Which tool to chase walls for wiring (Ed.)

[jcaan]

One thing though the 3socket - where does that surface mounted trunking come from/ go to because by the looks of it its single trunking indicating that the 3 socket is perhaps already a spur so you cannot run an extra socket off it but you can use a flexible extension cable.

That's a great idea about hhe extention.... might be an easier job..

Yeah it looks like the socket is spured to the side of the breast where there is a switched fuse box. It might have been for the TV for the previous occupants . I'm not sure

Angle grinder in one hand, vacuum cleaner in the other. Same technique for an SDS drill, but easier with an assistant. Wall chase tools exist, with a hood that has a port onto which your dust extraction device can be attached. They're little more than a fancy angle grinder with multiple blades

NO NO NO the moment the disc goes into the wall the room will be filled with dust and even 4KW industrial vacuum machines will go nowhere near collecting it.

So when would you use an angle grinder ? Different type of wall ie plaster boards etc?

Or is it because the room has carpet in it. That's why we should stay away from it for now?

 

[robinbanks]

if you use a standard vac with it you will also kill the vac

Nonsense. Chasing those slot edges out will generate about a couple of tablespoons of dust. If a vac bag/bagless can't handle that without blowing up it'd be useless for cleaning an average sized house

NO NO NO the moment the disc goes into the wall the room will be filled with dust

Nonsense. Try it. In case I wasn't clear/it wasn't obvious, the nozzle of the vacuum cleaner needs to be held near the exit wound of the cut, not laid in the floor somewhere over the other side of the room.

And not some asthmatic, worn out, half charged old Dyson cordless that's chock full of pet hair, in case that wasn't obvious either

So when would you use an angle grinder ?

Practice on a concrete block outside/in the garage. It doesn't matter what you cut, anything hit with a diamond cutting wheel will become dust quickly

You're free to stop at any time if you think it's making too much mess, or not even start if your practice runs outside put you off..

basically the chimney is a brick built box with a substantial void in the middle

That's a great idea. I'll practice outside just to see how I get on with things. Infact it's always a good idea to get some experience in things whether it works or not.

Thanks but I don't quite understand the diagrams you have just posted ?

I've used angle grinders for decades And I would not wish to put a novice through the mess that will be created in a lived in house. I understand exactly what you advocate and very experienced with the process for drilling, powered chiselling, woodsawing but not a cutting disk in plaster/brick walls.
I mentioned the 4KW vacuum earlier which is a popular machine with builders who will make the same claim as yourself to customers before filling their property with grit.

Angle grinder in one hand, vacuum cleaner in the other.

Have you ever actually done it? Last time I tried it, in an 'occupied'(my!) house, I almost ended divorced

 

[JohnW2]

So when would you use an angle grinder ?

It's the quickest method but, having learned my lesson, would these days only contemplate it in an essentially unfurnished (including no carpets) house,ideally unoccupied - otherwise the time one takes in trying to clean up will more than cancel the faster creation of the chase!

... and, if (despite the above) you did try a grinder (with or without a vacuum cleaner), you should wear a decent mask.

Kind Regards, John

I see but what's the propose of this ? Sorry I'm novice . I am good at DIY . But no quite understanding the reason behind this ? Is this just ti check if there's a void within the chimney ? Or where the wires should go through ?

run the cables through the top hole into the void and out through the bottom hole.

It saves a lot of time, effort and mess (as long as it works)

Wouldn't it be a better idea to lower the hole on the side so it's closer to the switch fuse box. So I can just spur of that and put socket where you have said at the front ?

Often. Prefer wet cutting, but sometimes one needs to make a dry cut

Experiences obviously vary

'Wet' is obviously a good approach, but probably not appropriate for the OP's situation.
