Yeah. It would certainly be much more difficult to do a multi-pulley design out of a single piece - at least with my skill level. I was able to do all of the slotting for the string path and pulleys with a table saw. I know most people consider it a crude tool, but I bet I could make a working clock with one if I had to! I chose this piece of purple heart because I knew that with a clear varnish it would exceptionally compliment the red varnish in my Geiger. It will be awhile before I can actually mount it since the bass is in the shop for another repair, but I'll post results when I can.

Here you can see varying degrees of rounding regardless of the mounting method, size or shape of the fingers. If your Capos could be smooth on the edges like these, it would make a world of difference. The other argument is the tension. You said one full turn was 1/24". Is that correct? If the threads were finer it would adjust that much finer? Correct? Well, if I go from a .105" diameter E-string to a .108" diam. string, I can turn my top screw just a fraction, not a full turn, so it feels the same. With a 1:24 ratio, it would not be possible to adjust .001-.003" as yours have a fixed amount per turn. If I go from .102" to .108" it falls in the middle again. One turn too little and 2 turns too much. I adjust my 'fingers' as the weather changes and the string slightly grooves itself into the finger pads or when I change strings to a different gauge. I think .004166" (1/24th") is a bit hit and miss to get the tension just right if you are finicky about it. Your newest extension does look nice however. |

Let us separate tension and height. On my latches, tension (rotational resistance) is "set at the factory" if you will, and is unrelated to intonation. Only finger height and to a degree angle of incidence affect where the finger stops on the string. As for adjustment, the slots in the mounting brackets allow for a lot of movement, so the Capos are plenty adjustable beyond # of screw turns. This is not the case with the E-Stop I concede, but there are ways to deal with this, and all my installers seem to make it work without incident. As for later intonation adjustments, it doesn't seem to be necessary except when changing string gauge. A dimple presses into the leather during the first days, but the leather doesn't wear or further compress after that. Perhaps it varies from bass to bass, but on my main axe I've had Capos installed for fifteen years, and I've only ever adjusted them when changing string gauge. My closure system is a significant departure from standard designs, but that doesn't mean it doesn't work Last edited by Robert Anzellotti; 08-28-2012 at 07:12 AM. |

No, I just did some very careful drilling. One hole from the back of the extension, and then another connecting that hole to the tuning shaft.

Three more Extensions..
These 3 Extensions were made by Luthier Mike Magee near Pittsburgh, Pa.
These are very well made, as are the other extensions I have gotten from Arnold Schnitzer and Jeff Bollbach. These have very good mechanics but different than both Jeff's and Arnold's work which are different to each other as well. All 3 of these Luthiers now use tunable brackets with hand made ebony fingers. |

Here's an extension I made for my Lott model bass.
The stick is Jarrah, the latches are an extremely hard local desert wood called Doolalia. Harder than ebony. I chose not to use ebony for the body or fingerboard, as I wanted the extension to look a part of the scroll, not as a chunky addition. |

Wow! That is a nice design and nice work. It looks like you brought the Long E string around the top wheel for a 180 degree turn, then on a second wheel, diverted the string to the "E string" gear. That trick is new to me.
You have a Lott bass. I recall that Henry Scott of the Philadelphia Orchestra played a Lott bass while he was in the Baltimore Symphony Orchestra prior to his tenure in the Philly. I believe his was of very dark brown varnish. Very nice job on your extension. -Dr. C. Last edited by John Cubbage; 06-09-2016 at 05:48 PM. Reason: changed to the word "prior." |
