Amazing! Glad to see it's still underway! I'm Jonesing for one of these now. I was having talk with a local guitar tech in his shop and after about 20 minutes when I proved I knew my stuff, he brought out his collection that included '62 jag, but also a '65 SG-3. It was beautiful and sounded amazing, better than the jag! It had the old script logo and everything, I'm really digging them now.

Really want to see this finished.

Welcome back, I've been missing your build threads. This is shaping up to be a beautiful guitar! Noticed your pic of the fret slotting done in the sliding compound mitre saw- I do the same- quick, easy and you can see what you're doing. 8)

Cheers guys!

Should really have fretted it first, but I had a good stretch of daytime free today and wanted to get the back of the neck carved. In my new spirit of jigging up, I figured out a way of doing the bulk of the work with my router. This might need some more work to get it a bit more adjustable and robust for future builds, but it worked better than I'd hoped on this one.

First pass with the cutter as low as it will go without nicking the template:

Image

It actually makes the earlier set-up for cutting the thickness taper pretty redundant - I'll know for next time. I put a bearing on the shaft of the cutter and made a template that sits under the neck - the bearing on the tip of the cutter is useful for setting up, but doesn't do any work.

End result after a second pass at the right height:

Then I bolted it to the counter and cut the transitions by hand. I have a newish microplane rasp that worked really, really well for this, finshing off with a half-round file and sandpaper:

Image

All done:

Image

A slight misalignment with the router jig put a little nick in the binding between the 2nd and 3rd frets. Something I want to find a way of anticipating better next time. I melted some binding shavings into solvent-based adhesive to form a sticky paste and slapped it on. I'll scrape/sand it back down once it cures.

Neck thickness is almost exactly what Michael measured for me off his original SG-3 - about 21mm at the first fret, 25mm at the 12th.

Hi, impressive work !! ;D
I will be following this thread!

I have had similar ideas for carving the neck.
I suppose maple is pretty hard for router work...
What radius for the router bit did you use?

Spent some time on the second (SG-2) body today.

The bulk of the routing was the same as the SG-3, but when I got to the top cavity I had to improvise a little to make sure the rhythm circuit would fit properly. When I had all the original templates cut I included an SG-2 pickguard but never bothered with the upper cavity. I ended up making an MDF template for those bits:

Image

All the cavities done and the rough cut of the roundover:

Image

Couldn't resist a quick mock-up with the guard template and an SGV bridge:

Image

Also, I've taken apart the trem I was so generously donated. It's a serious piece of engineering - even disassembling it took some working out. I've staightened out some kinks and dents here and there, and now all the visible parts are going off to get stripped and re-chromed at a specialist place in Lewisham. My local chrome plater isn't really geared up for fiddly stuff.

Image

For those who asked the radius of the bit I used for the neck carve, I'm pretty sure the radius is 7/8"

That neck "carving" is genius- I need to get a router table.
They tried to give me advice, down at the record shop. I said "Sit down boys, this may come as a SHOCK. But alls I listen to, it's all freedom rock."
