Re: Little Shocker
I'm not an electrician by any means, but I am remodeling my house and I just read a book on wiring. My amateur opinion is that you have two problems. 1) There is something wrong with the wiring in your amp. One of the wires somewhere in there has electrical contact with the chassis and that needs to...

Re: Alternatives to nitro lacquer
On further investigation, I find there are even companies making UV-emitting LEDs specifically for UV finish curing.

Re: Alternatives to nitro lacquer
There are UV fluorescent bulbs that are sold for the purposes of sterilization and for hardening of fingernail polish and cost US$10-60. I don't know if they produce the right wavelengths for the guitar lacquer, but if a cabinet from the lacquer supplier is $10,000 to $100,000, I think I would inves...

Tone complexity, "sweetness", vocabulary
I have finished my Gore-Gillet falcate-braced steel string. I'm not much of a player, but as I have carted it around to folks looking for feedback, the responses have been VERY encouraging. The issues have been: - Fit and finish: I have not yet perfected my woodworking skills to the point needed for...

Re: my first 10strings classical
Very nice work. One of your headstock inlays is similar to one I recently did, though I have to say yours is more neatly done than mine. I have yet to master neatly and accurately excavating the inlay cavity.

Re: Sitar-like open note?
Thanks, guys. I spent five minutes last night reconfiguring the nut slot and the string started sounding normal. One more fret buzz to nail and I'll be done.
Thanks for your help and advice.

Sitar-like open note?
First guitar made using The Book:
If I play the open note on the high E string, it sounds kind of like a sitar string. I don't notice this on the other strings nor it the second string is fretted to play the same note as the first string.
Anyone have an idea what might be going on?

Trevor- Wow! Thanks for the feedback! I had no idea anyone was paying attention and I had no idea I would be able to get so close! Woot!

Re: Scalloping
Perhaps an abrasive flap wheel - basically a wheel with fingers of sand paper. You would need something temporary in the fret slots to keep that part high - perhaps stiff rubber would do it - but it might give the kind of wear you would expect from many years of being played.

Another approach to the quick and dirty intonation method.
I finished up my first Gore and Gilet-style steel-string acoustic yesterday. My wife was out of town last week so I was able to work on it pretty much whenever I wasn't at my day job. I spent much of the week at the dining room table, trying to get the intonation right. I tried using the Quick and D...

Re: Quilted maple bonanza? Or am I kidding myself?
Mostly I think you are kidding yourself, but if you wanted to take a serious try, you could laminate the sides with the veneer and layers of spruce and then do a double-top style back with the maple, then nomex, then spruce. It might be crap, but it might be amazing.

Steel strings: slot the bridge? or the pins?
Does anyone have any well-reasoned prejudices for slotting the bridge or the bridge pins when executing a steel string based on The Book? From what I can see: Slot the bridge and the ball end gets hung up on the end of the pin less often. Slot the pin and you don't start out with a bridge plate that...

The font used for the detail information and the decorative flourishes both have line weights that vary significantly and do not have a drop shadow.

Re: dying ebony fretboards
Yup, leather dye will work fine. Stew-Mac sells Fiebing's black leather dye as their fingerboard stain. And, yes, I don't want to use real African ebony, either. Its ecological status is too fragile and, in addition, it expands and contracts too much to really be a good fingerboard for guitars. I am...

When I have been moved to start a cigar box guitar, I go on down to the local cigar store and offer them $3 or $5 a box. Is that not an option in Australia?

Re: Fretting about fretting
Excellent!
1) I have a second reason to buy another tool (my wife would say "YET another tool")!
2) I have a reasonable way of dealing with the glue overflow!
and
3) I have a way of avoiding glue overflow.
That's what I call a productive forum inquiry!

Fretting about fretting
The Book recommends running a thin bead of Titebond along the fret slot and then pressing or hammering the fret wire in place. I have not had much luck putting a thin bead of Titebond accurately down the slot. Sometimes I get it right, but often I get slop on my nice sanded-to-400-grit fretboard and...

Re: High angle block plane - angle? width?
Good point on the plane width.
My wooden planes are bevel down with the chip-breaker positioned about a millimeter or less behind the edge. And the plane mouth about 0.25 millimeters from the edge on the other side. Perhaps I should just be using a scraper on wood this wonky.

Well, I see I haven't exactly set off a storm of discussion.

Don't change the bracing pattern. Just make the bridge and...

I'm trying to think about how the design principles of The Book(s) can be applied 12-string guitars and baritones. The 12-string, obviously needs to be stronger to take the greater string tension. The string tension will be approximately doubled, so if the braces were 26% higher (cube root of 2 = ap...
