Vevor Melting Furnace: Review Setup and Tips - Is it Worth Buying?

[@CharlesStevens-vi7ky]

I am glad you mentioned rigidizer and the risks of using uncoated ceramic wool insulation. For the home builder there is a pre coated product available and I would hope the manufactures would start using it.

[@TheDoItYourselfWorld]

I am just getting ready for my first aluminum melt in my Vevor 6kg furnace. I have it all put together and ready. Cant wait to get melting.

[@jeffarto8340]

you need to heat the molds up as well. or the bar will have spots and cracks, and will splatter.

[@jamestran347]

you mean warm up the mold?

[@hipyowowtop]

Opinion from a scrap yard’s perspective: Would not suggest creating personal ingots if you’re looking for profit on your scrap. You will have a tough time selling your material and likely downgrading your metal. You won’t be able to certify the metal in your ingots. Smaller yards won’t be able to verify the chemistry and although larger operations could run their tests they will likely downgrade knowing quality won’t be consistent from a garage smelter. Melting is definitely fun, would only suggest if you’re just looking to create cool content online and not looking to profit off this metal.

[@jayc8180]

I agree. Eventually you will find someone that will buy them but it’s tough. Most yards won’t especially if they don’t know you. Surprisingly there’s people that will buy them on eBay. Even at crazy premiums for some reason. Personally I think a few 5 gallon buckets of bare bright solid core is just as pretty😂

[@joeldobbs7396]

I can verify this, I worked at a foundry that processed lots of aluminum, every batch was sparked on the spectrometer with the sheet included with the ingots. One exception was a nail company that paid for aluminum ingots for deoxidizing their alloys, but they only wanted extruded aluminum. Lead would be another exception, we melted down anything from poo pipe to used medical isotope casks for mill anchor. Hahaha, Zinc fires are great indoors, nothing like coming in to a dusting of snow. Oh, and slag is from smelters, what you skim off is called dross.

[@joshp6061]

eBay is huge exception to this, copper melted into ingots (especially when finished/polished) sell for minimum $10 per pound and even up to $50

[@thubprint]

Oh I’m aware, you’re 100% right all the way down 😁 I’m only doing it because it’s a fun visual representation of the content recovered from specific scrap items (and the internet seems to enjoy scrap melting vids)

If you're looking to profit, don't sell your copper and brass to the scrap yard.

[@AndrewMcGowan-vu2cl]

did you temper the crucible first? slowly heat in a domestic oven to dry it out. then heat in furnace to highest temp you plan to use it at, and hold this temp for around 20 min. seems to glaze the crucible and make it last a lot longer without the flaking you saw. experiment with some casting, its great fun!

[@4speed3pedals]

If the lid does burn out at the opening and enlarge, I think cutting a larger hole (square for ease or round if you are up to it) and replacing it with a piece of stainless steel sheet larger than the hole with the exact same size center hole, held in place with solid steel rivets or steel bolts would end future issues. Use a slightly thicker piece of stainless steel if available. I would imagine that as the original steel erodes, the insulation will also. To cut out the patch, an electric or an air powered "zizz wheel" (cut off tool with a thin a thin abrasive disc, some people call it a "death wheel) cut off tool. Just make sure the blade is in good condition, worn evenly, etc. Thanks for posting this. I just got a notification from Vevor about their stainless steel 12KG model. It looks like the same tongs are supplied.

[@joshp6061]

A full ceramic mortar coating is better, and you should always preheat your molds to prevent explosions and get a smoother cast. You can always remelt if you get a lot of holes or a bad cast

You need a bimetal pyrometer to monitor temps. Drill a hole 3/4 upper furnace hight and use an angle so the tip 4" of the thermocouple is to the side of the fiber insulation. Use Sodium Silicate mixed with Kaolin powder as an adhesive to seal the probe hole. It makes a decent mortar also. I built about 20 furnaces like yours that could melt 200 pounds of copper.

[@billymacktexasdetective5827]

The average Joe screwing around on the weekend in their garage doesn't need to monitor temperatures...

[@Slangevar333]

Thanks Tim, I just got one last week and want my first firing, melt and pour to go as well as it can. I have a pyrometer (for firing a pottery kiln) but haven't yet considered applying it to this task. Your install description is helpful. I made cast sculptures 40 years ago using wax investment and also sand casting process. I don't want to overheat brass and do want to monitor the temperature to be able to plan for time and to calculate gas usage. The sodium silicate & kaolin combo for sealing up the kaowool surface sounds like a good treatment and will apply that. I have used a water- alumina - kaolin mixture to keep kiln shelves clean. I think I may add some alumina to increase the heat durability of the coating and reduce the possibility of cracking, what do you thinks?

[@sarlaccstapeworm990]

Mine JUST got to my door!.... Hence me coming here to see what you had to say about it! I feel a lot more confident in the purchase now. I only paid about $120 for the EXACT same setup. With some of the projects that I have in mind to do, I feel like it was money well spent now.

[@timrockman7]

Preheat your cleaned molds. The porosity was created from traces of moisture or something that gassed out from the heated molten metal.

[@billymacktexasdetective5827]

Traces of moisture did not create the porosity. Molten metal will cause moisture to violently expand 1700 times its original volume into steam. An explosion that won't go unnoticed... The porosity is caused by the failure to degas the molten metal prior to pouring...

[@jpansamerica]

[@msoul3248]

I am glad you posted this video. I am new to this and debated making my own or possibly a purchase like the devil forge(before I saw this). I have most if not all the items needed except the batting and the burner to make. I have noticed many saying “its not worth it to melt down” or “your scrap yard may not take it” but I find my need is a little more of having large sized buckets of copper, aluminum, cast(fan motor ends) that I would like to convert to smaller stacking units. I need more info on useable sized quality crucibles (where to get) and tongs and it would be nice if anywhere had a forum where discussion on the topic could be accessible. Thanks again👍🏽

[@thubprint]

I know Reddit has a sub filled with good (and bad) advice! I noticed a lot of the people there strongly discourage buying a melting furnace because it’s “so much cheaper” to build your own. And while I am a huge fan of the DIY approach, I did the math and I think it costs about the same if you have to go buy all the components to do it

[@Bloated_Tony_Danza]

I'm convinced that melting point has a direct correlation to cost. As the melting point goes up, so does the cost of melting it. Anything under 2000°F is surprisingly doable at home but above that and you start getting into technically challenging DIY engineering, and high cost materials and equipment. I had a forge burner project because I wanted to melt inconel and hastelloy (exotic nickel alloys $$$) and had to shelve it because of "lack of funding" lol

[@karlbe8414]

I would strongly advise putting down some plywood under your crucible path. If you spill molten material, the moisture in the concrete will vaporize explosively. I found this out the hard way many years ago. Preheat the mold?

I couldn’t believe this product could be good at the price.I am an experienced sculptor used to foundries so would be aware of the H&S precautions and would feel confident trying this out.

Anyone who is not fully aware of all the risks should invest in studying all the issues and processes involved first. This baby is not a toy and when things go wrong they go wrong big time!.

9:34 Actually, the ceramic wool will degrade with each subsequent firing without a well applied even coat of rigidizer or appropriate coating. Even the coating will eventually break down and expose the wool. It needs to be periodically maintained. Ceramic wool has been compared to asbestos due to some similarities with those minerals. Your assessment of this product was pretty spot on. Some good suggestions for minor upgrades that would improve the product without terribly impacting the cost. Shoot, they don't even need to make the changes. Just put a slip of paper in the box with your suggestions and let the DIYers do it themselves.

A lot of people use refractory cement, the kind of mortar that is used to build brick fireplaces. I think you can buy colloidal silica on Amazon though, I was just fortunate when I googled businesses in my area that there was a furnace and forge supply house in my area. Advantages of living in a horse town I guess!

[@xlerb2286]

I would say if you're going to work with both aluminum and copper based alloys get two sets of equipment and keep things separate. It doesn't take much of one to contaminate the other. I've built a couple of furnaces before and you could do a lot better if you're willing to build a setup yourself. But for someone that's just getting into casting this doesn't look like a bad first setup and going with this could save you a lot of beginner mistakes in building your own equipment - you want to be safe after all. I'd suspect it won't be that durable though (but still good enough to get your feet wet) and if you do stay with it and decide to upgrade I'd plan on replacing most everything.

I'm currently cleaning out my shed. I'd like to melt down the old nuts, bolts, screws, and nails, rather than throwing them out.

You want to melt down steel parts?

[@thubprint]

You can certainly go big if you like, but a few things to keep in mind: the crucibles get significantly more expensive when you get into the larger sizes and they are consumables, then secondly you’ll need to build some kind of lifting and pouring assistance because that is going to be very difficult to do safely by hand. “Dirty” isn’t really a problem when melting copper, you’ll want to remove any potential contaminants that would melt at a similar temperature and form alloys like aluminium/lead/zinc/nickle/brass/tin, but steel will just float and get skimmed off and bits of dirt and paint and dust will either burn away or get skimmed or fluxxed

By kitchen gas, I assume you mean natural gas. Yes it would be possible but you would need a new regulator (since this is how you adjust the temperature) and a new orifice. You could drill the existing one out if we know how many BTU the current one is and you know how to read the BTU charts.

so... point of safety here.. . If your threads are damage, replace the part. PERIOD. You should ALWAYS use the teflon tape rated for propane / natural gas on your fittings. With temperature swings, come metal expansion, and contraction. The felon is there not only to prevent mismatched threading leaks, but to help combat leaking because of thermal retraction.
