C-Extension Capos from Rob Anzellotti
Capo and E-Stop Installation Details:
When installing a Capo or E-Stop it is sometimes necessary to cut the threaded stud to length. All parts are made from free machining brass, and can easily be cut/ground/sanded/polished to fit a particular installation. It is also sometimes necessary to modify a Capo yoke. Example: Some extensions are too thin under the Eb to accommodate the full footprint. The yoke contains enough bulk that it can be ground substantially and still retain adequate strength.
Capo:
For a proper fit, the side of the extension should have a flat area 1 1/4" long by 1/2" (32x13mm) high, centered ± 1/4" (6mm) under the spot on the extension where the string is to be stopped. Once the proper position for the yoke is determined, drill two 3/32" (2.5mm) holes into the extension, spaced 15/16" (24mm) apart. For ebony and very dense woods, holes might need to be larger. Thread the shaft into the yoke until it looks like the right height and attach to the extension. See where it closes, and adjust as necessary. We supply gold-plated stainless steel screws which are spec'd for strength, and whose geometry allows for maximum adjustability. Use of other screws is discouraged.
The standard rotating arms fit extensions that measure up to 3/4" (19mm) from the mounting side to the string center. If you have an unusually wide extension, let us know, and we can ship longer arms.
Be aware that the threaded hole in the yoke is angled in two axes. The stud must exit the hole angled away from the string. Capos are shipped with the arms already threaded into the yokes. If you remove them for cutting, be sure to put them back the same way.
E-Stop:
Classic E-Stop shown countersunk and tang cut down.
The E-stop has a 1/2" wide x 1/8" thick (13x3mm) tang which is intended to be screwed into the neck under the nut. Holes need to be drilled and countersunk into the tang, and it may need to be cut to length. I start with the position at which the center of the arm-shaft hole is 13/16" (21mm) away from the center of the 4th string. The final working distance will vary with the installation. If your pegbox or extension is unusually wide and you think this distance will be 1" (25mm) or more, be sure to ask for a long arm.
Luthiers: The tang can also be used as a mounting point for the extension – just install a screw coming up from the bottom of the plate!
New adjustable version.
NEW — Adjustable E-Stop Arms:
The original E-Stop design received somewhat less praise than the Capos, mainly because it was more difficult to adjust. Well, there is perhaps a slight aesthetic sacrifice, but the New E-Stop arm is held in place with a small nut, and can be adjusted without taking down the setup. All E-Stops are now shipped with the "New" arm unless otherwise specified.
Nonstandard installations:
Arms are interchangeable, so you could for example have adjustable arms on your Capos, and you can also order parts separately. A few customers have chosen to use my mounts, but make their own wooden fingers. For this we can ship yokes or E-Stop plates with lengths of threaded stud instead of finished arms.
Warranty:
Uninstalled units can be returned at any time - no questions. Installed units can be returned within 3 months for any reason as long as there has been no alteration beyond shortened studs or holes drilled in the E-stop tang. (There has never been an unsuccessful installation!)
In the case of any failure that is not the obvious result of misuse/abuse, damaged parts will be replaced at no charge within 10 years of purchase.
