I was recently asked about the installation at First Presbyterian Church, Edmonton, which John completed over 6 weeks this summer – I was gently reminded that I had promised a post with more details! So, apologies for the delay….here we go….
We would also like to take this opportunity to thank all involved in this project and congratulate all on the preservation of this historic window.
Installation underway; two thirds of the traceries in position.
Detail of installed traceries during re-pointing process.
Installation commencing on the main lights.
Detail showing different widths of brass support bar used, and the multiple copper ties used to secure the window to the bars prior to pointing. Note that the larger 5/8” brass bar to strengthen the lap-lead joints where the panels interlock. The lap leads are specially manufactured wide heart and u-shaped lead came, which spread the weight and tensions on the window evenly. They interlock similarly to “tongue and groove” joints.
