After investigating various ways of building a base for a garden
shed on
sloping ground I've bult a wooden frame out of treated 2x3 and plan to
drop 6 uprights into holes that will be filled with postcrete.
Initially
I was going to make the uprights by cutting stub concrete posts in half
but am too concerned about the steel rebar (spalling and drilling
holes)
so then decided to use treated 4x4 and accept that they will rot over
some years. Now I'm wondering about cutting strips from thick
(non-reinforced) concrete slabs and using those on end - they should be
OK to drill and there won't be significant sideloads.

Any comments?

You could cut the concrete post & epoxy the top of it. Wood I woodent,
its bound to fail on you.

What the OP needs is some cardboard tubes out of carpets and some ready
mix. He can dig holes, put hardcore in the bottom poor some concrete in
and when set put the tubes in and cut to the right height and then fill
with ready mix.
An interesting idea (ignoring the difficulty of converting carpet to
cardboard ;-) ) - that would give me pillars to set the base on but I'd
prefer to have something I could put a coach bolt through.
The Yanks use something simlar to cast deck footings, casting brackets
into the top. I don't see (though someone else might) why sections of
110mm plastic drainage wouldn't make useful forms for pouring concrete
in this sort of application. Not expensive, and much simpler to source
than going around begging carpet shops for their cast-off cores.
