Yes, you "CAN", Jim. 
Quite a few guys have build their own furnace and cast aluminum. U Toob has a bunch of videos, and here's a link to a hobby machinist's site:

Be VERY careful about what goes into the smelter - some parts, like transfer cases, transmission bell housings, wheel rims, and VW cases may contain a high percentage of magnesium.
