i have been experimenting with making a cob mixer for awhile, the best i have come up with is thin wheels loaded with concrete block to mash the cob, it works pretty well, wondering what others have come up with to make it where it is not so wet and makes it quick?

I haven't gotten to making cob (yet) but Ianto Evans and others who have done a lot of it say that a cement mixer won't work. A mortar mixer, however, will work, according to them.

A rototiller, however, I'm pretty sure WON'T work -- because the cob is mixed with long straw for strength and that would wrap around the tines of the tiller, making a real mess that would be difficult to remove.

Kathleen, who has no better solutions to offer at this point in time!

you all have two great cob mixers already at the bottom of your legs.

Soil, I'm not sure each and every one of us is standing on a tarp.

it works like a cultivator except it is wheels instead of sharp pans, just wondering what anyone else has come up with, looking for the best for less without electricity or gas

I've read the most effective way is to take off one's shoes, pour a batch out onto a tarp, stomp it around, and fold it over using the tarp.

Still a lot of work, so I hear, but not nearly as much as other methods.

hmm here is a more or less comprehensive list of mechanical mixers that sorta work.

Tractor
tiller
car
plaster mixer
cement mixer with rocks in
lawn roller

I am missing one or five but thats the jist

then we have the foot brigade and this all seems to work much better.

donkey
cow
jackass (who knew there was use for a son in law)
Horse
goat (s)
Clean humans
dirty humans
daughters (however; i have been told that these occasionally bring about the jackass's)
unihumans

and welshmen.

thats pretty much every mixer i have seen so far.

Need more info?

Best I have found is my Bobcat, but it is in the tractor category.

I just posted about this and was referred here. Thank you to whoever came up with the idea of using a rototiller!!!

Rototiller cob is super easy and efficient! I will add a pro tip, use an electric chainsaw to chop your straw while it's still bailed. Get a pitchfork and a wheelbarrow and some good gloves.

I am testing immediately plastering the cob while it is still wet it, this should be perfect for the lime plaster since it will allow a slow cure.
