Louis Gaspar Uke Dissection – Part 2

August 1, 2007

 

I looked a little further into my Louis Gaspar ukulele. I measured the heck out of it, and ended up doing some serious head-scratching.

Who was Louis A. Gaspar?

I think that the overall design of this uke is fantastic. After measuring the instrument, it makes a heck of a lot more sense than the blueprints I have for a Martin and Bruno ukes. Everything is laid out logically on the Gaspar. The design seems to take final product and construction into consideration. This is a real uke, it wasn’t designed as a mini-guitar.

Everything would be make more sense if the uke wasn’t so crudely built.

The odd neck shape started to make sense when I measured it. The neck is straight along one edge. The bass side of the fretboard…the “fleas” side (my dog has fleas tuning) of the fretboard is straight. The other side of the fretboard (the “my” side) is angled. The frets are roughly perpendicular to the “fleas” side of the neck. When you measure the frets against the top edge of the neck they are at an angle.  The wonky-looking frets are mostly an optical illusion, because all the taper of the fretboard is on one side. Both sides of a traditional fretboard are slightly angled.  

I had a bit of an “AHA!!” moment at this point. This design makes sense in so many ways. If you have one straight edge, construction is much simpler. You can use the tablesaw to run the fret grooves and the nut groove w/o making any jigs or having to trim the edges later. Always a straight edge present to refer to if you need a line.

Brilliant idea right? Yeah. Well forget it…even by that logic, this Gaspar neck is still bunged up. The frets are a degree or more out of true no matter which way you measure them.

Next stop: The heel.

 

The heel was cut from a 1  3/4″ cube  glued onto the bottom of the neck blank. The heel shape was probably roughly formed at this point (taper of heel cut, rounded heel cut-out made). Then a 1/2″ section of the end of the neck and block was sawn off to use as a heel block inside the body.

 

This is another great idea. I have had lots of trouble making heel-blocks match the inside curve of the body and then somehow getting a neck to match the whole package and stay straight, is very difficult. It seems like this method of sawing the end of the neck and heel off to make the heel block is at least one less step work and might even be easier to align. 

The back of the neck is more or less flat, rather than radiussed. The sharp corners were knocked off the blank a bit, but not much finishing lavished on the back of the fretboard.  

Flipping the uke over, the back of the heel tells the whole story of the slightly off kilter look of the body. The sides were overlapped at neck (!!). I get the feeling that the whole area was probably slobbered with glue and jammed between clamps – just sort things out on the belt-sander later I guess.

 

This is one of the big head scratchers. On one hand, its a pretty cheesy joint. But that cheesy joint is still very strong. Actually the neck joint is about the only joint in the uke that is still intact after all these years. So depending on your sense of humor, this method is either a lazy shortcut or another construction/design innovation on Gaspars part. I’m still on the fence.

The flat wood on the Gaspar uke is all very thin. The top and back are nearly dead on 1/16″ thick. The sides seem to be thinner, but I think they are thinned a bit on the visible edges when the uke was finish sanded. Thicker toward the center, but I don’t have a micrometer which can get past the clunky binding.

The side-wood actually looks thicker inside the neck joint – so I’d bet that the sides are 1/16″ in thickness like the top and back are.

The back has a slight arch across the waist, a little more than 1/16″ but not really 1/8″. Its Hard to see behind the square in the picture.

After all the measuring and obsessing. I really have come to admire this ukulele.  I love the overall Gaspar look. The angle along the top of the neck combined with the 4-in-line tuners give the uke a jaunty modern look. It’s one fast looking uke – looks like it is flying, even when its standing still. Some of the construction details are pretty amazing. Gaspar may have not been a very good craftsman, but he certainly was good at designing ukuleles. A savant of sorts?

I’ll be reassembling the uke soon.

    Excuse my request, but do you share the measurements of this Gaspar ukulele?
