My ball zinger experience started with a Blakoe MKIII, which I purchased for a ridiculous price but willing to pay it to try. Found it to be very uncomfortable. Wore it part time for about a week and noticed no difference, wearing it 8 hrs or less per day. Did Not Like it at all.
I then did a search for blakoe on Mamma and found Penis Workshop – Sperm and from there made my first by using a shoe string with copper and aluminum washers, I tied a knot in the middle of the lace, put an aluminum washer on one side and a copper washer on the other side and tied another knot on each side, and repeated until I had the desired length, I think I had 6 or 8 washers on each side then tied it on with a bow knot like tying a shoe. This stayed on better and was not as clumsy but in certain situations it was uncomfortable because it would pinch but I noticed almost immediate results. My problems with dribble after I urinated started to improve, less trouble stopping and not being able to control the last few droplets. Then I noticed a larger quantity of ejaculate, and less shrinkage of the testicles. I felt it was worth further improvement. Multimeter readings when dry was only around 0.38-0.4 but if I read it when I was sweating it would read from 1.2-1.5, I thought this was good.
I wore it month or so until I found the right products to make another one. This time I made it with 3/8” latex tubing, 3/8” food grade copper and aluminum tubing from McMaster Carr. 2 pieces of latex tubing about 2 1/2” long and 1 pc each copper and aluminum about 1 ¾” long rolled the latex tube back and then put it over the end of the metal tubing to form a somewhat square. Wore this for a couple of weeks and although it was more comfortable did not seem to notice any further improvement. Millimeter readings in the same range as before, so I filled it with a vinegar solution by using a very fine diabetic insulin needle and putting in a syringe of solution then taking out a syringe of air, took out the last couple syringes of air without putting in solution, caused voltage to jump to almost 2 but still no results and by now I was having dribble problems when I urinate again.
Decided perhaps I needed the separation of the tubing into smaller pieces, I cut 2 tubes each of copper and aluminum and 4 pieces of latex and made one, I immediately filled it with vinegar and still no results.
I put a pieces of tubing in my lathe and made tubes about 3/8” long, rounded the ends and deburred the I.D. And slipped three on each side of a ¼” vinyl tube with a string thru it with a loop in one end and a bead on the other end held on by a drop of glue. I LOVE IT AND THE RESULTS, wore it for over 2 months 24-7 including shower, took it off only for sex and to clean, cleaned the metal with jewelry cleaner about once a week and then rinsed with clear water and a soft brush to be sure all of the cleaner was gone so I didn’t get a chemical burn in the wrong place. I did occasionally get a very slight pinching effect where the bead and loop came together, something I did not have with the bow knot, the shoe string was starting to determinate.
Just made my last one and am wearing it for the second day right now, I made it from ¼ vinyl tube 6 ¼” long, 3 each copper & aluminum tube 3/8” long, latex tube in between each metal tube just as a filler for comfort, put a piece of 3/16 braided nylon cord thru the center long enough to tie in a bow knot, so far no discomfort at all. If I need, more changes, I have plenty of supplies but the way this is feeling I think I have it almost perfected.
