Wondering what has worked well in the past for you guys WRT putting rework boxes into old plaster walls with that annoying steel mesh inside them. Looking for the best way to avoid chipping the outter surface so it is a clean job. I was planning to trace, drill, and then use a recip saw with steel blades. Any suggestions?
The rotozip works nicely for cutting out the plaster. After that I like to use a half-inch speed bit and make a little 'swiss cheese' in the lathe, then use dykes to cut the lathe out. I also prefer using metal cut-in gem boxes instead of the plastic ones because the metal box isn't as big as the plastic and the hole to be cutout doesn't have to be as large if I were using a plastic box. Did the make any sense?
Screw driver and kleins for me too. Chip away around the sides then bash in with hammer. Then cut the mesh with side cutters. I allways tell the customer their is no guarantee with plaster as far as damage. I allways have been lucky.
