Casting Aluminum w/ Homemade Furnace
March 6, 2010 - 2:22 pm
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…
