Glazing: Wood Beads Instead of Putty

These can be used in place of weathering putty, but the glass should be set in bedding putty. Bead can be square, splayed or quarter-round softwood. It is fixed with 19mm-25mm panel pins and glazing felt. When using wood beads, a slightly thinner glass can be used.

Measure the sides and tops of the rebates and check the diagonals for squareness. The four beads should be cut slightly over size; mark these in pencil to show the respective positions. Mitre the ends, using a mitre box and dovetail saw. Paint the backs of the beads with a. primer.

Lay the beads flat and gently tap two panel pins part of the way into the centre of the bead at about 25mm from the face of each mitre. This will establish the angle of entry for fixing into the frames. Remove the nails and drill holes; this prevents the beads from splitting. Drill further holes at about 15mm distances along each piece.

Put the beads into position and gently tap down the pins, just to the face of the beads.

These are not fixed permanently until all four are in position. Fix first the upright, next, the opposed bead and then top and bottom beads; check also that the glass remains accurately in position.

With a centre punch, tap the pins below the surface. The holes can then be filled with putty or a filler, and any inconsistencies in the mitres made good. Then the bead can be rubbed down, prepared and painted.

Glass vibration, which can be noisy and even cause glass to break, can be avoided by using adhesive glazing felt in place of bedding putty. This is cut to length and set into the rebate before fitting the glass.

With thicker glass or in larger areas, cups and screws can be used in place of panel pins. If made of brass or white metal these can look attractive, particularly on natural or varnished timber.

If cups are not used, the screw pilot must be recessed with a countersinking bit. First drill the pilot hole; this is unnecessary where cups are used.

Countersunk heads should be recessed below the surface of the beads. To fix, position one of the side beads and make a hole through the pilot hole into the frame with a bradawl, and fix in the order used for pinned beads.

Brass screws fixed through hardwood should first be lubricated with candlewax to prevent them from snapping off.
