Case Studies



stain glass window frame


6 weeks

The Brief:

The original frame had been manufactured from Cast Iron and had subsequently cracked over the years allowing the window to move and the surrounding stone became eroded and worn.

Following a site visit, the Hotchkiss Engineering Group manufactured and CNC machined five 10 metre long stainless steel Tie Bars (70mm x 60mm wide and 10m long) to suit.

A special fixture was set up to heat the bar in order to accurately bend a fork at one end. This was then checked against a tracing paper template from the original by Cathedral staff.
