It sounds like Don has solved Brian's problem.  

The Motion Pro tool looks great Justin but it is $40...  

As mentioned earlier, if you want to make the tool, bolt and nut
*quality* matters.  Look for a supplier* (under "Bolts & Nuts" in the
yellow pages) and ask for "SAE grade 8 (or metric grade 10.9) or
better".  Here's a comparison chart: http://tinyurl.com/58xkd.  

The ideal bolt will have a 3/4" / 19mm head and just enough threads
for two nuts. 1/2" diameter x 3/4" length and 12mm or 14mm diameter x
20mm length should be perfect.  Look here http://tinyurl.com/qhp7r for
head size variations due to different standards.  An auto repair shop
which specializes in Asian car repair may have a JIS standard 14x20
bolt lying around.

Tighten the bolt head & nuts together with the flats aligned and no
gaps.  Then weld everything together.  You'll have an inexpensive tool
which should outlast your bike.


Some axles may have been over tightened.  Torque is 60nm/43ft/lbs.
It's good to apply a film of grease to protect the axle from
corrosion.  Don't forget to torque the axle pinch bolts and the
caliper mounting bolts - 20nm/15ft/lbs and 40nm/29.5 ft/lbs
respectively.

* Portland isn't a huge town.  We have at least 15 such suppliers in
the area.
