I appreciate your videos. No gimmicks. No bs cartoon thumbnails. No rave music. And no pleads for ‘like and subscribe’. While I don’t personally do any cast iron work, i enjoy watching a skilled craftsman such as yourself.
My dads uncle Alan Forest was a black smith by trade and was very knowledgeable in metallurgy. He worked in the ship building yards during WW2 on the east coast of Canada, doing many types of different iron fabrication. He was very knowledgeable in working with coal forging iron work. After the war he returned home to the Maidstone area where he farmed and had a black smith shop and did work for the people around the country who came to his farm. Dad said he knew quite a bit of the old school ways and uses of how to make his own steel.
Suggested something half as ingenious as your pouring machine to another RUclipsr and pretty much got called a loony. You've got yourself a really good setup! Just got to get mine off the ground.
I'm delighted to finally find someone who knows how to sand cast properly. I learned in Jr High, and have been annoyed with people on RUclips ignoring basics of the process. Kudos to you!
luckygen1001 yeah... Some years later, I went back to see if they'd let me use the facilities to make something for my wife. That's when I found out that I only had to the end of that school year. The next year they'd be in a new school that didn't have the shop facilities for pretty much any metal work. (Sigh)
We had foundry shop at Brooklyn Tech in 1957, but we only made the cope and drag with a wood pattern and never poured metal, except the last day the teacher poured aluminum.
Edwin Wiles It seems to be the way "education" goes these days. Forget the trades apparently. Well, somebody has to actually do the work! I learned sand casting - believe it or not - as a Freshman in high school. That was 1984 in Wolcott Connecticut, USA. They still had a full on wood working, metal, auto and printing shop and it was not a vocational school! My favorite classes by FAR! I would bet good money that those "shops" are long gone now. Sad.
@@JViello thinking about it, it really does seem to be that the local schools carry whatever skills training that the local job market needs. There were foundries and metal working businesses when I was in school, when those businesses closed or moved, there wouldn't have been any reason to teach the skills locally, so the school didn't include them in the plans for the new school building. Understandable, but it still sucks.
As my traďe was in ferrous and non ferrous work I have found this extremely interesting as I still have my own old tools of trade. You have possibly reignited my interest again.Thankyou
really well done. We need to see your burner and blower and pump design for the waste oil and diesel fuel burner for the furnace.... can you make a video on that ??
I love your channel. You’ve taught me a ton. I’m always open to new info and you give plenty of it. Thank you for sharing with us my friend. God bless and stay safe sir!!!!
Great video and extremely interesting. Our technical college teacher gave us a memorable demo 40 years ago and scooped off the glowing slag and dropped it in a pile on the concrete floor behind where we were standing. and carried on with the demo. A few minutes later there was a load explosion behind us and we were showed with hot concrete and slag, as the laboratory floor blew out leaving a smoking crater and some of us with burnt holes in our trousers!
Thanks for an excellent starter video.I once had the experience of watching a hand operation casting man hole covers.They were casual as hell but turned out a lot of covers. Lot of know how lost there.
I used to work in a Foundry, MJ Allen. We made all sorts of stuff, I was a fettler but I enjoyed watching the blokes make the castings and moulds. When hand making moulds for cast Iron they would use a white, chalky looking liquid which they painted over the sand and it blocked up those grain holes that make the castings look rough. Unfortunately I can't remember what it was called but it's worth asking around, I'll see if I can contact the blokes I worked with.
In 1970 I mixed sand for the Arkansas foundry that cast molds to make parts for Coca-Cola bottle capping machines. They didn't even have the sand mix written down, just some guy told me once to take so much of this, of that, and of something else, wheelbarrow it over and dump it in the big mixer, let it run for awhile, then wheelbarrow it over to a pile near the casting floor. Of course I got the mixture wrong, forgot which sand got which amount, and ruined a half-day production. They still didn't write down the mixture anywhere, but I didn't screw up again. It was 120F inside the building, and I lost ten pounds down to 125 . I quit after a week, but only because the room mate with a car run off and left me on foot with no way to get to work. I had one paycheck, and a very painful swelling of one earlobe. I had to take a Greyhound home to Texas and parents and a family doctor who lanced the boil for free. So much for my first try at independence. Grrr.
Great video. I have some time on my hands these days, bought a small furnace. I just changed the brakes on my buddy's truck. Looks like I have some experimenting to do. But first, I want to make sure I have a clue as to what I'm doing, and do it safely. Thanks for making this video. :)
yeah mate, its been sitting in the "To-Do" bucket for a long time, while I get my lathe and mill rebuilds completed. Finally got those both in and working now, so have resumed work on the electric furnace build... ruclips.net/video/kiWX_cyydqg/видео.html I'm really itching to start melting down some of the piles of scrap around the place
Very nice bit of work ! I protect my concrete floor with bats of fibre glass insulation instead of sand. It's a lot easier to clean up, but it creates a "no walk" zone. I always look forward to you video postings. Thank you !
When I was working as a ladle operator on steelworks, we used a mixture of water, diesel and compressed air to heat up the ladles. Started with diesel and compressed air and then we mixed in pressurized water in the burner .
Well... I never had to break the rotors. My furnace held a full ton of rotors with room to spare. And our flasks were about 6 feet long usually. I did not have that funny cart to wheel around my crucibles. I poured everything by hand and crucibles were measured to amount of iron needed for each casting Good job. Good video.
What was the tank of propane in the background next to the blower fan? Pressurized waste oil. Working on vehicles in a small town, the guy who owned it needed heat in the shop. We place a 55 gallon drum outside, with a tire valve in the bung, after filling it, air pressure added. The draft tube went to 2" off the bottom, ran inside to a valve, but we dripped it onto logs in the double barrel stove. One load of wood would last all day. Boy, you could tell when the auto tranny fluid started coming in. It burns way hotter than just used motor oil. We could get 2 vehicles and 1 school bus inside & close the door, so it heated a large area, but we used a box fan behind it about 5' away.
Wow it turned out really well! I was helping my father change his rotors and pads recently and thought what a waste it is to throw out or return the rotors. Now after watching this I see a reason to even keep the oil! Can't believe it required almost 11 quarts worth plus around 3 quarts of diesel but if it's recycled motor oil the diesel is cheap. Problem I see for me is getting setup in the first place would cost prohibitive here in Florida as there isn't a lot of industry in the southern US historically, so it would all need to be shipped quite far $$$.
$$$? They got's lot'sa cars with disc brakes in Florida don't they? My furnace shell was free, a really big old water heater tank. Made the furnace barrel and a 5" ring of it for the lid. A friend at a local cement plant gave me a few bags of out-of-date High temp refractory, (lines the huge rotary kilns that cook limestone into cement) I built a 20' radius swing crane and hung a small Harbor Freight 500 pound electric winch ($50?) under the I-beam on wheels, because my large crucible is just a 12" chunk of 8" sched.80 (3/8" wall) water pipe (it was a free cut-off and I've got several feet left) with a scrap 1/4" plate bottom and 1" square lugs welded on, to lift it out of the furnace. I lined it with more of that refractory. OK, that's my big non-ferrous crucible, I think I paid quite a bit for my large silicon-carbide crucible for iron. As much free, used motor oil in Florida as anywhere else right? Does $$$ mean $3? OK, I did pay nearly $100 for my new 160 Amp Lincoln buzz-box welder, back in 1960 or '61, but it's been paid for many times over. I just remembered, I used a brake disc from a Pontiac Firebird to lock the the crane I-beam swing 10' up on the mast, with rod to an over-center, (locking) handle below. And luckygen, I live in the California "High" desert, preheats my furnace feed. ;-)
You sir, are not only an amazing artist but a magician as well! Nice work on the vids. They are a task in themselves!! Thank you for sharing all your work! Very informative and enjoyable ❤️❤️❤️👍✅
Thanks for the video, wanting to restore an old coal forge so might have to try my hand at casting iron myself. Although one of those things that sometimes having a professional show you or do it can make things easier in the long term
@@luckygen1001 Thanks for the comment/reply. Not in the coal one as its a historical piece that is more for the experience, this video years ago was actually my inspiration originally to build a furnace/forge but due to lack of experience + safety forethought about oil/diesel mix i caused a fire due to a leaky valve, so have only been using Gas (thankfully i had foam extinguishers on hand for my vehicles/Equipment) As my workshop is now full of old cast equipment from 1900-1960 i want to go back to using the oil/diesel mix with gas to do my own castings as looked at electric but don't have the coin for that setup as yet. 100% know that before i even try do any iron casting (I have done Ali,copper,brass on small things) that i need to get some hands on experience with a knowledgeable person that can help me mitigate the risks and provide advice (same reason i have a professional engineer that i can double check things with when doing machining work) Thanks and didn't mean for the long reply
your videos are absolutely inspiring! i am getting into scraping but castings are expensive. now that i know you can make them at home with some throw away brake rotors and some motor oil / diesel,.i will definatly be looking into making a furnace.
I've been collecting brake rotors and wheel hubs for a friend who has a furnace that can handle cast iron. Working at a car dealership I have a virtually inexhaustible supply. :) My furnace barely manages to melt aluminum (but that was the design goal, burning wood scraps to melt aluminum), but someday I'll have time and room to build a nice one.
Try changing from wood scraps to ordinary barbecue charcoal... that’s what they used in the “Bronze Age”. And if you want to get really serious use coke
I was just at a "u-pull" auto parts junk yard where you go strip whatever you want off cars. There were brake rotors everywhere. I instantly thought of this. I think they were charging $10 bucks each or something.
Use a slurry mix of graphite and paint the surface of the mold this will eliminate the ""quake" marks or scabbing. It creates a barrier between the iron and sand.
If you do another surface plate, design it with 3 feet instead of 4. That is how most of them are done so they won't twist under their own weight. The twist us usually tiny, but if you are going to scrape it flat to 10ths it is enough to cause a problem. Great video
As a person has previously mentioned about your blast furnace, I would like to know how you built it and what you used for materials in the construction of it. Thank you very much for this video
All you need is a salvage yard, fund engine cranks, brake rotors, alot of exhaust manifolds are iron, large diesel engines, about everything is iron! Ya just gotta give it a think!
Fantastic video, great pics and awesome audio. I am just getting into casting and found this video really good so have subscribed and will back track now to learn more. Keep them coming
good videos you made, and i remember the goldsmith use borax powder tomelt gol easily, and one the ore is melt he poor a tea spoon of table salt to evaporate the ipurities, the impurities makes gold carcking.
If you want more rotors (or other scrap and cut off bits) beer works wonders at garages, scrap yards and machine shops. Scrap iron/steel prices are quite low nowadays so it's a good deal for all concerned. Garages save scrap to be rid of it and few make enough profit to matter.
15kg in 50min from cold start, without preheating air. 👍👍👍 That is excelent result. Your furnace ist the best and moust effective i have ever seen on RUclips. And also more effective than my furnace. Great job very nice 👍
Back in the days of Galleons and cannons firing cast iron balls, a foundry in the UK used to dust their molds with Plumbago, which I believe is Graphite. it was only mined in the UK at that time and this process allowed the casting of far superior balls to any other country. I live in S. Australia, where do you get your Ferrosilicon from? The foundries that I used to work on furnaces, have now closed up.
Really nice 👏, I use graphite sometimes but it's just to make really rough patterns release from the sand but it also helps Sarah there's a refractory surface against the facing singing as well and I'm surprised you had to Chisel out the sand in the webs but regardless it looks like it turned out great. I made a surface played a couple years ago and it did not turn out anything half as nice as what you got there
I have an old vise that is cracked. I want to try my hand at gas welding it with cast rod. The only cast rod i can find is very expensive. Some people say to use piston rings. I was just thinking of this video and came back to it. I wonder if I could cut some longer strips close to the center and use the rotor material? I wonder if the alloy is too hard? Ill plan on doing a long post heat and cool down.
Because to be human is to apply a rich consciousness to causing change in the world. The change can be anything. It can be picking up a candy wrapper or washing the dishes or holding a baby. Some changes are that simple, other changes are a matter of deep vision and the disciplined dance of step-by-step action. I don't have any of the tools this man has. Hell, I don't even know where the hammer is, but watching him do that work made me want to sun out and cast something for which I have no use whatsoever. I get your fascination.
Hey maybe a suggestion that could help you do less work for the cast iron from the discs. My suggestion is go to your local automotive shop that cuts rotors and this could be a autoparts store or a repair garage that cuts rotors. They always have cut waste from the rotors they will gladly give you for free, heck I would have given you small buckets due to the weight when you discard the waste cast chips. I also think it would melt faster than a solid would. Best regards.

Borrow money from parents, get a bicycle, pay parents back, keep the job.

Really long video dude. Make it more shorter.
"Make it more shorter." You can make your sentence shorter by saying "make it shorter". Then it'd be more better.
It was 40 minutes, showing the same actions being done six times. The comment has merit.

Very cool! I like your pouring mechanism I see people who are literally 3 ft away from pouring and I cringe at the fact that anything can happen.
you are doing hard work in your own shop that is great thing you can do in your life and feel it all day
Fantastic video. Very detailed. I loved the camera angle while you were wheeling the molten iron in.
When I was working as a ladle operator on steelworks, we used a mixture of water, diesel and compressed air to heat up the ladles. Started with diesel and compressed air and then we mixed in pressurized water in the burner .

You make it look easy. Well thought out.
I casted at multiple jobs doing lead now was doing steel in Alabama an casted counterweights for forklifts great cast very clean too
Boy do I need to get crucibles big enough for that. Small crucibles just won't do for my project
Really interesting process,....

Don’t know why but haven’t seen your videos for a while. Anyway glad to be back and learning from you.

Full PPE. Well done flawless video presentation
After watching these DIY youtubers with trash cans and kitchen tongs was pretty nice.
98.2% yield is pretty good in any synthesis. I'm impressed.
Older cast irons tend to produce lots of slag and the yield is about 94%.

If you want more rotors (or other scrap and cut off bits) beer works wonders at garages, scrap yards and machine shops. Scrap iron/steel prices are quite low nowadays so it's a good deal for all concerned. Garages save scrap to be rid of it and few make enough profit to matter.
Holy shit... That's 1 hell of a forge!
I would imagine old iron frying pans and pots would make good patterns to duplicate them with...replicate some fine antique stuff that way!
Yes it will but the iron needs to be very fluid to fill up the mold.
Owned a mechanical workshop here in brisbane 22 years. Probably dumped thousands disc rotors over the yrs.
Ok master, good to see you again!
great stuff man.I can't wait to get melting again.
a 2018 video that feels like it's from 2007
Legit checked to See if it was
Yea first i think this is a video from early youtube
15kg in 50min from cold start, without preheating air. 👍👍👍 That is excelent result. Your furnace ist the best and moust effective i have ever seen on RUclips. And also more effective than my furnace. Great job very nice 👍
Vielen Dank für das Ansehen meiner Videos und Grüße aus Australien
@@luckygen1001 Es war mir ein Vergnügen. Ihre Videos waren sehr Lehrreich 👍👍👍
Back in the days of Galleons and cannons firing cast iron balls, a foundry in the UK used to dust their molds with Plumbago, which I believe is Graphite. it was only mined in the UK at that time and this process allowed the casting of far superior balls to any other country. I live in S. Australia, where do you get your Ferrosilicon from? The foundries that I used to work on furnaces, have now closed up.
Try cast metal services Australia, that is where I got mine. You may have to buy a minimum amount.
Did you build your forge? Im curious about the build and oil/diesel system. Haven't seen many being used but sounds like a cool idea.
Thank you for your time and lesson. You my friend are a pro
What is your startup procedure for a hot furnace,propane then blower,then oil ,like a cold start ,or will oil self ignite,then blower?
i could listen to you all day, this stuff fascinates me...thankyou
Great content, so glad I found your channel.
A press with a vee or ball bearing pressing insert might break the rotors more easily than grinding.
I don't have a press but could use a hydraulic jack instead.
I was thinking that my 25 ton log splitter could work
I just bash em with a 4 lb drilling hammer. I often do it on accident removing seized ones for replacement.
A sledge hammer would work well, with proper clothing and equipment of course.
This was fun to watch, thank you.
Really nice 👏, I use graphite sometimes but it's just to make really rough patterns release from the sand but it also helps Sarah there's a refractory surface against the facing singing as well and I'm surprised you had to Chisel out the sand in the webs but regardless it looks like it turned out great. I made a surface played a couple years ago and it did not turn out anything half as nice as what you got there
Very Very interesting and enjoyable to watch
I like your set, very clever man!
I have an old vise that is cracked. I want to try my hand at gas welding it with cast rod. The only cast rod i can find is very expensive. Some people say to use piston rings. I was just thinking of this video and came back to it. I wonder if I could cut some longer strips close to the center and use the rotor material? I wonder if the alloy is too hard? Ill plan on doing a long post heat and cool down.
exceptional video as always
Disc break rotors make great little forges IMO.
Absolutely brilliant work,one day -------
Very impressive!!! Great work!!
Much respect.
WHY am i fascinated by this?
That is why I do it because it is fascinating.
You keep making 'em - I'll keep watching 'em. Thank you & greetings from South Africa
Because to be human is to apply a rich consciousness to causing change in the world. The change can be anything. It can be picking up a candy wrapper or washing the dishes or holding a baby. Some changes are that simple, other changes are a matter of deep vision and the disciplined dance of step-by-step action.
I don't have any of the tools this man has. Hell, I don't even know where the hammer is, but watching him do that work made me want to sun out and cast something for which I have no use whatsoever.
I get your fascination.
Mate, that's a serious backyard furnace.
Vaporize a snag in 2 seconds i rekon.
Thatvthing sounded like the interceptor firing up the for the first time in " MAD MAX " !!!
You can also use old brake drums too.
Yes.
truck brake drums especially, 100+lb each
Hey maybe a suggestion that could help you do less work for the cast iron from the discs. My suggestion is go to your local automotive shop that cuts rotors and this could be a autoparts store or a repair garage that cuts rotors. They always have cut waste from the rotors they will gladly give you for free, heck I would have given you small buckets due to the weight when you discard the waste cast chips. I also think it would melt faster than a solid would. Best regards.
nice work
Any shop that has a brake lathe will also have 5 gallon buckets of cast filings!
Cool thanks for the tips. We're do buy the stuff you mix in to the cAst.
Important tip - whenever using graphite powder, you should ALWAYS do it in somebody else’s shop.
Very cool, thanks mate
