watermelon Posted January 6, 2018 Share Posted January 6, 2018 i think i have found a section of drain pipe, that is cast iron to use for a tuyere. is cast iron a good material for a tuyere? how can i test it? it has been outside for some time, it has some paint and rust on it. if i clean it up should i protect the surface or let it gently rust?

Tubalcain2 Posted January 6, 2018 Share Posted January 6, 2018 Cast Iron makes great tuyeres. wire brush the paint off, and use BLO to keep it from rusting, or just leave it like it is. Most folks leave it. Quote Link to comment Share on other sites More sharing options...
