Hello, i have just completed a classical guitar i have built and when i strung it up  it buzzes when i play it.  it only buzzes on the bass strings.  it buzzes mostly on the fifth string all the way up the fret board.  does this mean i need to raise the bridge?  my action at the 12th fret is between 4/32 and 5/32.  i have not leveled the frets yet because i am getting the buzzing noise not only on a few frets but on almost all the frets mostly on the fifth string.  any advice will help. thanks.

Level the frets before you go any further. You will likely need the raise the action a bit, but the first step is fret leveling.

Welcome to the OLF.  I'm a beginner too, so it would be like the blind leading the blind.  I'm sure others will chime in.  But, you might want to give some specifics.  How is you finger board tapered?  Is it tapered more on the bass side than the treble side?  Did you put a sag in the bass side?  How high above the top at the saddle?  String clearance at the first fret?  The guys that can help you need some details.

I would start with checking fret level. Then I would check the string/fret clearance of each string at the 1st and then the 12th (when freted at the 1st fret). It may be just a case of the nut slot cut too low.

Waddy asked a good question. Did you add any relief to the fret board on the bass side of the fretboard?

Do the aluminum angle levelling thing described in a recent thread; works a charm, levels the frets, nice and simple. Also, make double-sure it's not the nut (capo on first) messing with you, although it doesn't sound terribly likely.

Good idea Mattia!  Here is the thread about leveling under string tension.  Mostly applies to steel strings, but should also be good for classicals.  Maybe even better, since classical boards usually have some relief on the bass side - either more taper, sag from about the 5th to 14th fret or some combination.
