The smallest diameter CV joints I know of are found in Quads. Might be a
bit pricey, though. Car joints tend to be a lot cheaper for remans as they
are
mass produced. Note that all CV joints are not created equal, as far as
allowable
angularity is concerned. This would affect machine use as far as smooth
power
transfer is concerned. Maximum operating angle depends on RPM and if RPM
is low, say under 1000RPM you could operate a simple Cardan joint at 10
degrees
or maybe a bit more. If that is enough, just go to a parts jobber and get
PTO
driveline stuff which is small and easy to work with. Be sure and ask for a
U-
joint parts catalog...lots of good info.

Note that double-cardan joints are "CV Joints" but their max operating angle
is
less than a Tripod or Rzeppa.
