I have finished installing the binding.  I’ve taken an alternative approach to this guitar.  When purfling the top with Abalam, I have, previously, installed the binding, purfling, teflon, purfling sandwich all at once.  It has been a tricky juggling process which guaranteed binding cracks, gaps, unseated purfling strips, all because I had to weave 4 different layers into the channels which were slathered with glue, then with my third hand (which I don’t have) apply the binding tape to hold it all in place.

This time, I installed the binding solo, and will clean out the glue overage, then drop the purfling, teflon, purfling sandwich into the open channel.

The photo shows the purfling strips with teflon between, and abalam in the channel after the teflon is removed.  Currently, the binding glue is drying, and a variety of cracks are being repaired under clamps.

I like this part.  The binding puts the real finishing touches on the body.  This one is more complicated due to the cutaway and the heel shape.  I’ve taken the first “easy” steps of binding the non-cutaway side.

The binding, pre-bent, and a purfling strip are glued into the channel, secured with binding tape.  I like to glue the crap out of it, which makes the cleanup more labor intensive, but these puppies need to be secure.

After the tape is removed, it almost looks like a guitar.  I will trim back the excess with a cabinet scraper before the final sanding.  The cutaway side is next, but I will need to hand bend the binding and purfling strip for the severe bend around the bout at the cutaway.

First thing this morning I took my little finger plane and smoothed the headstock down.

Since this little uke has a spanish heel, I need to route out binding channels between the top and the neck which can’t be reached by the bearing router bit.  I improvised with my dremel circle cutting jig mounted on a plate clamped to the body.

This worked well, and I proceeded to install the binding and purfling.  The bent binding came out of the bending machine almost perfect.  I only had to add a little more bend via the bending iron before proceeding.

First, the top binding and purfling was installed.  This side will also have abalam purfling, so the initial install uses teflon to create the channel to accept the abalam.

The back only has a small accent strip for the purfling.  I’ve used red to trim the binding at the sides, green for the top, and blue for the back.  Oooh, lots of different colors sure is fun.

Once the glue for the top dried, I removed the binding tape and the teflon, inserted abalam and flooded with CA glue.  Flooding will be several steps until the channel is filled and the CA glue (dried) is flush with the top.  The abalam actually rests below the surface of the top.

I’ve constructed a rosewood heel cap that will drift into the body at the back, which I will install after the CA glue dries.

This is one of my favorite parts of building:  Paua purfling.  I use abalam from the Duke of Pearl (apparently he invented abalam, which is appropriately laminated abalone).  I’ve settled on rosewood for the binding, and have prepared all the binding with red accent strips, then thinning it down to around .080″.  Four strips are sitting in the side bender overnight.  I’ll pull them out tomorrow and add more curve with the bending iron.  The channels are already cut into the body to accept the binding and purfling.  I do, however, still need to chisel out the channels where the body meets the neck.  The router bit can’t be taken too close to the neck so as to avoid putting big inappropriate divots in the neck, hence the need to chisel.

In the meantime, while the binding cures in the bender, I tackled the headstock.

Devin and I have completed the binding of the body and the fretboard.

The body was bound with ebony and BWB purfling.  Additionally a brown/white/black rope purfling was used for the top.

The back is shown with naptha towelled on, which cleans, brings out the color, and indicates where excess glue needs to be sanded off.

The fretboard has been bound with ivroid.
