• 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 sandblasted my fuselage and inspected each cluster. There were a few places that needed to be finish welded. Since I was welding bare and blasted metal, I thought making a good joint would be a cinch. Not so. I had some problems that I assume to be caused by sand that is left imbedded in the metal. I'm going to do some light sanding and wiping with MPK before I go farther.

Anybody had any similar experience with this or maybe noticed the same. that is, problems in welding possibly caused by sand imbedded in the metal?
