C-Extension Capos from Rob Anzellotti
Capo and E-Stop Installation Details:
When installing a Capo or E-Stop it is aesthetically desirable and sometimes physically 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 rarely necessary, but installers sometimes choose to modify a Capo yolk or E-stop mount to fit the application. Example: Some extensions are too thin under the Eb to accommodate the full footprint of the yolk. The yolk 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 (but not through) the extension, spaced 15/16" (24mm) apart (For ebony, holes may need to be slightly larger). Thread the shaft into the yoke until it looks like the right height, and screw the yoke onto the extension. See where it closes, and adjust as necessary. A teflon insert is placed in the stud to provide rotational friction. If it seems that it will not sit within the yolk threads in your installation (it happens on occasion), contact us and we will send you different arms. Please use the provided lacquered stainless steel screws. They are spec'd for strength, and their geometry allows for maximum adjustability.
The standard rotating arms fit on 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 yolk is angled in two axes. The stud must exit the hole angled away from the string. If installed upside down, it may not engage the string properly. Capos are shipped with the arms already threaded into the yolks. If you remove them for cutting, be sure to put them back in the right 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 pexbox or extension is unusually wide and you think this distance will be 1" (25mm) or more, let us know, and we can ship longer arms.
NEW — Adjustable E-Stop Arms:
New adjustable version.
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 is fully adjustable. The "Classic" design is still available, and one can easily change from one to the other since the only difference is in the arm.
The new arm threads onto the stud, and is held in place with a small nut. To adjust, simply loosen the nut, rotate the arm on the stud, and retighten. No need to take down the setup.
Cost is the same as the "classic" arm. You can order either the standard version or the new adjustable arm with your E-Stop, or even with your Capos.
If you already own an E-Stop with the "classic" arm and would like to trade it for an adjustable, I will do the exchange for a small handling fee, and please return your old arm after you have made the switch!
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.
