I keep looking for a spark plug spanner for the CM-6 plugs that I find all over the place but all I ever seem to find is box spanners or '10mm' ones with 16mm hexes
I have finally given in and brought a couple of long reach 14mm sockets from far eastern lands on Fleabay - cross drilled for a tommy bar I think these will do
They rather show up my other sparkplug spanners made from sawn off 2BA box spanners that I use with the 1/4" sparkplugs.... So I have just, for the vast sum of £1.92 the pair ordered some 8mm long reach sockets to make the set
