Puddles, I read everything that you put on this site. You've taught me some useful things that's improved my welding. You do some beautiful work, and can back up what you talk about with photos like the one above. I have to say that you remind me of my old welding instructor, and that is a compliment. I'll never be a really good welder - just adequate, and I know my limitations. Last week, I made a hydraulic tank, and decided to pressure test it before I painted it. It looked pretty sharp, but 20 psi and a squirt bottle of Windex later, and I had bubbles everywhere. I finally got it airtight, but it was no longer pretty, ha. Thanks for all of your informative posts!
