A bicycle, or bike, is a pedal-driven human-powered vehicle with two wheels attached to a frame, one behind the other. First introduced in 19th-century Europe, bicycles evolved quickly into their familiar, current design. Numbering over 1,000,000,000 in the world today [citation needed], bicycles provide the principal means of transportation in many regions and a popular form of recreational transport in others.
The bicycle is one of the most notable of human inventions. The basic shape and configuration of the frame, wheels, pedals, saddle and handlebars has hardly changed since the first chain-driven model was developed around 1885, although many important detail improvements have been made since, especially in recent years using modern materials and computer-aided design.
A remarkable aspect of the bicycle is its widespread adoption in many different fields of human activity, e.g. as a child's toy, in adult recreation and fitness, as a means of everyday transport, in cyclo-touring, for use in many cycle sports, and as a basis for static gymnasium or home fitness versions.
The bicycle has affected history considerably in both the cultural and industrial realms. In its early years, bicycle construction drew on pre-existing technologies; more recently, bicycle technology has contributed, in turn, to other, newer areas. Beyond recreation and transportation, bicycles have been adapted for use in many occupations, including the military, local policing, courier services, and sports. A recurrent theme in bicycling has been the tension between bicyclists and drivers of motor vehicles, each group arguing for its fair share of the world's roadways.

Try to find snap tite settings. You just place the stone flat side down and the setting "snaps" over it. Pre-notched settings also work well and tend to be a little heavier and more secure. You place the stone in the setting and then push the prongs down in an X pattern with a prong pusher or needle nose pliers. It's also pretty easy. Topako mercantile has a web site that sells the settings and has instructions how to set stones. If you buy more than $50, you get a discount. Good luck!

It depends. You can buy mountings that are pre-drilled for the stone to be seated. The ones that arent require a hand drill, like a Dremel or a Foredom Flexshaft, excellent hand eye coordination, and some experience. You have to drill the angles on the mounting to match the angles on the stone for it to seat properly and securely. The ones that are pre-drilled are easier. Just be careful when you are pushing the prongs over or you can damage the stone.

Hard stones like Dimounds, & some stones the ring is formed around the stone when it is cast. A jewler uses lighted magnifing glass & little heat from a small torch soldering tool, you can buy @ any hardware store, Gold is really soft & easy to bend, so it sound like you could just use pliers, but put some duck tape over the end, so they don't scratch. Jewlers use exspencive pliers with plastic incerts. A little vice would make thing easyer too

Turn the left stirrup around. Facing the rear of the stone, put your left foot in the stirrup. Boost yourself up, with the aid of your hand on the saddle horn. Once upright, turn, lifting the right leg up and over the gem, seating yourself squarely in the saddle. Position your right foot in the stirrup.
Mounting an English stone is similar, replacing stirrups with irons and pommel for saddle horn.
Note to "blind_wood_carver": A little vice ALWAYS makes things easier, but a little vise might be more useful, in this case.

Heating is required or else you will break the prongs.
Honestly, this is one of those things where if you want it done right, you need to have a jeweler do it for you.
