Making a Tapped P-90

[big_teee]

I have been asked to price, and consider making a Tapped P-90?
He wants the first tap to be at 10k turns, and the second to be hotter than hell.
I told him I thought it not practical, but I said I would look into it and think about it.
I am not considering a bobbin made from forbon, just using a conventional plastic bobbin.
Anyone got any simple ideas?
Or think like me, it's not worth the trouble?

10k is already smoking hot! It would be interesting to find out why he wants such high output. If he is playing high gain music the noise from the amp would be tremendous! If he just wants to roll off highs using 2 A2 magnets would do it. In the LP carve top my secret formula is A2&4 in the bridge and A4&3 (or 2 and a short 5) in the neck. I have a patent applied for on that lol.

Maybe try and sell the idea of a 10k pickup and have him look at a Bearfoot Red Rooster Booster #3 or an Effectrode Fire Bottle Booster to get mega output.

This is a Luthier that was wanting a tapped pickup for a Guitar in progress.
He wants a reduced P-90 for the neck, and the tapped for the bridge.
The guitar is near completion, don't know if the switches are routed or if he was going to use a push pull?
I suggested a P90 in the neck, and my hot Humbucker in the bridge, and split the humbucker.

I've never wound a p-90 to 10k using 42 but you should get there no problem then use smaller gauge wire for the second tap .
If you worried about flaring ,A stiff piece of metal or wood mounted with your mounting screws or another bobbin will help ..
I have wound high output p-90's but not with 42 gauge wire.

Sorry, that is 10,000, or 10k turns not DCR.
He wanted 10,000 turns on first tap and more on second tap.

Oh Sorry I meant 10k dcr
10000 turns is about 7.8k then you could go 10600-10800 or higher for a hotter more midrangy mountain tone which will be in the 8.7k +/-

Wind the first 10,000 turns with 42, and then switch to 43 or 44 for the rest.

The issue is not how much to put on?
But how to do it feasibly?
I looked at lots of pickup sites no-one sells a tapped P-90 that I could find.
Everybody and their brother sells a strat, and tele tapped.
you just put an extra eyelet on the bottom forbon.
Don't know how you would do that on a plastic bobbin P90?
That is why I told him I didn't know how to do that on that bobbin type.
I suggested a Humbucker in the bridge, and just split it with 4 wire hook-up.
So that is the Question, is How to do that easily on a plastic P90 Bobbin?

At the risk of getting stepped on for my inexperience (which I expect should happen so I can learn a bit more), why not use a forbon bobbin? It would make dealing with tap wire coil end eyelets easier, and you could put more wire on the bobbin as the space taken up with plastic "core" space of a plastic bobbin is available for coil wire.

I looked over a plastic bobbin, and I think it looks doable.

You using the mojo p90 bobbins?
I recently made a set from those and used eyelets, I'm sure you could drill an extra eyelet hole in the plastic.

In fact, cutting down one of those to fit one of those plastic hum cases and drilling holes for eyelets is what I do for hum sized p90's.

There's a problem with the plastic bobbins and using eyelets.......

Yep, if your iron is too hot it'll melt the plastic, which is what happened on my first try.
Its no different to me than trying to use a guitarpartsusa bobbin or an American fender bobbin.

The few times I've tried soldering to eyelets in plastic bobbins I can't seem to get the temp just right as I always end up melting the eyelet into the plastic. Just need more practice I guess.

Temperature controlled soldering iron is a must.
I turn my temp down so it's just hot enough to melt the solder.
If it takes more than a couple seconds, pull the iron away or the plastic will start to melt
