Ok thats brilliant. I could never figure out what a pattern box for a propeller would look like I figured it would be very complicated due to the parting line issue being three-dimensional. I was confused until the very end and then it suddenly made perfect sense. Bravo sir, very ingenious. The internet was made for things like this and people like you.
It takes a lot of study to understand how the parting line works on a propeller. If you want to have a look at the parting line on the fans you use on a hot summers day, they are still there after manufacturing.
That is quite an impressive mold there. As i first started watching i was trying to think of how i would accomplish it, and i was way off the mark. Glad to see someone passing on some great knowledge to others. Keep the videos coming Mark
The first time I saw this was a year ago and I was really confused on the third piece or cheek in the flask. Now that Ive actually rammed and poured a hundred times since then, I now understand why you gated it like that. It makes perfect sense to me now, thanks for sharing
A very very special craft all of its own And I can see it taking a lot of tries to reach one's expectations of a great piece of work. Well presented. Thanks .
I don't have any hands on experience with this but from watching a lot of experienced guys do this, they recommend to use a wedge type mallet when compacting the sand for intricate areas. They say the wedge also forces the sand to move and fill in sideways to get under parts and into crevices where it normally wouldn't if you just compact it from the top.
estare al tanto, con ese proyecto, del hierro fundido, porque tengo en mente realizar un molde con este material, estaré muchisimo agradecido, MAESTRO.
Thank you sir ! I was wondering how to achieve the process and found your video...That said, it will require much skill if someone like me wants to do the same think!! 😅😅
Very informative video, What type of casting sand did you use here? I am really strugling to get the sand like the sand here. My sand does not hold shape as well.
How it works (the way I got it) 1.You put the propeller in the first pan 2. Pour on white stuff on one side so it does not stick with propeller. 3. Take the second pan and pour sand on it (this sticks with the sand on bottom sand to make on piece). 4. Do the same thing on the other side of th propeller. Expose the propereller and put white stuff on. 5. Put the 3rd pan on it and stick it with more stand. This sand stiches with the bottom sand and form one piece. 6. Now remove the other pand and remove the propeller carefully. Put back the other pan which creatas a mould. 7. Pour in molten iron. I still dont know why the iron pouring not damage the sand mould. My interpretation might not be correct but it is close.
luckygen1001 that is the trick! And it is a trick. Getting the right level of compaction without ramming too tight or loose and needing different levels of compaction in one mould takes many many practices to get right. So many techniques like flame scorching to graphite dusting etc.. just got to keep practicing!
Thanks for the great videos, About how long would it take to melt brass in your simple propane furnace, And did you make any more improvements to the propane torch,
Thanks, I will give my burner the boot and make the one you posted , It's takes 2hrs, to melt about 10 Kilos of brass with my present burner, Could you tell me where to buy the heat proof wool, And thanks again for sharing your knowledge,

It's always interesting to see a expert at work . He makes it look so easy , when of course it is not !

That is really impressive. I am a novice sand caster and you done something really amazing. Excellent job sir.
Thank you for watching, will you try to melt cast iron next?
@@luckygen1001 I currently do not have any cast iron in my metal pile. I will look around and see what I can find so I can.

Nice work, casting a propeller is a little tricky !
Bravo sir, Bravo. That is the first 3D type mold I've seen yet. Nice outcome. Thumbs Up for sure!

Obrigado amigo.Isso me ajudou muito.Parabéns por compartilhar seus conhecimentos de uma forma clara e didática.
Great video, I love to see foundry work. I am always amazed that you can do so much with sand and some metal scrap.
Wow! Sand casting to a whole new level! Thanks for the video!
Thanks for explaining the process that was a great teaching.
Thanks for putting up this video.
Really appreciate it 👌
Are you thinking of making your own propeller?
Keep the videos coming. I learned something new in this one! Thanks. Mark
♥.♥
Nice work on a hard pattern.
Nice technique to form the gate under the propeller.
Superb example of tricky mould making. Your work is very impressive. Keep up the great work!
I would like to see the prop finished.
Very informative video, What type of casting sand did you use here? I am really strugling to get the sand like the sand here. My sand does not hold shape as well.
OMC used the lost wax process to make their propellers when I worked there. I can see why.
Brilliant video!
Nice..👍👌
Was I the only person who clenched all muscles when he was splitting and putting the pieces together before casting?
I really enjoyed watching this clip. tks
Lucky Dube Thank you for watching.
That was pretty neat.
Is the propeller you cast slightly smaller due to heat shrinkage? Is there a way to avoid this?
Yes it is. The only way to avoid this is to make a pattern of the propeller slightly larger.
Thanks for the reply. Ok that shouldnt be a problem, I intend to do it using a 3D printed propeller in PLA to create the mould before melting it out
I still have the horseshoe I cast in the 9th grade 45 years ago
Which did you use sand?
Green sand.
@@luckygen1001 did you use bentonite
Mi pregunta es el material q ud ase el molde q es cemento con arena o es barro me puedes ayudar con el nombre del material amigo
Esta arena no tiene cemento, tiene arcilla y la arcilla es el aglomerante.
@@luckygen1001 y me puedes de sir a donde puedo con seguir esa harcilla aglumerante te agradesco x esa informacion amigo gracias
Pleqse Make a video about facing sand i am habing a big problem with my ruff casts
Como vc fa pra esta areia da um boa. E n desmanchar quando vasar o metal?
Eu uso bentonite para unir os grãos de areia juntos.
My dad did this in early 60s
im sorry what did you dust in the first box, that was going to make the molds separate? I quite missed that.
Talcum powder/baby powder.
potentially a stupid question, but why doesn't the sand fall out when you keep turning it over? I realize its packed in.
+antony wardle Because this sand does not obey the law of gravity.
+Improvised Weaponry Its green sand, something that I didn't realize at the time. ;-)
+CNCdoesMinecraft you're not funny.
will regular old sand work? i'm doing this for my rc boat.
Sand needs a binder to hold it's shape until the casting is pulled out of the sand.
tnk for this video....
good job
ما هيا مكونات رمل الذي تستعملة؟
طين البنتونيت هو مادة رابطة وغبار الفحم لإنهاء السطح بشكل جيد.
Muito bom
now i know thanks thumbs up
whats the powder sprayed in blw two layers of sand and y it is for...?
talke or baby powder :)
It’s so the molds separate
outstanding
How it works (the way I got it)
1.You put the propeller in the first pan

6. Now remove the other pand and remove the propeller carefully. Put back the other pan which creatas a mould.
7. Pour in molten iron.
I still dont know why the iron pouring not damage the sand mould. My interpretation might not be correct but it is close.
It was bronze not iron.
Take a bow! You made a tricky job look fairly easy,it is not! Had several goes to get a barely passable propellor. Tricky mould to get right.
The trick is to get the sand to behave.

😂😂😂
what kind of sand is used?
Please forward your answer to my email...
Thks...
A naturally bonded green sand that I purchased locally.
luckygen1001 no other mixes on your sand...?
Beacaue my sand always falling...
Sounds like it needs more clay to make the sand stronger.
luckygen1001 how much blend clay and green sand...?
7.5% clay 92.5% sand.
Had me wondering about that 3rd layer. :)
Thanks for the great videos, About how long would it take to melt brass in your simple propane furnace, And did you make any more improvements to the propane torch,
10 kilos of brass would take about 25 minutes. No I have not made anymore improvements to the propane torch. Thankyou for watching my videos.
Thanks, I will give my burner the boot and make the one you posted , It's takes 2hrs, to melt about 10 Kilos of brass with my present burner, Could you tell me where to buy the heat proof wool, And thanks again for sharing your knowledge,
Do you live in Australia?
Yes lucky,
