Hi Chris,
the method I use is to replace single bales at a time and without too much
trouble after trying the first one or two to sus out the best method and
with no moving of the wall above.
I found putting some thin plastic sheets(house for sale signs) either side
of bales to act as sliding surface similar to shoe horning the bale in, also
starting the bales off at a slight angle helped then turning them as you
push/pull into final position, use the handle from a trolley jack (or
similar sized bar/pole) through bale strings on one end of the bale for 2
people to pull from one side, whilst 2 opther people pushed from the opposte
side of the wall, then pull out plastic sheets and move onto the next bale.

I agree, it's certainly worth a try, if the render has any strength at all,
and the loads on the wall are not great.

Hi, Chris,
I wanted to suggest that it may not be necessary to install the temporary
beams and jacks that you describe, to support the wall while you are
replacing the bales (leaving aside, for the moment, the question of what
material will be chosen to replace the bales). I think you will find that
you can pull a single bale out at a time, leaving empty air, and see no
settling of the bales above during the replacement process. Then install
the new material, and move on to removing the next bale. It's worth an
experiment, anyway, in a sample spot.
This has been done on a number of repairs that I have read about in The
Last Straw, and a couple that I have been personally involved with. Removing
bales from two courses at once might change things, but leaving the exterior
lime plaster intact will transfer a lot of load from the bales above.
With the bales decaying, you may find that you can remove half a bale as
easily as a whole bale, perhaps more easily. When I have tried to remove
badly decaying straw, it comes out in handfuls, and not in bales, or even
large clumps. There is little strength left, and you can remove the straw
that you grab, but neighboring straw doesn't move much.
Pulling out half a bale width for the lower two courses of bales, and then
inserting the new material, is even less likely to require any beam and jack
support.
What do others think?

My understanding is that they are thinking of leaving the external
wall of lime intact. A few extra expansion joints before work starts.
Working segment at a time.
Breaking some holes through the width of the wall using Lance?s
coring piece.
Placing beams through these which will be supported by jacks.
Removal of straw below (still leaving that lime on the external
surface)
