ability to flex while in service and not debond. I also assume it adhears well with acrylic or plexiglass. It is also an aviation certified product.

The 3M 2216 adhesive is ~$150 / pint. Is there a less expensive alternative adhesive that will provide equivalent performance? Otherwise I will click the order button for my Spruce Order :rolleyes:.
