Re-drilled SS supports in order to fit M3 screws.

Used hand tool cleaned with alchool for 6 of the 8.
Had to use machine for another two with thread damaged.

All 8 will be sent for cleaning. Should be able to start mounting at least the 6 ones tomorrow.

Reason for lack of fit still not clear. They were tested in Edinburgh. Possibly result of high-temperature baking?
