Archtop Guitar Build - Finished!!!

It has taken a while but I have now turned this...
into this...
I'm very pleased with how it turned out in terms of tone, ease of play and looks.  I also took it in to get a professional opinion and our local luthier (Bill Hatfield) really liked it after he put it through the paces both acoustically and electrically.  This past weekend I played it in church for the first time and it got good reviews so now to build another one.

Here are some close-ups of a few of the details of the guitar.  First off is the finger rest and it's mounting block.  If you look closely you can see that I've cut a bevel into the side facing the strings.  This is because the neck sits low to the body (explained in an earlier post) and I needed a little more clearance between the high E string and the finger rest when finger picking. The pickup is a Kent Armstrong sidemount slimline humbucker.  I really like the sound of this pickup and the shielded wiring make it very quiet.  The single pot is for volume and I thought about a tone pot but there really is no room for it on the finger rest.  The end jack is a Fishman stereo jack that I've wired mono with the leads going through the upper roundrel of the "f-hole."


The tail piece mounts via a sarconi strap to the double ringed end jack.  The bone insert protects the edge of the top and works well.  The strings that I am currently using are nickle jazz 11's.
I hope that you've enjoyed following along with this build and be sure to check out the other cool and eclectic collection of things that I've built that are on this blog!

Archtop Guitar Build - Buffing

I had to do some touch up fills of lacquer on sink lines and small defects in the surfaces.  Once all of this had a chance to cure I once again sanded everything flat with 600 wet -> 1000 wet -> 1500 wet.  I then used my new secret weapon, the arbor buffer...

I bought this Shop Fox arbor buffer from Luthier's Mercantile (LM) and got the motor from Stew Mac (closeout priced).  The stand allows the motor to tension the arbor via a hinge mount and the buffer wheels are loaded with medium fine on the left and fine on the right.

The tech services guy from LM has done a lot of finishing so I picked his brain for about 20 minutes to find out about the do's and don'ts of buffing.  He said that you have to go down to 1500 grit before the medium fine which I thought was a little odd because the medium fine is 800-1000 grit.  I experimented by buffing with this compound after 6oo grit and he was right.  You get a very shiny surface with lots of fine swirl scratches in the background.  When I followed his directions it turned out perfect and took a fraction of the time it usually takes me when I buff with rubbing compound, polishing compound and swirl remover.

The way I prepped the wheels was by combing them with a wheel rake and then trimmed all of the loose ends.  These wheels kick up large amounts of lint when they are being combed and loaded.  If you look carefuuly at the photo, it looks like I've been shearing sheep because the floor is loaded with tufts of lint.  After the wheels were trimmed I buffed a piece of hardwood for about two minutes to get the wheels hot and then loaded them with compound.  After the compound was on the wheels I then buffed the hard wood to fine tune the wheels before tackling the guitar.

When you buff you must be sure to use only the front lower half of the wheel and be careful to not allow the top sharp edge of the guitar hit the upper portion of this sector.  If it does, It can catch the guitar and throw it out of your hands according the the LM tech services guy.  I noticed that when I was buffing around the "f-holes" that the guitar wanted to move a little so I can only imagine the rude surprise you would be in for if you caught the wrong surface with the buffer wheel...

Here is what the guitar looked like after buffing.  I took photos with both natural light and artificial light to give a good perspective.  The guitar now shines like a mirror...

*******************************

These photos were originally posted on the now defunct Dry Dock Models forum back in 2006.  I've received many e-mails and requests for the details of the building of this model so I am putting them there on this blog where I know that they will be up for all to see.

The model is based upon plans found in this book.
The book details the amazing discovery of a first century Sea of Galilee fishing boat.  These boats were common on the Sea of Galilee and because they were so mundane, there were only a few images of them in art and pottery that had survived to this date.  The discovery of this vessel gave us new insights into how these vessels were constructed and sailed.  Later in this post I'll give a very interesting example of just how this plays out.

The model was constructed using a strongback as the mold for the hull.  The mahogany planks are glued to one another using thin CA glue.   The CA glue is not visible under a clear coating so any CA glue lines that you see in theses photos will vanish under clear shellac.

Interestingly, the hulls of these first century boats were made in a similar fashion.  Instead of building a series of frames and planking them (like we would today), first century boats were built by joining the planks together and later reinforcing them with internal partial frames, just like in this model.  The only difference is that they did not have CA glue...


When the hull was completely planked, it was cut off from it's attachement to the stongback and this is what it looked like.



You can see that the hull is tear drop shaped with the bow being the more pointed end.  Next internal partial ribs were added to the boat, just like in the original.  These ribs do not extend from sheer to sheer but rather only cover a portion of the hull's profile.  A plastic spaced was used to ensure uniform spacing of the ribs.


A support for the decks and rowing seats was now installed using a wooden spacer to make sure that it was correctly spaced down from the sheer.   And MDF "mold" of the cap rail was used to shape both cap rails to exactly the correct profile and the fore and aft decks were then planked.






 These boats were steered using quarter rudders.  These "steering oars" were lashed to supports on the aft quarters of the boat.  Here are the finished quarter rudders.



The sails were then sewn up.  I used spray starch to stiffen the fabric and a pattern of seams was printed on a piece of paper.  This paper was sewn to the sail so that the seams were properly spaced and striaght.  The sewing machine perforated the paper on the seams so it was easily removed.  Next, wire was sewn into the edges of the sail so that it could be shaped to look like it was holding wind.




Lastly, I made both linen and wire rope for the model.  The wire rope is shown in its unpainted version (red) and painted version (line on the left).  This wire rope is stiff enough to keep the base of the sail off of the mast so it looks like the boat is sailing down wind.


Finally the "small stuff" was made to complete the model.  This included a stone anchor, fishing baskets, ballast bags and a net (made from a party favor bag from a wedding that my wife and I had just attended).




Here is the finished model on its stand, it was good enough to take a Gold at the Midwest Model Ships Competition.





Earlier I had mentioned how the archeological discovery of this boat had validated certain questions that we had about this vessel.  Prior to the discovery of this boat, all we knew about them came from art work on few pottery shards and a few brief mentions of them in ancient writings.

In the new testament there is a story about Jesus crossing the Sea of Galilee in one of the boats during a great storm.  This storm was so bad that it frightened the disciples, many of whom were veteran fishermen of this body of water.  The story says that Jesus was asleep in the boat with his head on a pillow.  Prior to the discovery of this boat this story seemed to not ring true for two reasons.  The first of which is "how could anyone sleep through a storm in an open boat?"  We are surprised to find that these boats were not open but had two decks which now makes it possible for someone to be shielded from the storm by being under one of them.

The second question still remains, "why a fishing boat full of scales, nets and baskets would have pillows in it?"  After all this was a working vessel, not a royal yacht.  It turns out that the ballast bags that were used for setting the trim of the boat are still commonly referred to as "pillows" to this day.  So now we can see that Jesus was asleep, shielded from the storm by the aft deck with his head resting on ballast bags!  Once again archeological evidence gives new witness to the fact that these ancient writings are valid.
