[LUTE] Re: See through soundboard?

 Dear Herbert,
 There is an extraordinary photo of Chris Wilson on the back of the booklet

As I recall that was a Naxos CD, I have it somewhere.

My understanding is that is was a standard photographers flood light
backlighting the whole scene.  Cant hurt to try it, provided you minimize
the time the lute is exposed to the intense infra-red heat source.  Might
be those new-fangled light bulbs would work as well with much less heat.

   Herbert,



   You are better off soldering one of those very bright LED's (or
   several) to a stiff set of wires. Both the wires and LED fit through
   the rosette and can be positioned right next to the braces near the
   soundboard. I make a template out of sheet aluminum with a hole smaller
   than the selected rosette hole, so the rosette is not touched during
   this procedure. The template is taped to the top. In a dark room, this
   method can spot loose braces and can measure both the thickness and
   height of a brace, by it's shadow. With the LED, you don't run the risk
   of burning the top, or electrocution.



   They are getting those little USB cameras smaller and smaller. Soon
   maybe you could put a USB camera through a rosette hole.

Dear Herbert,
There is an extraordinary photo of Chris Wilson on the back of the booklet
of his 'Fantasia de mon triste' CD showing his lute with a strong backlight
where you can see that effect. In that particular case the light is clearly
shining through the back of the lute and still illuminating the inside of
the soundboard. However, it won't work with every lute as only some of the
woods used for ribs are that translucent

Best wishes,

Denys

If I arranged a 120 watt light at the rosette, and
and shielded it so the rest of the room was as
dark as possible, would I be able to see 
silhouetted braces through the wood of the
soundboard?

Dear Stephen,
How nice to hear from you! It's great to know how that effect worked.
Thinking about this subject put me in mind of the recent photos
on your website showing light shining through a lute back, but
even those don't show quite the intensity that's apparent in that
photo. So it's not an effect many of us will be able to replicate...
Hope you are both keeping well  busy!

Best wishes,

Denys

Hi Denys,
that lute is made of ivory, which is why the effect works . . . I  
replaced its soundboard, back in 1983, I think.
