Have seen a lot of these casting videos streaming on youtube as a background diversion. Yours is the first one I've seen in a long time that actually employs hydrogen degassing, a drossing flux and thermocouple temp measurement, so much respect for that! Adding a bit of filtration in the gating system (fiberglass screen or ceramic foam filter) would also help keep that clean metal cleaner. For all those aspiring foundry folks looking to up their game I'd recommend the works of John Campbell and the American Foundry Society. I work in the aerospace industry in the aluminum casting supply chain.
forgotten in public schools all over the world are shops-where kids learned how to make things. All they teach kids today is to buy things. Your hobby is an art, worth it's weight in gold.
Sadly, I disagree....people that are willing to pay for a true craftsman are very hard to find. If a hack charges less, that is where the money goes, especially if they are a smooth talker.
He didn't say anything about that Tim S. He was merely remarking that very few people these days know how to do, make or mend anything. That they know no different than to go out and buy things. There was no mention that they bought the things off of craftsmen.
Though I do tend to agree. Craftsmanship is becoming a thing of the past, few people can afford the services of a true craftsman. Equally, things move on change and improve, this is simply natural progress. Though we are definitely letting it go too quickly and readily.
I think his main point was, that we no longer teach anything remotely like practical hands on skills any longer. Certainly NOT in the way I remember we used to do, And it seems as if Mr Saunders also does.
@@tims4768 Yes BUT TIM that is the sad part about this!! In my day like in this video as a kid I was taught how to use my hands to MAKE THINGS!! True craftsman as you said ARE HARDER TO FIND because schools no longer teach "trade skills"!! So Tim Saunders IS CORRECT becuase kids today are NOT BEING TAUGHT ANY ACTUAL SKILLS the are now taught to "consume, waste and throw away" and that nothing has any real "value"!!! It has killed the art of "trade skills" or "craftsmanship" as folks like myself once learned!!
And looking at my grand kids I have a step grandson who watched me take old salvaged lumber and built a bench, a table and a whole DECK out of the wood I was given as "junk". But my step grand son kept telling me "You built a CRAP table!" with the joke to him being "scrap wood"!! He thought it was funny to keep telling me the table was "crap" but at the same time it saved me a ton of money and even made me money as I got paid to built the deck out of the salvage lumber I had left over from the whole load I was given for free!!! And my same step grand son was too stupid to realize I earned myself $80 for a deck I would have got nothing for had I just took it all to the garbage and PAID $90 to get rid of it as a load of trash!!! BUT you can't explain that to kids these days, because they think people just HAND YOU MONEY like it is their job to pay you for nothing!! And the real slap in the face is that his own father (who is my step daughter's husband) couldn't build a dog house out of BRAND NEW WOOD!!!! I know this as FACT because I watched my step grand son's father waste almost $150 in lumber to chop it up into firewood after he failed to build a dog house out of the wood he bought!! Showing me my step grand son has NO APPRECIATION for actual "skills" or craftsmanship and as for the bench, table and deck I built out of "scrap wood" (salvaged lumber) here today in October of 2019 I still have the stuff I build out of that lumber! The deck I made out of the same stuff is STILL on my neighbors house now 10 years after I built it, the bench and table I made for myself I use every day in the summer and sits outside year round in New York Winters!! So he can call my stuff "CRAP" all he wants.......when I built it I knew what the hell I was doing....and it lastly because I used skills he will never have!!!
ive never heard of such shops
@@gregbenwell6173 The whole point of a "public education" these days is to turn out stupid Democrats (or liberals in the UK). That way, they will always be dependent of the government.
Hello Myfordboy! My father was a Brass Moulder and made ship propelers in yoker glasgow at bulls metal foundry bull dale st Yoker.
My grandfather was the same and my father was my grandfather's apprentice. However even although the trade was taught to me over the breakfast Table! I later cast a bronze propeler for a small boat in my back yard which an 1950 was a pre war prefab. however I have now been watching your videos and I find them very educational!. I now have my furnace a stainless steel beer barrel just the firebrick to put in. I have my aluminum saved and it is in a very large barrel. so later in the month I hope to make a few cleats for my boat.
I will then post the video of my work on utube. thanks for all the informative videos just great stuff so at 70 I have a new hobby. cheers. tom copland in ayr scotland.
You should get some good castings as it's in your blood!
I've been watching you for quite some time. I am amazed that you are able to accomplish work like this on your knees!?
I'm up in age, and very active, but I could only tolerate a few minutes on my knees bending over, working on a concrete floor. I offer my respect and withhold my jealousy. 😂
Greatly enjoy your channel! Thank you for putting this knowledge out here.
I spent a lot of my working life as an electrician on my knees. My trousers have built on knee pads and are comfortable to kneel on.
Your videos area joy to watch! I love the way your processes have developed over the years.
I'm a mechanical engineer, I worked for Hamilton Jet in NZ for 8 years. We ran two large, sand casting aluminium foundries where I spent a lot of time doing installations and upgrades.
Watching you work brings back memories of the various processes required to make good castings.
One little observation which may be of interest to you - We never put bare metal steel tools into the liquid aluminium, they were always coated with a thick green 'paint', this was to prevent iron from dissolving into the melt and reducing it's tensile strength. The tools were also always preheated to drive off surface moisture to avoid adding traces of water and hence additional hydrogen into the melt. Sorry, I can't recall the name of the green paint, it needed to be reapplied regularly. Regards Paul
I think it's a ceramic coating that's baked on.
The 3D printer is coming in handy now. I guess that pattern makers may be loosing work in the industry soon. Love the lesson. Please keep them coming. You teach so much with out saying much. That is a gift.
There aren't many real journeyman or master patter makers left. I started in a pattern shop in June of 1974, at that time there were 13 pattern makers, 6 apprentices, and a bunch of us riggers and helpers. The foundry I worked at was the last large one in the area, and It finally closed in March of 2003. At that time there were three pattern makers and 4 riggers. I suspect at least 90% of the patter making capacity has disappeared from the USA since 1981.
@MichaelKingsfordGray-- Most of the losses we've seen have been due to foundry closures. I do still have some friends that have small pattern shops, but nothing like 40 years ago. I do have a friend that runs a foundry that is producing patterns with CNC machinery. They still have a couple of pattern makers to do the fine tuning.
Thorough, methodical, and fascinating. Thanks for sharing your knowledge, tips, and techniques.
Did You clean or wash
the sand by water
@@Hbtom21Yohannes Not sure if you meant to ask me, or MyFordBoy, but if you watch from 4:30-6:00, you'll get an idea of his sand processing technique. First he sieves it to remove or breakdown clumps, then he spreads it out fairly evenly, applies some water with a mister, and checks it for the right consistency.
One of the most underrated channel for casting thanks for the knowledge!!
man.. you made it looks easy..
what I like most is your way to turn papers and woods into something amazing
I am so intrigued by this. I do almost everything now, and metallurgy and casting is honestly the last thing besides chemistry I want to learn. I have my own bridgeport and lathe and do all of my own head repairs and just bought a boring bar to do blocks. There's so many projects where I need a aluminum side cover for my restoration, and the pull start covers for 3 wheelers are a couple hundred bucks. I have plenty of aluminum and recently built a foundry for smelting, and I get to use up all of my old oil. Free heat! Thanks for the video. I'm going to watch a lot more as this is my first. I watched others, but your attention to detail is how I am. Still have to research the co2 that you used.
The natural movements of a person that has done it a million times.
It’s all in the wrist a brick layer told me.
Your sifting machine is sweet! Kudos, brother!
Beautiful molds and mold making. The way you mull the sand is quite inventive. It's kill my back. I cast most cast iron and built a mullet. It's really sweet but literally took 4x as long as I thought. Still, muller's are awesome!
I love the skill you show. Quick, precise, no stupid mistakes.
I'd make a muller but I don't have room for it.
Very good video. Most people don't know the amount of work involved in making a set of these castings. I've been working on the set you sent me. I have the cylinders completed. These are top quality castings at a fair price.
Lonnie
The reciprocating saw contraption alone got my thumbs up, the rest is just fabulos.
Not only was it wonderful to watch your work, but what could be a more noble reason to cast than for that lovely engine?
Excellent video: Great on melt prep.. I worked in aluminum flat rolling for 18 years and know the process from casting rolling ingots and cast sheet through finish and pack. Quality begins in the cast house.
That's an awesome shaker contraption. I now have the desire to build my own.
I agree that is one creative vibration setup!
I'm amazed how you make foundry work so easy. Another great video, thank you.
Great job of tempering the sand, experience shows how nicely the finished casting came out, I am very impressed, cheers!
You have amazing skill and a great deal of experience. Loving your channel. Impeccable workmanship
Ох! Я прошу прощения за первый отзыв. Вы очень крутой специалист. Я восхищён. Превосходное литьё!
Your sifting setup is awesome
el mejor blog de internet sobre como fundir aluminio y fabricar los moldes ,sin secretos y sin mezquindad, realmente un maestro
Best aluminum casting TH-cam channel 👍.
Totally agree with you, this guy has done it all, and looking at his blog too is just super informative pop, when I have completed my current jobs then I will buy the materials and make some casting work for my American van, between the videos and the blogs it must save lots of time and expense, by doing it right first time. Thank you so very much in advance....phil
Did this in shop class in 8th grade. Took a nice schrade knife blade and cast a cool aluminum handle on it. It was cool enough that some one stole it from me 40 yrs ago.
Sir Mark of a true tradesmen. You made that look so easy!
Love your silent videos, great work as always. GREAT CHANNEL
are you deaf ?? you can hear crows from time to time, and the continual swish of traffic...……………….
Yeah, I can hear the pleasant sound of work getting done. It is great!
That’s a genius way of filtering the sand!
now thats the most ingenious sand sifter i have ever seen !!
Man that sifter is so cool. I wish I could double thumbs up this.
What an art form. I can understand mass production, but for a couple of pieces? Thats crazy!
As always another thumbs up from my side.
Just keep uploading ,we are always there to encourage you 🤗🤗🤗🤗🤗
Good video explained very effectively....good job done.
Das Sieb ist das Geilste Ding das ich jemals gesehen habe 👍 tolles Video
Those grooves inside the box make so much sense
Love this video. Especially the screening of used sand using an old reciprocal saw. I've been looking for good videos to have my students watch in my casting unit. thanks
O my god it's fantastic video
It's help me a lot for practicle purpose
I love your videos. So informative and concise, no endless comments. Just knowledge!!!
you deserve 10 million subscribers.
Nice video for students
It will help them to read about casting process and method
Love the power sieve! So simple and effective.
Now you know you can't de-gas with Sodium Carbonate, or so THEY say. LOLOL You always have such nice moulded parts, for using a system THEY say won't work. LOL Always like to watch you through the moulding process. You make it look simple. You do great work!
Mature, If you are happy with that mistaken belief so be it, but as one of the THEY may I point out that bubbling water vapour through molten aluminium can not possibly degas it. In fact by the reaction of the aluminium with the vapour it INCREASES the hydrogen level in the metal... Dave
Dave, are you a chemist?
Could you supply a few equations to support your comments.
Thanks.
Roy, Yes, I could supply several equations plus supporting evidence from the Ellingham diagram. However, and please do not think that this is a cop out (even if it does sound like one), The explanation is a bit longwinded and in part technically complex. But, and here is why I am holding back, I have heard a rumour that there will soon be a video out there that goes into this question in considerable detail and that it will finally put the nail in the coffin of any suggestion that washing soda degassing works. For the moment can I suggest that you do as I did quite some time ago and look into the chemical and physical properties of the various Sodium carbonates that are out there. To my knowledge there are 4 varieties although there are possibly/probably a few more. However only two are common - the anhydrous version and the decahydrate (the latter is the traditional "washing soda") Following through and understanding how these two behave as the temperature is increased to degassing temperature and above is the crux of the issue.
However it is fair to point out that a little gas is sometimes a decided advantage in some castings. Dave
@@alterego4218 Then could you please explain how MYFORDBOY has such great castings??
Mature Patriot, At the resolutions available on YT it is not possible to see if it is a good casting or not particularly with respect to gas content. Surface appearance has little to do with gas. Dave
Your "inventive'ness" is only surpassed by your "casty'ness" (you know what I mean:). "A treat for the eyes and a joy that will last forever". Cheers from So.Ca.USA 3rd House On the Left (please call before stopping by)
so nice to see the finished casting used in your engine, love it,
Congratulations. Wonderful work. (Bill from Brazil)
Very relaxing to watch. Almost like Bob Ross painting, that’s a good thing.
Rotating flame in the furnace mesmerizes 👍
you do nice work! i worked for walton foundry years ago. 1963-65, i think!. cast iron foundry, about the same with the moulds, tho.
we used form that a crane lifted them. some weighed more than a ton for the big castings for the oil field pumps. nice, work. be safe!
From a pure comfort point of view, and to protect your knees! why don't you have a mould making table? I cringe every time I see you on your knees on that cold hard garage floor!
Trabajo excelente, muy bien explicado.
Your improvised electric sifter is truly inspirational! First class video as usual. :)
After WW3 you will survive whilst being able to make everything with about nothing. respect!
Laughed my ass off while seeing you using a recipro for a completely different job, well done!
New subscribed from Somalia thanks my teacher
THE BEST VIDEOS!
I really enjoy seeing home casting ideas. I have a thought: is it better to sandcast or cnc mill?
Hmm🤔
You are really ingenious, better than McGyver! 👍🏻👍🏻👍🏻
Merci beaucoup pour le partage de votre maitrise technique (Thank you very much for sharing your technical mastery)
always interesting to watch the process of a craftsman.
Very nice. Straight to the point. Make a vid for casting a V8 block...if you ever get a chance. Thanks
Never seen such CLEAR and COMPLETE processing. Spellbound :)
That core mold is genius.
MACGYVER HAS GOT NOTHING ON THIS GUY...WORK WITH WHAT YOU HAVE. THIS GUY IS THE MASTER...
Great job.
I enjoy watching your videos
With this skills you can build a factory.
It one of my biggest priorities
amazing technique 🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍
Love the ingenious sand sieve brilliant idea , very entertaining and informative thank you .
Perfect cure for my Myfordboy withdrawal symptoms, need more casting vid's sir!
Yammy ! Pop's freshly baked engine block !
At 10.38 it looks like a death ray gun. Awsome work/passion
Great video and understood the process nice and simple, obviously takes practice as i screw up a lot...although guess like my forge that runs on coal, been wanting to go gas for couple years but can't afford a bottle of gas (first world problem)
Its why we need more people teaching real skills like this man, least then some of us might survive a new world order
I really dig the reciprocating saw sand sifter.
Very precise and smart. Con gratulations sir.
Love the step by step video format.
Why are your casts so perfect 👌
Practice.
Briliant shaker. great video, thank you.
I have an idea for you... You should metal cast a bunch of parts to make a robotic arm. There are some 3d printable models out there you could use as the casting model.
love the sabre shaker
Greetings from Tunisia .thank you for the detailed processes. GOD bless you
I think you addressed everything in the process, which should eliminate the usual questions. Now to cruise the comments & see who wasn't paying attention.
FASCINATING!!!!!!!! That was educational 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼
Now this guy is resourceful, love the use of the saws all. As always, excellent results.
Thank you for your sharing. Very good sand casting process video, i learnt more from your video.
Excellent video MB
One very much has the sense that you know what you are doing!
Your sieve is just so genius
Always a treat, to see another one of your videos. Cheers
Informative. I had long suspected that the green-sand was not prepared by magical elves.
Well I worked in a foundry many years ago and I know I would never think of those guys as elves but they sure we're magical when it came to their experience. I was just a young kid!
Wouldn't oil have been better than water? Water puts off a lot of steam and could cause blow out. Right? Just asking. Good video. Thank you for your time in the production of these casting docs.
This is water bonded sand. Oil will spoil it.
Pure art! Congratulations!
this is sooo good. thank you very much for sharing!
Awesome job sir... clearly understood..👌👌
This video is awesome!
That sifting rig really cracks me up. Although it works just fine. Just seems a little Rube Goldberg.
if it's stupid but it works, it ain't stupid :D
Great job!
I always admire how you work!
Brilliant video
Nicely done. Enjoyed.
really nice casting as always. a little in awe.
Great video, very helpful. Many thanks
Ok, the sifting machine is genius.
your screed is very clever
