guitar build session 9

Missed another week but last wednesday I was back in the workshop with Martin my luthier/tutor. More neck work. A slight radius was sanded on the fretboard surface. Next, the frets. Starting at the body end of the neck I cut pieces of fretwire allowing a couple of mm overhang. The pre-slotted slots were gently cleaned of sawdust with a fine saw blade. The fretwire was gentyl presses into the slot. Using a small hammer head as a sort of punch, with masking tape to cushion it, using a mallet, the frets were tapped into place starting at one end and working across the face to the other end then the surplus snipped off. The ends of the frets are prevented from springing up with a drop of superglue on the them which sort of gets sucked into the slot. The hammer head was used to apply pressure for about 30 seconds until the glue had set. When all fitted, a file was used to smooth the ends flush with the neck edge. Then running the file lengthways at an angle, a bevel was put on them. The rest of the session was used to further shape the back of the headstock. Photos to come later.

guitar build session 7

I'm a week behind posting this and this week I will not be doing any work on it. So last week was all about the neck again. The fretboard had been glued on so now needed trimming back to the neck profile using the router table and a small cutter with wheel guide following the shape of the neck. The body end of the neck cut to the correct length and shaped to fit the body "pocket". So now I could put it in place and see how the guitar is shaping up as a whole.





















I spent the rest of the session roughing out the back of the neck. We drew lines down it at specific points as a guides to cut back to. Just using a spokeshave and a coarse rasp, I reduced the back of the neck to a sort of triangular profile. The ridge of that was taken off leaving a sort of flat topped triangular shape, then those two ridges taken down so we now have an approximate D shaped profile. I ended the session there. Doesn't sound much but it was four hours of hard graft. I reckon we might be about half way through the project now.

guitar build session 5

Had my 5th session yesterday. Feeling very tired this week after many hours of sanding down walls and woodwork in my lounge ready for redecorating, plus running around hospital visiting. So it was a welcome return to sanity but at the same time, I couldn't put 100% into the sawing and sanding that was involved. This week involved fixing small templates to the body to route out neck pocket and a cavity for the lipstick neck-position pickup. I'm starting to gain confidence in the use of the router, always had a slight fear of them based on my lack of experience. The key to it is to only take small 2-3mm cuts each time.








Next we started on the neck. I'd bought a hefty plank of maple. We drew on the approximate shape and as the plank is thick enough, decided to make it a one-piece neck/angled headstock. So we marked on the angle of the headstock and rough planed the bevel that will be the top of it. The idea is to cut away most of the surplus wood first with a jigsaw, then make the final shape with router and spokeshave. Attempting to rip down the length of the neck proved a bit of a disaster. I broke two jigsaw blades and was just getting nowhere. Maple is a very hard wood! I suggested we end the session early and I would take the plank back to my workshop to rip down on my bandsaw. We did a few other small jobs - cutting the pre-slotted fretboard to length and marking a few things up to round off. Progress a bit slow but still satisfying. It's hard to see the light at the end of the tunnel yet as there is a lot to do but I rest assured and imagine the day when I will take the finished guitar home, plug it into my new vox valve amp and enter the kingdom!

guitar build session 3 and 4

So I need to catch up on my posting for the reso guitar build. Session 3 we fixed the template to the body with a couple of panel pins in places where the hole won't show. Using the router, I followed the contour of the template, taking about 2 mm off on each pass until eventually I had almost cut through the block. We then turned it over and using a router bit with a wheel guide running along the new shaped edge, I cut through the remaining bit and seperated the new body shape from the block. At last it's starting to look like a guitar. Next job was to cut a hole in the template where the cone is gonna sit. I took the body home to do some homework on it over the Christmas perion. Basically just rough drilled the main part of the cone well out using my drill press, to save effort on the router.

Session 4 - we attached the template again and now following the hole we had cut in it, slowly routed out the well for the cone. We also rough sanded the front and back to get a flat surface across the whole body. We then used a small concave router bit on the outside edges to produce a gentle rounded prifile. I took it home again and spent about an hour sanding down the outer edge and front and back nice and smooth. Next session we start on the neck.

guitar building course session two

Second session of my course where I am building a solid body six string reso guitar. Didn't realise how much preparation work needs to be done before actually working on the guitar itself. This week we cut the mahogany plank in two. We sat the two halves side by side with a small gap and using a slotted template on top we routed the two edges simultaneously to provide smooth faces to be glued. Quicker and easier that trying to plane them. They were glues up and cramped together to make the block of wood for the body.

Next job, made a template for body and headstock by tracing the drawing onto some thin MDF. We cut them out with a jigsaw, then smoothed the edges to a perfect shape with rasps and sandpaper. These will be fixed to the body block and headstock piece and used to run a router around to cut out the shapes. It took us pretty much the whole session to do these jobs. Another session next week then a break over Christmas. What I've learned so far - the need to make a good drawing and templates. The simple use of a router to provide straight edges accurately and easily. I'll be digging my own out now I know what can be done with it.

guitar building course day one

I mentioned in my last post that I was going start on a guitar building course to build a 6 string reso cone, solid electric guitar. OK I know this blog is supposed to be about CBGs but there are many of you who are also interested in more conventional guitars too and learning some general building tips. The idea is that I learn some new skills and build myself something really special. It's loosely based on a National resolectric but with some of my own tweaks to it. I've done a rough photoshop job to show you what it might look like.


I will be building it in half day sessions, roughly once a week. So the first day we headed off to John Boddy's timber yard near Boroughbridge. There's a big warehouse with lots of planks of interesting timber. Martin, my tutor helped me select a piece of maple for the neck/headstock and mahogany for the body. Mahogany was chosen because it is a fairly light hardwood which should emphasise the bass end of the tonal range to balance the rather toppy reso cone. I also bought myself another maple plank that will cut down into 4 nice CBG necks for future builds. Was surprised how relatively cheap maple is. The neck plank cost about £8 and the CBG plank about a fiver. Back at Martin's we started to draw up a full size plan of the guitar. Didn't quite finish it this week. We ordered some hardware too - truss rod, reso cone and plate and a pre-cut rosewood fretboard. Next session we finish the drawing, cut the mahogany in two and glue both halves together to make a wide plank for the body. Probably start cutting out the neck too.
