Mr. Inventor has been very busy living up to his nickname lately. Here are pictures of some of his projects just in the past week.
He built a forge out of an old 20-pound propane cylinder. He had watched a YouTube clip online, and and added his own ideas. He cut off the top of the cylinder and attached a pipe to the lower side to which he attached an air pump. Then, he lined the lower 2/3 or so of the tank with an inch or two of clay and let it dry for a day. He started a fire in it with wood, and then added coal to get a very hot fire. He was able to get it really hot by pumping air in.
After getting the bar of steel red hot, he beat it on a piece of railroad rail with his hammer to try to make a chisel. He later ended up melting this end of the steel, though, when he was experimenting to see how hot he could get it! When he pulled it out of the fire one time, part of the bar was missing.
He made this handle for a chisel with his wood lathe.
He also built this hand-crank bench grinder one day. He spent a lot of time on YouTube trying to find directions for building something like this, but couldn’t find any, so he made it up himself, if I understood right. He wanted to make another, and make a video of it to post on YouTube for other boys to watch who want to make the same thing! He used the bike pedal that was originally attached to the gear at first, then made this handle on his lathe. He likes the bike pedal better, though, because it’s easier to turn. Actually, now he’s saying to take off the pedal but leave the bolt it turns on.
He’s also using his lathe again to make wooden bowls. There has been a lot of creativity here in the past week!
Of course, the boys had to have fun with the forge, too! Besides melting aluminum and making odd shapes with it (Mr. Intellectual has now made a clay mold in which he wants to try casting an aluminum signet ring), this short video shows some of their other fun. And by the way, after only doing this trick four times, the bucket of water was hotter than dishwater!
