  FeaturedContest Winner Picture of Bicycle Wheel Truing - on
the bike, with a marker pen. 002 Line WheelInst UL.JPG 004 Low
SpotsInst UL.JPG This is a really easy technique of truing
bicycle wheels, in the frame, using only a white board marker
pen, a Chinagraph (black wax glass cutters / art pencil) or a
black wax crayon, or a permanent marker etc.  The best marker
needs to be DARK and reasonably opaque - and easy to remove.
Black white board markers are best, black wax crayons,
chinagraph pencils and indelible markers running a close second.
(see my next Instructable on resurecting white boarrd markers)
It works like this:  The rim is rubbed with a dish washing
abrasive pad and some kind of solvent such as kerosine,
turpentine, acetone, dish washing soapy water etc... making it
more or less oil free and clean.  An ink ring is applied to the
side of the rim, by placing the marker on the side of the rim,
and rotating the wheel slowly.  Then the wheel is roatated
really fast, some kind of friction material
