All these tractor guys & wanting to do things the hard way! Looks like I've been away too long. What you need here is a little thought into how to pull up that short piece of rusting pipe, that is the way people get there vitimans & iron, is it not?
In order to get the pipe out first, you really need something kind of tall, like the front loader of a tractor, or a loading pole on back of the three-point hitch. That's better than trying to build a tall structure to place over the punched well. A simple pulley hoist (an electric works great) mounted above and using a rope wrapped several times around the pipe as a friction grip will hold onto the pipe as it is being pulled upward. Once you get it moved upward as high as possible, repeat the process (to hold it until you get the winch reset, place a sawbuck over the well, use another rope to tie another friction grip, rope is cheap) until getting to each joint that requires seperating. After getting all the sections out, fix whatever problem you had, and then get some FLEX plastic tubing (there's two different grades of that stuff, get the heavier-duty black plastic version). I would also certainly cover the wiring with some sort of protective flexible covering, especially with deep wells. Had more than one occasion where the wire got cut rubbing against the stone walls of the well. Vibration reducers just don't cut it. Then it's fairly easy to drop the plastic down, even for one person, wire-tying the covered wiring about every 15 ft. to the plastic pipe. Wire needs to have slack!
But, mine's plastic PVC at 500 ft., how can I pull that out, & the water makes it even heavier?!?! That's the #1 reason we all bought tractors, right? Just place a barrel (55 gal plastic one works great) next to the well casing that sticking out of the ground, tie or stake the barrel into position so it won't go anywhere. Again, use a rope to wrap it several times around the plastic pipe for a friction grip, the other end goes?....Oh yeah, on the hitch of that tractor I bought just to do this job! Get the father-in-law, who's been dying to try out the new toy, to mosy up the driveway while you watch the pipe slowly coming out of the well casing, guiding it & watching for anything that may catch the pipe from moving freely. And remember, for you people with deep wells, if the old person driving the tractor can't see your hand signals from a distance when trying to get him to stop prior to ripping apart the pipe & losing the pump forever, use those family-talk CELL PHONES for something besides gossip.
