OT: Backyard metal foundry almost done :), aluminum/brass casting getting closer... Options

[Mueller]

The burner is finished, I got the plans from http://www.backyardmetalcasting.com/index.html

It's a pretty simple propane burner, built from steel pipe for gas lines....cost a few bucks to make (the regulator with gauge cost about $40)

I hope to be melting some aluminum and brass sometime this week....not as loud as I thougt it would be, but it does make some noise <!-- emo&:D -->(IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)<!-- endemo -->

So far my "donor" aluminum scrap will come from some old used 2.0 pistons, a 914 steering rack, possibly an old 15x7 Phonedial that had a run in with a curb...of course I still don't know what the heck I am going to attept to make...

The neighbors are nervous

We have used a lot of SLA cores to make complex stainless parts. Coat them in plaster and cast away.

Same process as lost foam- SLA burns out.

Muller, ya might want a copy of the 1930's books "Amature Telescope Making" vols 1, 2 and 3.

They go into detail on casting aluminum parts in yer back yard using easy to obtain materials. They use a barrel lined with firebrick, charcoal, and a fan blowing into the barrel for the furnace. They cast a bigg ass aluminum fork for a telescope.
