I've yet to finish my little 'Gingery' hand wave winder, made from scrap - yet another of my 'almost finished' projects. I was intrigued by the excellent youtube video which enthused me to make it.
All I need to do to finish it is to make and fit the wire guide - most of the work has been done. In place of the 'tally counter' I fitted as shown in the book as a turns counter, I might instead use a small pocket calculator. You then use either a microswitch or reed switch so that for each turn it shorts out the '=' key on the calculator. Then to start counting turns, you enter '1' twice for it to become a constant, then each time the = button is shorted, with each turn of the coil, the calculator increments by 1, counting upwards - 2,3,4 and so on. Not my idea, but neat eh - a turns counter for less than a pound. (87p at Tesco - cheaper than Poundland!).
All I need now is to get a 'round tuit' and I'm sorted!
