Flat-lock soldered copper roofing workshop in progress. The
pre-tinned pans have been cleated to the roof deck, which is 1"X12" rough-sawn
hemlock with 30 lb. felt covered by red rosin paper. These pans have a
3/4" fold on the edges and two cleats per side. The pans were pre-tinned
in ruby
fluid to a depth of 1.5" on
each edge. Pictured
below, left to right, are Barry Smith, leader of the workshop, Thomas
Massie, Bill Davis, Robbie McElhatten (in blue shirt) and Tony Foyle
(yellow shirt).
