Yes I did make the patterns and casting.
First is the stand mold,second photo is the cylinder head and steam chest, third photo is the stand pattern and the cast stand.
I used sodium silicate and plain sand for the cores. I also make them hollow, 2" O.D. with a 1" I'D. hole, instead of using Co2 I let them air cure there's enough Co2 in the air it just takes longer for them to set up.
I'm too impatient for that, I stick mine in a ziplock bag and fill it with co2 from a bit of baking powder and vinegar.
I had not thought of making them hollow, that would speed up the hardening.
Thanks
