You'll need to order the wax and have some sort of buffer to apply it. I just a 6" buff mounted in a hand drill clamped in a bench vise. I'd recommend getting some red tripoli buffing compound and white diamond compound as well (separate buffs for each).
If the stems are oxidized (turning some sort of brown, green, or grey) they'll need to be sanded. You can bleach soak them (put some petroleum jelly on the tenon) and soak in some bleach-water solution until they turn a rough black. Then you have to sand them smooth anyway. 400, 600, 800 or so should be good, maybe just 400 grit. Then the whole pipe can get red trip, white diamond compound, and if you want wax the whole thing (the stem may not need it). Make sure to do all the sanding and buffing with the stem in the pipe, or it'll round the edges and you'll make the transition from stem to shank sloppy looking. I'm not sure exactly how to do this without sanding the shank and having to re-stain it, so maybe someone better can chime in.
For the chamber, after you ream it out, you can do a salt and alcohol treatment (Google it) or use a retort (available on eBay, see video at end). Just be VERY CAREFUL not to get alcohol on the finish, because it can mess up the stain.
I hope this is helpful!
