After the entire panel has been cut out and laid on the duplicate pattern, it is ready for assembly. David assembles the windows using the traditional method of assembly by lead caming, almost exclusively. We assemble the window on the original cutting pattern for accuracy. A piece of glass is laid on its space and then a segment of lead channel or caming is wrapped to the edge of the glass and held in place by glazing nails. Next, the adjacent piece of glass is placed into the channel, held with nails and then wrapped with lead. Pieces of glass are adjusted with grinder and grozing pliers, continually making sure that the window does not expand.This process is repeated for each piece of the panel until all the glass pieces are held in the lead matrix. A specialized border channel is added to the edges of the window to allow for some small adjustment to the overall size during installation, if necessary.
