• 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.

Here is a Hot Box I am using to cure the paint on my engine case and other painted parts. I am using the Randolph Lycoming Gray paint that needs a 200 degree F cure for an hour for optimal hardness.

I'm using my son's old steamer trunk he used for camp. I have a 250W infrared bulb in an articulating lamp.

Shutting the lid and covering this up with a blanket allows the parts to get up to temperature within 1 to 2 hours depending on the size of the parts.

The Harbor Freight non-contact thermometer works great for checking temps.

A nice exhaust fan in the basement takes away any of the fumes so the wife doesn't complain (too much).
