Well over a year ago, someone here posted that they had tapped the hole in a neodymium magnet for a fitting that would take a piece of, if I remember correctly, 1/4" plastic tubing.
The magnet was strong enough to stay fixed in place over the touch hole while pumping vigorously up and down the barrel with a tightly fitting cleaning patch.
Several others said that they liked the idea enough that they were going to duplicate it.
My question is how well did the system work out over the long haul with over a years use under your belts?
Also, where did you purchase the magnets? And, what type of tap/ fitting did you use?
Thanks,
