Casting AL molding box

<< < (5/5)

vtsteam:
Well after all this I paid a visit to the shed where I keep my aluminum. After checking what I had, it seems I would use up nearly everything to make 6 of these -- frugal as they are -- by the time you count sprues, long runners etc., I'm guessing 5 pounds minimum each melt. And with a single large flask to cast them in it's going to take a lot of time and fuel to do 6 pours.

So I think I'd rather save all those resources for doing more interesting work. If I had a couple hundred pounds of scrap aluminum, it would be different. Maybe I will at some point, and will take up where I left off here.

Got any sheet steel and angle iron lying around?  Fabricate some.

Or alternatively use wooden ones and reckon to replace them relatively often.

vtsteam:
Wood it is, Andrew. I'll leave this thread since it's real topic is the very fine flask design by ironman.
