I can't imagine why he had the marbles in there!
Because he's a weldor, and he could figure out how to do it without shattering the marbles unlike the 4 guys with bearing balls in theirs.
Hell, I'm looking at it wondering if he popped them in there or welded it up around the damn marbles.
Either way, I'll throw lead work at that man and see what he has to offer. He might be the problem solver I need on a miserable job.
