[Cob] roto-cob

[Pavel Velikodvorsky]

Thanks, Robert!
At the first days of the trap mixing I got that yes, it's a very 'romantic'
way to mix a cob :) if you know what i mean, but it will take ages to
complete some serious project, unless you have an army of helpers with
tarps - which i don't.
The first thing which comes up to my mind about this rototiller - either it
will crush the straw in a smaller parts (which is undesirable) or not, and
will the straw stuck in its blades or not? I remember I had the same fears
about the concrete mixer - but it turned out just fine, i just made my mix
a little wetter.
So I'm really start to think about this roto-thing, it looks like it will
cost less to buy one than hire some kind of 'bobcat' for mixing. Maybe i
will be lucky enough to rent it first to try before buy :)

Regards,
Pavel
