Thanks, Jim. I had to look it up. The learn'in just don't stop. Terneplate definition from the Internet (Concise.britannica.com):
Steel sheet with a coating of terne metal, an alloy of lead and tin applied by dipping the steel in molten metal. The lead content gives terneplate a dull appearance, a noncorrosive surface, and solderability. The tin (1250% of the alloy) wets the steel, making possible the union of lead and iron, which would otherwise not alloy. While it is still used for roofing, gutters and downspouts, casket linings, gasoline tanks, oil cans, and various containers, it has largely been replaced by other, more durable steel products that are easier to manufacture. http://concise.britannica.com/ebc/article-9380487/terneplate Frank Nelson N51DV - 415C (still in repair and annual) TOA/California > > I believe the photographs of Frank's Stainless Steel Fuel Tank (leaks) > are images of a terneplate steel fuel tank (having suffered one myself) > - I believe I heard terneplate is a cheap type of steel that was > available pretty much as War surplus after WWII and was not suitable > for welding.
