(A dioptre, or diopter, is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres (that is, 1/metres). It is thus a unit of reciprocal length. For example, a 3-dioptre lens brings parallel rays of light to focus at 1/3 metre. The same unit is also sometimes used for other reciprocals of distance, particularly radii of curvature and the vergence of optical beams. The term was proposed by French ophthalmologist Felix Monoyer in 1872.

One benefit of quantifying a lens in terms of its optical power rather than its focal length is that when relatively thin lenses are placed close together their powers approximately add. Thus a thin 2-dioptre lens placed close to a thin 0.5-dioptre lens yields almost the same focal length as a 2.5-dioptre lens would have.)

SAWFRAME SWISS 2 3 4 DEEP ADJUSTABLE STYLE

Revolutionary design in three lightweight, perfectly balanced sawframes. Ergonomic handles reduce fatigue and provide greater dexterity. Patented blade-lock design eases blade insertion, maintains perfect alignment and eliminates wobble which reduces blade loss during use. * Precision-made at our Swiss factory of the highest quality spring steel with non-glare finish. Set screws can be used on either the left or right side of the frame according to your preference. 2-3/4″ (70 mm) deep. * Blade tightening screw must be opened wide enough to allow sawblades to be inserted all the way.

Tips for Choosing a Jewelry Saw or Piercing Saw:

Adjustable or Fixed frame? Will you only work with full sized frame blades (pegged or unpegged) or do you prefer a saw (always unpegged) which can accept any length of saw blades, including longer bits from blades you have broken during work? Adjustable saws can be adjusted to a shorter frame to hold broken bits of blade.

Hand Grip Some newer models have soft, easily gripped handles. As blade control is related to grip, you may want a larger, softer handle if you suffer from arthritis or have a weak grip.

What Size Is Your Material? Jewellers saws are held straight up and down to saw. The size of material you can cut, will be determined by the throat depth of your saw. Smaller saws will only be able to cut into the center of a piece of wood which has a radius (measurement to the center) less than the depth of the saw frame’s throat. A saw with a three inch throat can only cut into the center of a piece of wood which is six inches across, or can cut completely across a piece of wood which is three inches across.

Method of Tensioning the Blade Non adjustable frames must be tensioned by pushing the head of the saw frame into a piece of scrap wood or the edge of a work surface, while you press down on the handle to temporarily narrow the gap for the blade. Adjustable frames can be tensioned after the blade is attached to the frame, by pressing down on the stop at the bottom of the adjustable frame. There is no particular advantage to either system, although the tensioning adjustment via the adjustable frame is sometimes easier to set more precisely.

TUNGSTEN SOLDER PICK WITH HANDLE

Wood handle with sharp pointed tip for placing, holding and positioning solder in just the right place. For platinum soldering with tungsten tip.

Used for positioning solder while soldering.  Tungsten tip is for platinum, as it can withstand the higher temperatures required for such work, and it won’t contaminate platinum like other solder picks will.

It does not appear to be generally known that it is not difficult to solder metals to tungsten; Angerer states that Neusilber (German silver) can be used, but with this exception the general opinion seems to be that welding is the only practical method. In fact, there are a number of metals that will run on tungsten, of which gold, palladium, zinc, and (I believe) nickel are the most important.

The ability to be able to Braze is an asset worth investing in.  Silver Solder is a Hard Solder Method and is used for Soldering Tungsten Carbide Tips to Tool Holders and Tungsten Carbide Tips on TCT Saw Blades etc.

Torch Heads are available in various forms from top of the range instant piezo-electric ignition down to a basic pencil flame torch, the one shown in the picture is a middle of the range swivel head torch.

Most Torches can be used with either Propane or MAPP Gas, I prefer the MAPP Gas as this gives a higher heat [150/200°C Higher] and therefore increases your Brazing Capabilities.

MAPP Gas although slightly more expensive it is well worth the extra cost.

Silver Solder is available in numerous grades I use a general purpose Cadmium Free version with a high Silver content of 35% [typically AG35] which has melting temperature of 680/700°C.

The only other requirement is a suitable Flux, in either Powder Form or Pr-Mixed although this has a limited shelf life, you can also purchase pre-fluxed Silver Solder which can be more convenient.

SOLDERING TORCH PREST O PAK SILVERSMITH WITH 1 TIP

Permits mixing of acetylene with air at the torch head, so no other source of air is necessary. The acetylene is stored in tanks as a liquid and only becomes a gas when valve is opened. The silversmith outfit (No. 14.236) includes: torch handle, 1 light flame tip, regulator for “B” tank, and a 6′ (183 cm) hose with fittings. Uses “B” tank. Shipping weight 5 lb. (2.3 kg).

If you are unable to put the solder under the piece at the seam, you will need to use your solder pick to move the solder in place after you have heated up your piece.

Trouble shooting. If solder does not flow, it usually results from one of three problems. 1) Check to be sure the seam fits flush. 2) Check to be sure the seam is very, very clean. This is especially important if you tired to solder and the solder did not flow; often the solder is not flowing because the seam is oxidized. 3) Be sure your heat the entire piece evenly before you concentrate your heat to make the solder flow at the seam.

Always work with proper ventilation.

Be sure to work on a fire safe, metal surface.

Be sure to have a fire extinguisher handy when working with a torch.

Use gloves when working with chemicals.

Always neutralize acid pickle with baking soda before disposing.

Household items used for jewelry making should never be returned to household use after being exposed to chemicals.

Ever been caught in an emergency and needed to get a ring off?

A jeweler should have a tool to cut the ring with minimal damage. Any ER or well equipped EMT will have a cutting tool.

All hospitals have a tool they use to cut rings. Check out the link below. There is a guard that goes between your finger and the blade. The blade is turned with a thumb screw. It even has a blade protector for safe storage !!!

As an alternate idea, you might seek out a jeweler in your area. They might be willing to cut the ring for free if you hire them to do the repair work.

If your finger were just swollen you might try windex. It’s amazingly effective. But if the knuckle has grown so much that the ring will no longer pass over it, you will need to cut the ring to remove it.

Wrapping dental floss or thin string around the finger to force the blood down from above the ring works too.

SOLDERING FLUX GRIFFITH SELF PICKLE FLUX 4 OZ

A liquid hard soldering flux for metals which melt under 2000 F (1093 C).

Buy/More Info

Reliable solder connections can only be accomplished with clean surfaces. Using solvents and abrasives to clean the surfaces to be soldered is essential if you are to achieve good solder connections. In almost all cases, however, this cleaning process is insufficient because oxides form rapidly on heated metal surfaces. The rapid formation of oxides creates a nonmetallic film that prevents solder from contacting the metal. Good metal-to-metal contact must be obtained before good soldering joints may take place. Flux removes these surface oxides from metals to be soldered and keeps them removed during the soldering operation. Flux chemically breaks down surface oxides and causes the oxide film to loosen and break free from the metals being soldered. Soldering fluxes are divided into three classifications or groups: CHLORIDE FLUX (commonly called ACID), ORGANIC FLUX, and ROSIN FLUX. Each flux has characteristics specific to its own group. Chloride fluxes are the most active of the three groups. They are effective on all common metals except aluminum and magnesium. Chloride fluxes, however, are NOT suitable for electronic soldering because they are highly corrosive, electrically conductive, and are difficult to remove from the soldered joint.

In metallurgy, a flux (derived from Latin fluxus meaning “flow”), is a chemical cleaning agent that facilitates soldering, brazing, and welding by removing oxidation from the metals to be joined. Common fluxes are: ammonium chloride or rosin for soldering tin; hydrochloric acid and zinc chloride for soldering galvanized iron (and other zinc surfaces); and borax for brazing or braze-welding ferrous metals. Different fluxes, mostly based on sodium chloride, potassium chloride, and a fluoride such as sodium fluoride, are used in foundries for removing impurities from molten nonferrous metals such as aluminum, or for adding desirable trace elements such as titanium.

In high-temperature metal joining processes (welding, brazing and soldering), the primary purpose of flux is to prevent oxidation of the base and filler materials. Tin-lead solder (e.g.) attaches very well to copper, but poorly to the various oxides of copper, which form quickly at soldering temperatures. Flux is a substance which is nearly inert at room temperature, but which becomes strongly reducing at elevated temperatures, preventing the formation of metal oxides. Additionally, flux allows solder to flow easily on the working piece rather than forming beads as it would otherwise.

The role of flux is typically dual: dissolving of the oxides on the metal surface, which facilitates wetting by molten metal, and acting as an oxygen barrier by coating the hot surface, preventing its oxidation. In some applications molten flux also serves as a heat transfer medium, facilitating heating of the joint by the soldering tool or molten solder.
