[Cob] arched door, frame?

[Christopher Reinhart]

"The question is: on the knob side of the door, do you think I should put a
wood piece as that door stop, or just have cob and plaster for that, with
perhaps a deadman in place for the lock/clasp to go into?"

I would most definatley install a wooden stop for the door.  The stop is
bound to take a beating, and if you go with just the cob and plaster it will
crack/crumble over time.
