you can add your own jerk fittings
http://www.saeproducts.com/thread-forming-grease-fittings.htmlmagnetize the correct drill bit
by attaching for 24 hours
two super strong button magnets
like the small rare earth ones
that can be bought in a six piece pack at Harbor freight.
http://www.harborfreight.com/10-piece-rare-earth-magnets-67488.htmlif you use a slow rpm speed drill
you can even leave the button magnets attached near the tip
If you wish coat the bit with heavy grease to further catch metal or paint shavings.
drill just a little at a time,
then clean and recoat drill
you may also want to magnetize the jerk fitting
to hold onto metal shavings
in my opinion
the threat from metal shavings
is far less than the threat
of water getting in the joints
when it is not packed with grease
DO NOT OVER GREASE
as you can do more damage
blowing out the seal
which will allow water and contaminants in
go slow with the pumps of grease
stop at just a hint of grease coming past the seal
