My second Job, when I was 16 years old. Back in 1973, was... You guessed it! It was in a Foundry. This one, was actually a Machine Shop, with a Foundry in the Back. I Poured Aluminium Lawn Furniture. Little three tiered tables. And I pored some Brass Parts too. I used simple metal moulds. But, there was another guy, who did the Sand Casting and he taught me how to do it well enough to work on my own. For a while, when he was on vacation. Then I went back to my Aluminium Lawn Stuff. I found it very interesting. But, believe me it was hot in that old Sheet Metal Building in these Texas Summers! I didn't stay there, very long. I went back to my fist job, in a regular Machine Shop. But, I have always had in the back of my mind. The things that I could make, if I had my own home Foundry. A couple of years ago. I did a bunch of research on Home Metal Casting and really got fired up about it;) But, I still haven't done it yet. And also, after reading and watching quite a few videos on 3D Printing Parts at home. One of the first things that came to my mind, was... I wonder if you could do a Lost Plastic Pour? Instead of taking all of that time to hand carve a Wax Pattern or make one from Plaster... Anyway.... All that, to say... This is a very good How To Video on Home Lost PLA 3D Print to Metal Casting. This guy was kind enough to make a Complete. Start to Finish Video for us. He uses some cleaver and inexpensive innovations, along the way. He mentions in the video, towards the end. That he has been doing this for 20 years. And his finished Product, Proves it!:) Also, check out the links below, for more Metal Casting info...

Oh, and yes I have Exploded some Concrete by spilling Molten Aluminium on the Concrete Floor. It was kind of cool, to me at 16. So, I did it again. But, I stopped doing that, when something hot jumped up and hit me in the face. No, I don't remember wearing any of that Protective Equipment. Just some thick leather gloves and my Blue Jeans...
