 "Smooth, faultless build". That must surely be utopic...  😉

I'm not convinced that its even possible.

 

Where would be the fun, the challenge, the satisfaction if we knew a build was going to be faultless? It'd be like doing a crossword puzzle when you've got all the answers in place of the clues.

Another delay in fitting the hardware, can't find it. Searched the shed, house, garage and car last night, its not at home. Its got to be in the caravan somewhere, thats me back in limbo again.

We could all send our spare parts up to you to fit?

 

You could make a 4 pickup, 5-string guitar with 1 volume and 3 tone pots and 2 bridges …

That would be very kind, but I'll just bide my time, get back to the caravan and find the bits once we've got dentist, childbirth and hairdresser dealt with. All three unrelated and not necessarily in that order.

Make sure you get the hairdresser done before the childbirth.

 

You don’t want to be having a bad hair day on all the grandad-holding-the-baby photos.

Good news, found my hardware, turned out that it was in the bottom of a box that I hadn't looked looked in because "I wouldn't have put it in there"

20230910 154527

 Thats the electrics ready to be pulled into place.

20230910 191931

 And thats it assembled. Unfortunately it only works when switched to the neck pickup, no sound at all when switched to bridge or both. It was working fine before I took it apart after my trial assembly before I put the finish on it. The only part that I had unsoldered was the neck pickup to feed the wire between the two cavities. So tomorrow's job is to take it all out again and find out whats wrong. I need something to do anyway while waiting for the birth of my granddaughter, ten days late now.

ten days late now.

And in this heat too - ouch, that's going to be "uncomfortable".

 

Congrats on the second practice run at getting it all into place ... third time lucky?

@robin sounds like the switch is dirty, before pulling apart try some violent switching or switch cleaner then some violent switching. Bad switch is the only thing that makes sense otherwise the neck would still work in middle position.

 

That's what my logical brain says anyway lol

Could be some loose wiring as well, I just had to repair someones LP copy , I switched out the old pots but used the original wiring. He came back to me, a few days later, telling me one of the tone knobs did not work  anymore.
Turns out, the wire broke off right at the point where the insulation ends. 🙄 

Weird thing was, it did work when I tested it. So it must have happened while I put back on the knobs or the guy just treats his guitars violently 🙂

@nsj  @koendb

I'm thinking the same way as you both. I've tried giving the switch a good wiggle with no effect. I'm guessing there's a hot wire on the bridge pickup circuit earthing somewhere, i think that would kill the neck pickup in the middle switch position. I did have to poke around a bit when I pulled the switch into position as my pulling ribbons got a bit tangled.

Still haven't got the electrics working, had the harness in and out another couple times now. There's been various faults, I'd broken an earth wire  off one of the pots, a tiny bit of solder between terminals on the selector, a hot wire earthing inside its shielding. Thi time I'm going to resolder every terminal.

The good news is that baby has arrived. After being 11 days late, she didn't hang about, little Ella arrived 40 minutes after getting to the hospital. Mother and baby both well. Now that I can stop worrying about my daughter and baby I can concentrate on making this guitar work as it should. I'm a proud dad and grampa.

Congratulations grampa @Robin!  Wait a couple of years and get the littl'un to sort out that wiring (they have smaller fingers, easier to fish around inside a hollowbody).

My first grandchild is just over a year old now.  Walking & talking (ish) and generally a happy little thing.  Enjoy these first days and weeks.  Before you know it, they'll be asking you for lifts home from the pubs & clubs ...

Thank you all for your kind words. We're back at the caravan now, popped in to see Ella on our way past, she's the cutest little thing. Back to guitar electrics tomorrow.

Well the guitar is all back together again and working. There seemed to be a random earthing problem and some tremendous hum. Eventually switched off the laptop charger, that had me going for a while, considering I had remembered to switch off the soldering iron this time. Also stripped out the shielded wiring and replaced with non shielded. I checked the pots with a multimeter, I've got two A's and two B's and they're all exactly the same, all four are logarithmic, that surprised me. I found one B in my box of bits thats linear. Do different manufacturers use different coding.

@robin As usual there is a US standard and a rest of the world standard with pots. US pots often use A for LOG and european standard use A for LIN instead. You did the right thing - measure the darn things.

@swepri never seen that yet, I've used all sorts and every A has been audio taper and every B has been linear. Are you sure about the US Euro thing?
