I was amazed how quick the aluminum was melting in the crucible and it was a good opportunity to do some aluminum sand casting.
I looked around and I decided to duplicate my plastic scoop.
I used my large wooden flask it was just about the correct size. It takes about 10 minutes to make this easy mold. I used 2 rounded wooden toys to create the sprue and the riser, and my aluminum rammer I made to pack all the petrobond.
After my last few castings I realized that it is very handy to use one big clamp holding the drag, cope and base board tight together. The clamp also makes it easy to move flask around using the clamp as lifting handle. As for the pouring basin I used a tin can to avoid spilling molten metal over the wooden flask. I still have to give it a bit of cleaning and polish but the end result was very good. Now I have a new excellent aluminum scoop ;-)
Here is my video pouring the molten aluminum
