Hey guys. The neck for my first CBG is taking shape. I whipped up a jig and made the scarf joint for the head stock today. Glue is drying now. When that's done, I'll get to work on the nut then fret it. In my short time here I've seen a few fret calculators. I can find the Stew-Mac one and the Jelly Belly one. But I could have sworn there was another floating around that actually allowed you to calculate the frets and print up a full size template. I'm doubting the accuracy of the stew mac calculator. When you convert it to metric from fraction, it just changes from inches to mm without changing the measurements. For example, 20 frets, 24.5 scale length, the 11th fret is listed at 11.522 inches. If you convert the fret board to millimeters, the 11th fret is then listed as 11.522mm from the nut. No way that is correct. And even if one of them is correct, my dial calipers aren't big enough to measure 11.522 and I can't get 3 place decimal accurate with a tape measure.

This is my favorite one, doesn't need downloading. You can specify all sorts of things, or just go with the preset numbers and simply enter the scale length. You're only marking the frets anyway.

But if you do use the other settings and, it is nice to visualize the neck shape on paper first.

If you're using MS Windows you can use
wfret.com available for download in .zip format here:
wfret.zip It features a to scale printout as well.


Show us a photo of your scarf joint jig. And you might consider using a fret 0 in place of a traditional nut (essentially a nut using the same material as your frets, but slightly higher.
Diane in Chicago has more experience than I do, but what experience I have shows that they make it simpler to get the sound of the open string sound quality sounding just like your fretted string (neglecting the note/tone difference). I usually use a low diameter but widely threaded screw for a nut and then put in a fret 0. The threaded nut makes routing the string to the tuner and along the neck easier to control. Then run the fret calculator using the fret 0 to bridge measurement as your scale length. Just a tip.

Thanks Diane! That thing is complete. I'm going to have to do some research to learn what info to put in there, but it should work!


Thanks!
Wow, someone online at the same time I am. Cool.
Fretcalc. Free download, and it will output to the nearest 1/64th . Easy to convert to 32nds and do with a tape measure.
It will even run in your browser if you search with google.... w/out a download.

btw- on the Stewmac calculator .. to get a correct calculation in mm, you must enter scale in mm. I'll bet a cup of coffee you're leaving the scale in inches.

THANK YOU, 8 YEARS ON, STILL RELEVENT, JOE

Excellent. Now I have a few options. I'll take a look at them all and see what works. Matt, you are 100% correct, when I switched from inches to millimeters, I left my scale length in inches. Big old "Duh" for me.

Rand, my scarf jig is for the table saw, it is pretty much like the one in jimfrets veoh video. Except I just cobbled one together to make the one cut so I didn't make it adjustable. I set it at 15 degrees and screwed it down. Since I'm having fun with my first build, I may indeed decide to do more, in that case, I'll spend some time and make a proper jig that's adjustable. If you haven't seen the video, do a google video search for "scarf joint", it will be one of the first results.
Stewmac calculator has always worked for me in millimetres, maybe your input was wrong, I'd suggest re trying it, and as Rand suggested, the zero fret method takes a lot of the stress out of nut fabrication, good luck.

yes, me too. I always use stwemac fret calc and use mm. I also keep then info for other builds so I do not have to refigure. Another trick I learned on CBN, take yardstick and put your fret marks on that, then can use over and over. I have about 3 yardsticks like that.

For some reason, i can't edit my post, just wanted to add, re the 3 decimal places, Don't get too dismayed over that, anything inside 1/2 a millimetre, is most likely going to be better than you can mark or cut probably, [no insult intended]
Extremely proud of myself, just managed , not 1, but 2 replies to a post from December 2010, hope I helped him finish his guitar

Don't know if you helped him finish his guitar Darryl but you helped bring a smile to my face (and a bit of a chuckle).
