Nice job. I'm working on something similar. A 40 gallon pressure tank, cut the same way, similar hinge, but using aircrete for the refractory. Finishing today, taken several pours, built my own foam gun. Using water glass for finish coat. Intended for forging , and foundry. Gas nozzle assembled and finished, tested. It's heavier than I wanted. It's mounted on a cast off heavy duty barbecue grill frame. Thanks for sharing.

It’s been working well for me. I went back and made sure I coated all the wool with the wash. You don’t want any to be exposed. In the video I left the top uncoated. Im sure improvements can be made but so far it’s been working for me.

When you use kao wool you need to seal the sides. Its essential fiber glass and you inhale small particles. IforgeIron has information on this.

Do you have a list of all the tools, parts and any associated items to gather before beginning the project? I have found your video to be the best and above all, easiest to follow along.

I'm wondering, how did the hinge hold up, and would you change anything? I'm still assembling mine and think I might have to weld the hinge and also weld some handles on?

You should have left the tank full of water when you cut it. Gas remains adhering to the metal surface and is released by the heat of cutting and welding.

What size crucible would a furnace of this size hold? Looks like a #6?

Love the design, I'm making one now. I do have a question for you about your refactory bottom, did it Crack at all? I had to pour it twice. First one Cracked and I tipped sideways to get debris off the top and it fell out in pieces. 2nd one I welded a piece or rebar on the bottom to give it something to bind to, and its starting to Crack! Still curing will see how bad it cracks

@lundgrenbronzestudios

I used Mizzou refractory wich in known for being very strong. But I also made sure to heat it very slowly so the water inside was driven off slowly. Even if it is cracked though it shouldn’t be a problem. It can just sit there can cracked. I’ve never flipped my furnace upside down so I’m not sure what would happen if I did.

I bought that same tank at my local metal recycling facility. I went to ask about them. The guy at the window told me to go pick out one and have someone weigh it. Most of them didn't have the valve. That's one step I don't have to do. I ended up paying a whole $3.

How big does the burner hole have to be? I made it slightly larger than the burner diameter and my burner goes out fairly quickly when I add the lid. I am assuming that my burner hole is too small. Any guidelines? 1.25x, 1.5x, other, burner diameter?

The burner hole shouldn’t need to be much bigger than the burner. I’ve completely sealed mine with ceramic insulation and it works just fine. I’ll tell you where you can go for help. “Backyard metal casting and foundry work” Facebook page has very knowledgeable people who can solve pretty much any problem you have.

You said that the burner was a one inch burner. Is that an outside diameter or inside diameter? Also so while i was reading the comment, apparently most people don't read the comments before they post a comment, I think I saw that this fits a number 4 crucible. Is this correct.

Great video!! How much or little cement do you i could get away with? A 50lb bag at the store is almost a $100 they have 12.5lb bags for lot less. Do you think 12.5 lbs will be enough for the bottom and maybe the sides if I don't make it to thick? I'm on a real tight budget. Thanks

@lundgrenbronzestudios

Well I don’t know for sure but I think 12 lbs would be just fine. As long as it’s refractory cement and can take the heat.

It just makes things more challenging. Bigger furnace means heavier crucibles, so you might have to do a two man pour. Get big enough and you need hydraulics to lift it. And those foil suits to repel the heat. But you could make one out of an old keg or hot water heater and that would be ok.

Griz Lee as for refractory cement I bought a 50lb bag for about 50$. You can use only refractory cement if you just put a tube in the middle and fill the tank with about 2-3 inches of cement. That way you wouldn’t need the ceramic insulation. But make sure it’s rated for over 3000 degrees if you do. As for how many ft of ceramic insulation? I can’t remember but you will want the higher rated stuff. I think mine is rated for 2800 degrees, and you will need enough to fit the circumstance of the tank, plus the width of the lid. I bought mine by the foot at a fire brick store. If you don’t have one you will have to by a roll of pre sized packages. So just pick one you know will have enough.

No. It’s not the best idea to do that because the cement is such a “heat sink”. It soaks up the heat and takes so much longer for for chamber to get up to melting temp. The time and extra fuel used each melt isn’t worth it. But technically you can do it that way. I just wouldn’t recommend it.

In the end there are many ways to get it to work. It’s just a question of what is best.
