My only problem now is that the crushed chippings contain some very small
sharp flakes which may harm the lining. I don't seem to be able to sieve
these out since I cannot get the chippings dry enough - even a small amount
of moisture makes the very small flakes stick to the larger pieces. Washing
is not reliable for much the same reason.

You could rent a cement mixer and tumble them for a few days.

I don't know what liner you are using, but I have a 20 mil Permalon
and a 40 mil rubber and wouldn't hesitate to use them in either pond,
if that was my desire. I did in face keep river pebbles in the 40
mil rubber a couple years, but cleaning was such a problem I stopped
doing that.
