You shrink yourself??
one of my friends always said: tiny fingers make the best sneakers. guess it works for welding too.
This is my 7-year-old with my 9-year-old daughter looking on in the background. She's actually a little better welder, but the picture of him turned out better. I wouldn't trust my life to anything they've welded, but both can make metal stick together. I figure if I start them out now, I may have a chance of them helping for real before they get so big that they're no more help than I am.
I bet the short sleeve shirt will make him tough..
