I've read a few of the books on building RMH and I have the DVDs
My main idea for the use of castiron in the build because of a few things:

The use of a long turn 90 would make it draft easier.
A 6" round has less friction loss than a 6" square does.
Cast iron is what wood stoves are made of.

I'm a plumbing and and HVAC tech. I live in a small town area so I get to wear lots of hats.

Also should have done more searching on my laptop as opposed to my phone. There are a few threads on this subject out there I failed to find. Thanks all.

Hey I know this will sound heretical especially to Paul Wheaton who has a YouTube video saying not to use metal in the burn tube.

But I am a plumber and have access to cast-iron sewer lines and long turn elbows. So I’ve been wondering for my first build whether or not a cast iron burn tube with cast-iron riser would be acceptable.

I have looked all over and have never found anyone who actually made the burn tunnel out of cast-iron versus regular steel. Thanks to any contributors.

We had a similar problem with our dairy back home. I know this might be a bit of a pain, but you could try setting up a gate so they leave their shelter/ go to feeders by a slightly different route each time. North the first day, west the second. That way you don't compact the soil. (this is part of why the ground won't take the water away)

I'm a printer so.... There are petrolium products in the inks, the kind of alchol that caused blindness in the fountain solution, glue no one should eat in the paper, the paper fiber themselves go through bleaching, book covers usually have UV lacquer or varnish on them. So I'd STRONGLY suggest that you not do this.
