Edit Reason: small addition

Bigend nuts should not need washers. Originally they were split pinned and the nuts are sized for the castellations to be correctly positioned for the split pin. I have found stretched bolts where washers have been added to create the correct location for the split pin, but this has been the result of the bigend bolt being stretched by overtightening. Such bigend bolts should be scrapped. Many of us (most?) now use self locking nuts which avoid the problem of the split pin not lining up with the castellations. The bolts locate in the top half of the bigend so neither the bolt nor the nut can turn, obviating the need for any washer.
