Frosty, Not sure what to do here. Not sure they are willing to rebuild this and if they did it would be in the off season when the park is closed. If they were I would suggest a side draft. Probably just going to have to deal with. I can get a good for heat better than propane for sure. I am mostly doing demonstrations for the public, but they are starting to ask me to do more projects for the park. Might just have to bring them home and MIG weld them. Would be much easier to just forge weld it right there.
