No beating around the bush, straight to t he point with useful information from real world experimentation. Thank you for another great video. The whole internet sees the King of Iron bested by some superglue. Thats a day to mark down on the calendar : )
A iron casting that size (13.5 Kg) takes about 6-8 hours to cool to room temperature. The first surface plate I left it in the mold for two days but to answer your question it makes no difference as this one was dug out of the sand as soon as it was room temperature.
Glad you asked! The protective screen is a square shaped piece of glass to shade the camera from the intense heat from the crucible. The glass was taken off and cleaned but when I put it back it was too far from from the camera. So what happens is the glass reflects like a mirror and makes a horrible picture. I was not happy when I reviewed the footage afterwards but now I know not to do it next time.
@@luckygen1001 One would think that gravity could help. Apparently not, it will shrink whichever way it is oriented. Thank you, this was a good lesson for me.
I'm always amazed at how long you can take between removing the metal from the furnace to actually pouring it. I'm curious, do you measure the temperature of the metal while its in the furnace or do you just know by color when it's ready? Nice solution to the shrinkage problem. I'll have to remember this one.
When you use a large crucible (A12) and have a furnace that always gets hot iron there is a lot of time before the iron gets too cold to pour. I do have a pyrometer that goes to iron pouring temperatures but do not use it because it gets in the way. When you have been melting iron as long as I have it is so easy to judge pouring temperature by seeing what the iron is doing and time taken after the last piece has been added. 10-15 minutes is plenty of time to super heat iron to pouring temperature.
@@luckygen1001 Thanks. I'm also curious about two other things. It appears, at least in this video, that you add metal to the crucible after the furnace is running. I assume you loaded the crucible with broken pieces of rotors and just added metal as the metal in the crucible melts. Is that the case? If its not the case, why? Also, approximately how long does it take for you to go from lighting to the furnace to removing the crucible. As I said, I'm just curious.
@@swdweeb Before I light the furnace the crucible is placed in the furnace and filled with broken pieces. The rest is added when the iron melts in the crucible. From lighting to removing the crucible takes 50-55 minutes to melt 14 kgs of iron.
@@luckygen1001 that's really faster than i would have guessed. Thanks for the schooling and all you do 🙏 Blessed day and well wishes Sir Crawford out ⚒️🧙♂️
I was hoping no one would ask that question. I went to a foundry closing down sale and purchased 10 of those ladles from a bidder who purchased a large amount of boxes of those ladles. So I have no idea who makes them, perhaps some one reading this could tell you where to buy them.

Yep superglue is great stuff.
Thanks for the great video! Always enjoy learning something new from your work!
Great stuff. Very interesting.
You have a nice way of explaining these super cool things! Thank you for all the videos!
Your a legend gen, hope we catch up again some time
Thanks for that, I am looking forward to seeing you cast copper again.
Great video
As always, excellent work! Those castings look perfect. Curious to know how they will machine :-)
So do I.
@@luckygen1001 :-)
epic love this - thanks
It's always a pleasure to learn from you! Thanks
Again I learn a little bit more. As soon as you mentioned angle I knew what you were up to. Glad that it worked out well.
So am I, cannot wait to machine it.
Nice job. That pour seemed to go on forever. Do you ever leave the casting to cool down overnight? Does it make a difference?
Regards,
Mark

Excellent content- as usual !! Thanks for sharing, luckygen1001. Is the crucible cam behind a new protective screen?
Glad you asked! The protective screen is a square shaped piece of glass to shade the camera from the intense heat from the crucible.

Congratulations!! Melting is so addictive. Best regards from Spain
Yes it is!
Nice castings, well done!
Thanks for sharing!
That is a very elegant solution to the problem.
That is a old patternmakers trick to fix that problem.
Interesting work.
I was wondering if you have ever considered demonstrating lost foam casting? I really enjoy your work!
If it did not smell so bad I would try it again.
Drip some acetone along the edge and shove a feeler gauge into the super glue ?
Doesn't the acetone soften plastic?
ya it might. acrylic, polycarb may be ok, but styrene type would melt. hehe forget what I said.
If you rammed your surface plate pattern on the cope instead of the drag would it help with minimising the shrinkage on the center?
I tried that two years ago and got the same result.

Hello . minute 6:50. What material was the ladle made of? where can you buy the ladle?
I was hoping no one would ask that question. I went to a foundry closing down sale and purchased 10 of those ladles from a bidder who purchased a large amount of boxes of those ladles. So I have no idea who makes them, perhaps some one reading this could tell you where to buy them.
@@luckygen1001 wow what luck I have
