Advanced Portable Machining, based in Calmar, Alberta, Canada, repaired a 192-inch (4876.8 mm) support ring inside a vessel 5 feet (1524 mm) down. The ring was overlayed with stainless steel and needed to be machined down to specification. Foot supports were built as the CLIMAX CM6200 circular mill was past the max clamping distance. Each cut took 1 hour to complete. Three rings to complete, 18-day job.
