Roger, sounds as if we have the same luck with grease guns. Fortunately, I learned a lot about these pesky critters while running a combine for the last several summers helping the land owner that lets me hunt on his 40 sections of land. We greased the combines every day before hitting the fields. There were 6 fittings that took 50 strokes each and several that took 20-25 strokes. I used about 1 and a half tubes every day. I kept suggesting an air powered gun since we had a compressor on the service truck so they finally got one, then graduated to 18volt rechargeable Lincolns. These are Cadillacs of grease guns as far as I am concerned. We probably use them more in one harvest than you would in your life time in your shop.
