Build 2 - Dan's LP JR Double Cut


Recommended Posts

Not a huge amount to report this week, a few little jobs that needed sorting. I finished off bevelling the fret ends that I started last week. I filed off the ends of the frets level with the edges of the board. I took the back of the headstock down to final thickness. I trimmed the sides of the neck within a gnat's nadger of the fretboard.

Nothing worth taking a photo

However I'm now all ready for the best bit next week - neck carve! :)

It's here! It's neck carve day! 🤘

Just a rough carve for now until I make some templates 

I started with a facet using my shinto rasp

then smoothed it out a bit

following by the heel using a chisel and mallet

and lastly a slight tidy with a half round file (I'm not sure what type, but it's darned efficient!)

and the volute

Your neck looks like mine! I mean the ones I've carved, that is, not the one my eyes can't see. No matter how much time and effort I put to shaping them, they always have a flat centerline. Then again, there's a reason for classical guitars to have a flatter neck so that obviously is an ergonomic decision.

The biggest issue with that is that although my friends seem to like them for noodling, they aren't perfect for the palm and thumb muted chopping - the only style I'm at least decent...

Anyhow, nice job!

This is a first rough carve. There's a good 2-3mm to come off the centre line yet and a lot of rounding over. I'm going to sneak up on the final dimensions gently, as Dan wants it to vintage spec (or whatever passed for a spec in the hand made days of '58). There isn't a huge amount of wood-that-isn't-part-of-the-guitar on the stock I used - it means little waste, but not much room for error

Yesterday I put together a quick neck carve radius gauge ready for this evening. I scanned the main plans onto the computer then used Inkscape to re-draw the curves. With a bit of manipulation and arranging, I printed, laminated and set about it with the xacto knife

So then I rough carved around the 1st fret (as seen above) and the 12th fret, then joined them together - all with the trusty shinto rasp

After a bit of scraping, filing and sanding, we are now about 0.5mm over the radius of the '58 spec. It feels a chunky neck at the moment! There's still a bit of sanding to do

Finally, some tools of choice...

Concave cabinet scraper and a 120 grit sanding block/level

The vicious half round file I mentioned the other week

It certainly has some bite

that looks like the Iwasaki file, I've got one of those and since purchasing, the saw rasp hasn't been used. These files are just awesome. Build is looking great - especially good job on that neck heel considering it's already attached. I've run out of likes, otherwise I'd give you a big fat like!

Thanks. I might take it back a bit yet. It's finding that balance between stability and access to the top frets. There's more work to be done, but I'm happy with the second stage carve. The sides of the heel will be the trickiest bit

Looking at how your neck evolved I think I'll have to get me a serious file or saw rasp and redo my necks as they really seem to have the same shape than your roughly carved one!

I made a load more sawdust tonight. Using my favourite 'D' shaped piece of molding wrapped in 40 grit bonded paper...

I refined the heel a bit...

20190610_214005.thumb.jpg.0a73d5076c4bd63d7444dc8ece131bf4.jpg

and the headstock transition/mini volute...

20190610_214017.thumb.jpg.7f36fc89cf037f5af74984785f03ecf2.jpg

Then I set about the neck with my 120 grit sanding block

That's pretty much the '58 spec I've got. It's still quite chunky, so I'll let the future owner have a bit of a feel before taking any more off

Tonight I did the roundover on the body. Mostly with the router and roundover bit, but then a lot with a quadrant cabinet scraper and sandpaper. Obviously a lot more sanding to come.

In other news, we had agreed on a Pelham Blue finish... scratch that. He now wants a natural "furniture" wood finish!

So tomorrow we'll discuss shellac. Shame, as I was quite looking forward to a bit of spraying metallic
