sinking plug sockets into walls...

I have a feeling those ones only work in soft blocks rather than hard brick...

[Dave Plowman (News)]

I've a feeling none of them have a decent life with any bricks...

[Steve Firth]

Eww no.

The one I use is on that page:

39281 SDS Plus Brick Removing Chisel

[Brian Sharrock]

I'm open to correction; but I _think_ that 'brick removing chisel' (it's quite thin) is for chipping out the mortar between and around bricks to permit a brick-sized aperture to be opened -rather than 'planeing a brick. I use the cranked chisels - sort of shovel shaped ends to 'plane' the back surface.

BTW is the purpose of the mortar to join bricks togehter or keep them apart?

[Steve Firth]

It's not that thin, and would only be good for chopping out the mortar on a modern (i.e. far too deep) layer of mortar.

It's not like it's going to break if used for something else and it's perfect both for chasing in and cutting boxes in brick. If you look at the enlargement you will see the design is very similar to a scutch chisel which is used for dressing masonary.

The one referred to is easier to use IMO. Also available in TCT if one is intending to do a lot of work. It can be used with the tool at 90 degrees to the back of hte box and it's possible to get a good level finish. They are also much sturdier than the box sinkers.

As far as I can tell on modern brickwork it's to make the job cheaper by using fewer bricks.

I may need that sometime.

Hi agian guys,

I have done the boxes, I used my trusty hammer and chisel, and occasional normal drill bit... no other tools, managed to have a box cut out and attached within 20 minutes or so, with relatively little stress or extra cost. All pretty neat and tidy too!. I went for teh tight option then chipped away to make the box fit snugly, screwed it into the brickwork, filler around it, ajob done!

Thanks again for all the advice!

Tom
