Answer 1

There are 2 types of truss rods- channeled rods and curved rods.

Channeled rods are installed in a slot just below the fingerboard. The fit must be tight and the surface of the truss rod must be flush with the face of the neck before the fingerboard is installed.

Curved rods are simply pieces of round rod with threads on one end and a "stop" at the other. A radiused slot is cut into the neck so that the center of the slot is deeper than the ends. The rod is then pushed into the slot and a curved wood piece corresponding to the radiused slot is glued into the slot over the rod. The piece is then trimmed flush to the neck and fingerboard installed. The vast majority of Gibson, Fender, and Peavey guitars use this method.

Answer 2

the truss rod is situated in a central groove or channel running along the length of the neck. a further strip of wood is often fitted to close the top of the channel before the fingerboard is added. the truss rod is usually fixed securely in the heel. because the head of the guitar is tilted back at an angle to the neck, the truss rod can be made to finish below the surface of the head and still be accessible for adjustment. as a matter of interest, the truss rod started life in classical guitars as a strip of very hard wood inserted in a groove in the neck under the fretboard and this sufficed for the low tension of gut or more recently nylon strings. the advent of steel strings led to the innovation of the metal truss rod (either adjustable or solid in the case of Martin guitars) to cope with the higher tensions of the steel strings.

Answer 3

It varies slightly according the construction of the guitar, but a truss rod is fitted in to a truss rod channel, which lies under the fretboard and is carved out of the neck during construction.

You can see a truss rod channel being carved out here:

Answer 4

I never ripped any of my guitars open to find out but i am guessing it is placed under the fretboard, because as you can see on a guitar it has the neck, then a thin piece glued on the neck for the fret board, so i am guessing its put in that way

Answer 5

you need to purchase a million/4' or 3/8" threaded rod and decrease to length. Bolts on the tip could be used to set the stress. (Use washers to unfold the strain somewhat. a minimum of one can proceed to be available.)
