Removing hub spacers so axle protrudes from drop outs more?

I have a road bike frame spaced 130mm and a shimano hub spaced 130mm also. I am using an old style nutted axle and am finding that the axle just barely protrudes enough beyond the rear dropout for the nuts to grab enough threads. It's so close I wouldn't be surprised if it stripped when I tighten the nuts

Question: Instead of getting a longer axle, could I just remove the hub spacer on the non-drive side and crank the nuts down tight? I'm trying to picture how to do this in my head without throwing the rear out of alignment or doing anything stupid.

Thanks folks!

you could do this and it would buy you more axle.
it would also mean that the spacing of the hub is narrower (say you removed two 2mm spacers, you'd drop the hub spacing from 130mm to 126mm). this would clamp the frame's dropouts slightly narrower, which is absolutely no problem with steel or titanium, probably only a theoretical problem with aluminum, and likely a no-no with carbon fiber.

as long as you remove the same spacing from each side, the wheel will likely stay centered between the rear brake. But you may not have space on the drive-side (depending on whether the cassette of gears is already close as possible to the frame when the wheel is installed on the bike). And if you remove dropouts from only the non-drive side, you'd need to re-dish the rim. which means a weaker wheel.

it's probably best to just get a longer axle.

If you remove an axle spacer you will change the OLD, meaning doing the nuts up will squeeze the dropouts together potentially upsetting the alignment of the derailer. Will in extreme cases introduce a bending force on the axle. Might also affect the alignment of the wheel in the frame.

Might also work just fine, w/o any side effects at all.

I think that the cost of a new axle is well worth it for the piece of mind it will offer.

As noted removing a drive side spacer would change your derailleur adjustment (and chainline). The other potential problem is that even if the spacer is not a tabbed lockwasher if that is the only thing between the cone and locknut you need to be very careful to lock the two against each other very solidly.
