I finished refretting this guitar today at lunch. In total both days to plane the neck, install the frets (only one wobbly and rather than to fix it, I just remade it).
I'm less inclined to sell this guitar quickly now . The stability of the mahogany neck (which usually presents needs for significant work in a one piece mahogany electric guitar over what's probably 45 years in the case of this one) gave me a bit of a distaste for the guitar, but for what it cost to fix ($10 in frets and figure $5 of consumables all told), Now I suddenly like it.
The pickups are high quality and it looks like the pickups and the case by themselves would sell for near the street price of the entire guitar in japan.
It is pancake, though after staying away from pancakes because the internet said to, I'm more in favor of them than multi piece bodies with poor matching. The pancakes are well matched and the boards are dead quartered, straight and ribboned. The neck was the only real issue and now that's fixed thanks to some poor man's skill.
The frets are good enough to go and if needed to be made more perfect for the picky with a specific end treatment, there wouldn't be much to do.
Here's my regimen, the end part with the fingerboard is probably important:
* flatten the frets with a file glued to a board (figure about the size of a mailing envelope)
* file (with an older regular fret file, not a diamond fret file) crown into the frets - the older files can leave some chatter in heavy cuts, but they're fast and the file that I use is cheap.
* coarse sandflex block on the frets, but a bunch at a time, gradually moving the sandflex around
* 400 grit paper on the sandflex
* then a little automotive touch up handled thing with hook and loop - 1000, 5000, 10000. The amount of time spent after crowning to have the frets functionally polished is about 10 minutes. No taping off
* then when done, linseed oil (on rosewood) and p-1000 broken in used laterally all the way up to the frets to remove any small marks and cake the pores a little (I know this isn't typical)
* then one more shuffle with the padded disc across the tops of the frets in case the sanding left a stay bit here or there, and wipe off any excess oil or black stuff.
Out of pure luck, the nut was probably never filed lower on this guitar when the frets were redone. The neck was too far out of straight to ever notice. Now with frets installed, the nut height is ...like collings.
This guitar is made with more care and feels better than the early 2000s standard that I had as my first les paul, and it's a little better than the HLS tokai. Bonkers that the market things a 70s les paul is $3500 now and this guitar is $600 in japan. It's a better guitar.
it's 9 lbs 5 oz, uncanny les paul sound, too - as in, not obscenely heavy, but very robust. The neck profile is divine, but I find that to be the case for most japanese stuff that doesn't have an outright flat (stylish at the time) thin neck.
