Thanks gents!

sawsall and angle grinder it is. Hope to find some scrap coping this week. Appreciate the help.

Also is there really a great risk of collpase with the water out? The pool was built in 1979, 18x37 grecian. very large poured concrete decking that hopefully keep moisture out from behind the vertical walls. This repair and some other small wall repairs as well as liner replacement will require 1 week with water out. it has been down below the vertical walls for the past day without any visible issues.

thanks!!
