The SR&CL Ry foundry, watch our progress
HI,
We are starting a foundry and needed a burner to warm things up. Found a plan at Lionels Metalcating page and built it. Made it an in-line versis his 90 degree one. Nice blue flame.
Next up is a cart for the furnace and a handle to lift the lid.

tomc, DANGER < DANGER WILL ROBINSON! ok, oil your molds, after you blast them free of rust. DO NOT pour molten aluminum into the molds I see. They will POP and Explode molten aluminum as you pig out. I have the same forms but they must be FREE FROM IRON RUST, or they will pop and spray aluminum when poured. This is the same system I use, but HEAT the molds to prevent water from condensing on the molds and remove oxides as the AL will react and pop the molds splattering the shop. Ask me how I know. ( GRIN)..
Ya, you got it goin, just do it right to be safe.
Good work, I bid you peace.

We have enough youth, how about a fountain of Smart. My computer beat me at chess, but not kickboxing
It is not getting caught in the rain, its learning to dance in it. People saying good morning, should have to prove it.

Refractory
What did you use for refractory?
Melting aluminum is fun! Sounds like a good topic. Anyhow, we are busy making ingots from our scrap. Tried a pour to a mold but I don't like the outcome. I am looking for a finer grade as I got sand blasting and is to rough.
Melted some Morton's lite salt for a flux to try. That is in the big saucer.

Hi,
Now that we have our melting down, We need a beter way to mix our sand. We are starting a mueller. It is sitting on the frame I welded up with the 83 to one gear box we found on Ebay. Below is the tub with the wheel blanks in it, the motor and center support. More to follow as it comes along

For fluxing aluminum, use HTH pool tablets broken with a hammer into sugar cube size lumps, wrap powder and small pieces in foil, use an infuser cup to add to the melt, skim dross, pour.
Make an infuser cup by making a cup shaped disc with a few 1/4 inch (5/16) holes drilled in a pattern, and weld it to a rod of about 3/8 to 7/16, maybe some 30 inches long. A packet is made with the additions of aluminum foil wrapped onto the edges, and the works plunged into the melt and spin/swished to flux the melt right before pouring. Be decisive with your moves and only take a second or two to move the melt and stand back, away from the fumes.
Warning: the chlorine gas is small but not good for your health so stay upwind and in a vented area. ( a box fan serves for me keeping the breeze going as I bake in the love of a melt.)
