Bridge Location
Just about ready to start finishing the Guitar.
Last major step is to locate the bridge and mask off the location for finishing.
According to Bill Cory"s book, you measure the distance from the nut-end of the fret board to the crown of the 12th fret. The center of the bridge saddle between the D and E strings should be this same distance away from the 12th fret plus a compensation of 7/64 ( 0.11 inch ).
Is this generally accepted as correct?
Any feedback on this appreciated as I don't want to muck this up.
Also, Bill Cory secures the bridge position by drilling two 1/16 inch holes ( or possibly two 3/64 inch holes) through the bridge saddle slot into the bridge plate and then secures it with appropriate brads (wire nails) so it doesn't move. He then drills all the bridge pin holes using a 5/32 drill bit.
He then masks the area under the bridge, 1/16 inch smaller than the edge of the bridge.
So.... Is this what you would recommend?
If not, what?
Not sure it makes sense to drill all the bridge pin holes at this point or even drill holes to secure the bridge, given your only masking off the bridge location.

Re: Bridge Location
I do pretty much the same BUT I don't drill any pin holes until after the bridge has been glued on.
You will use the two small holes with nails to located the bridge again when time to glue and clamp it.

Re: Bridge Location
You just drill into not through the top this secures location perfectly.
DO NOT USE SALT this can weaken the glue I have seen this suggested in other forums

Re: Bridge Location
Salt? Slipping? Isn't that the job of those two brads at the ends of the saddle slot?

Re: Bridge Location
yes your brads and my technique with the 3/16 hole and 10-32 machine screw are much better ways to secure it for gluing.
