Remaking The Horseshoe Bass Bobbin

[badeggs]

This is so cool, great work man!!!

[johnallg]

Koji, this looks very nice! Are you taking orders for the bobbin assembly?

I will be the first to request sound samples when you get the pickup wound and into the RM1999.

What gauge wire will you use and what ohm reading will you wind to?

[Moonie Man]

Many thanks for everyone.

When I said honestly, it tried in order that I may commission this project the specialist of a certain U.S. at the beginning, but since he was not so interested, I decided to do by myself.

Sean(Mr. Kelly), I also knew the thing in which Sergio's pickup is popular at the members of this forum.
Your pickup and are wonderful!

John(Mr. Alligaier), How do you think about the type of coil wire(types and gauges) for winding the Horseshoe pickup coil?
I have plan to choose 42 AWG Plain Enamel Copper Wire for winding to my bobbin since I would like to pursue the vintage sound.
My target DCR is 6.3k to 6.8k ohms at about 8,000 and more few turns.
However, I think difficulty in choosing the type of coil according to the tone and sound character.

John Hall has stated a couple times that the only wire they ever bought for coil winding was 44 AWG but the lapsteel bobbin I have has closer to 42 AWG on it. The 1968 hi gain coil I have had a look at also looks to be heavier wire than 44 AWG. Since you are doing this yourself, I'd wind with what you plan to use and to the 6.3 - 6.8k range you state. I nave modified an earlier higain bobbin (the circuit board type) to make the gap about 3/16" because I have a set of shoes that are not opened like yours, but the two sides of the C shoe are parallel. I have a bobbin of old 42 or 41 AWG wire around here somewhere to wind with but so far I haven't found where I put it away for safe keeping. I too plan to wind to around 6.5k.

John, Thank you for your reply. It is a good reference.

Also, if I making the bobbin of some versions it can be hearing and comparing the difference in sound according to the kind of winding of a coil...this becomes a slightly extravagant plan.

This is for my first trial, I will order the 42 AWG Plain Enamel Copper Wire anyway.

Keep us up on your progress.

Wonderful. I love do-it-your-self project.

For your reference;
The 7.4K scattered wound toasters have about 5500 turns (I've counted).
I wound up a reissue horseshoe bobbin with 5500 turns, and that gave 8.1K (with 44 AWG). Estimated 7500 windings on that horseshoe bobbing would end up around 11.5K, so I believe reissue horseshoes probably have 7000-7500 turns.

8000 turns might be a bit high for vintage tone, but why on try. You can always wind it down again if it's too much.


Btw: Curious about you method of winding. Would be great to see some photos from the winding process also.

[Seans]

I recently wound a normal non HS pup for my 72, using 44swg, I wound 10 coils, measured the resistance and got 11 ohms (roughly, could have been 10.5), so that was 1.1 ohms per revolution, I then wound 8500 coils which is roughly upto 9.35K tops, I was aiming for 9.5K and got an actual 9.6K, taking into account the increase in ohms per coil as they get longer.
I think with the new HS the bobbin size is much greater, so one could be on 1.5ohm or more per wind.

Geir and Sean,
Thank you for the information based on your experience.
Your information is great helpful for me I will refer to it.

I have already ordered the 42 AWG coil wire today.

I have just been going to begin making of a coil winding counter now.

It is originally just a Handy Walking Step Counter I have bought that was ¥100JPY(about $1.30USD) only!
With a little modifying to that tiny walking counter it can be able to the coil winding counter, it is so easy job and a wonderful thing thought it just suitable to my project!
It is a very healthy gadget to my budget too.
I am enjoying in this D.I.Y. project.

[BAD RONBO, KiLLeR DWaRfS]

mine's a mechanical counter with trip arm and reset i got when i worked at a max factor factory in toronto iin the late '70's. every time the coil came around , it would count off a mounting screw. electronic is the way to go.

[chefothefuture]

This is a silly question; I should know this....
What size screws are you using? 6/32 ?
I was going to order some and I can not remember the size Rickenbacker used.

Nice work by the way. Yes, are you taking orders? LOL!

Smart


Here is my winder. I sneak myself to use it when the "boss" is not home. (Hope she doesn’t see this )

[Moonie Man]

Ronald, It has not felt like the ability of me to trust the direction of a mechanical counter rather than an electronic thing, either.
Although the thing of the system which resembled it with the electronic type could also be made, since it was troublesome, I decided to use a simplest and cheap thing this time.

John(Mr. Fay), It is not a silly question at all.
I have used Fillister head machine screws for the pole-pices of my bobbin, size is: #5-40 UNC. It is just same as replacement of Humbucker's.
For your reference: http://www.allparts.com/Nickel-Humbucke ... 53-001.htm
However, I cannot declare correctly whether it is that Ric was using the exact same screw for the Horseshoe Bass Bobbin as this.
For the moment, what I will make my bobbin in response to an order is not considered because I am not a professional pickup builder and I am only an enthusiast.

[Moonie Man]

Wow!
Your winding machine is nice, Geir!
I felt your personal character familiar.

[Moonie Man]

Geir, I also feel like seeing a face when your wife finds that.
