For fuel I used bbq briquettes and a hair dryer for air. For bronze I cut up some copper piping mixed with solder (60/40 tin, lead), cant remember the ratio I used to mix it.

By mold I guess you mean for the castings. I tried sand casting a lot at the start which didnt work well with lost wax castings. Now I use plaster of paris, fairly easy and brings out a lot of the details; to dry it I put it in a box filled with foil heated by a hairdryer but now that ive got my own place I'm just gonna chuck itin the oven at 110 C for a few hours. First bronze casting I didnt melt enough and the next two I didnt add enough exhaust vents so it basically turned into a volcano spewing molten bronze. I actually havent made a single proper casting that came out perfect however ive got a good feeling with this one, just gotta make those vents bigger. Ill be posting the mould making process after I finish the furnace. Finished work early soim on my way home now

Pic is the way I used to make gears, took over an hour and a single crack meant you have to start over again

i heat the white knife and cut the basic outline before making the final shape with the stanley
half way there...
