[permaculture] cob mixing?

I'm not clear why one would have big rocks in the clay??  I have always
screened my clay before mixing.  I t can be done with hardware cloth up to
1/2 inch and it should pass the mortar mixer test with no surprising jerks.

Ive had some friends that used a mortar mixer, they said that it works but
if theres larger rocks in your clay the mixer might catch and give you a
mighty jerk so be ready. Make sure you get insurance on your mixer they
experienced some hefty dents from stubborn rocks. If its a time and manpower
thing go for the mixer but if you can dance your walls into creation dance
