Hi All. I'm busy trying my hand out at building a 3-pole single coil pickup for my next CBG (probably a Steampunk). I have started the construction of the bobbin and am using 3 Alnico 5 pole pieces. I have built a jig for putting on the 42AWG copper wire onto the bobbin. I bought a Chinese-made magnetic induction LED counter to count the number of turns. Has anyone got experience of building there own 3-pole single coil pickup and do you have some words of advice? Many thanks! ... Ian
I made my own pickup winder with a sewing machine motor and found that it was very easy to out-run the electric counter, so I added a mechanical counter, belt driven off the drive spindle which is much more accurate. The photo is just after I made it, there are a few modifications including the mechanical counter which aren't on that shot. There's a knack to getting the tension right when winding and it does require a fair amount of patience to deal with the occasional disaster when the wire breaks mid-wind.
Brilliant! Many thanks Chickenbone John for the valuable information and the photo. I see that you used exactly the same magnetic induction sensor and counter that I have just bought from China! Interesting that sewing machines have always had the facility for bobbin winding and at a reasonable speed. My attempt uses a Bosch corded drill. However, I think at the slowest setting it may be a little too fast! I shall give it a go and see what happens. My first bobbin is a little small for the amount of turns that Ideally should have. I offer you this photo. I do follow your YouTube tutorials and extremely good they are!!
Take your time, do not rush or you can guarantee that wire will snap! I have never used a counter, just trusted to luck that I`d count it correctly. If you get anywhere near to the turns you are after and get a break don`t try to fix it but just go with what you have. You usually find what you have is more than good enough once it`s plugged in. My pickups have all been hand wound so it does take an age but, to me, it is very satisfying. Make sure, before you put your wax finish on that you get the plus/neg wires exactly where you want them and that they are properly secure.
I know a lot of people use various winders but hand wound, although taking a while is satisfying and, in reality, doesn`t take that long! A hand wound jig does sound a good idea though ;)
Hi T-Belly. Appreciate your wise comments! I will probably only get to about 10 turns before the wire snaps but will persevere! I can't imagine how long it has taken you to hand-wind a bobbin with say 7,000 turns! Although you say it is very satisfying you must be extremely patient! Thanks again for the tips. bets wishes ...
