Very much enjoyed your video series on the furnace. Note: I made Church bells, melting 350 lbs. copper adding 20% tin, for the proper "Church Bell meta;", then added 1% phosphorus as a scavenger. The 'Church Bell' has five tones, all in harmony with each other. The furnace was made from an old boiler blower, with Kaowool lining then cast-able refractory inside a steel shell, with a tangencial burner opening. A silica graphite crucible, with a spout, and this became a 'tilting crucible furnace'. A 'doer' is one who is not afraid to learn...'from experience'.

+Paul's Garage first attempts at non-trivial tasks are rarely final attempts. So your other furnaces all taught you things. Though it is funny how in hindsight those same things often seem as if they should have been obvious at the outset. But that's not how it works.

Nice vid dude I cant wait to see what you make. Maybe grab a second tank, and store on the other side of property, for when it freezes.

@PaulsGarage

6 жыл бұрын

I have a few tanks actually, but they are all empty except for one. i'll have to get one of those setups to use multiple at once, freezing tanks is just going to get worse when winter hits and it's 0f outside.

I made a fairly decent kale wool furnace with air forced propane. It took forever for the copper to start to melt with one burner so I added a second one. Now aluminum seems to melt really fast with the two burners compared to the one but copper not so much. And when the copped does melt, it seems the dross is throughout the copper, top to bottom. If I try to stick something in there to scrape the dross out, the copper freezes on the tool, and I end up pulling out mostly copper/bronze caked on to the tool, and dross which is caked onto the copper/bronze And if I'm lucky I might get 25% of the weight of Copper that I put in the Crucible so my yields are horrific. I added a small puck of aluminum bronze that I successfully made and added four times more weight of copper on top of it and got out pretty much the same sized Puck that I started with. Lead and aluminum for me was easy, but copper is a nightmare. I need to find a forum for people who know how to do this crap so perhaps I could learn some less crappy skills at melting copper.

Hi Paul, great to see your new furnace just working fine. BTW: here are another suggestion for creative projects, a small bronze bell, nice for Christmas and the kids to call Santa ;)

Some advice on why your torch is acting like that, but first, I see you did homework / took advice on borax and tempering, props for not falling victim to the internet. Misinformation is intentionally given out at many foundries (i work around these guys) to keep outsiders out and stop them from taking the stagnant amount of profit in the industry. Always cross reference, or ask a chemist if you aren't sure. Your torch is doing something called "coughing". It's that buzzing sound, like a diesel engine, its why your torch sucks flame inside it. It means you dont have a high enough velocity coming out of the torch. Its basically a pulse jet without the valve on it. This causes a few issues. The first being that it overheats the torch, making it oxidize faster and crack apart prematurely (this is also why we use removable tips). The second thing it does is drop you total BTU (your max possible heat). And third, though this isn't always an issue (it depends on how badly its coughing and how close the vent is from the surface of your melt), it can cause oxidation, lots of slag / dross. Its pulling in cold air and pushing it out, basically super oxygenating the melt, and further dropping the temp. * How to fix it: First you need enough pressure. We run ours wide open without a regulator, just a pipe valve and the propane tank's valve, which is very touchy. Feather them both to tune it. You can run it wide open and be fine, it's not "as" safe but you're not gonna blow up unless the hose is 10 years old and rotted from sun exposure. To be safer just use a steel braided hose and it wont be able to do much of anything even if the hose is really old and rotted (they last longer too). Second: you need fuel velocity. We use .025'' mig welder tips, but you can use different sizes to tune it. This restricts the flow and acts as its own regulator while increasing velocity. This part on its own is the single most effective thing to swap out when you want to change the performance of a torch. A .025 is perfect for a 1'' or 1.5'' venturi if you want aggressive, fast melting torches. Your torch should hiss loudly when not lit, with the valves open (no sound when shut), it will sound like its dumping propane.. don't worry, its not. It will run wide open for about 2 or 3 hours. We also use unregulated LP connectors. Most have a ball valve, don't use those. Get one known as a "full flow" LP connector. That's another massive upgrade you can get, cheaply. Third: let it breathe. Take the cross pipe out of it, unless you want to use a larger pipe, but you are just complicating flow and mix with it at that point. If you want a cross-pipe, you need to have a very thin one, preferably one that goes in one hole and bends 90 degrees (these are inefficient and dont allow tuning like welding tips do. The King of Random shows a propane torch design, thats the one that most of us use, for good reason. Make one but watch out for his parts list, some of the things he lists like the regulator and pipe / flares are not correct. Double check before buying. That welding tip he has is what i use on mine, and it makes for a flame that slightly melts my kaowoll and sips propane pretty reasonably even when wide open without a regulator. A venturi torch seeks an ideal air fuel mix and adjusts its velocity accordingly, meaning you can turn the flame up and down and it will intake as much air as it needs for a good burn, till it looses too much propan e velocity to do so. Its a simple but elegant design. Dont use a restrictor plate like KoR did, this is not needed in a venturi and using it actually causes a significant heat drop and in some positions, can promote oxidation on your melt. A choke is used in some larger venturi torches but this is more of a safety feature than anything else. They make it easy to light a torch without loosing hair. That feature is up to you, but once the torch is in the forge, remove the choke completely and use the pipe valve and LP valve to tune the flame. We use pipe flares on the rear of the torch to promote laminar flow as much as possible (low turbulence), and larger ones on the front for proper flame shape and helps ensure a good mix. * If the propane velocity is high enough (pressure and outlet diameter), and you have a good torch body design, the flame should be aggressive and make a solid roar, not a buzz. It should burn almost entirely blue, like a giant butane torch, but aggressive. The tip of the flame will have whips of yellows. Till you close the forge, in which case it should go completely blue. It will sound a bit like a jet flying by when you walk past it. Always use thread tape (PTFE tape / Teflon tape) on fittings, including the welding tip. I recommend skipping the regulator, and if you do skip it, and it cant breathe properly even after the design described above, check that the tip isnt jammed with thread tape like mine was. I spent a week trying different things when i first started and spent lots of money just to find it was clogged. Another think you might want to try is an extension pipe behind the welding tip nozzle, a sort of arm to hold the hose away from the body of the torch, this allows the propane to heat up just slightly over a longer distance and has more time to decompress (this can raise the burning temp from a better fuel / air mix at the tip). Make sure you swap the forward pipe flare out when it begins to crack apart. If you dont, and run it without that flare, your pipe starts to get sacrificed and needs a rebuild. So take care of it, swap the tip when needed (hit it with a hammer, lightly, to see if its dead or not. If it is,.it will shatter and fracture chunks off of it, it also turns hazy gray). Good luck and enjoy. It should melt your metal much, much faster and use less propane overall... More per second, but because it takes far less time to melt, because of the higher BTU, it ends up using less in the end. You would be surprised by just how much you have left after a melt.

Just drill out the pinhole in the torch if you want more hear. Not too much though or you have to tweak everything. The bell the air etc. And just wrap the tank in a hearing blanket or aim a heater at it. Either that or use a larger tank and keep it full. Using too much volume of propane too fast will make the smaller tanks frost up in no time.

It’s just a guess, but maybe if you would have used forced air, you could turn the propane to a lower setting, and still get to the same temperature, and consequently the propane tank would take longer to freeze.

different alloys do have different casting properties. Pure aluminum and pure copper are both pretty bad, but cast aluminum (containing high amounts of silicon) and various bronzes and brasses can work with a high level of detail. Other metals like zamak (alloy of zinc and aluminum) also work great at lower temperatures. delft clay holds up pretty well i think, i've never used it personally though. I think jewelry makers use delft clay and gold melts at a similar temperature as copper, so it would probably work. Cant say for sure though.

A readily available (purity unknown to me) source of zinc if you want it, is wheel weights. I saw a video on how to identify the 3 major kinds of metals (lead, zinc, & steel) used in wheel weights. Manufacturers are moving away from lead for environmental quality reasons. Have you thought of using a different dunk tank for your muffin tin? Big box stores around here sell 2 sizes of plastic mixing pans (for tile grouting and the like). The smaller one costs about $15 and is probably big enough (24 × 18 x 6 inches, or 61 x 47 x 17 millimeters) to immerse your entire muffin tin horizontally. Just put a few small stones, bottle caps, or finished ingots in the bottom to prevent melting from direct contact. I'm not sure if that will warp your muffin tin, but I'm curious to see.

Have you seen the video by Tito4re called Making 5 Pound Ingots From Scrap? (8-15-2016) He's got a crucible tool a lot like yours, and a 3-section furnace. (Excluding the burner)

Yeah I’ve seen his videos. His crucible tong thing is the one I patterned mine after. Very simple, and effective

lol im on a quest to make every element except the radioactive ones on the periodic table.

I'm a huge advocate of forced air burners, but with copper wouldn't the trade-off be overshooting the additional air, going past neutral and into oxidizing? The danger is oxygen rapidly attacks molten copper. Personally, with copper, I'll probably try to run as rich a flame as can manage to melt the metal. I've only ever done aluminum, but I've done a crap ton of research on copper and bronze/brass. The only thing holding me back is myself at this point...

Sodium carbonate, borax fluxes make a world of difference

I have some, I was just in a rush at pour time so I skipped the borax

nice video, but could you make you notations last longer so I don't have to go back & pause the video, I guess I'm a slower reader than most. :) Thanks

Can you say 100 lb propane tank? If that is not an option, perhaps you could get another 20 lb tank and swap between the two when one cools down. Or get a big tank of room temperature water and immerse the tank in the water. Obviously hot water would be better, but some would complain that it is dangerous.

I think hot water tank is in my future. I already have the grill sized tanks (because of my grill).

Yes, I have 2 grill size tanks and bought two 100 b tanks too. If you are not in a hurry, you can find them cheap ($40-$50). I even changed the connector on my grill when I ran out of 20 lb propane and hooked ti to my 100 lb tank.

Paul, did anybody ever told you that you hardly ever talk in your videos?

Make a belt buckle out of aluminum bronze. I swear your numbers have jump before you know it will be over 10K Thanks Enjoyed

Cut your cupcake tin in 2/3 so you can just dump the whole thing into the bucket

I love my forced air burner. Doooooo eeeeeeeeet.

ok, I know this vid is a little old and you may not check the comments but whats with the mushroom cloud and the monkey... I'm too lazy to read what you wrote at the end so if its there...I'm lazy...also, do you play Magic...you seem like the kind of person that would.

Get ahold of me i sell burners that can melt copper in 5 minutes using waste oil or propane or any fuel you can get . I also have videos that show how i build them so im not tryna shake you down

Just use the burner to heat the tank back up.........................JUST KIDDING LOL (I thought this would be your kind of humor) Cool stuff isnt it fun to be a grown-up we still play but our toys are more dangerous LOL

Nah. Why waste the propane when you can set your tank in a BBQ grill and light IT to keep the tank warm?

@ronyerke9250

There are warming pads made for starting seeds growing in gardening shops, that don't get especially hot. One of these or a plain old electric blanket might be enough to keep your tank from freezing. Perhaps a heat lamp. Is that about the same as direct sunlight? I think a better solution would be to use forced air for a more efficient burn, so you can slow down fuel flow. Perhaps a combination is best, but IDK enough about that.

We use our torches to heat up the bottle all the time. Just did it today as a matter of fact. If someone says you'll blow up they are sadly mistaken. Besides that it's just the lower parent of the bottle that's frosty anyways so you're not actually heating the regulators.
