Covering my assets

Those are some big clamps

This picture may be deceiving.  I am not, in fact, gluing up another body blank.  The above photo is documenting the first stage of making a veneer for the headstock overlay.  I did this once before on a lapsteel guitar that I built.  But in that case I was using store-bought paper thin veneer and it was to cover up a rather glaring mistake.  This time I'm making it from scratch and it is to tie the neck and the body together in an aesthetic way.  The above laminations are some of the scraps left over from gluing the body blank together.   The two outer pieces are Lacewood, the middle pieces are Basswood and center piece is Purpleheart.  Instead of using the extra mahogany I had left over I just turned the Lacewood on its side - to really show off the laces - as I felt this was missing from the body blank.  I glued and clamped just like with the body blank and was left with this:

Hey, look at that...
A chunk of wood!
Since this was going to need a lot of work - I didn't sand or scrape it much at this point.  I did scrape away any excess dried glue (aka squeeze-out) on the face - but only enough so that this would be flat - not finished.
All your fetishes, nightmares, and guitar plans can be found on the interwebs.
As I am building a Les Paul style guitar - I wanted a Les Paul style headstock.  The Epiphone that I have been using to model/measure doesn't have the traditional Les Paul headstock - so I went digging (or is it trolling - I can never remember) on the internet.  The above image is what I found.  I don't love the above image.  It's close to the shape I had in mind but it's not exact.  The very top of the headstock looks like an open book (or a mustache).  This version is a bit too voluptuous for my taste. I think it should be a bit more subdued.  So, I'll probably modify this.

Anywho!  Depending on which headstock you are creating an homage to, you would: find the image, print it out and then take an exacto blade to it.  And you are left with:

No trademark infringement is intended or implied
One other issue that is a bit of a problem for me is that the headstock on the neck I am modifying isn't the same length or width as the above template.  So, I will need to nip and tuck a bit - on both the existing headstock and the template.  That may cause havoc with the tuning peg holes (the six circles in the above picture).  But we'll burn that bridge when we get to it...

You know the drill...
You trace!

It's the same as about...
You cut with a jig saw!

50% of the posts on here...
You sand!
It's all a bit repetitive, no?

Ah!  Here's something new and dangerous...

You are left with a big frickin block of wood.  How the heck are you going to add this to the headstock?  It'll be two inches thick...?  

Now is the time that you make yourself a veneer (aka a really thin piece of wood).  The best way to do this in a home shop is with a band saw.  Sadly, I don't have one.  And I wasn't wild about the idea of using the jig saw for this.  A jig saw would just make a mess of it.

You could try using a table saw and running the piece through once then flipping it over and running it through again.  But how do you hold such a small piece of wood with a spinning blade of death so close to your fingers?  (No, seriously, if any wood workers want to share that bit of wisdom - I'm open!).  The safest way (and the most time consuming by far) is to use a hand saw in a miter box.  

...so, of course I didn't do it that way either...

I covered the whole thing in double-sided tape, stuck it to the end of a 4 by 4 piece of stock, and ran it through the chop saw.

Kind of like this...
Lessons learned?  
Well... It worked!  
And the saw didn't kick the wood out and hit me in the teeth.  So, I'm kind of happy about that.  

In truth - even after it went through the saw - the workpiece was still pretty stuck to the 4 by 4.  So, it was fairly safe.  I didn't take pictures of this because I was concerned that someone would try it and lose an eyeball (wear your eye protection, you whippersnappers!) but I thought I should come clean - as a big part of this blog is to share my experiences - not just the outcomes.  

Having said that - just as a way to cover my own, ahem, assets - please test the adhesion before you try this.  I made sure that the workpiece and the 4 by 4 were strongly adhered to each other.  I kept my body and face away from the most likely kick-out path of the workpiece.  And I wore enough protection that most of my face was covered (eyes, ears, and nose/mouth).

Another thing that I didn't photograph (but should share) is that I had to do this a second time because the above veneer was too thick.  The second one was about two thirds as thick as the above veneer - and that's the one you see in the photos below.  I used the same process and had the same results.  
I'm always open to safer methods - so please feel free to comment if you have an opinion.

I mustache you...
Do you know how to use that thing?
After the veneer was cut to thickness - it needed to be reshaped to fit the headstock of the neck I'm using.  I used a coping saw to cut the rough shape of the top and also remove a bit from the bottom (where it meets the neck/nut) with the chop saw.  It's hard to see in the below picture but the existing headstock is asymmetrical - so that's why it had to be shorter - as the new headstock shape is symmetrical.


Pictured: Fiddly Routing
Once the headstock veneer was close enough to the shape that I want (yet still fit on the existing headstock) it was time to bust out the router.  Now, with such a thin template (the actual veneer) and the intricacy of the shape - this was some finicky (nay fiddly) routing.  I tried using the double-sided tape to adhere the veneer and the existing headstock - and it worked like a champ.  So, I didn't need to break out any clamps for this job - which made it easier.  Be careful though - if you don't use enough tape - the router will turn that veneer into a missile
.
That's when it goes from fiddling about to flinging about

As you can see - there is some clean up work to be done.  Much of it can be done with the belt sander. Some needs to be done with a coping saw, micro files, and a very sharp chisel.  

How sharp?
Very.
When we get to the part where I glue the veneer to the headstock I'll tackle this properly.  
There's still loads to do (tuning key holes, final shaping, binding, etc.).
Until then here is a preview of things to come.

I do not think that word means what you think it means...

I know what you're thinking...


"What kind of a flim-flam-scam are you running here? That's not a Tele!"
This is true.  The shape drawn on that body blank is not a Telecaster shape.  It is an altogether different animal.  It is, in fact, not even in the correct Genus (Fender).  That is a Gibson Les Paul body shape.

I have turned this blog into a Den of Lies!
Come along with me - let's have some fun...


For those of you coming here for the first time - the original Telecaster build can be found 'below.'
By that I mean - see the older posts from 2008.  For those of you who have not closed your browser window - let's see what's going on here.

First, why am I building a Les Paul?  The easy answer is, "Why not?"  The slightly longer answer is that it is more challenging to build a Les Paul than it is a Tele because of the carved top.  It's also usually harder to build a guitar with a 'set' (e.g. glued-in) neck.  ...but I'm not doing that.
I'm building this with a bolt-on neck (as I'll explain in a later post).

So, because it's not a real Les Paul - I don't have to worry about copyright (or is it trademark) infringement then - now do I?  Fingers crossed!

There's one guy in the peanut gallery shouting, "Why don't you just carve the Telecaster top?"  
I'm ignoring him.  La la la la la la - I can't hear you!  

Enough with the 'why' let's move onto the 'how.'

I own an Epiphone Les Paul - so I used that to trace the shape onto the body blank.  In this post I'm just going over the first pass of creating the body outline.  There are two steps when doing this with regular tools.  I say 'regular' because the major guitar manufacturers have specialized tools that do this process in a few minutes unlike the below process which is measured in hours.

The first pass it to remove 90-95% of the excess wood.  You can do that with a band saw, jig saw, or even a hand saw if you have that kind of time (I do not).  The idea is to get close enough to the final shape that you can easily finish it (smooth it out) on the second pass with a router.

I'm using an inexpensive jig saw to remove all the excess wood.  The process for a band saw is different (but as I don't have a band saw I'm not qualified to tell you how).


My process (stolen from somewhere online) is to make multiple cut-ins so that I'm making a series of small cuts.  See the above picture for what I mean.  I then cut along the trace-line with the jig saw - going from cut-in to cut in.  It makes the process slower but much more accurate.

For the first build I did (the Tele) I just went around the whole body in one go - right up against my traced line.  Let me tell you why that was a bad idea...

It's called flex.  And jig saw blades have it in spades.  If you try to make sharp turns, corners or switchbacks with a jig saw - you end up with ridiculously sloppy cuts because the jig saw blade bends as you cut.  It's very difficult to keep it straight (or square).  On the Tele I was very close to the line on the surface of my cut - but the back (or bottom surface) was 1/4 of an inch bigger or smaller.  Because of that I had to modify the body shape a lot with the router.  So now I do it this way.


What you see there (above) is not the top of the line tool for this job.  It doesn't need to be.  Take it slow and it'll be just fine.  You may be able to see that I didn't go right up to my trace line with the jig saw cuts.  That's because I'm not going to go that close to the line on this first pass.  My goal is to get about 1/4 of an inch from the line and use the router to clean it up.  It would probably be better if I got within an 1/8th of an inch - but I have a better router than jig saw - so that's how roll.



Well, what do you know.  I think there's a guitar in there after all.

Image is everything

The lamination sat in the clamps for about 48 hours.  I then brought everything back to the workshop - took off all the clamps - and was left with...



...at this point you may be questioning my taste.
Looks pretty ugly, huh?
Hold that thought...



There.  That's better!
So, what just happened?

After removing the clamps, I took a small surface plane to the thinner laminations (the lacewood, basswood, and purpleheart) because they were about an 1/8th to 1/4 of an inch proud of the mahogany.  Once all of the pieces in the lamination were roughly the same height I busted out the sander and some 60/80 grit sandpapers.  It's dusty work (and not really necessary at this point as we'll see) but it's hard to argue with the results.


Results.


Results.

Full disclosure - I also changed the lighting a bit and wiped the piece down with mineral spirits.  That's the real reason the grain is popping so much.  The mineral spirits gives you a preview of what the wood will look like once a finish has been applied.  The nice thing about using mineral spirits is that it evaporates quickly and doesn't raise the wood grain like water.

In the close-up images above you can really see the figure of the Mahogany and the 'laces' of the Lacewood.  

The truth is though - that everything after taking the piece out of the clamps and planing the lamination flush was a waste of time.  I am going to be carving the top of this guitar.
See the image below for what I mean.  See how there is a sculpted aspect to the shape of the top.  That's a carved top - and they are purdy.


This particular image comes from http://williamsguitars.co.uk

I'm not ready to carve this top yet - so sanding it was not really necessary.  I did it more for inspiration than anything else.  Hence the title of the post.  Image is everything.  Seeing what this is going to look like when it's completed is a motivating factor for me.  I want to see that final finish. That's why I've done this on each of the guitars I've worked on to this point.  Psyching yourself up can be the difference between the woodshed and the couch.  At least that's what I tell myself...

Back to business!

When I planed down the laminations I created a few-tear outs.  Mostly because I've never tried using a hand plane to smooth a surface.  Previously I've used card scrapers, rasps, and sandpaper.  But sanding 1/4 of an inch just takes forever - so I figured I'd try using the hand plane.  Once you get the blasted thing sharp enough and set up properly (and you are using it correctly!) - it's wonderful to use.

You can see one tear-out in the Mahogany in the below picture.  It's the little black spot just above the laminations on the right.  At some point I'm going to need to sand, scrape or fill that hole.  



It was caused because I was planing against the grain of the Mahogany.  I was planing with the grain of the lacewood - but when I glued the Mahogany to the lacewood - I glued them with opposing wood grains.  Would an experienced woodworker have done that?  Probably not.  But also remember that plywood is stronger than regular wood because the laminations have opposing grains.  So, what I'm saying is: Could be good.  Could be bad.  Time will tell.

I was concerned that there might be gaps in the laminations - either because I didn't prep them well enough (read made them square) or because I didn't squeeze them hard enough when clamping them.

I seem to have done okay.  There are a couple of gaps but if I play my cards right - they will be scrap wood on the floor once I cut the body shape out of this blank.  Again, time will tell.

In short - I'm happy and ready to move forward with this build.

So, now that I've freed up all of those clamps I guess it's time to look at that other body blank...



Hmmm...


Round 2: Fight!
