    I am simply making a contribution to the thread, and since I don't have a picture handy, was just explaining the tools used......a punch of whatever size the job dictates to be used, and a pile of oil soaked bits of toweling or rag. I was going nowhere else with it, and am puzzled at your response.

    What is it used for is my question posed to stump you or other participants. I guess maybe I have stumped, or confused you, at least.

    I'll bite......

    Pour the oil in the bowl, Mix the paper/oil with the punch until fully soaked. Then take the hammer and whack the center of the bowl.

    Used to put oil spots all over the front of your shirt ? [​IMG]

    Looks like you are making packings for a blackpowder bb gun...???

    Maybe prelubing threaded holes for easier assembly...???

    I checked the anarchists cookbook and all the past episodes of Doomsday Preppers and got nothing.

    LOL. It's used to hydraulically remove bushings or bearings from small blind holes. Such as in a starter or plow motor end cap, cam bearing, bushed shafts in gear mechanisms, needle bearings from ends of gear shafts, etc. Removing the bushing from a flywheel would be a larger example it could be used on if you were shy the proper blind hole puller.

    Punch needs to fit closely the bore of the part being removed. Pack the hole with oil soaked wadding and tap the punch in. Pressure from behind drives the bushing or needle bearing cage out. Add more wadding as the part pushes out.

    Ok, I've used the same technique for getting pilot bushing out of cranks. Just not a tapered drift punch.

    Huh?? The punch in the pic ain't no tapered drift punch!

    I've tried that trick, never had too much luck with it. Tried using grease, etc., finally broke down and bought a blind bushing puller.

    I usually thread a tap into the bushing...when the tap hits the bottom of the hole it threads the bushing out..
