On 25/12/2003 "Robert Irwin" opined:-
Need some kit for making a better appearance to my cabling work, I'm after
kit for digging grooves into walls so I can bury a couple of power cables
in the walls before being plastered over again. Having trawled
various DIT sites I've come across horrifically expensive 'wall chasers'.
Are these the best bits of kit for the job, and anyone know good soures of
them? Or for a shallowish groove in wall is an angle grinder okay? Also
wondering if anyone know of tools for digging holes to fit flush-mounted
sockets out easily, or is it just a case of whacking away at it with a lump
hammer and chisel?

A grinderette fitted with a stone cutting disk will cut a channel in
masonary, cutting a series of slots. For boxes, simply drill lots of
holes with a masonary bit/hammer drill where you need to fit the box.
Then expand with a lump hammer and chisel hitting sideways, rather than
straight at the wall.

The danger with thumping at right angles, is that you might well knock
bricks right through the wall.
