Casting Aluminum w/ Homemade Furnace

March 6, 2010 - 2:22 pm 5 Comments

Here I am casting a part for a Crayford Style Focuser to be used with a 8″ Newtonian telescope I’m building. I’m using a propane furnace, a graphite crucible, and the “mold” is a tin soup can. I need a stock of aluminum about 3″ in dia. Before you say it, I know it is not safe to cast metal with flip-flops and shorts, but it’s the middle of summer in Phoenix here…

    What an idiot! At 1:28 when he brings his bucket of scraps into the frame, you can clearly see he is mixing 2024 and 6063 with his 6061 alloy. No wonder you have so much dross, you might as well throw some 2090 in there while you are at it and call it a cement. Jesus Christ!
