Working on a new tiny shop
PekkaNF:
I have done very little casting but always wanted to. More I read, more I'm convinced that i need to start from low tempreture stuff. But I read and try to learn.
But you guys! Sometimes I don't know if you are talkking real utensils, parts, methods, tools or just joking and mixing parts of s-type minoritties. Unicorns and cowcorns :lol:
But keep it on rolling, I finally get it when a leg getts pulled.

Well Pekka, the truthful part is I want to get the metal coming in at the bottom of the mold cavity, but using simple molding methods with this shape pattern, that area is inacessible. So one possible method of getting a passage for the metal to that point is to bury a horn shaped plug with the point down, at the spot where the metal needs to go, and then pull it out after the sand is rammed in place. Because it is both curved and tapered, it should come loose without disturbing the sand, and give a passage that you can pour into from above, and which chokes down to a small opening at the side and bottom of the mold cavity.
Does that make more sense?
Manxmodder:
Steve,it is a real possibility that real horns may have been used at some time,just considering the fact that horn is easily whittled and sanded smooth and it is also easily shaped by heating and bending.
It therefore may not be such a silly idea after all.....OZ.
vtsteam:
Yup, that's what I was thinking :thumbup:
vtsteam:
But, I've already made the cheek flask the same height as the pattern, so a horn sprue will have to wait for another project! :beer:
