Metal Casting at Home Part 10 Another Day in my Home Foundry
How to make a casting from making the sand mould to the finished item. The video has been edited to fit the 10 minute time limit of You tube. It takes much longer than this!

This has got to be the best one of all your videos i’ve seen so far – A man after my own heart!! A1.
Marvelous…rather like being Vulcan at his forge, ya know?
The little amount that it will absorb wouldn’t make any difference to the mold. I have used graphite, ground up brick and silicon spray. I try not to use silicon spray too much just in case it coats too much sand/clay and stops it from sticking causing the mold to fall apart. It does work though..
fantastic job i learned something with your video
Core can me dug out from holes in the casting ends. Breaks out easily.
Simply awesome process… How do you remove the rest of the core?

Should be added to ‘more info section’.
Great video.
Great casting videos!
Thanks a lot for you efforts and for sharing!
Works well for me. Doesn’t seem to effect the sand, its only a very thin coating.
Ah, so talc works well as a dusting powder? Correct me if I’m wrong, but doesn’t talc absorb moisture out of the sand?
There are 3 location points added to the pattern known as core prints. These leave a void in the sand to support the core in the correct location. You can see this at 4:40.
How do you get the sand cores centered? It seems like they would sit on the bottom of the mold, leading to one side being very thin and the other side thick.
I was given mine but I would try John Winter & co ltd who adveritise in Model Engineer as suppliers. You can get a free catalogue. Google will find them.
i there were do you get your casting sand from?
I live in the country! I wouldn’t worry though its no more halmfull than a barbeque.
Have you run into and Laws/Bylaws/Annoying Neighbors that frown on doing this kind of stuff in town?
If you compare the pattern with the finished casting you will see the two parts of the pattern when fitted together have 3 extra round sections on the ends. These are the CORE PRINTS and form impresions in the sand to locate the core in the correct place.
How do keep the core centered in the mold?
Ok I’ll see what I can do.
that is prity cool i do it in school and it turns out good but yours is nice
If you’re looking for more video ideas, I’d love to see more of the machining process. Great videos, please keep them coming!
Its the engine block for a half size Stickney engine model.

Great series I watched 1-10, I was very impressed!!
