Haha well it did cross my mind :mrgreen:

But Colin only had one and I’m not buying any. He did have a few singles of various shapes so I could have gone random... now there’s a thought...

That looks great to me Adrian - it's amazing what sawdust and glue can do for you, isn't it? (answers on a postcard please, to the usual address ;) )

Wow that looks like a brilliant repair, I'd be very happy with that!

As an aside I've just done something similar to fill holes in brickwork. I've no idea why the previous owner felt the need to drill quite so many holes for a light fitting but with clear silicone and some red brick dust, much tidier.

It does look nice. I recently acquired an old 70s Fender 12 string from a local shop for a song. It needed a lot of work and like a lot of old mistreated 12s a lot of meat off the bridge.

The chisel slipped :? But on closer inspection it had formed the shape of a small almost perfect arrow-head. So I filled it with bone dust and superglue and it came up a treat.

So if you ever see a Fender 12 with a bone arrow inlay just below the bridge... that's mine.

Its a feature, as they say in the building trade.

It’s these ‘features’ that make instruments unique and interesting I guess. And at the end of the day it’s really about how they play and sound anyway.

December's workshop visit report..

Time to start fitting the neck to the body. First off I have to cut a mortice in the heel to receive the perch pole. After marking out the position I removed a fair bit of the wood using a forstner bit in a pillar drill, setting the stop for 20mm.

I then chiselled out the remaining wood until the perch pole fitted:

..and then test fitted the whole thing:

Then it was a case of slowly taking down the heel using whatever worked best (small plane, chisel, file), maintaining the angle as measured between the top and the sides, until the heel fitted snug against the body. Nearly there:

Image

It's just a case of test fitting, taking off a tiny bit more wood from the heel, or from any parts that are stopping the neck from fitting snug. Just a little bit more to do, but I ran out of time and I learned my lesson from last month trying to get too much done in a hurry ;)

Back to the workbench at last, having missed a trip in January.

Last trip I had got the heel/body joint to somewhere within spitting distance:

Image

I thought I wouldn't have much more to do to get the neck on, well I guess it's better to be optimistic otherwise I probably wouldn't have started this. However. The maple on that heel is like rock, trying to to take off small amounts in a controlled way is a bit above my skill/experience level. See how white the knuckles are:

But I got there in the end. Next thing was to see how it all lined up. I clamped the neck in place then screwed through the fingerboard into the block under the top. (Managed to drill through the fingerboard when I was recessing one of the screw heads so needed to patch that - ho hum).

Image

Then checked the centre line on the fingerboard to the one at the tail end of the body. Close, but not quite there:

Image

Another round of removing small shavings, filing, sanding, test fitting until it's all lined up. Great!

Now I had to check the action/neck angle. With the neck clamped in place I fitted the cone and spider and using a long rule between the bridge and the nut position measured the distance above the fingerboard around the 12th fret:

Image

I had just over 5mm, or about 4mm above the frets when I eventually fit them. Even though I want a high action for (mostly) playing slide that'll be too much once the saddle is fitted, even allowing for string pressure compressing the cone. The neck is too flat to the body, I need it angled back slightly.

So, another round of removing small shavings from the rock hard heel, filing, sanding, test fitting until I have just under 3mm above the fingerboard at the 12th. It's a judgement call at this point whether to take more off but I decide to go with it.

Finally, what's the scale length like? If I've positioned the cone correctly I should have ended up with 642mm at the saddle. Seems like a long time ago that I made these measurements...

Image

.... but all looks close enough. So Now I can glue the neck to the perch pole.

Just a case of using some epoxy to glue the perch pole to the neck and clamp it in place having masked off the body under the heel to protect against any glue squeeze out.

Image

I'll need to make a shim to go between the body and the fingerboard to fill the gap made by angling back the neck, and the neck/perch pole joint will need more support (more epoxy to fill gaps and screw up through the heel into the tenon), but hopefully that's about there now.

I found that pretty tough. Col said I shouldn't feel too bad, I'm doing something more complicated than a scratch build (wish he'd told be earlier). Having a fingerboard in place and that wood around the truss rod end makes the whole thing more tricky. Come to think of it, a few pages back in this thread Wonks suggested I could take the fingerboard off and fit a shorter truss rod. Might have been the way to go...

Surely you want the spider slightly angled so top E is nearer the neck than bottom E to get a reasonable intonation? Which might mean that the spider is a now a bit too near the neck if the scale length is correct in the middle? And you'd normally need a longer length than the nominal scale length.

For a 642mm scale length, the StewMac calculator gives the nut to saddle distance of

Treble "E" or 1st string: 644.238mm (± 0.5mm)
Bass "E" or 6th string: 647.402mm (± 0.5mm)

...which is approximately a 3mm difference at the two E positions. With heavier strings (which you'll want for slide), then the bridge will need to be back a little bit more.

If you play purely slide, then it won't matter too much as you can compensate for distance and angle (though it makes it harder work). But mix some slide with some fingered notes and you really want the intonation to be as good as possible.

From the photo, it looks like that it's about 5mm too short a distance from the nut to the leading edge at the centre of the spider.

What you don't want to do is glue the neck on now and....

Oh. :o

Pass!

I've got a couple of mm wiggle room on the cone position if I need it, and the contact point on the saddle can be adjusted a little. But it is what it is at this point, I'm just going to have to go with it for now and find a way to make it work :)
