Guitar building help

Ok so i'm build a guitar and I was wondering how to drill the bridge and saddle correctly. It's for an epiphone SG style guitar. I noticed that the saddle is not parallel to the neck but angled a bit. How would I determine that angle before drilling the holes? As well when attacking the neck do most people just glue them on or bolt them or both or even just use screws?

Are you using a standard Tune-O-Matic and stop bar? I'd get measurements for that from another guitar if you're planning on the tilt so you don't tilt it too much. If you think about it, what you're doing with the bridge angle is determining how much range you have to adjust your intonation with, so you don't exactly have to be spot on, but you should be pretty close.

Glue on and bolt on is a personal choice, but it really depends on how you designed the neck pocket.

Ya it's a tune-o-matic. Where would I get other measurements? Or what would be a good search term for google?

How are you designing the neck and pocket? I think that's the most critical part of this all. Walk me through your process.

I ask because the measurements are going to depend on the scale length of your guitar.

so its actually a kit guitar. the scale length is 12 and 1/4 inch times 2 so like 24 and 1/2 i guess.

I fitted a tunomatic to my doublecut YESTERDAY.......

here's the archtop style piezo bridge before......



haven't got pics of the finished article, but heres the KIND of piezo tunomatic I put on (temporary setup on another guitar).......



anyway.

set the saddles to middle of the bridge.

fit the neck

the tail stop isn't TOO vital as to placement. fit it first. make sure its straight and not off to the top or bottom, though you CAN get away with a little (say a mm) withoiut it being the end of the world.

decide where you want it and mark through ONE of the holes.

drill that hole, fi the stud then fit tailstop to that one stud.

now mark where you want the other stud to be through the hole.

drill, and fit the stud, attach the tailstop.

doing it like this reduces the margin for error. if you mark both & drill then you could be out by 1mm each way... 2mm is too much!! the tailstop wont fit on the studs!

there are now two ways to mark where the bridge should go.

the mathematically correct way, and the intonation is correct way.

mathematically......

ACCURATELY measure your scale length from the neck side of the nut to the centre of the 12th fret.

measure it again to check!!

double this distance and add about 2mm for intonation changes on the low E string (the thick one).

put masking tape on the top of the guitar for marking.

do like you did for the tailstop and mark drill & fit the studs one at a time.

Intonation correct way?

I worked this out to fit acoustic bridges.......

once the tailstop is on, fit the two E strings.

put the bridge in place supporting it up on some wood shims like in the pic above.

slide it around til the intonation is right.

THAT is where you want to drill your holes.

again, one at a time!!

heres a pic of my patented (I wish!!) find the bridge temporary tailstop for acoustics



remember

Measure twice,

mark once

measure again to check

THEN drill!!

good luck!
