Hi Jim. Trust me, it's fabulous. It must be coming up to a couple of years old now and it's still just as good as the day it was cast. I did make the mistake of not insulating the base and the whole thing needs a good insulation wrap. Look out for my Plaster Insulation video. With that included, it's been an excellent, sturdy but cheap foundry : )

I like this build better than all the rest I've seen. Actually pretty simple and to the point. I built one but mixed my own with cement perlite and silica sand. it was messy and time consuming. After about a couple of dozen lights it became too brittle and started falling apart. I'm going to try your build see how that comes out. Thanks. Joe San Diego, CA USA

That's great news Mark. Welcome aboard. You're sounding British (?) so I'll paste an answer below I've just sent to another casting newbie : ) It's a great hobby and amazingly useful. Sure here you see me casting knives and coins, but there are far more "real" applications like brackets, gears, even art, but these can make boring videos. However, casting can allow you to make stuff engineering companies normally produce. If you've never tried casting at all, make a "plaster" foundry. If you look up King Of Random Mini Metal Foundry you'll see how easily Grant makes a foundry using plaster of Paris. That's a bit pricey in large quantities here in the UK, so try Bonding (plaster) and sharp (concrete) sand for a really cheap UK mix. Three recommendations for you: 1) Make a temporary foundry like King of Random but using the recipe I've mentioned above and in no.3 video (below) 2) If you're sure it's for you, buy castable refractory and make your own as I do here - kzread.info/dash/bejne/oGhm1pWGYcm1qbw.html - just one tip, we all make our first foundry too small, so get an idea of the crucible size you want before you build. Treat my video as a demo, not a bible... make things to suit YOU. 3) The refractory needs exterior insulation and this can be done very cheaply with a plaster and sand mix as seen here - kzread.info/dash/bejne/hmWB2sltdbnOaZs.html (you can also build a cheap, temporary plaster foundry with the mix mentioned - see point 1). In the videos / descriptions you should find links and products you'll find a large DIY stores (Wickes, Homebase, etc, as well as smaller building suppliers). Any questions, etc, drop me a line : )

A leaf blower is great for making a huge flamethrower. I setup a burn barrell for the kids. I used a 44 gallon drum in half.i drilled 50mm holes around 100mm up from the bottom. I did harden my machete but a lot of firewood behind my property. Old trees on the ground.

For the folks in the states specifically the Midwest, Menards sells a 25lb bucket of refractory cement and it’s just enough to do the king of random way with a 2 inch bottom. Just did mine. Curing it currently. Can’t wait! Thanks for the vid vegoilguy

Hope people use steel rivets :-) Although even if they were aluminium I guess they won't get hot enough to melt, being that they are outside the refractory. Great Video by the way!

I had some injuries and wasn't able to do much for two years, but I'm really looking at beginning a foundry build soon.

Thanks for your kind words Tom. I would recommend you think carefully about insulation before you build - that's the only fault with this build. The foundry itself is still in excellent shape (no crumbling walls, etc). I'm revisiting the issue of insulation right now so do look out for a new video in a few weeks. As for crucible, it depends on what you have to hand, what your heat source is and what you're looking to melt. Steel works fine with gas / oil / electrics but tends to get eaten by charcoal / coal... at least that's my experience. Personally I tend to buy to crucibles. They're generally cheap enough on eBay and long lasting too. Hope this helps. Best wishes, Geoff

To increase the temperature you could add an oxygen port and oxygen tank and regulator

Thanks for the instructions, very neat. What's the thickness of the walls? Also, have you considered putting some kind of high temperature insulation between the barrel and the refractory mix?

That's more than big enough for my projects and it fitted nicely into the foundry (you see it in the video). I tend to do most of my work with a very tired looking 2kg (you can see that on the Copper Melt video). If you're new to foundry work, don't spend too much too soon. You can spend thousands and if you're doing top notch work like myfordboy it's probably worth it (I imagine he charges a nice penny for those engines he builds).

Hi Armaan, Thanks for the kind comments. I used a Refractory product that is designed especially for this purpose and you can see where and what I purchased here - www.castreekilns.co.uk/dense-castable-1700c-25kg-bag-869-p.asp This material is designed the withstand high temperatures and remain stable for long periods so in theory in shouldn't need replacing for a good length of time. I don't think you could apply Grants technique of plunging a small bucket into a big bucket to displace the central content. That works with plaster as it goes off in seconds. The Refractory goes off in hours so you'd be waiting a long time plus I believe it's recommended that you don't add too much water to the product... add as little as possible to make it workable is the approach I understand. I hope this helps. Best wishes, Geoff

Hi Kate. I use a crucible purchased from eBay. They vary in price and as I'm not a professional I went for the cheaper end and these have served me fine. Steel containers are commonly used (especially by newbies - I know I did) and will serve you fine. You might keep them forever (some do). It can be dependent on your fuel. Gas and Oil are more forgiving, but charcoal etc tends to 'eat' at the steel container. This happens anyway, regardless of the fuel (the steel starts to flake) but can happen in a single occasion if the foundry is too hot. That happened to my my first time. The trick is not to expect too much at first. Just try it, see what happens and remember that every time it gets easier and more manageable - but never safer! Always be careful and stay safe : )

I think you are professor of making excellent, classic tutorial videos. The subtitles are very good idea for those who have problems with understanding of oral narration - this way it is sure even they do not miss any important information. As you shown, you had problems by removing of burner although you wrapped it in cling foil. Next time try to wrap it in double side silconized baking paper. You should use at least two but better if three layers, wich are independent from each other. Silcone gives actually some lubrication between layers and makes easier to remove the tuyere pattern. This is just an idea, I have not tryed, but I suppose it works.

Knives tend to be forged from steel, rather than cast. Crucibles to handle those kind of temperatures tend to be extremely expensive. Those that you see cast are usually made from aluminium, so they are replicas only. That sort of crucible can easily be found on eBay, Amazon, etc.

Im super late to the party here but i find it very difficult to get my hands on a can/drum like you used here. Are there any good alternatives for a foundry this size. I saw a few ideas with propane/gas cylinders.

@vogman

Hi Alex. You don't really need the drum. It's basically a mould. You could use plastic sheeting and achieve the same ends. The refractory forms like concrete so it becomes a solid shape, allowing you to remove the plastic once it's set.

Aside from water, why didn't you use sodium silicate? A few months back, I made a refractory for a friend much similar to your concept, but without knowing your video existed. By the way, I subscribed because you have a practical sense of thinking, I admire that. I'll be coming back here for references and such. Keep pushing forward.

Great job sir! I am considering making one of these foundries or an electrical one, do you have any idea how much propane gas it is needed to melt say 1kg of aluminum?

@vogman

7 жыл бұрын

Thanks for the kind words. This is a nice easy build and well worth the moderate investment in refractory. As for how much gas, there's just too many variables... how much gas the torch is consuming, how much heat it's giving out, the insulating qualities of the foundry (very important that - see my video on the subject before you build -kzread.info/dash/bejne/hmWB2sltdbnOaZs.html ), the ambient temperature, the purity of the aluminium, etc, etc. In short it becomes a "how long is a piece of string" type question. I think gas is a good way to go as it's very controllable. If you can get hold of used (waste) veg oil, this is typically free and can make a very effective free, environmentally friendly heat source.(I made a really simple one of these here - kzread.info/dash/bejne/qIWu17CIcrK2f9Y.html). I tend to use both gas and oil, raising the foundry to an ideal temperature fairly quickly with gas then switching to free oil for the duration. This keeps the costs down nicely. Sorry I can't be more specific. I hope the above helps a little. Good luck and play safe : ) Geoff

Good man! Another casting buddy. Just what we need. Okay... my advice... try it first. Look up King Of Random Mini Metal Foundry and build that. It's amazingly easy and cheap... and it falls apart after about three uses, but it will tell you whether it's for YOU. If it hooks you, build a better foundry. Next, IF you're convinced, decide what sort of things you're going to cast. Why? Because everybody builds their first foundry too small and it's so annoying : ) And that's the answer to your question about the container... it really doesn't matter what you use. You could use cardboard - honestly. The refractory is where the strength is. But if you can only fit a tiny crucible in your foundry, you won't be able to cast much. A big foundry can cope with a small crucible, but not the other way around. But like I say, try it first. And any more questions, don't hesitate to ask : )

This might confuse you a bit as this is an Insulating video, but it you mix up plaster as I did here and pour it around a good size pattern, like a like paint tin, it will make a nice plaster foundry. It won't last long, but it WILL work. After that, if you're enjoying it, make the refractory foundry in a similar way and then add plaster to the OUTSIDE of that as an insulation (mine is still going strong).

small suggestion for an easier removal of the paint can:before u place it inside the furnace,place around the paint can around the external side some pizza box paper or something similar and fix it on the can with something like insulating tape or similar. place the can with pizza box around well fixed to the can inside the furnace and start pouring the refractory cement . day after u will have a slightly easier life on pulling out the can from foundry.

Thanks Ludo. Always good to have input. There's more than one way to do just about anything and it's by sharing these ideas we get the method that's best for us : )

great effort. i'm just about to turns

Where to buy the repractory and the molting jar like to try as a hubby

hi. can you see any reason not to have a steel sleeve between the fire coals and the sand plaster mix insulation . im thinking a large fire extinguisher surrounded by insulation inside a mettle drum with a smaller heavy cruicable inside all of that .

Hi Calvin, I'll be honest, I really don't know. I suppose the steel will expand and encourage the plaster to crack, but plaster will do that anyway. If the steel isn't thick, the heat will eat through it quite quickly (and extinguisher should last a while). Also if you're looking to melt steel, you don't really want a steel lining in your foundry : ) In truth my friend, this is all about experimenting and finding the best way for you. We've all go different budgets and resources, so as long as you play safely why not give it a try and see how it goes? Personally I would encourage you to go down the refractory route - that's why I made this video - but there are insulation issues. In truth I've just rebuilt the lid of my foundry with 50% plaster (for good insulation) then a 50% covering of refractory (for excellent heat handling). I've yet to test it but I'm hopeful. All the best. Geoff

Thank you for your video Sir Jeff. I'm young & learning, I have a question if it's ok, Can I use clay three holed bricks to forge metals or is it a bad idea ????

No Paul, never use ordinary clay bricks. Even at moderate temperatures like a garden fire, these can shatter, splinter and explode (a tiny bit - but spitting off very hot fragments). You need proper high temperature bricks, like those I used in my electric furnace build - kzread.info/dash/bejne/iq2kz6tsaKyxcdo.html

it says taking temperatures at 1700 which is the melting temperature of brass will this melt brass without an issue and what are the risks of going above that temperature

Hi Nathan. I would imagine you'd be looking at cracking... The point behind refractory, when compared to plaster kilns, is that it stay stable and whole. If you push the temperature too high I would guess it would crack and destabilise, but I'm no expert. Thankfully you can get refractory that haqndles much higher temperatures if that interests you. Hope this helps.

Nathan Saier - you've got a units mix-up here. Brass melts at 1700f/925c. The refractory was good up to 3092f/1700c

Out of curiosity, are you wishing in hindsight that you had built the burner inlet more tangent to the edge of the bore so the flame follows the wall and swirls? Just out of curiosity. The first furnace I built had a burner inlet in about the same spot as yours. It was not and issue when I used my 3/4" reil propane burner, because the burner tube was oversized and I was able to aim the burner along the wall. But recently, I built a forced air propane burner, and it is the same size as the inlet, now the flame blasts one spot on the crucible and you can tell as plain as day that the crucible glows brighter in that one spot.

You're absolutely right. This was only my second foundry built and I planned and aimed to have the heat circulate around the walls. I don't think the video quite does it justice because it DOES do this, but I will admit it could be better. I think we all built better in hindsight : ) I mainly dabble with aluminium and so far I've been very pleased with the results I've been getting. For a small, cheap, easy set up, I really have got no complaints. If I venture further into casting, I might change things a little... We'll have to see. Thanks for your comments. Geoff

What diameter should the foundry be? I can get a 20liter oil drum. It's 42cm in height with a 32cm diameter. Would this be too narrow for a foundry?

The simple answer is - it's up to you. It's about the crucible really... you want to have enough room to get the crucible in and out, but not so much room that you're losing heat, so as small as you can get away with is often best. And how big a crucible do you need? Well that depends on what you're doing. If it's making jewellery, then tiny. If it's engine parts, probably large. I hope this makes it clearer : )

can we use cement ( green - grey colour ) with small rocks instead please replay

+Taimoor Rbeaat A lot of people use cement to make a home foundry. I previously used plaster. This time I wanted the proper stuff and this refractory is easy to work with and a good price. But don't be put off. If you search for a Cement Foundry I'm sure you'll find a few videos out there. Best wishes, Geoff

Good evening sir I have a question, after the oven was built, how long must I let it dry to use it, thank you from Venezuela.

Hi José. The refractory I used requires a minimum of 24 hours to dry, but I think it's best to leave it a few days in a warm dry place until it turns a pale grey colour. Then light a small fire in it - using just a little wood and paper. Feed this fire slowly for an hour then let it burn out. The next day light a fire with charcoal which should burn a little hotter. Again feed this for an hour and let it burn out. This should be all that's necessary : ) The above process worked great for me. My foundry is still crack-free, stable, strong and working well. I hope this helps. Geoff
