Mike -
The fastener specialist at the hardware emporium that I patronize is
vehement on this subject. Never combine a (split) lock washer with an ESNA
(elastic stop nut assembly, sometimes referred to as a 'nylock'). The
split lock washer pushes the ESNA up and eventually defeats the locking
capability. This leaves the nut attached, but loosely. I've never tried
to use ESNA's with star lock washers. When fasteners are left undisturbed
for thirty years, they tend to fuse into semi-corroded lumps having their
own locking properties.
