Thanks for the great suggestions, esp about purring the supports before adding roof weight and experimenting on a wall to be torn down. My papercrete does cut easily. I'm not sure how the pumice affects it, except maybe to dull the blade.

Subject: [papercreters] Cutting Window Openings -was- Re: Post a question.
I can't say I've built a papercrete wall and cut out an opening like
you describe.
In my opinion, the process should work reasonably well, as long as
the particular papercrete recipe in question is reasonably easy to
cut. Do I remember correctly that you talked about your blocks being
easy to cut? I don't recall how the pumice impacted cutting.
I highly recommend using some kind of support. Lintels or window
bucks seem to make sense.
I also recommend that you cut the openings and place the support
structure in place before any significant loads are put on top of the
wall. If you wait to cut the opening until after roof loads are
applied, you may get some sagging before you can put the supports in
place. If you are going to put some kind of box beam on top of the
wall, I recommend putting that beam in place before cutting the
window/door openings.
Do you have an existing papercrete wall that you plan to tear down?
Can you try an experimental window cut in that wall right now?
Perhaps that will give you better answers?
Another testing strategy. Perhaps you can try your favorite window
cutting technique on one wall as you build to find out how well it
works before committing to doing it that way for every opening on
every other wall?
For what it's worth, that's my opinion. (Put my opinion in a sack,
and it's worth the value of the empty sack.) (I'll let Spaceman
explain the origin of the original quote I modified. hehehe)

Does anyone have experience building an entire wall (slip form or
block) and then cutting out the doors and windows? I am wondering
what is done about lintels.
