What PunkRockBoy said. The bolt is easy to disassemble, but do it in your bathroom, with the toilet lid down and the plugs in the sink and tub the first couple of times, because it's possible that a spring-or-2 could jump away from you.
I use the rifle and '06 case to put the bolt back together, really makes it simple.
The first step is to grind-off the rim for about 1/2 of the way around on a .30-'06, .270, 35 Whellen etc.
Reassemble the barreled action using the striped bolt (with the roller on it, of course) like you would the normal bolt. Then, with it muzzle-down, slip the firing pin in. Now take the gun to a nearly level position (still slightly muzzle down), pull the cocking handle to the rear, drop an '06-size case into the chamber with the ground-off rim in the 10 o'clock position. Put the ejector spring and ejector plunger into the hole and slowly slide the action closed on the case. You'll have to push the cocking handle forward to completely compress the ejector spring. Then align the extractor and snap it in. The ground-off rim just makes it go a little easier, it's not essential.
