Some of you folks know that my next project is the Poppin flame licker. I have a high distaste for tiny parts/fasteners. Therefore I redesigned the engine making it 50% larger. Then I looked at the main frame the original designer called the Standard. I looked at my stock of materials and unfortunately I didn't have a piece of material large enough from which to create the Standard. So I convinced myself what the hell, I'll just cast it. Other than in my profession to which I believe I'm a quite good designer of industrial machinery, I'm very much a jack of all trades/master of none type of hobbiest. Unlike some people here, I'm not that picky as long as it works, and my castings "work". They're never great looking, but then I'm still very much a novice at the whole aluminum casting biz. Anyways, I designed and 3D printed a pattern I believed could be cast "open" mold. It took a few tries getting the sand to hold, but I do have what looks like a serviceable part. (At the time of this picture, it was still hot to the touch and I was unable to clean it). We'll see when I start cutting on this beast. ...Ved.
