Neck set - bridge height question
When setting a neck, what is the best way to determine the bridge height? According to the Treager book, on page 132, bottom left hand column, he puts a straight edge on the fingerboard, makes a mark on the bridge, then adds 5/8" of an inch for the finished bridge height. Does this sound reasonable?

I put a straight edge on the finger board and made a mark on an old bridge at the highest point, this read 6 1/4".
6 1/4" + 5/8" = 6 7/8" bridge ht? Here is a photo to help explain the procedure: Thanks in advance. |

The addition is more like 10-11mm, or 3/8", if you are going after an average modern steel string set-up.

So my straight edge on the fb should hit around the 6 1/2" point of the bridge to get a 6 7/8" (175 mm) bridge height?
Also, is 175 mm a good bridge height? The bass is a Panormo copy, 170 mm spacing between the upper f-hole eyes. |

but..
Are you putting bridge adjusters in the bass? If so, take that measurement in consideration or you will have to re-cut the top of the bridge after the adjusters are in a second time. Measure twice, cut once.. Then again.. measure 10x.. twice may not be enough..
Are you really using that bridge in the picture with the funny looking foot joint? |

I am in the process of cutting the neck angle and fitting the neck into to the mortise. The finger board in the photo is being held in place with a mock neck. This is to help me figure out all the critical dimensions like over stand, neck angle and bridge ht. Believe me, I'll be measuring more than twice. |

That's a little high, especially if the top arch is high. If so, you are putting the bow arm far from the player's body and inviting shoulder stress. I think 6 1/2" to 6 3/4" is good for a 7/8 bass, unless the c-bouts are really wide.

Big basses and those with higher/deep shoulders (or combined) need extra special attention to detail over the normal 3/4 or 7/8th basses because if you can't play it, what good is it. The true Panormo's and basses of that School are ofter the larger 7/8ths to 4/4 in size by today's standards. Playability in its measurements in my mind are equally important to any other detail of the bass. Arnold, since my Bass is done already maybe you can critique it from the #s and pics listed to possibly guide others as far as what's best and what's not. Some time sonner than later you will see this 'big boy' in person and have a better birdseye type view of it but for now I am sure you can say a few things on the subject that might benefit us all. |

Hi Craig, Here is a sober opinion.
Since you are building the bass, start with the ideal numbers for bridge height and overstand. |

Use a neck template to find the neck angle.

Ken?
30mm overstand? Is that what you have there? Quite low in my book. Most builders today use from 35-40mm. Decreases the angle of the Neck to the player and helps with the Top tension as well. Keeps the hands closer to the body when playing with less angle pitch I would think.

It moves in and out for overstand ht. and pivots for the neck angle. The screw in the neck block isn't very cool but I was very careful. |

Came up with 1 1/2" Overstand, could be high but the bass is huge.
Ken, your bass is looking great! |

humm..
Cherry Back and Ribs? Classy looking fellow..
Minimum I think is 35mm and 40mm maximum for the overstand. Bigger shoulders might need 36-38mm as opposed to 30-35mm. Bridge height should be 6.5-6.75" at the center with lowish string height. This is my personal preference. |

Fun Fact: Cherry is part of the Rose family, Prunus Serotina Rosaceae.
