Hi I have not posted for a while (work sucks) At present we are building the Hasbruck no 8 v twin steam engine. A brass fly wheel wopuld look good having no 5 inch bar to hand we decided to have a go at casting some. Some fire bricks charcoal and a leaf blower were quickley assembled. A crucible was fashioned from a length of 5 inch stainless pipe and the fire lit. After 3 bags of charcoal and 1 hour we had molten brass some brazing flux was added to the mix and a simple mold made from sand. The metal was poured sadly not enough but it worked. As the brass cooled we cooked lundh on the hot bricks LOL I took a light cut in the lathe and was very happy with the results. Next tine i will try coke as a fuel |

After my earlier attemp to cast brass cwe decided to build a propper furnace. A nice stainless beer keg was accuired the top chopped off and a base constructed. A start was made on a propane burner (bunsen burner but bigger) I now need some castable refractory cement any suppliers in north ease \england |
