I'm reading a great book called "Flame Straightening Technology" by John P. Stewart. I got it on interlibrary loan, not wanting to remortgage my house to buy one. This guy is a genius about using heat to straighten metal or weldments, and the book is worth its weight in gold.
In it, he talks about heating 4-5" wide stripes on 5" plate to cherry red like it is no big deal. He does say you have to manifold several acetylene cylinders together to be able to flow enough gas to provide that enormous heat. He also said to use a no. 200 or a no. 100 heating tip.
It's the heating tip nomenclature that got me. I used to use enormous rosebuds in the shipyards to shrink deck plate, but I never knew anything about them - we just went and got them out of the toolroom. Since I left the shipyards in the '70s I have never seen a hint of another torch this size. Is there somewhere you can buy these? I sure don't see them in Victor's product line!
