This looks like something my kid would try. I don't discourage him. In fact, I give him guidance at the wife's request so he doesn't hurt himself and let him have at it. So far he has built a brake drum forge and a few other things. Not very many kids interested in this stuff anymore.
He is pretty excited about the whole home foundry thing. I just need things to slow down a bit and spend some more time showing him how to use the tools in the garage.
Ok, I am off to finish wiring up a new ignition system in his Bronco. Had to completely tear out the original system and replace it with an MSD setup.
