I've taken a fretboard off a couple of times. It takes care and patience but it's possible to do. I should have some photos somewhere. I'll post something in the morning with some hints and tips

Basically yes I used to cut away the shielding to glue them onto the wood but came to the conclusion they stick better to the shielding. I use gel superglue and then a light surrounding of epoxy for good measure. To position them, I put a bit of paper packing over the body magnet (which is set in about 1mm) and pop the lid magnet on top. Therefore it is in the exact position and standing a touch proud. I pop a spot of ca glue on the top face and then press the cover in place and hold it until the ca glue has set. I lift off the cover complete now with ca'd magnet, remove the paper packing then repeat with the next one. This way, all the hatch magnets are in exactly the right place without the need to measure anything -
You have my sympathies! I'm sure I spend more time hunting round for things I know I have somewhere than actually building!!

This a bit better, @Si600 ? And now you should be able to see the tiny angle of the bridge towards the stoptail at the bass side. Tiny, but it gives me a couple of mm safety factor for different string gauges, etc Other jobs today, I epoxied a couple of carbon rod stiffeners across the grain on the hatch to make sure it stays completely flat: Then copper-foiled the chamber and hatch and added the bottom magnets: Next job is fitting the hatch magnets and then that's down to just 4 things still to do -

What - that I am going mad? That bridge, as well you know, Simon, was crossed many years ago... I'd have spotted it eventually anyway and it's a super-easy fix. -

Re-read, @Si600 and promise to pay more attention next time The bridge itself is skewed and that should be. But yes - the bridge surround is also skewed...and that shouldn't be I skim read the posts because I was actually pm'd about the bridge and assumed that the other comments were also about the bridge. So, just to clarify: Yes - the bridge is skewed on purpose = Andyjr1515 is a great builder and knows what he's doing and Yes - the bridge pickup surround is also skewed, but in error = Andyjr1515 's work has been found, quite frankly, wanting and he should have gone to Specsavers (if they'd been open) In my defence, there is a bit of an optical illusion too - the two pickup rings ramp up from 1mm thick for the edge of the neck one next to the fretboard, all the way to 10mm for the edge of the bridge one next to the bridge. And the ramp is casting a shadow. But it is undeniably about 1mm out of square. And it will, of course, be fixed OK - that's quite enough c**kups emojis for one day -

No - your eyes are fine. I've never explained that and it's never occurred to me that basses rarely have the issue. Yes - as @BreadBin says, the bridge is intentionally out of square. This is actually less of a tilt than the original Gibson because the bridge I'm using has more adjustment than the original Tune-o-matic - but it is tilted nonetheless. Basically, the bridge design isn't wide enough to be able to adjust for the intonation, so the bridge tilts a bit like an acoustic guitar saddle. -

And another one ticked off the list. I popped a couple of P Rails into the pickup rings (Matt will be supplying his own pickups) to line everything up. The strings, again, are just for lining up - they are a set of flatwounds I tried on Pete's piccolo bass build a few years ago. The P-rails are useful as one of the tasks was making sure that the pickups fitted and adjusted in the chambers and the coils of the P-rail are just a touch fatter than most humbuckers - so this should be worst case. Spent quite a bit of time chiselling out the tight spots. These now adjust fine, so I am happy that Matt's will also. And that leaves 5 jobs left on the list -

And a couple more jobs off the to do list. First of all, drilling the bridge earth wire hole and fitting the earth wire. I talked about a tip to get inserts out. A bolt would be better, but I found that the screws they use to fit bed heads to beds are the right thread So with great care not to let the screwdriver slip (which is why a bolt would be better) I screw it in until it bottoms at the wood inside the hole: And then I just carry on screwing. The bolt can't go any further down, so the insert has to move the other way: With the control layout paper template, I mark the points from the insert hole to where I want the earth wire to come out into the chamber: I draw a pencil line joining those points on the other side. Then get a very, very long bradpoint drill and line it up with the line. Theoretically, it has to drill through the insert hole. Always a relief when it does, mind you And then simply push the earth wire through, with a generous length stripped of insulation, and just re-insert the insert, trapping the copper of the earth wire as it does so. Finally, drilled the recessed hole for the tele-style jack socket I am using: Just 7 items left to do -

The SG has quite a cramped controls cluster. Some of that is the body shape, and some the fact that they have a top-mounted jack. While I can't do anything about the body shape, I do have the advantage of going for an edge mounted jack. I'm sure there are lots of other ways of laying them out, but after lots of mockups, sticking the knobs and tip on with blu-tack, this one below passed my 'air guitar test' of ensuring I would never accidentally hit the switch while flailing my arms Pete Townsend style, but could still reach both or individual volumes quickly without hitting either the tones or the switch. I tried with the switch position a little further forward but came to the conclusion that it is safer from accidental adjustment here. So it's still tight, but I think is going to work OK live: Inside, I wanted to leave most of the chamber bottom thicker than the pot spindles to maximise the stability in that knotty area, so I just Forstner-cut some recesses for the pots and switch to allow good thread access the other side: Once I've cut the jack hole, I'll tidy up the inside shape to make it look more like it was supposed to look like that -
How to Remove saddles from piezo bridge
Andyjr1515 replied to derreybass's topic in Repairs and Technical
Hi, Derrey @ikay might be right. It is possible they are just push fit. The units themselves will be sealed in plastic so if a paper clip will go in (or the blunt end of a sewing needle) a gentle push will soon indicate if they are going to push out and that won't do any harm. If they seem firm, then they are probably superglued and won't be coming out. -

Another two jobs off the list - fret levelling/recrowning ; fretboard tidy-up. And another shout here for Chris Alsop Guitars - after levelling with my 1m aluminium beam, I used one of his whole raft of really usable and practical tools - this fret recrowning file: It is a good radiused diamond file housed in such a usable handle! Easiest re-crown to date. I did the normal marking the flats on the frets with a sharpie and then used Chris's file first on its own, then with 320 grit sandpaper wrapped over the file, then with 800 grit sandpaper, and finally with 3200; 6000 & 12000 microweb cloth, again using the file as a radiused sanding block: Then used a single-edged razor as a scraper to tidy up the fretboard. It's come up nice: -
Exciting! Hmmm...multi-scale...fretless...led's...multi-piece neck I can see that my "he's the guy who takes on the crazy stuff" crown may be slipping soon.

I'll sand these fully flush when I tidy up the fretboard and give the neck its final oil and buff after fret levelling, but the mother of pearl fret side dots are in: That's another one ticked off the list. Just 11 things still to go -

Not quite right. It is the bending of the string, albeit vertically, to reach the fret (or in a fretless the fretboard). So if you have a high nut, your bottom frets will NEVER sound in tune because the string is bending and therefore tightening out of pitch in trying to press it down to the fret. So high nut, low action - it will be in tune at the upper frets and out of tune at the lower frets and low nut, high action - will be in tune at the lower frets and out of tune at the higher frets. -

Basically, yes. In most cases with most bridges, wind the G saddle fully forward and fix the bridge so that the peak of the saddle is at scale length (yes - I wind back a couple of turns because I know how inaccurate my work is.) But before you drill holes, wind the bottom E saddle fully back (allowing for string windings too) and double check that this gives you at least 5mm longer than scale length, which is typically the maximum you are likely to have to lengthen beyond scale length to intonate the bottom strings. If in doubt, put an accurate long metal rule to the nut of one of your fully set-up basses and note where each of the saddles are sitting in relation to scale length. The thinkers amongst you will come to the conclusion that the only place that the string is going to actually accurately intonate is at the 12th fret. The reality, of course is...yes... I've said it before, basses and guitars are a series of compromises held together by hope... -

You need to know that with the bridge fixed in a particular place, that there is enough backward movement to intonate the most affected string (which is usually the Low E). But the amount of movement of the saddles is sometimes barely adequate and so, if the top string saddle is as far forward as possible when you fix the bridge, then if gives you the maximum amount of backward movement. On this one, there is only just enough movement - so if the bridge is even 0.5mm out, then you could get to the stage of not being able to intonate the bottom E...which would be upsetting. And so the bridge (as with most SGs and Les Pauls) is angled slightly, pivoting from the top string saddle position to ensure there is a safety factor and, regardless of the string type, gauge or action height, it is always going to have enough backward movement to intonate. Re-reading my poor explanation, I can see I might have to draw it!
