[SADXA] Grease gun?

[WD7F - John]

I have one.  Just bought it and the 5 tubes of grease that you have to buy
'cause they don't sell just one. Guess what I need it for?  The two bearings
on my rotatable tower.  I even bought new zerks...and oh yeah, I had to buy
10 of those.

I'm having troubles rotating the antenna on my old tower and have isolated
the problem to the tower's thrust bearing.  It's taking too much effort to
rotate, and my rotor software is going into a "safety stop" mode.

In looking at the setup I realize that it's been about 25 years since that
thrust bearing was lubricated.  It feels like the grease around the ball
bearings has dried up over the years and that's causing a lot of extra
friction.

Lubricating the thrust bearing should be easy to do.  The bearing takes a
standard automotive Zerk fitting, and it's sitting at about knee height on
the bottom of the tower.  It should be an easy job except that I gave away
my grease gun years ago, when my wife and I were lightening the load to
prepare for the cross-country move back to Tucson.

Does anybody have a grease gun that I can borrow to fix my problem?

Thanks,   Jim  W9FI
