Chasing Walls And Sinking Back Boxes

[Apache]

Guys - what methods do you use?

These any good? http://www.screwfix.com/p/armeg-ebs-back-box-wall-chasing-installation-kit-7-pieces/67733

Wall chasers?

Unoccupied building.

little kango,

or one of these if your budget doesnt stretch,  I use something similar, but cheaper, disposable tbh, then buy another one,

Depends hlow hard the brick is really

F hard brick like Accrington or Blue Staffy.....use apprentice

Normal,interior stock, 7kN block.......angle grind sides, remove waste with tile chisel in SDS. Armeg may be ok

Clinker block, soft southern bricks, thermalite.....Armeg

Scut h chisel,in an SDS after chain drilling sides is effective, causes less dust in air if used with vac

Last resort......lump hammer and scutch chisel, tidy sides and corners with electricians bolster NOT flooring chisel. Different animals all together

Just having done 30 odd fricking years of it..........done little in last 10 years. Luckily

I have the predecessor of this:

http://www.screwfix.com/p/erbauer-erb383wch-125mm-wall-chaser-230-240v/58708

Combined with a 2kg Bosch mains SDS & a 36V Bosch battery SDS, both with roto-stop, obviously!

Also a bolster & club hammer, & a Henry to connect to the wall chaser.

Don't forget your PPE though seriously, gloves, eye, hearing & respiratory protection.

I use one of these:

You can get ear defenders to go on it.

TBH when using the chaser, I would never be without full PPE, even with the extraction from the Henry.

Depending on the construction, I have toyed with one of the kits containing various versions of these:

http://www.screwfix.com/p/armeg-ebs-double-box-cutter/64983

However, these are only suitable for certain buildings.

Normally, mark out the wall, chain drill, cross drill, then break out with SDS for boxes

However, I do this barely once a year, IF I HAVE to, most of the kit I use for other jobs, bar the wall chaser, which I have used on one job, and it has paid for itself to be honest, in the savings on my body.

I can't "do" hammers and chisels for long any more, my hands go numb too quickly.

HTH

I bought a brilliant tool of an ebay bloke

It is an SDS scutch type chisel,BUT it is as wide as a single box, as dlong as half a single box and 25 mm deep.

Fantastic tool,BUT i think he may have stopped doing them

I am off to find a link for them...

I have one of those wall chasers,

talk about DUST,,,,!!!!!!  even with a hoover [other makes are available]

Ive used it twice,

not for me,,,,,,

Those Armeg things are OK on softer brick as said , Patche,  I use an SDS  drill switched to hammer with a scutching chisel in it ....also a normal SDS chisel and also lump hammer & bolster . 

Good to have a cheapo grinder back at base to keep them sharp.

 

[Apache]

First job is a petrol stone saw to open a doorway through a double skin wall. I'll find out what the construction is pretty quickly from there.....

There will be dust.

I have a larger (6kg) roto stop SDS that I got for little money from B&Q a lot of years ago and is still going strong. I also have a 2kg Dewalt one from SF that is quite a mean beast. I looked into hiring a chaser, but the hassle would make it simpler to buy one if they do what they say. I have a small dust extractor vacc and a Record drum affair. I do have the predecessor of the Trend full face mask that SW links - used to wear it woodturning.

 

[steptoe]

are you chasing into stone?

if so, forget that thing you linked to,

only answer is a grinder/sthil saw and diamond blade followed by a 'kango',

 

[Apache]

stone on the outside. 100 year old building. Will have a better idea when I have my new door what I am working with.

I guess it could be brick internally.

 

[steptoe]

if you are going to chisel stone,

WEAR GOOD GOOGLES

 

[Zeespark]

Dont quote Me on this people, but I have had a word with Armeg regarding their new round chasers, they seem to think the new type can be used for bricks, unlike their old rotary cutters. :innocent

C4 or wrecking ball.

then get the wall re-built with a space for the box

 

[Sharpend]

Make it the modern look, surface sockets run in galv conduit

You been round to OnOff's gaff!

Guilty! Got to love a chaser (and tube)! I've got a couple and they're magic used with a big vac - I have an oil drum sized dust extractor with a 3" take off, 2300W I think. To my mind it's near dustless but if you forget to let go the trigger before you lift off then you'll be rewarded with a cloud of dust whatever - even with the vac going. And the chasers never get right up to the ceiling or behind coving. If chiselling with the SDS then I wedge the rubber end of the vac hose in the chase but it's never going to stop the bits that ping off. 

Got the Armeg box sinker kit. Undecided tbh. I often end up drilling a matrix of holes where the round cutter won't touch it then squaring up with the box sinker.



Cut this chase with the multi-tool tbh the block was so soft. It was touch and go whether the whole corner of the wall fell off so the tube acted as reinforcement:

Is that so you can have no RCD on lighting or is there a reason for the metal conduit? I was just going to put capping over the cable to protect from filling in.

 

[M107]

I have a wide sds chase tool & Zee's prototype 10mm one that is nicely bent for getting behind skirting board or coving. But still use the scutch & bolster as well

I need to design a tool that will find cables & boxes behind plasterboard & celotex......................don't need a tool to install board or celotex, that's called the builder!! new thread coming up in the your pictures section.
