Scalloping the guitar fretboard - possibly also renovation of the instrument
sorveltaja:
Today I sanded the the guitar body, to even out the bumps and such. There isn't much to look at it at the moment. As it will have a satin/matte top coat(s), small irregularities don't matter that much to me.
In the meantime, I also took a look if the roller nut, at it's current position, causes 'out of tune' -phenomena. Indeed it does. It's clearly audible on thinner strings, so I didn't even bother to measure it.

Again, about the body finishing. I just found out the exact kind of a patterns, that I was originally after. It's called Lichtenberg-effect. Especially, when burned in wood.
It's highly unlikely, that I would attempt to follow that road. At first, there are high voltages involved(as far, as I know). Then, the resulting smoke alone would be a prohibitive factor, if one lives in the apartment.
--
There might be slower, low-voltage methods, like using the exciter to produce tiny, hot plasma stream. In practice, it makes similar patterns(depends on the wood used), although in smaller scale.
Too much hassle, I should know by now. But still, if anything usable appears by that, I'll use it for the pickguard. Otherwise it'll have a plain colour.

Lichtenberg figure......I had to look that one up. :beer:
Sea.dog:
One or two people have managed to fry themselves playing with Lichtenberg patterning. I think it's usual to use a microwave oven transformer for the process. That's 2kV with a fair few milliamps behind it. More than enough to be lethal if you treat it with contempt :zap:
vtsteam:
Not likely to try that patterning method myself, but our 117 volt house supply can be lethal, too if treated with contempt. :zap:
Nevertheless...... :dremel:

Steve is your supply 'centre tap earthed' ?
The 110 volt equipment that I working on in various oil refineries was fed by 'centre tap earthed' supplies so there was only 55 volts to earth for each 'leg' whereas here one leg (neutral) is tied to earth either at the consumers termination box or at the local transformer, and the other leg is a nice juicy nominal 240 volts :bugeye:
