Um... I didn't say they were. They can be made INTO servos quite easily,
and if you have an application that won't mind the inherent backlash in the
geartrain, they're quite powerful and quite inexpensive for the torque
they'll put out.

My own thinking is, if you are smart enought to make a servo out of a
wiper motor and adapt it to a milling machine, you should be able to
make enough money in less time to simply buy proper equipment.

Changing a wiper motor into a servo motor only requires a feedback
device. An encoder will do. The wiper motor will probably not make a
very good servo motor though because there are not many segments in
the commutator compared to a motor designed for servo use.
