David,
Two other methods that some will suggest are air pressure and hooking up
a grease gun to force it out. From my experience though on TDs with the
dissimilar metals you will not have any luck. What I did to stop
replacing mine every two years was buy new ones and send the cylinders
to White Post to be sleeved with brass and there has been no more
problems for 10 years.
Good luck.
