• Tying Strings to Tuning Pegs and Bridge, Kawaiki Ukuleles - link

Bridge pins are used on some musical instruments to locate the string precisely in the horizontal plane, and in the case of harpsichords to affect the sustain of the strings.

Slotted Bridge Pins have a groove or slot cut in them which providing room for a string to pass between the pin and bridge.

Solid Bridge Pins require a notch in the bridge to for the string.

Bridge Pin Material affect the tone of the instruments and can be any material and typically wood, bone, plastic, fossilized ivory or metal.

• Bridge-Pin Science by John Mickelson - link

  What role do bridge pins play in sound? Aren't they just to keep the strings from flying off?

  Site discusses slotted vs. no slots. Bridge pin material and how it affects an instruments tone.

• Ashley's Stopper Knot, also known as the Oysterman's Stopper

  Ashley's stopper knot, also known as the Oysterman's stopper, is a knot developed by Clifford W. Ashley around 1910. It makes a well-balanced trefoil-faced stopper at the end of the rope, giving greater resistance to pulling through an opening than other common stoppers.

  • How to Tie an Ashley’s Stopper Knot

    This site has pretty clear instructions for tying this knot.

• Studding Sail Tack Bend, Buntline Hitch, Four in Hand Knot, Inside Clove Hitch

  The Studding Sail Tack Bend is security and reliability. Once set, repeated jerking and slating tend to tighten it further rather than loosening it.

• Stevedore knot

  The Stevedore knot is a stopper knot, often tied near the end of a rope. It is more bulky and less prone to jamming than the closely related figure-of-eight knot.

Action, the height of the strings above the frets, measured at the 1st and 12th frets. Action at the 1st fret is primarily affected by the depth of the slots in the nut, while action at the 12th is affected equally by the nut and the saddle.

• Lowering Action at the Bridge on Ukulele, by Frank Ford - link
• Checking Nut Action, by Frank Ford - link
• Lowering Action at the Saddle, by Frank Ford - link

• String Action Gauge, Stewart-MacDonald - link

  Measure string action (the height of the string above the fret) at any point by placing the gauge behind the string. The string height markings are at increments of .010" (ten thousandths of an inch). When the bottom of a mark aligns with the bottom of the string, that measurement is the string height at that point.

  The markings themselves are .005" thick, so referring to the top of a mark instead of the bottom adds .005" to the measurement. In this way the progressive string height scale measures in .005" increments.

Real Gut Strings

"Cat Gut" is made from the intestines of the sheep or goats. For a long time, catgut was the most common material for the strings of harps, violins, and viols, as well as other stringed musical instruments, although most musical instruments produced today use strings with cores made of other materials, generally steel or synthetic.

Nylon Strings

There are two types of Nylon strings. Extruded, and Ground. Extruded strings are made by pushing hot nylon through a small hole ground strings are furst extruded and then ground down to size.

Florocarbon Strings

Basically fishing line. A brighter sound than nylon string.

A very technical description of Florocarbon can be found on WidipediA:

Synthetic Gut Strings

Aquila has a trade name Nylgut. A synthetic material created ti have to feel and sound of traditional gut strings with out the traditional problem os gut strings.
