What's the problem with plastic capping ?

Personally I'd use oval conduit in chases as they only have to be half as wide then

yes, it is, biff. the plaster is very thin in places and the bricks have destroyed 2 diamond angle grinder blades. the walls are being papered anyway. so rip away.

have used tube where possible, but in some places the plaster is so thin that the clips would have been proud.

anyway, where the capping can be seen, there is just about 1mm for a skim with finish. so ner, ner.

I use a metabo chasing machine that cuts a chase 25mm wide and 25 mm deep , then remove the middle with a chisel in the multi drill , then install cables in 20mm round conduit with conduit just into the 20mm holes in metal boxes , plaster with one coat plaster and reskim and smooth of with trowel and water spray , , this leaves the conduit 5mm below surface , when I'm finished its ready for decoration ...

I find that anything less than 5mm may cause the plaster to crack if too thin in the future..

ideal method when you can do it. not recommended for a lived in house though. enough dust to fill a skip.

I do this in any house , I also attach a henry vac to the spout on the chase , the dust you get is when using the multi drill , but then you would get that anyway , still its a lot easier and cleaner than other ways I have tried , The chase machine has a spring loaded hood that sits flat on the wall so forms a good seal for the vacuum to work so its really clean . along with dust sheets as normal of course ...

I am doing a job at the moment so will post some pics later next week..

i dont understand why we need to cut chases out deep enough to bury conduit for a house rewire ?

seems like alot of unnecessary work and mess when you can just chop back plaster and clip direct.

i do mine about 30mm wide. thats a little bigger than my cold chisel lol.

clip down wall and job done (boss wont pay for conduit when we do houses, the work is just to keep us busy)

Because I was taught to use oval conduit in chases in existing walls by my mentor when I was an apprentice, and until I hear of a good reason not to I will carry on doing it this way.

I'm not condemning anyone who does it another way, or saying that my way is best, it's just the way I do things.

the main reason i use tube or capping is to facilitate rewiring of a drop if some muppet drills or nails it.

and how many times in say , the last 5 years , have you been called back to a domestic job you've rewired where a cable that is within the permitted zones , has been drilled through ?

im gonna guess its not often enough to justify automatically installing conduit on every job you do.........

my stepdad is an engineer but a thick one.

he starts drilling stud wall for a picture, he hits something solid so he pushes on harder till he has drilled through it (socket on other side of stud wall)

how he missed the cable i don't know

I thought you were meant to fill the knock out boxes half full of plaster as well?

ugh I know what you mean
the last job i was on chasing down problems i found 4 boxes completely filled with plaster. spent quite a bit of time entertaining my apprentice with some very colourful language:cuss: :furious3: LOL.
