Step 1: Materials Used
Gas bottle ( WARNING: DO NOT MESS WITH GAS BOTTLES UNLESS YOU KNOW WHAT YOU'RE DOING )
first, make sure the bottle is empty. once empty take of the valve, fill the bottle with water and then leave the bottle for a while. i left it for a week. and once thats done cut the top off.
the chair i used was just for the base.
wheel hub was also for the base; i welded the base of the chair to the wheel hub and then welded the wheel hub to the bottle.
i used 1400°C Castable Refractory.
this foundry works great and i can move it around easy!
the bike exhust i used is used for air flow, which i placed near the bottom of the bottle.
the crucible was made from a gas bottle, i also welded a big nut on the base for pouring and 2 eye bolts for lifting
i designed this foundry to use diffrent size crucibles for the smaller crucible. i drilled 4 holes in the side of the bottle for 2 stainless steel rods to fit in and out of when i need
the lid was just a big hinge i found and some box section so it only goes back so far
