How to solder stained glass

May 18th, 2012

How to Solder:
1 Choose a well ventilated area and a level work surface. Wear safety glasses and a work apron.
2 Plug in soldering iron (we recommend 100-watt style with built-in temperature control, chisel-style tip, and stand).
3 To wipe the tip clean while soldering, moisten a natural fiber sponge with water and place in the holder on the soldering iron stand.
4 Lay out 60/40 solder and a safety flux.
5 While the soldering iron is heating up, assemble the copper foiled pieces on the project pattern.
6 the pieces together by dabbing flux (using a cotton swab) onto the copper foil at a point where at least 2 pieces meet. Then unwind several inches of the solder wire from the spool. Grasp the soldering iron handle like a hammer, in your writing hand, and remove from the stand. Melt a small amount of solder onto the tip of the iron and apply it to the fluxed copper foil. Hold the iron tip on the copper-foil only long enough for the solder to melt onto the foil, joining the pieces together.
7 Working your way around the project, flux and tack solder all the pieces together, making sure to tack wherever 2 or more pieces join. If a piece is tacked in several spots, it will not move out of position when the finishing seam is being soldered. At regular intervals, wipe the tip of the soldering iron on the moistened sponge to remove flux residue.
8 Once all the pieces have been tacked together, the exposed copper foil must be coated with a thin, flat layer of solder. First apply flux along the entire length of a foiled seam. Then holding the soldering iron in your writing hand, place the flat side of the iron tip on the fluxed copper foil and, grasping the spool of solder in the other hand, place the end of the solder on the tip. As the solder melts, pull the tip along the seam, leaving a thin coating of solder over the foil. Fill in any gaps between the stained glass pieces with solder.
9 gives seams a rounded and even finish. To do this reapply flux along one seam. Place the narrower side of the iron tip onto one end of the seam (the flat side will now be in a vertical position), keeping the tip in contact with the seam at all times. Holding the solder to the tip, slowly draw the iron along the length of the seam allowing the solder to build up only enough to create a slightly raised, half-round seam. When the solder begins to build up more than necessary, pull the strand of solder away from the tip. Draw the tip along the seam until the molten solder levels out more evenly. It will take a bit of practise to determine how quickly to move the iron and how much solder to apply. Because glass can crack if it is heated too much, don’t go over a solder seam too many times. Allow the area to cool while you solder another seam. Flux and bead solder the remaining seams.
10 Turn the project over and tin and bead solder each seam on the reverse side, as described in the steps above.
11 To finish the outside edges of a project that will not be utilizing a rigid metal border (zinc or lead came), flux and tin all exposed copper foil on both sides. Holding the project in a vertical position, bead the edge by applying a small amount of solder and then lifting the iron off the foil long enough for it to cool before adding more. Use a touch-and-lift motion rather than drawing the iron along the edge. This will prevent the copper foil from becoming too hot and lifting off the edges of the glass. Repeat around the outside perimeter of the project. (Other methods of finishing the outside edges will be demonstrated in various projects throughout the book.)
12 Remove excess flux residue quickly to eliminate oxidization and a tarnished look.

How to apply copper foil

May 14th, 2012

1 All pieces of glass must be clean and dry before being wrapped in copper foil or the adhesive backing will not stick to the edge of the glass.
2 Choose the backing and width of foil best suited for the project. Use regular foil (copper-backed foil) if seams are to be treated with copper patina, black-backed foil for black seams, and silver-backed foil for silver seams.
NOTE:
We often use black-backed foil regardless of the color of the seams because it gives the appearance of a shadow and is quite unnoticeable.
Copper foil is available in various widths-1/8 in to 12 in-the most commonly used are 3/16 in, 7/32 in, and 1/4 in. For most projects in this book, 7/32 in foil is required. When a single piece of glass varies greatly in thickness, use a wider foil and trim it evenly with a utility knife.
3 Peel 2 in to 3 in of the paper backing away from the foil and lightly grasp the foil between your thumb and index finger. The adhesive-covered side should be facing upward. With your writing hand, center the edge of the glass on the foil, leaving an equal amount of foil showing on either side of the piece. Fold the edges of the foil over and press firmly to the glass. Foiling should be started at a corner of the piece that will be positioned towards the center of the project.
4 Hold the glass piece in your writing hand, perpendicular to the work surface. See photographs. Press the foil onto the glass by sliding the middle
and ring fingers of your opposite hand along the edge. Let the foil slide through the thumb and index finger, automatically peeling the backing off the foil. You should have a clear view of both sides of the glass as the foil is being applied. Continue wrapping the foil around the entire piece, making sure to keep it centered.
5 Once the entire piece has been wrapped, cut the foil with a utility knife or scissors, overlapping the starting edge approximately 1/4 in. Crimp (fold and press) the edges of the foil onto the surface of the glass, using a lathekin or a piece of wooden doweling.
6 Burnish (press and rub) the foil firmly to the glass along the perimeter of the piece and the edges of the foil. This will ensure proper adhesion to the glass when heat is applied to the copper foil during the soldering stage.
NOTE:
Orange peelers, pencils and pens, popsicle sticks, can be used successfully to burnish foil.
7 Trim excess or overlap with a utility knife.

How to prepare beveled glass

May 13th, 2012

1 Beveled glass that is precut can be purchased from your local glass dealer. Verify that the bevels fit the pattern and grind (p26) to fit if they do not.
2 Take care not to scratch the glass bevels. Keep work surfaces clean. Place masking tape over the raised surface of the bevels for protection from scratches.
3 Apply the appropriate copper foil (p29) to the edges.
NOTE:
This procedure also applies to purchased jewels, glass globs or nuggets, and rondels.

How to prepare mirrored glass

May 12th, 2012

1 Always cut mirrored glass on the glass side, not the silvered side.
2 Bevel the coated side of the mirror by holding it at a 45° angle to the grinder work surface, with the silver-backing facing up, and lightly grind each edge. Beveling will help prevent chipping the silvering during grinding.
3 Grind mirror, if required, to make it fit the pattern. Keep the grinding surface clean to prevent scratching the silvering.
4 Rinse off grinding residue with clean water and dry with a soft cloth.
5 Apply clear nail polish to the edges of the mirror to prevent flux or patina from seeping between the glass and the silvering. Allow polish to dry.
6 Apply the appropriate copper foil (p29) to the edges.

How to drill a hole in glass

May 11th, 2012

How to Drill a Hole.
1 With a permanent waterproof fine-tipped marker, mark the glass piece where the hole is to be drilled. Holding the glass at an angle to the top of the bit, begin grinding the hole. Hold the glass firmly but do not apply too much pressure.
2 Once the hole has been started, level out the glass piece and continue to grind completely through the glass. Wet the bit often with a sponge soaked with water and/or grinding coolant.
NOTE:
If the glass is opaque and you cannot see where to grind the hole, make a template of the glass piece from stiff cardboard. Make a hole large enough for the drilling bit to fit through. Tape the template to the underside of the glass. With the template facing downward, drill the glass, using the hole in the template as your guide. To preserve the template for later use, remove it from the glass once the hole has been started.

How to Grind Inside Curves

May 10th, 2012

How to Grind Inside Curves.
Using a Drilling/Grinding Bit.
1 Wear safety glasses and a work apron. Grasp the glass piece firmly in your writing hand and grind away excess glass by holding it against the bit with a light and even pressure. In the other hand, hold a moistened piece of sponge lightly against the bit to keep it wet.
2 Check the piece against the project pattern and mark where further grinding is required. Repeat until the piece fits accurately.
NOTE:
An elevated platform, used as a surface on which to rest small glass pieces when using drilling bits for grinding, is available for most makes and models of grinders.

How to Grind Glass

May 9th, 2012

1 Wear safety glasses and a work apron, have a face shield attached to the grinder, and position a back splash along the back and sides of the grinder to contain any airborne glass chips and water overspray.
2 Keep water in the reservoir and have a moistened sponge positioned adjacent to the diamond-coated bit at all times.
3 Cut each glass piece on the inside of the pattern line to fit the pattern with less grinding and allow for the application of copper foil. If the glass pieces fit the pattern and do not overlap the pattern line, make one quick swipe against the grinding bit on each edge of the glass to dull any sharp edges. Only light pressure is required when pushing the glass against the bit.
4 If traces of the marked line are still visible on the piece, grind the edge to ensure an accurate fit within the pattern lines.
5 Check the piece again with the pattern. If any part of the piece still overlaps, mark the area with a permanent waterproof marker. Grind the excess away. Check the piece with the pattern. Repeat until the piece fits.
6 Repeat steps 3 through 5 for each piece, making sure to leave a very narrow space between the pieces to accommodate the copper foil. Pieces that leave a large gap between the line and the adjacent piece should be recut.
7 Rinse each glass piece under clear running water when grinding is complete.
8 Wipe the surface of the grinder often with a wet sponge or cloth to prevent small glass chips from scratching the underside of the pieces being ground. Do not run bare hands across the grid work. Glass slivers are painful and difficult to remove.
9 To ensure proper performance of the glass grinder, clean thoroughly and rinse the water reservoir after each use.
NOTE :
Keep the pattern sheet dry during the grinding stage by placing it inside a vinyl sheet protector or cover it with an adhesive-backed clear vinyl.

Scoring and Breaking S-Shaped Curves

May 8th, 2012

1 Trace pattern F (p21) onto the glass, placing one of the sides against the edge of the glass.
2 Score the most difficult cut first (S-shape).
3 Align the running pliers with the score line. Squeeze only hard enough to start the run. Repeat the procedure at the opposite end of the score line If both runs meet, use your hands to separate the resulting 2 pieces. If the “runs” do not meet, gently tap along the the score line (on the underside of the glass).
4 Score and break out remaining cuts.
Grozing:
The jagged edge of the glass along the score line can be smoothed by grozing.
1  Grasping the piece of glass firmly in one hand, place the combination pliers perpendicular to the edge of the glass and drag the serrated jaws along the jagged edge in an up-and-down motion. Repeat until the edge of the glass is smooth.

How to cut outside curves, circles, and ovals in glass

May 5th, 2012

Cutting Outside Curves, Circles, and Ovals .
1 Trace pattern C (p20) onto the glass, leaving 1/2 in from the outside edge of the glass.
2 Make an initial score line that will separate the pattern piece from the sheet of glass. The score line will go from the outside edge of the glass and* upon reaching the circle will follow the perimeter of it for a short distance and then head off on a tangent to the edge of the glass (see line 1). Break away this piece.
3 The second score line will follow around the circle for a short distance (approximately l/6th of the perimeter) and then leave on a tangent to the outside edge (see line 2).
Break away this piece.
4 Repeat step 3, scoring and breaking the glass in a pinwheel fashion, until the circle shape has been formed (see lines 3, 4, 5, and 6).
5 Small jagged edges where a score line was started or ended can be ground off with a glass grinder or nibbled away with breaking or combination pliers.
6 To practise cutting outside curves and ovals, trace pattern D and E (p20) onto the-glass, leaving 1/2 in from the outside edge of the glass. Follow steps 2 to 5 above.

Cut inside curves stained glass

May 4th, 2012

Cutting Inside Curves.
Inside curves are the most difficult cuts to score and break out successfully. Attempt the most difficult cut of a piece first, before cutting the piece away from the large sheet of glass.
1 Trace pattern B (pl9) onto the glass. Position the outer edges of the curve so they align with the edge of the glass.
2 Score the inside curve of the pattern piece but do not attempt to break it out at this time.
3 Make several smaller concave score lines (scallops) between the initial score line and the outside edge of the glass.
4 Using breaker or combination pliers, start removing the scallops, one at a time, beginning with the one closest to the edge of the glass. Use a pulling action with the pliers rather than a downward motion. Remember to position the jaws of the pliers at either end of the score line and not in the middle.
5 Continue to break away the scallops until you reach the initial score line. Remove it and proceed to score and break away the pattern piece from the large piece.
NOTE:
The tapping method of running a score line can be used, with care, to break out stubborn pieces.
