for those who might be interested, I'm trying my hand at more of the guitar this time.  I'm building most of the neck this time as well.  contouring the neck profile could be interesting.  I'm using walnut, maple, and figured aspen on this one with gold hardware and cream binding.  I will have more tools to buy to finish the build so that will keep it going a bit more slowly.

So the back of the body is cut to rough shape and the neck pocket is done.  Also glued the headstock on.  Got a 10 degree headstock angle on there.  I'm planning on a 24 fret PRS scale from stewmac so I'll be trying my hand at fretting as well.  I do need to find a rabbet bit set for my router so that I can cut out the binding groove around the body.

I've built up from parts/restored a few, but have neither the tools or knowledge to do it from scratch.

I actually modeled it in solidworks (3d modeling package I use at work) and that helps quite a bit in getting the tricky dimensions)

Here's the 3d rendering:

The binding rabbet bit set you're looking for is sold at stewart-macdonald.  www.stewmac.com





If you were going for a neck thru body look, why not just make it neck thru body?  It actually is easier to build in some respects,

as you don't even have to worry about making a neck joint of any kind.



My first build was a neck thru.   It remains awesome to this day, and I built it in 1987.



Neck shaping is actually pretty easy.  Have a straightedge handy so you keep the lines of the neck contours straight,

but as for the rest, shape by feel and use a single overhead incandescent bulb to generate good light and shadows,

using the shadows across the neck profile to check for bumps and dips.



A lot of people miss this detail, but the truss rod should NOT be straight when it's installed.  It needs to have some

bend in it in order for it to work efficiently.   The center of the truss rod should be 1/8 to 3/16" farther away from

the fingerboard than it is at the ends.    Seen in a cutaway, the slot gets deeper toward the middle and the rod

is held in position by the covering piece, which is clamped in under pressure and will follow the curve of the rod.



Tightening down a dead straight truss rod won't change the neck bow to any appreciable degree.  It's gotta have

some bend so it has something to push against in order to move the neck around.

That's just how I put it together in solidworks, figured I'd do a glued in neck with a deep joint.  Not really trying to go for the neck through body look, just a nice laminated board look.

thanks for the tip on the truss rod!

here are the parts with the clamps off, control pocket cut and lightening holes drilled.  also drilled a hole along the axis of the neck under the bridge for a piezo bridge wire.

nice!

I finished puting my 2 router setups together.  One is a basic router table and the other is an upright mount where the router is above the workpiece on an adjustable height slide and I move the workpiece under it.  I used that to finish up most of the neck joint and it is a nice fit, just a minimal amount of play in it, should be about right to give me what I need for aligning the neck to the body.  Now I can glue the cap on :)

I had a local machine shop create a custom set of CNC plexiglas routing templates,  for both the neck tenon and the neck mortise.


They include CNC scribed centerlines down the full length of each of them.  Since they were programmed and cut and scribed in a

single operation, I can rely on them for absolute accuracy.



I don't do the neck mortise routing until after the top is on the body, and align the centerline of the routing template to the center

seam of the top.  Anything I can do to ensure that everything is perfectly lined up is worth doing.





In your case, be really careful to ensure that your neck lines up perfectly on center with the center seam of the top.  Measure ten times,


pray after each measurement, then cut, and fit it up extremely carefully.

I believe that my neck joint is straight.  There is just enough play in it though (maybe 1/4" at the headstock) to get everything lined up.  The nice thing about the laminated body that way is that it is easy to measure up the centerline :)

glued the cap on tonight.  then I can trim that out once I take the clamps off :)

borrowed an oscillating spindle sander today so I'll have the body outline done soon :)

I cut the glue out of the neck pocket and the neck fits the joint very well.


My future build plans include a red cedar (rustic knotty) explorer with diamond plate pick guard...  I'm thinking that would be sweet and I think cedar would make a good guitar wood

borrowed the oscillating spindle sander from work and got the outline a bit more finished, cut out a notch for the neck in the top cap (it will get opened up into a pickup cavity once I get the neck finished and know my clearances)  It is a nice tight fit!

NOw if only my friend at work hadn't planed the maple pieces in the guitar body.. then the center stripe would match the neck

If you're doing it PRS style, why not do it with natural binding?  It's simpler and looks great.  Plus it's just one less chance of having a machine thrash your work to death.
Link Posted: 7/9/2012 9:33:03 PM EST
[#23]
what is natural binding?

I want to still protect the edges on the aspen top as it is a softer wood
Link Posted: 7/9/2012 10:08:46 PM EST
[#24]
Right.  Aspen top.   Interesting choice,  and definitely a softer wood.



I'm so used to seeing and using maple tops that I always expect a maple top.



My use of experimental woods (woods not typically used in guitar construction) is limited to the use of exotics for the neck,

such as Brazilian Rosewood, Indian Rosewood, Pernambuco, and Ipe.  Some of which can be hideously expensive and make

me very nervous about making a mistake that would scrap a neck.




Link Posted: 7/10/2012 9:38:51 PM EST
[#25]
yeah, that has me a tad nervous but I'll use a bit of wood hardener and aspen is similar to poplar.  I'm going to use some wood hardener on it to make sure the bridge is good and secure.  I'm curious to see how it ends up sounding with the walnut main body.
Link Posted: 7/10/2012 10:20:43 PM EST
[#26]
If I know anything about people who build guitars, it's that they never build just one.



For your next build,  if you haven't already done so,  use more commonly used traditional woods and

see how the results come out.   I'm generally partial to African mahogany if I can't get Honduran mahogany,

with a heavily flamed or quilted maple top,  and a good resonant piece of mahogany for the neck, with

an Indian rosewood or Ebony fingerboard.    They're all well known as good tonewoods.



Aspen and walnut are not really common in guitar building.   They're not as resonant  as the above named woods.





My current obsession is in finding the neck wood that has the longest, and highest pitch, tap tones possible.  I believe

that those two parameters determine sustain and evenness of note-to-note response, more than any other factors.



CJ
Link Posted: 7/10/2012 10:33:42 PM EST

I built my first guitar from a mahogany back and maple cap but with a bolt on maple neck in a LP clone.

I do really like the way it sounds and it will be interesting to see how this one compares.  there's not much on the net about aspen but Ed Roman is a big fan of walnut in his guitars.

the aspen on the walnut actually does have a nice resonance to it when I tap on it.
Link Posted: 7/10/2012 10:36:11 PM EST

I"m thinking a future build will involve a neck through design with red cedar for wings with an explorer shape and an aluminum tread plate pick guard......
Link Posted: 7/11/2012 7:28:19 AM EST
[#29]
Are you looking for flashy looks or a guitar that has tone?





If tone is what you seek, metal pickguards work against you.





I'm firmly set on my belief that the best performing solidbody electric guitars share certain specific characteristics:



1:  They are made of highly resonant woods with high natural tap tones.  The higher the better.



2:  Their bodies are symmetrical down the lengthwise axis, or nearly so.   I base this on the theory of constructive

and destructive interference of waves,  as visualized in a wave tank, which is an experiment you may have performed

or seen performed in a high school science class.     Odd, highly asymmetrically shaped bodies will cause undesirable

inteference patterns, creating nodes and nulls that move around the body as the frequency of the played note changes,

resulting in uneven note to note and string to string response.      The effect is lessened if the neck itself is made of

a wood that is resonant at a high pitch.    I specifically choose my neck blanks by the tap tone.  It has caused me

to reject a lot of beautiful mahogany because the tap tone is too low even though it's very clear and long lasting.  

To use that mahogany will result in a neck that has dead spots (wolf tones) in it.



For this reason, the Flying V is my favorite design from a performance perspective.  It's totally symmetrical and the

way it behaves when looked at as a wave tank of v shape is commendable.  The nodal and modal points stay pretty

much the same at any frequency.   Those nodes and modes don't move around much at all.   The result is that most

any note will sustain as long as any other that's close to it.    An SG is also really good due to its nearly symmetrical

body.   A single cutaway like a Les Paul is good, but a DC Standard is better.    



And, truth be told, the Explorer shape leaves much to be desired.  Looks cool, peforms badly.
3:  Use the dryest, most seasoned woods you can get.   If the wood is cool to the touch on a warm day, it's  got

too much moisture in it and needs to go into a hotter, lower humidity environment until its moisture content gets

low enough, around 6 percent or less.     Eventually any guitar maker will buy a moisture meter.

I tend to be a bit of a tinkerer ;)

the advice is much appreciated
Link Posted: 7/12/2012 7:58:30 AM EST
[#31]
Tinkering is good!   Les Paul was a tinkerer.  Llloyd Loar was a tinkerer.  Paul Reed Smith is a tinkerer.   They have all done great things to advance the

state of the art of the guitar, in their own times.



I always encourage people to try something new and different, but think it out before you commit it to wood.  



Once I had an idea that didn't pan out very well.  I "retired" that guitar with a bandsaw as there was no point in keeping it alive.  It did not represent

the quality of workmanship, design, and execution that I demand of myself.

how do you cut out those recessed areas for the knobs?


and how lightfast is that Fiebing's leather dye?

the price on that stuff is much more attractive then some of the rockler stuff
Link Posted: 7/23/2012 9:15:05 PM EST
[#39]
I made an attachment for my dremel!

I need to tweek it a bit as the threaded hole is a bit out of straight but otherwise I think it will work well.  I'll have to make a lot of shallow passes at it.  The nice thing is that if I don't have it at the right angle, it just makes a more shallow cut so that I can fix it with another pass at the right angle.







Link Posted: 7/26/2012 10:51:25 PM EST
[Last Edit: cmjohnson] [#40]
To cut the depressions around the knobs,  I spent money on custom ground milling cutters which I run in my milling machine.


I have two of them, one ground to a 3 inch radius for the volume and tone controls, and the other is ground to a 2 inch radius for


the toggle switch.     They're made from custom ground 2 inch and 1.5 inch end mills.



They're simply used as drills, stopping at the appropriate depth.  Dead simple.   But only if you have a vertical milling machine.





This is probably a method that isn't going to do you a lot of good.  You might want to try using a circle routing attachment on a router,


and set the cutter to deeper cuts near the center of the guide hole.  Use a ball nose cutter to help the transitions  stay fairly smooth


and easy to sand out.





As for the lightfastness of the Fiebing's dyes,  I'm trying to find that out, myself.  I KNOW that some dyes used by PRS (mostly  but


not always Fiebing's dyes) are proving to not last very well particularly in sunlight.  But others are very lightfast.  Problem is, I don't


know which are which yet.   The PRS color "Eriza Verde) (A very bright green) is known to be fade-prone.    Some of their blue shades


also are known to fade.





I just learned, via experiment and test, that an industrial water jet cutter is a fantastic tool for slicing a fingerboard blank off of a neck


of rare and hideously expensive exotic woods.     This allows me to get a blank, make a neck out of it, and get at least one free fingerboard


for just the cost of getting the water jet job done.     Very nice if you're working with some form of rosewood or other exotic...or even maple.





The neck for my current build is almost ready to assemble. (Fingerboard needs to be glued on...I start carving the neck after that.)  


I've also begun carving the top.   Rough carving took about 15 minutes,  now the detailed carving starts and that'll take a bit longer.

Every guitar I make is scratch built.  I always start with lumber and get VERY busy.
I even machine out my own hardware for some guitars.  I take "I built it" to the extreme.
My archtop has just one thing on it that isn't made by me, and that's the tuning machines.  100 percent




of the rest is hand made by me for that guitar.
It's immeasurably more fun to make your own from scratch (assuming you're ready to do that) than it is



to assemble a guitar from pre-made parts.
But if you aren't ready to make your own from scratch yet,  trying to build one from scratch will be at least



challenging and possibly very frustrating.   It's definitely a learned skill.





I just got done carving out the top on this one tonight.   I figure I have maybe two hours total time invested in carving the top from flat to this point.





Just a few days ago it looked like this:

I made the body from scratch on my first guitar, I'm doing a bit more from scratch on this one but not all of the wood.  I'll buy a fretboard from stewmac but the rest of the neck is to be made from scratch.

I'll use a router stand that I made which holds the router vertically with the cutter facing down to do the rough carving on both the body and some of the neck.  I'm essentially building a bunch of my jigs for this guitar build

Thanks for the tips CM!

I'm planning to do some lighter colors on the dye other then the burst.  I'm thinking dark brown wash coat then sand down, then amber stain, and then a mix of the amber and brown for the burst, maybe in a couple of stages.

Necks are easy, too.   It starts with a good quality stick.    But really it's no magic to make a neck.  You just need

patience and you must pay attention to the details.



I'm always more concerned about getting the neck mortise in the body just right.  To me, THAT is the single most

critical part and if you don't have a plan, it will be the most difficult part as well.

Yeah, I think you could do a good job building a guitar with the following tools

Router
Jig saw
Drill


Other tools make things much easier such as

joiner
plane
drill press
die grinder

Of course, simple tops keep the tool requirements down, the carved top requires a bit more of you.

I would absolutely love to have a mill and lathe in the garage but I am at least able to use the ones at work after hours and that helps.

Add a 4" class angle grinder, a few sanding/grinding discs, and a random orbital sander and you have all you need to carve

out tops, belly cuts, etc.  quickly and efficiently.   Even without the chainsaw disc that I use as stage 1 of the carving,  these

tools will work fast.

Some people like that approach,  some people don't.



I personally don't like it,  having tried it.  



I just start by scribing the line at the rim of the top where I want the carving to stop.  I then round over to near that edge

using my first carving tool,  and then once I get close to that line,  I start migrating inward toward the middle of the top,  

and down into the top toward my target thickness.    The closer I get, the finer the sanding grit I use.  



I spend a LOT of time just running my hands over the surfaces and feeling for things that aren't as I want them.



I also make extensive use of shadow lighting to reveal subtleties in the contours.   This works best when you have a

single small but bright overhead light bulb.  Turn off all other lights in the room.   Use shadows cast across the top

as a way to see the high and low spots.  It works extremely well.  



PRS uses this method.  All their top sanders have spotlights on their benches so they can use shadows to gauge the quality

of the top carve.

I did something similar on the last one.  I rough cut out with a router and then used a 4" rough sanding pad on a borrowed angle grinder.  I'd use feel to find high spots and then mark those with a pencil to bring them down.  when I got it closer to the final profile I'd use shadows like you suggest.
