Some topics about Burnishing :
wheel bore prep:
Stan Pope also has a web page with a few techniques as well.
Here lately after getting fed up with destroying wheels.. with using pipe cleaner's with wires or the Q tip shafts that swell up.
I've moved on to using the Tamiya spears for all of my wheel bore prep now as I'm having better luck with using them.

The spears can also be found at Hobby Lobby in 3 different sizes.
Apparently .092 kit nails were used when the book was written. Very briefly, and probably not super detailed, here's how you do it. Buy some .092 axles, or use a drill bit, put some graphite in the bore, stick the nail in the bore, roll the wheel up and down a flat surface several times about one foot each way while applying approximately 1 kg (2.2 lbs) force to the axle.
FWIW, I don't do it.
From there I work it into the wheel bore for about 15 sec. on a slow to midium speed on the drill.
Then i'll re-dip the spear and reverse the direction of the drill and work more graphite in for the same amount of time.
I'll even change sides of the wheel.. outer hub side forward and backwards in the bore..inner hub side forward and backwards in the bore.
I even use the spear to work graphite in to the inner hub ring & outer hub.
This way just seems to work better for me as a personal preference.
Most will use something like a polished rod, or smooth end of a drill bit, and even the Derby worx pro hub tool to burnish the wheel bores and inner hub with graphite.
By rolling the wheel back and forth on a flat surface.. to embed graphite into a wax or
Into the pores of the plastic wheel bore.
Some problems you can run in to by doing it this way.. could be caused by pushing down to hard with one of your hands as you roll the wheel.
This can cause an angle in the wheel bore if your not careful about it. ( so the wheel wobbles in spin testing to the axle!)
At least that was some problems I ran into no matter how careful I thought i was.
