So by no means am I a luthier. I don't recommend this procedure for every guitar. I had a cheap bass that was unplayable and ready to be turned into firewood. If you have a guitar that's not worth the cost of fixing, this could be an option, only if you're willing to part with the guitar if something goes wrong.

| Removing the fretboard with a common iron |
I bough this old Epiphone Thunderbird
body and neck for about $15 off a scrap pile in a store here in Japan 3
years ago. After making a nut and trying to adjust everything I learned
an important lesson. Loosen up the truss rod nut first on an old rusty
neck and put some lube on it before you ever try to tighten it. While
trying to fine tun the
neck bow I snapped the truss rod. My heart sank. I got the bass up and
running, but there was always so much bow in the neck, that it was
painful to play. The strings were probably about 3/4s of and inch over
the frets. I mostly used it in a down tuning so I got away with
it for a while. Replacing the neck would be tricky as the neck pocket
was smaller than most p-basses and jazz basses.

| Junk neck with fretboard and truss rod removed |
Fast forward to this spring, I was rummaging through another free scrap
heap in a guitar store and found a cheap Chinese looking neck that
looked about the right size for my Bird. It was! However it was a 24
fret neck and the mounting position would make the scale totally wrong.
So the neck sat there for a few months bothering me. I tried
thinking of ways I could mod the neck, everything. Then not long ago I
just decided, "hell, let's rip off the fretboards on these necks and see
if I can just swap truss rods."
So, I opened up a weird chili beer I found, grabbed my clothing iron,
puddy knife and hammer and went to work. Knowing that one of these
ideas would be a mistake. But, a cheap learning experience. I slowly
worked the knife with the iron on the top frets moving up the neck;giving nudges with the
hammer as needed. It worked! Turns out this is the way pros remove fretboards.

| New Truss Rod installed |
So, I get both fretboards off and notice the cheapo free one had a nice
strong and new looking truss rod. However the receiving neck had a much
thinner rusty truss rod. I needed to route out that channel a bit
thicker for the new truss rod. No power tools. To the hardware store
and I get some hand chisels. 2 hours later with some sandpaper, I have
the new truss rod flush with the neck.
I buy 5 C-clamps at the dollar store and a few cheap stamp pads, and
glue the fretboard back with wood glue I bought in the States. Taping
off the nut end to block the glue from seeping in.

| Re-gluing the Fretboard |
Surprisingly the instructions said only 24 hours to dry was enough. I
waited a bit longer. No creaks, no cracks. Put it together. Low action. It's worked. I now have a functional truss rod. I saved a cheapo cool looking bass for
little money and a little sweat.

| Here she is! |
Total costs:
Junk Neck $0
Glue $4
C-Clamps $5
Hand Wood Tools $8
Sandpaper $3
Rubber Pads $3
Hammer and Puddy Knife $5
Already owned the iron.
So a job that could have cost well over $300 costed $28 total. Pretty good option for a guitar that wasn't worth the professional repair cost.
