Truss rod

[Danny Seamon]

What are the consequences of using a truss rod designed for a 12 fret guitar in a 14 fret guitar? Not that I would know anybody who has done such a dumb thing. .

It was a hot rod truss rod. 12 1/4 in. Supposed to be 14 1/4. I've already glued the fingerboard on but haven't fretted it yet.

Where did you put the short end?

[Rodger Knox]

If it's adjustable from the headstock end, it's probably OK.
If it's adjusted from the soundhole, it may not work as well. The relief will be too far down the board, frets 7-10 instead of 5-8.

[Danny Seamon]

It is adjustable through the soundhole. I will remove it and put the right one in. Thanks for the help.

Got it off with a clothes iron. Used the grill cooking thermometer to set the temp to 250 F, left the iron on the fingerboard for two minutes. Worked a sharpened slightly sharpened putty knife under the end for a small distance. Repeated in small increments ...and off it came! Much easier than I had anticipated. The neck is perfect. The fingerboard has a bow now from the heat and prying. Left it in the shop with a weight on top. Don't know if it will straighten out or not. Worse case I'll have to make a new fingerboard and now I won't have to worry about the truss rod not working properly. Thanks again for all the help on this forum. Danny

Forgot to mention that I also removed the wood spline above the truss rod the same way. New truss rod on the way. The right one this time. Ha. Lesson learned...until the next "learning opportunity" ...er mistake. Ha.

Danny, don't worry about the bow in the fingerboard as it will flatten easily when you glue it back on the neck. You might clamp a beam against the fingerboard during the gluing process to keep the neck flat.
