Jon's 4th build: SSCM-1E

The all black is looking very nice. Great work.

By "side to side" do you mean across the width of the fretboard?

I do. There you go, I didn't realise that "up and down" is the way to do it. I'd have thought that would be more likely to end up in flat spots, which is probably why I'm going side to side. Also, I'm using sandpaper attached to the straight edge on a spirit level - are you, or are you using a radiuses block? What issues would you see with the side-to-side method?

I use an 8" steel levelling beam as I find it better than radiused blocks. I only use radiused blocks for sanding unfretted fretboards. Some prefer a longer beam, but the 8" works for me. Others will use a diamond levelling file which are only 6" x 2". Not right or wrong, just personal preference and what works best for you.

edit to add:
I like the steel beam because it's quite weighty and requires no downward pressure, just the weight of the beam is enough.
All I need to do is direct it along the fretboard with my hand(s).

As for lengthwise vs side to side, lengthwise encompasses all the frets more evenly (your passing over all the frets with each stroke). Think of the way the strings actually run along the fretboard.
Going side to side you're only passing over say 10 frets at most (presuming an average sanding sheet being 280mm) then when you move up to the next 10 frets, there's no contiguous relationship from the first 10 to the second 10. Potentially you could end up with two groups of frets at two different heights. Clear as mud, right???

Kind of a crappy explanation, but hopefully it makes sense. Maybe someone with better "word skills" can offer a better description.

Thanks McCreed. I'm starting to realise that my fret levelling and crowning game's been a bit hap-hazard to date ;-) The kits I've built so far have come with pretty good necks, i.e. aside from some frets requiring a little tap here and there, the neck's been straight and the frets have been pretty level.

I have just checked the board again with my notched straight edge, and the bow towards the nut appears to be significantly reduced - the gap's still there, but down to a fraction of a mm. The guitar's been strung for the last week or so, so I'm guessing the string tension has more-or-less rectified the situation. I am still getting a lot of fret buzz with strings fretted at the 1st, so I will need to have another go.

I was going to add this as an edit to previous post, but I'll just put here on it's own.

The the only time I work "across" a fret is if I'm just doing a single fret (eg: say I replaced 1 fret and need to take it down to match existing frets - like I did on my current build) or if there are a few frets (that aren't consecutive) with varying high spots.

There are plenty of times when a neck just needs a little fine tuning rather than a full levelling. I have a friend that's a highly experienced builder and he does this type of fret by fret levelling exclusively. That's what works for him.

Nearly finished!

My second attempt at fret dressing was much more successful. I did have to take quite a lot of material off, which left some quite wide flat tops to the frets - they're fine after crowning. The guitar plays much better now. I still need to dial in the set up (haven't looked at relief, intonation or action yet.) and finish the electronics.

[McCreed]

Wow, that's truly a mirror finish! Nicely done.

I recently did a drop-fill repair on a black polyurethane (factory) finish and I now know why people say solid black finishes are the hardest to pull off (and apparently solid white also). That was enough for me! I don't see any black guitars in my future.
Good on ya!

[jonwhitear]

Thanks McCreed. I am very pleased with how the finish turned out. It's certainly been a steep learning curve, and I've forgotten how many coats I've sprayed on and sanded off. It seems you can also scratch black paint just by looking at it.

[jonwhitear]

Well, I'm calling this done (enough).

I spent most of Saturday regretting my decision to make the electrics as complicated as I could just for the hell of it, but after a few cycles of fixing and reassembling, only to find something else broken, it's finally all together and working.



It has a push/pull coil split on each volume knob, and a push/pull blower on each tone (I think that's the right name for it - it bypasses the volume and tone controls.) These pickups and the wiring were transplanted from my AG-1, so I'm used to the sound, though this guitar is more resonant unplugged.

[Trevor Davies]

Great result. Looks amazing.

Thanks, Trevor.
