Thanks for the kind words, Bootleger!
Teles come with three barrel bridges (old style) and six barrel bridges (contained in the typical Tele bridge) and some even have the string holes drilled in the back "lip" of the metal bridge assembly.
I do agree however, that some builders even use 6-saddle Strat hardtail bridges. I even own one of those as well. Probably because these simple Strat-type bridges are a little cheaper and easier to place, I've seen them now on many Asian imports. Measuring the original Fender 3-barrel bridge on a Tele and a Strat-type hard-tail bridge on another Tele, shows that the string spacing between the two outer strings (low E and high E) is 2-3/16" on both guitars.
But, my American 40th Anniversary Strat measures 2 1/16", just to confuse you all a little more. In general, I still believe that when building a guitar, you should mark the bridge holes -forget the numbers you read somewhere as specs. You want your bridge to fit right and you must space/drill holes to fit the bridge. At the moment, I am building a Tele Thinline (Semi-hollow), these guitars have two humbuckers and a Strat bridge as well. It is my opinion that a heavy original Tele bridge connects with a solid body better and conducts the string vibrations better than the much smaller Strat-type bridge. The difference is minute, unless you get a custom bridge for $100+
It doesn't seem easy for me to properly locate the original Tele bridge on the body -it's got to be exactly straight before being screwed down. In order to find that location, I string up the lower E-string and the higher E and then observe how these strings line up with the fretboard. A tiny mistake in placing the bridge, leads to the strings being too close to the edge of the fretboard! The distance to the nut is just as Bootleger states above: 25.5". You may adjust that precisely with the intonation screws later.
Hey this is fun! I'll go back my other pet project, a copy of a Gibson ES-175...
Play on!
