When replacing the cones for a front hub with new ones, is it okay to tighten the lock nut directly against the cone nut? Or must I use some kind of spacer / washer / shim in order for some other reason than spacing?

The reason I ask is that I am replacing the cones on a front hub that was correctly spaced at 100mm. The old setup has

Lock nut - Washer - Cone nut - Hub/Cups - Cone nut - Washer - Lock nut

The replacement cones I got match in the old ones in all ways except that they are slightly wider (i.e. take more space of the axle). So, instead of getting two more cones ($20 more dollars!), I figured I could just leave out the old washers and leave the setup like this, which would be spaced about 100mm:

Lock nut -      New Cone nut - Hub/Cups - New Cone nut      - Lock nut

So, would this be alright? Does the original washer play any other role than just making the spacing correct?

Having washers between the two nuts is probably more the exception than the rule. –  Daniel R Hicks Jul 11 '13 at 3:29

I've just rebuilt a totally stock Shimano wheel set and it had locknuts touching cones all over the place. Go for it.

Can I assume you mean that the stock wheel had no washers before the rebuild? –  PositiveK Jul 11 '13 at 23:51

That is exactly what I meant. –  alex Jul 12 '13 at 2:31
