This is my 2nd build using this hardware (ebay $50 for bridge and head). Fender 25.5 scale with tele pickups. If interested you can look at my thread on my first build where I go over modifying the head piece in order make it easier to install and to make a larger headstock. http://www.tdpri.com/threads/a-really-fun-headless-project.915552/ The thickness is 1.5 inches. I used two ¾ inch pieces glued together for this guitar. A good source of (relatively) inexpensive lumber for a project like this is Home Depot. In my area they have a section of hardwood lumber and sell it by the foot. Mahogany, maple, cherry, alder, walnut that is exactly ¾ inch and cabinet grade. (They call in Builders Choice 1 in). On my fist headless build I used sapele. I went to my local cabinet maker and they ordered it for me through their supplier. They use sapele rather than the mahogany because the quality and workability of sapele is better. I had been using mahogany and also have noticed the problem with fuzzing…did not know that was what it was called at the time. They say that it is common in “lower quality mahogany”. What I got was 2 inches thick so some planning may be required but if you do not have a planer the cabinet shop might plane it for you (mine did for a few bucks) I like around the 1.5 inches thickness for this little guitar. The finish is Solorez filler/sealer with a Simtec top coat. Anyone interested in this application can see my thread. http://www.tdpri.com/threads/my-test-of-simtec-2k-urethane-fender’s-top-coat.704659/ I am still struggling with getting the bridge mounted at the proper height. You will notice that I had to “inset” it a bit. There is very limited height adjustment on the saddles. You will also notice the crazy location of the saddles in these pictures. I have adjusted the intonation. I am not exactly on on two strings…I am forward all the way and it seems I need to go just a tad more but the saddles are not where I expect they should be. I was not getting much change no matter where I moved the saddles. Will work more on this with a fresh mind. My first headless with the same bridge came into intonation no problem. I have to add I have seen only one of the China Headless guitars you see on ebay…Complete trash and unplayable.
