Yet another nicely made piece of equipment Hemi. What are you going to do with the ingots?
Good question !! I now have all the stuff needed to make castings, but don't have anything in particular in mind. One day this fall or winter I'll cast something. Maybe I'll make a whole bunch of "Ontario Rodders" plaques like they used to do for car clubs in the 50's .
lolllllllllllllllllll about the only part of the project .i could do is unload the tank and bring it inside ..............................the rest is way way way to complicated for
Sweet! the plaques would be cool, But I gotta know.. Where did you manage to get so many pistons?
Engine builder in Port Hope (John Owen). Most pistons contain steel, so they are considered to be contaminated and will not bring top dollar for recycling. Same with the cylinder heads because of the valve guides and seats.
Couple questions ... aluminum heads obviously have guides and seats that would contaminate the head but where is the steel in cast pistons? Also, I am not fully understanding what you did to the main cylinder and the two sono tubes. The steel cylinder is the body, inside the inner sono tube is left open (for obvious reasons), my question is what is between the cylinder and the first sono tube and what is between the two sono tubes. I am assuming the inner is filled with cement and the outer with insulation but not sure. Cool unit I might add.

Forged pistons are all aluminum. Cast pistons have steel skirts cast into place beside the wrist pin. If you look in the first video, the pile of crap beside the ingots are the steel skirts ( and dross) that I scooped out of the furnace.
Castable refractory ( high temp cement) is poured in between the two sono tubes. When it has hardened, the sono tubes are removed. This leaves a gap between the steel cylinder, and the outside of the now poured 1 1/4" thick furnace wall. I pack ceramic wool in this gap before pouring the top. The wool keeps the outside wall of the steel cylinder a lot cooler, and also the furnace heats up quicker because it's wall is only 1 1/4" thick.
Very interesting , and a great project, a fine looking job on the furnace build, Good stuff!
Wondering, how did you cut the propane tank? How was the gas residue expelled, by carbon Monoxide first or?
I removed the valve and filled the tank full of water, and I used a zip wheel on an angle grinder to cut the top 3" off. Once the top was off, I emptied the water and cut it to the final length. I've heard guys using Carbon Monoxide or argon, but I feel a whole lot safer with water because then I'm 100% sure that there's no danger.
