Green sand moulds for cast iron muffler

I made this video for anyone that is curious about how a sand mould is made for pouring molten metal into. In the first mould I use a reinforcing rod to stop the fragile greensand core from breaking. In the second mould I forgot to drill a hole for the draw spike and show a different way to extract the pattern from the sand mould. The third mould shows the normal way to extract a pattern from a sand mould. The castings were for a muffler for a 3hp Fairbanks morse engine that belongs to a friend.

Tell us a bit about your sand muller - is it a home brew?

It is a rough copy of a mixer I saw in a museum in Germany a long tme ago, so simple to make and works so well. When I first ran a cupola I thought there must be a better way of mixing large amounts of sand and this mixer is exactly what I needed.

Any chance you can put some pictures up showing a few details? - I need to go down this road myself soon

Click onto this link and you can see all the parts of my sand mixer, a video is always better than photos.

Excellent! I've not re-established my foundry since I moved here a while back (*), but I'm getting close! I was floor mixing but that seems a far superior way forward
* the non inflamable building went up a year ago but was annexed for temporary storage almost imediately
