That definition is outstanding. I just mixed a batch of Kbond sand but I used the play sand from Bunnings. It seems to be way finer than the previous batch of white beach sand that I had used for my greensand.
Good to see another foundryman watching my videos. I had a look at your videos and had to look at a map to see where you were. I did visit a foundry in I think was in Henderson It was called Alucraft. They made aluminium garden furniture. I have never seen a arc furnace running and heard that they can be very noisy.
@Luckygen I enjoy your videos and I am really impressed with you being able to do cast iron, not an easy task at all. That old arc furnace was decommissioned earlier this year. We replaced it with another induction furnace. The old girl's power consumption was just too high.
Instead of getting scrap metal price at your yard you could get a lot more by making signs for your shop. I am sure that a "The Ultimate Recycler" sign would sell very well!
Absolutely amazing work. You had me engaged from the start to the very end. Lots of people casting aluminium on CZcams, but you’ve 1 upped them all by doing cast. Awesome stuff 👍🍻
Another great casting video, Ironman, VTsteam here. Question: is your facing sand the same or finer sieve than the backing sand? I remember you used quarry sand for your main greensand, but never heard in the videos whether the facing sand was the same coarseness, or not. Down below here in another comment you mention pool filter sand -- haven't heard you mention that before. Is that for facing sand? Thanks for the clarification, and keep up the great work!
Good to hear from you again VTsteam. The sand I have always used from that quarry has always been swimming pool filter sand. It is the finest sand grain they have after going through their sieves. Their sieving is not perfect so I run that sand through a sieve which I can poke a 0.5mm wire through the mesh. My facing sand is the same as my backing sand with one tiny difference, my facing sand has coal dust in it. My backing sand has no coal dust in it from the start but what happens it turns light gray from the burnt and unburnt coal dust in it. In the beginning I never used facing sand and after a melt of cast iron I would add some coal dust and bentonite. The problem with that is it is hard to know how much coal dust and bentonite are burnt after a melt so I was adding too much, so I was replacing my sand every year or so. So now I used a facing sand which has fresh coal dust and bentonite and it keeps the backing sand fresh. I have never replaced that sand in ten years. I hope this clears things up.
Thank you kindly I-M, now I understand. I'm casting iron again after a long pause, and have relined the furnace your way. 20 minute pours from cold for 6 - 9 pounds in an A6. Cement cores. Have tried a couple types of sawdust, and commented on what I've found. Stop by madmodder some time if you get a chance. Best wishes!
I always add ferrosilicon and use no flux so in this video I left that part out and showed what the inside the furnace looks like when the iron is melting.
have you ever cast any aluminium moulds for casting fishing sinkers cos i am trying to get my head around the best way to do it . either that or i might have to try and make them on the mill not sure which would be the best way to do either .
Great job and great pour on that big long flat sign. Loved how it filled out so well. Is coal dust recommended for metals other than iron, eg brass, bronze or copper?
Thank you Luckygen. I was wondering what percent coal dust would you use if had 7-10% bentonite? Also, that pciker upper tool you have used at 11:00 I was trying to get some clues as to the clamping mechanism but not quite enough detail in the video. It would be great if you could show a closeup of that some time, or sell some plans. I'd be into that.
Are the 7-8% bentonite in the greensand mixture measured by weight or by volume? I found mine does not seem to get the desired strength so I added by feel. It ended up being way more. Does anyone have some resources (books, papers, CZcams channels) where I can find more details about moulding materials? :)
It always amazes me on how fluid Iron flows when you pour cast Iron. Good Job!
Good to see you're still above ground.
I really like your pour dolly. It makes the pour stable and safer.
Yes you are right it makes pouring a lot safer but the reason why I built it is I suffer from back pain and it takes the weight from my back.
That definition is outstanding. I just mixed a batch of Kbond sand but I used the play sand from Bunnings. It seems to be way finer than the previous batch of white beach sand that I had used for my greensand.
I have been using mortar sand and bentonite it's quite fine.
I use swimming pool filter sand.
Enjoyed your work. Thanks for the look.
Nice work, sir. Curious what you charge to make a sign like that.
Me too! :D
Johnson repair & care?
Good series.
An obscene amount of money! I was wondering when are you going melt cast iron in your big furnace?
i miss you sir glade your back
Thank you.
That sign has been kept secret! LOL
Good video mate, I always enjoy your videos and good explanations. Keep em coming, looking forward to the next video, greetings from across the ditch.

Excellent job Lucky! Now I what to get into casting!! 🙄🤣

@@luckygen1001 Yes! I'd certainly be keen to do aluminium at least! I'd love to resell people's grotty old saucepans back to them in a different form!
Fantastic results
Great work!
Another great vid.... Thanks.....

Yeah. He inspired me to make cast iron castings and it's amazing
Thank you for watching the video.
Thanks for sharing 👍
Great work/skill again, is there any info on your burner set up. Thank you
Just look at my older videos, I have two videos on burners.
Really turned out nice, great work.
Flamin Crows!
Very good
Great video very informative! What mesh/micron is your sand i have been battling with mine and it seems really course.
The sieve I put the sand through a 0.5 mm wire can be pushed through so my sand would be considered coarse.
@@luckygen1001 Thanks for replying. One more question where do you get your coal dust?
Profi!!!
Thanks again for such a thoughtful video. What are you using for your oil tank, and do you keep it pressurized?
The oil tank is a 45 kg propane cylinder and is pressurized with compressed air.

@@SRHacksaw I'm not a member but I'm following your ELS project. I hope you can make it.
Did you use any ferrosilicon in the melt? It looked like you just melted the rotors and poured. No flux, no ferrosilicon?
I always add ferrosilicon and use no flux so in this video I left that part out and showed what the inside the furnace looks like when the iron is melting.
@@luckygen1001 okay. I figured as much. Nice work!

@Toreutics thankyou for that👍👍👍
I have heard that other casters use coal dust with bronze but I have never tried it.

It is a pair of tongs with half circle parts that grab the crucible.

By weight. All sands are not the same so you may have to adjust the amount of bentonite to suit your sand.
Liked!!
i was looking for that sock
nice thanks man
Will coal dust "hurt" an aluminium casting? I understand there are benefits for cast iron, but are there deficits for aluminium?
coal dust is only good for cast iron.
@@luckygen1001 thank you for responding.
Thankyou👍
How much kg of iron this crucible full charge
14 kgs
How much oil or diesel fuel was used for this one heat?
It ranges between 8 kg to 9 kg for one heat.
Top secret! must be A for ASIO
It could be.
