I have a 350th Chevrolet (I think so) that has paid its debt to society. He had a hard life and definitely had a few visits to the machine shop. So I decided that making a table out of it would be a good use for it instead of a crusher. My biggest problem is that I was trying to weld one of the pistons to the block and it seems like I can't get a good weld on it. I'd like to think of myself as a half-decent welder. It just didn't penetrate as it should. Any suggestions on how to get a good weld in such a project? I think I'll play around with an old cast iron block and a broken piston to see if I can figure out what I'm missing. The best combination I got was the wire speed of 135 and 19 volts, but I could still break it with my hands.
