I am new to the form but have been learning quite a bit reading the post. I am not new to foundry work entirely. I have had a bit of green sand experience. I need a furnace that can cast bronze. I have accumulated the items in the condition pictured. The keg is very nicely cut. There are 3 rather unprofessional tabs for ? buck riveted to the top, 120 degrees from each other. If the liner is centered in the keg it gives an annular spacing of 3 inch and an average of 3 inch on the top and bottom. At this time a picture is worth a thousand words. I have run some test on refractory that I will post later. The fuel plan at this time is a 3/4 inch residential NG line and I will be using a petroleum based fuel secondary also. So this is where I am and I would like ANY advice and or questions on how to proceed. I do not like to look back and question if I should have looked forward and questioned.
