take a look at this!!! https://www.youtube.com/watch?v=nNEcoBdIsnc&t=605s
This video is really fabulous. I have always wanted to know how they made iron pots and this shows at least one very slick method. It doesn't have any feet on it as you see with American Pots but otherwise it's the same. [I suspect the feet on American pots are placed there by poking a depression in the mold after it is rammed up and the pattern is removed.] The one thing that they did not show in the video at all as how they cast the handle on the lid if you look at the video starting at about 9 minutes and 16 seconds they start making the lid to the pot. Why in the world he didn't make both molds and cast them at the same time I don't really understand but he certainly has got better skills than I do so why should I question him. At nine minutes and 49 seconds you can see the lid handle in the mold briefly. He has obviously dug down to the top of the pattern so he could put the lid handle pattern on. He then put in the sprue but you never see him take the handle pattern out. At 10 minutes 16 seconds he takes the mold off the pattern and cleans the sprue hole. At 10 minutes 36 seconds he dusts the pattern and you can see that whatever pattern was put in there for the handle is gone and there's just a hole. Does anybody know how the heck he did it?
My other question is what is all the white powder, is it talcum powder, is it corn starch? And why does he Dust the mold so heavily. I can understand it before the mold is parted but he is dusting it after the mold is parted from the pattern.
I really liked the use of a feather to clean out sprue holes. We can learn a lot from his "best Practices"
All in all I'm totally impressed with this video. It is really interesting to see them use just to cope and not a drag in making patterns. They're using The Foundry floor as the drag. I've seen this in Indian commercial Foundry videos as well. It sure saves a lot of time on casting an item that is flat on one side. Or if you have skills like this guy you can do it with an item that's not flat on both sides. Just cope down to it.
