I love that vintage look of your video's but with modern editing techniques. Wasn't sure if I was looking at footage of the late 80's/ early 90's or something shot in 2019. Very educational, I like it.
Nice video. I always enjoy your forensics. Learning what happens when you make choices is the most valuable part of your videos. Thanks for taking the time to make this video. Mark
That's really interesting! I like the smooth surface finish on the petrobond, but I agree the coal dust sand looks nicer. Here I thought the petrobond couldn't handle iron temps. I get the same flames from bronze castings with the stuff.
IIRC, petrobond can indeed handle cast-iron temperatures. Once. I hope to be corrected by folks with practical experience, but I believe Cu alloys just burn the oil out of petrobond, and the whole sand (even the “burned” black bits) can be reused, though eventually you need to add more oil. In contrast, iron temperatures will actually damage the petroclay adjacent to the casting.
Congrats on 15K subscribers! I use Petrobond with aluminum with great success. No cast iron "yet"! Thanks for all your words of wisdom.. Fred Ontario, NY
Like the raw texture look of the Petrobond.. Looks like a lot of old Iron pieces I have seen in the past.. Congrats on catching the interest of 15,000!!
Hi I have been watching your videos for some months now and learned a lot thank's Tom Copland Ayr Scotland. I am just building my furnace at the moment and I will have it ready for next week.
Another usefull video Luckygen nice flywheel pattern & subsequent casting from it, coaldust has allways been used for iron castings in the foundries over here in the uk as you will know,I make patterns & cast name/house plaques in alloy & brass also miniature railway & traction engine name plates in brass & traction engine number plates in alloy,I sieve a coating of petrobond over the pattern then back up with Mansfield red [greensand] apart from getting a good finish petrobond is expensive,when I shake out I try not to mix the sands together,as you say it loses its bond I add a little "hybond 100"bentonite now and then,it's produced locally for the foundry industry. keep up the good work Merry Christmas I'm over in ozz at my daughters for Christmas taking in the great weather in W A .Regards Graham.
Congratulations on reaching 15,000 subscribers! I've only been a subscriber for about four months and i really like your scientific take on your results. I've learnt SO much from your vids, I've given you a little shout out on my "Home Foundry Build PART ONE Video" so maybe a couple of my portrait watching subscribers might come across to your superb channel. Have a great chrimbo from us in the UK. PS i liked the look of the coal dust one best, and that fly wheel was beautiful :)
Lots of good practical information in here. Great presentation and congratulations on 15k and counting! Are you or have you added nickel and copper to your castings to give it more strength and less brittle for certain items?
@@luckygen1001 kuul! I've read 3 to 5 % nickel and 1% copper mixed in makes a really tough and less brittle cast iron. Planning on using this mix to make the waist and bottom of a big anvil 5.5. Inch thick top plate cast to it then welded all around w nickel55 rods. Cheers and a blessed Christ Mass and seasons greetings sirSir, Crawford out
Hi, congratulation for your 15 K that i will be a forever member. Have a nice Christmas and good health for the next year. That's all we need. Very best regards
Do you have any experience with mould coatings? I have seen some factory videos and they use some kind of coatings on sand moulds. I am thinking of making my own coating by mixing sodium silicate and graphite and thinning it with water.
I think I like the rougher texture of the coal dust rather than the dull smooth texture of the petrobond. Cast iron castings have always had that rougher texture and it makes it look true to being cast iron, the smoother texture is usually for bronze imo, and just doesnt look right. I was about to yell at the screen when you cut into the flywheel and destroyed it...
Petrobond sand did not give a smooth surface all over so looks strange. Also I agree cast iron needs to have that rough texture to look like older castings. You need to sacrifice a casting now and then to produce better castings in the future.
Congratulations on the 15.000 subscribers! What a sin to break the beautiful flywheel, but it shows a perfect casting and, anyway, you can cast another when you want :-) Very interesting model steam engine. Did you design it yourself?
You were the only person that commented on that engine. This one is my personal favourite of all I have built. All my videos about model steam engines do not attract many views. It is not a popular subject on youtube. If you have the time look at my very early videos and you will see model steam engine videos.
The coal dust versions-I assume that’s regular bentonite greensand behind it? And the facing sand-are you using coal dust as parting powder, or is the facing sand just greensand with finer sand, and mixed with coal dust?
I like both castings the one question that I have then you say coaldust sand are you mixing actual coal dust in with your Bentonite sand mixture and can you tell me the ratio of bentonite clay to sand to coal mixture
I have never bothered to see what the pressure is. I use a vacuum cleaner as a blower and adjust the regulator to suit the output of the vac blower. I aim for a neutral flame coming out of the exhaust vent. Why don't you have a go at melting cast iron? I get so many home casters complaining that I am the only one that pours iron castings on youtube.
@@luckygen1001 , That's a future plan, to pour Iron that is. The next time you use the acetylene gage please take a peek at the working pressure and leave a message on one of my videos. Thanks.
Luckygen: I made a well built furnace with an inside diameter of 8” by 16” high. I’m interested in pouring cast iron, after fooling around with aluminum and brass. What is your opinion for a crucible? Can I make one myself or should I buy one? Best regards. D. Alexander.
Silicon carbide graphite? (And, please know I’ve been employed by Indiana State DNR as a blacksmith/woodwright, and have considerable copper, silver and tinsmith experience. In retirement I want to pour bronze and cast iron.) Thank you for your response. D
good day sir first of all, I want to thank you for the knowledge you share on youtube I'm just going to produce my first form from greensand, let me get inspired by your information, but I wanted to know when to make a green sand mold, how and how long it will be necessary to dry, or do you pour into the mold as soon as you finish it? I am afraid of you, and thank you for the answer sorry for my English
Hello sir ,i am practicing greensand molding process for castiron metal and i am facing surface finish issue what should i use for better surface finish grephite powder or coal dust on mold surface??
Hi luckygen1001 a big well done on reaching 15,000 subscribers, no easy task for a Maker channel particularly one focused on casting. I do however note the presence in the comments section of the Usual Suspects from the You Tube casting community and that says a lot about the quality of your videos for your investigation of casting mythology and bad habit proliferation. Again, well done and a Merry Christmas and Happy New Year to you and your family. Mark
I disagree about the 16:9. 5:4 is great for framing objects for technical demonstration. Higher resolution never hurts though, but it does cost more in cameras and in editing and uploading time.
@@luckygen1001 , interesting peice ot information. Thru the camera to the untrained eye they pretty much look straight so the taper is not alot or it would be more conical than straight. I think I said that right lol
luckygen1001 : I've watched all your videos because I'm interested in casting iron. I've had no training except watch Sandrammer's, Olfoundryman, and MrPete222 but they only do Aluminum. Thank you for what you've taught me and Merry Christmas.
I like the texture of the petrobond casting, but I can see why you would not want it on something that was not ornamental. Gaaaaaaaa you cut up that beautiful flywheel! 😲 nooooooooooooo!
Sadly we live in the age of 'political correctness' , with far too much emphasis on 'glitz & glam - just my 2 cents . Great work as always , congrats from a long time subscriber !
I nearly cried when you broke that lovely looking flywheel... Martin
You're not the only one Martin.
Ooh Martin I gave you a little shout out too in my “home foundry build part one” video, you guys are so awesome.
Sacrificed in the name of casting improvement.
I understand, but it was still sad to see such a good useable casting get destroyed... Martin
I was just about to say that. I would've donated real money to rent some kind of x-ray to see inside instead of witnessing such a tragedy.
I love that vintage look of your video's but with modern editing techniques. Wasn't sure if I was looking at footage of the late 80's/ early 90's or something shot in 2019. Very educational, I like it.

Yes it is the forensic evidence based methodology that makes his videos unique
You're the best hobbyist metalcaster I've seen on youtube. Subscribed.
Thanks for the demonstration with petrobon.

(Yes, that was a Maxim 11 reference: “Everything is air-droppable at least once.”)
Ever catch the video of an Airborne Exercise where the ' chutes' failed to open properly for a couple of Humvees.
Airdroppable Only Once
Roger That.
Gorgeous castings!
Thank you for sharing your knowledge! Learnt a lot, will be putting it to good use soon :)
Had a hunch that if I looked at your channel I might find something on this. Always good information, thank you.
Sand does not last forever, after a long time there will be blowholes and washouts.
Very impressive ! Love watch your videos, such a good source of learning.
Keep it up !

idk, I always thought Petrobond was sort of ok for anything but if you specifically pour this metal or that, there are better choices
How could anyone dislike this video? This is artisan work, very interesting stuff.
Dead heads with no clue what's coming.
So on the third one, you just poured it into the fill hole and not at all into the risers? Was hard to tell
Hey mate another Aussie caster here just wondering where you got your metal casting frames
If you mean my molding boxes I make them as I need them.
Congratulations!
that is a lovely little flywheel engine
Oh man, I would like to see people's expressions when he broke that flywheel! Priceless! LMAO!
I am voting for coal dust. Thanks for filming

Do you have any experience with mould coatings? I have seen some factory videos and they use some kind of coatings on sand moulds. I am thinking of making my own coating by mixing sodium silicate and graphite and thinning it with water.
I used them a long time ago to coat S.S. molds. and they work really well. So now I do not need them because I use coal dust with my green sand.

Very interesting model steam engine. Did you design it yourself?
I found a very simple line drawing at a website and then had to make all the drawings so the engine will run.
@@luckygen1001 Thanks! You did a superb job! Beautiful and unusual engine. Possibly deserves a bit more of video time :-)

The coal dust versions-I assume that’s regular bentonite greensand behind it? And the facing sand-are you using coal dust as parting powder, or is the facing sand just greensand with finer sand, and mixed with coal dust?
Facing sand has 4% coal dust in it.
I like both castings the one question that I have then you say coaldust sand are you mixing actual coal dust in with your Bentonite sand mixture and can you tell me the ratio of bentonite clay to sand to coal mixture
Bentonite 7.5% coal dust 4% by weight.
Thanks for a most interesting video. won't be long and you will be doing a 30
000 subscriber plaque. best regards from John Spargo in Cape Town
wow, impressive
could you weld the flywheel back together by autogenous welding as a project ? with reference to keith ruckers drill table problems
Yes you could reweld the flywheel but for me it was only a test piece for destruction to see if my casting standards are any good.
When you're set up to use an Acetylene gauge on a propane tank, what is your working pressure set at?
I have never bothered to see what the pressure is. I use a vacuum cleaner as a blower and adjust the regulator to suit the output of the vac blower.

Bentonite and coal are added to this material, right?
Yes.
Is it possible to mix petro sand and coal dust sand and get the benifits of both?
You could try it but mixing a oil based sand with a water based sand will have problems in the future.
cool

Seasons greetings for you and your son and may next year be the best ever.
Another great video. 👍
Does the quality of the embossing change if it is facing up or down?
I have only cast it facing down but I should try it facing up one time to see if the quality changes.
Coal dust is dirty filthy stuff to work with however. I think the petrobond one looks better :)
Any interest in doing a centrifugal casting?
Not really, mainly because it is for very small parts.
15,000, shoooot. I have 6. Mum, Dad, 2 brothers and both me billy lids.
If Bronze is for 10K subs, is Cast Iron the new standard for 15K subs? Good on you!
Your videos are awesome, but they could improve a lot with a better resolution and a 16:9 ratio
I disagree about the 16:9. 5:4 is great for framing objects for technical demonstration. Higher resolution never hurts though, but it does cost more in cameras and in editing and uploading time.
Yes you are sooo right. Not every one can afford the latest and greatest in cameras and software.
wow gee id love too have a cuppa and pick youre mind
How long does it take to melt the iron?
I seem to recall at least one video where it was timed with a large school type clock in the background
50 minutes.
What are your thoughts on using tapper sprues with cast iron?
I only use tapered sprues with any metal I pour. don't use straight sided sprues as they will suck in air.
luckygen1001 : Sorry the camera angle made it look straight so I was wondering.
@@luckygen1001 , interesting peice ot information. Thru the camera to the untrained eye they pretty much look straight so the taper is not alot or it would be more conical than straight. I think I said that right lol

Coal dust sand over petrabond
ASMAT ULLAH 1 UA-cam CHANNEL
;( Casting was perfect and you broke it!!! Wanton destruction!
Well, i guess you will make a new one.
A tip for the young players - "Petrobond" sand *cannot* be made by soaking normal sand with petrol. Don't try it.
Wow that is playing with fire!
Bugger....Now I'll have to throw out that 50kgs of sand I have just prepared....
Congratulations!
