Geek99 Posted January 14, 2021 Share Posted January 14, 2021 I see the dust rack has been in action again @Andyjr1515 was “dust (ebony)” just to left of “dust (magic)” and “dust (pixie)”?

Andyjr1515 Posted January 15, 2021 Author Share Posted January 15, 2021 (edited) There are many tasks in guitar and bass building where I still haven't found the 'perfect' way to get things right or accurate. One of those is the short area of body wood that the fretboard sits on in the way that I do through-necks. If you remember, I cut a notch in the neck blank that the top slots into. The top face of this area is at an angle to the top face of the main length of the neck - and that's what will give me my neck angle to the body: But, because the fretboard extends over the body for a short distance - and is an an angle to the body - I have to take steps to make sure that the end of the fretboard doesn't end up with a gap. And so I set the body a couple of mm proud of the neck top face. And so I then need to cut an angle in the body wood to make sure that the fretboard is flat against wood all the way from neck to heel to fretboard end. And the challenge is cutting that angle. In the earlier days, I used to think just a levelling beam would do it. But two things tend to happen - the beam does quickly remove the edge of the body wood - but then tends to ride high over the body and leave a lump but also starts to sand the neck (which I don't want - as that is already flat). My present method is to take the bulk off masking the neck and pulling a fine microplane blade down gently across the body wood parallel to the neck top face, and then use the longest, sharpest chisel I have to go the other way - using the neck upper face as the datum for the chisel and slice away the excess, lumps and bumps in a sweeping movement up the body wood: It seemed to work. And why do I outline this in so much detail? Well, how else am I going to remember next time that this is how I did it this time??? The full length was checked with a straight edge, truss rod put in, back stop glued and it was ready to have the fretboard glued on: And it's clamped up and glue drying as I type: And that means that I can start carving the neck over the weekend. And all guitar and bass builders will tell you that neck carving is the most satisfying part of the whole process.

Jus Lukin Posted January 15, 2021 Share Posted January 15, 2021 Looking great, Andy! I've had some rather irritating things to deal with the last couple of weeks, so it's nice to add some positive adrenaline to the fight-or-flight stuff! Neck-carving- I'll get the tape measure out this afternoon! 1 Quote Link to comment Share on other sites More sharing options...

Got lots to still do elsewhere on it that I can still carry on with In the meantime, pleased to say that the joint looks good: No one panic about that dark line in the mahogany - it's a grain line, not a crack. 3 Quote Link to comment Share on other sites More sharing options...
Andyjr1515 Posted January 18, 2021 Author Share Posted January 18, 2021 Next big step is sorting the positions for the tuner blocks. The only sure way I know of getting the bridge units (or even a fixed bridge!) in the right place is to fit some old strings to the headstock and try it for real. It's relatively easy with this because the strings are clamped at the headstock : Then, with the tuner units positioned with a minimum of 5mm back movement from scale length, it was a case of pulling the two tuner blocks tight and positioning to be even either side of the fretboard and 54mm apart to give @Jus Lukin his preferred 18mm string spacing. Then I could mark the front screw hole positions for those 2 and then divide the remaining space for the other 2 : With all 4 front screws fitted, I could now string it up lightly and check the angular positions - they could be set straight (as, of course, fixed bridges are), but with single element bridges, I always think it adds a little to have them following the string line: Then I could fit the back screws to each of the four bases and...of course ... do a mockup. I've dampened some of the walnut to show broadly the colour it will eventually be. The fretboard also will darken from this: Next job is levelling and recrowning the frets and then I can see what my action range is so I know if I need to sink or raise the elements at all. And yes - this above is actually tuned to pitch and actually plays acoustically. Admittedly not a great sound...but, trust me, with my playing, a lot better than when it's finished, plugged in and louder And I love that Nova system. It just WORKS! 13 Quote Link to comment Share on other sites More sharing options...

SpondonBassed Posted January 18, 2021 Share Posted January 18, 2021 Andy? Have you any plans to make the cut ends of the strings safe other than cutting them as close to the clamps as you dare? I know from experience that, with headless, you can overshoot so easily if there's no volute and I'd worry about snagging myself on those as they appear in your recent photos. I'm keen to see how you finish the neck end. I'm gathering ideas for my own build down the line somewhere. 1 Quote Link to comment Share on other sites More sharing options...
MPU Posted January 18, 2021 Share Posted January 18, 2021 On my latest headless I made the neck about 15mm past the string clamp. When I cut the strings they were still over the neck and somewhat protected. 1 Quote Link to comment Share on other sites More sharing options...

I'm keen to see how you finish the neck end. I'm gathering ideas for my own build down the line somewhere. It should be OK. These are just rough cut old strings, I haven't finished sorting the intonation offset and the ebony end cap isn't sorted yet. Once the intonation positions are set, then I see no reason why the ends should poke out of the back of the clamp block at all. Having now put them on and taken them off pretty frequently as I was sorting up the fixings, I have found that it is exceptionally straightforward to push the string ends into the block and clamp them and it won't be any more difficult once the strings have been pre-trimmed. It'll look better too 1 Quote Link to comment Share on other sites More sharing options...
Andyjr1515 Posted January 18, 2021 Author Share Posted January 18, 2021 If I get time tomorrow, I'll pre-trim a couple of the strings and take some photos of how I string up with this system - it'll double as the 'How-to' that I would normally be doing for @Jus Lukin anyway Before I used these, I had the same questions in my mind, but now having seen how the Nova system works, it takes all the guess work out of it. 1 Quote Link to comment Share on other sites More sharing options...

Andyjr1515 Posted January 19, 2021 Author Share Posted January 19, 2021 (edited) For completeness and as a 'How To' guide for @Jus Lukin I'll confirm all of this when the real strings have been fitted, but this is how I would do it with what I've done with the test strings. Below assumes that the bass has already been intonated and therefore the tuner holders are already clamped in their playing positions: 1. Normally, the ball-end socket blocks are going to be in the right place - because normally you will have recently loosened the strings. But assuming that I'm starting from scratch, I would unscrew the brass block, then reattach and screw it on around 3mm to ensure that enough thread is in the block to start off with: 2. Then the ballend of the string is pushed through the tuner holder: 3. The ballend is hooked into the holder and the unit pulled into the holder: 4. The string is pulled straight, the position to the end of the clampblock noted and the string is clipped at this point: 5. The string is fed through the clamp block until the string is straight and then clamped: 6. String is tightened to pitch: I trimmed and fitted all four strings in less than two minutes. Oh, did I mention that I love the Nova system...? . Ref intonation, if you were, say, fitting a different gauge or make of strings, you would leave them overlength, tune up, check and/or adjust the intonation, then, when the tuner block was secured in its final position, just loosen, unclamp, shorten and reclamp.

Okay, next bass build will need the Nova system. This is a really smart solution. 2 1 Quote Link to comment Share on other sites More sharing options...
MPU Posted January 19, 2021 Share Posted January 19, 2021 I've used ABM, ETS, Hohner and Nova headless tuners. Nova is by far the smoothest and easiest to tune. They are also the lightest. 2 1 Quote Link to comment Share on other sites More sharing options...
