I agree with dubbletrubble, if you're going to work on guns get a good set of gunsmith quality screw drivers.
I've owned several NS's and here's what I do.
Take off the butt plate, underneath is long bolt that holds the stock to the action, remove the bolt and take off the stock.
Do not take the action apart!
Soak the action overnight in a good solvent, I often use Coleman fuel.
After soaking take an aerosol can of automotive brake cleaner with the long plastic nozzle and hose off sensitive inside areas like the sears.
Dry by letting it sit open-end down on your workbench overnight (or use an air hose to quick dry it).
Get an aerosol can of gun oil with a long plastic nozzle and use it to lubricate the bearing surfaces inside the action.
Let the action sit overnight open-end facing down on your workbench to allow excess oil to drain out.
Wipe out any more excess oil with a rag, put the stock back on and you should be good to go.
This way you don't have to hassle with taking the entire action apart (and maybe causing a trip to a gunsmith to put it back together).
Good luck,
Steve
