Any advice on rewires?

[HappyHippyDad]

I have perhaps done 6 rewires now. They are hard work and I wonder if there are ways to make them easier as I have another 2 much larger ones (3 and 4 storey houses) coming up.

I typically take around 2 weeks for a 3 bed house. This is working flat out (by myself) everyday including one or 2 Saturdays and I feel that is a little longer than most of you would take, or is it about right?

I have just bought the metabo mfe40 wall chaser and hopefully that will speed things up. Are there any tips for using chasers? I'm guessing they just make nice neat notches either side of the chase which you then remove with an SDS chisel? Do you always then use oval conduit which you secure to the wall with the oval conduit holders or is there a quicker way?

Cheers all and hope you are having a relaxing Saturday!

Ps.. I'm awaiting the arrival of the triple blade for the metabo, anyone use it yet? Does it actually take out the middle of the chase well?
pps.. What size conduit do you generally use for 1mm, 2.5mm, 6mm, ring etc etc?

Yea, you defo want a pair of hands for some of it, feeding in cables, r just reducing the burden of a house load of chasing in

 

[Dustydazzler]

No to mention , I’m only 42 and my knees , wrists and back are already giving my trouble...after an hour bent over doing feeding cables it takes me 5 minutes to get back up.
I don’t want to be a cripple by the time I reach 50.
there must be loads of youngsters out there looking for work experience, who would be ideal for bashing boxes & pulling cables etc

Most of the rewires I done have been occupied, there is an art to it unfortunately most electricians wont touch them these days.

And if you meant Republic of Ireland their regs changed in 2013, and the last chance to use the old stuff was a couple of years later.
The new regs issue in question was IS 201-4:2013.
Also the CPC is insulated and the same cross-section as the L and N, not reduced like the UK.
But I suppose it could still be classed as T&E but nothing like the UK version and has to be in Conduit.

Romex in the USA/Canada?

Plenty of retired folks out there who are fit and willing-I do such stuff sometimes. You will find that retired folks don't expect hefty pay-packets, will turn up on time, won't spend time on their mobile phones nor insist on having a site radio at full blast all day long. Maybe less keen to work a 10 hour shift, but happy to turn up for a few hours just when you need a hand. You might be surprised how many older folks out there have a bit of experience too. If you have a local branch of The Men's Shed charity, ask them if they have any suitable members. My branch has electricians, decorators, wetpants, CCTV and alarm experts, engineers and metalworkers, woodworkers and plasterers and many other skills. The Shed often has tools and machinery which may be of help if you need some welding or repairs, or just need your chisels sharpened. Tons of experience for not much money.

I did a lot of them on my own, OMG rooms full of furniture , move all in the middle of the room pull up carpets, then cut through 100 layers of lino, lifted minimal floor boards fish wires with my unwound metal coat hanger taped to oval conduit (before all the fancy mech aids you get now lol), repeat same in other rooms, hard bloody work.

 

[HappyHippyDad]

Conduit clips mean the oval stands out a bit far @happyhippydad, not much and anything that do t need to chased us a bonus, as per @Leesparkykent i just drill in behind at an angle plug it and then pinch the oval with a screw keeps it tight till the biding goes over ?

I am intending to try it with wall dog and no plugs just to speed things up a bit more ?

Just updating this thread..

I've purchased the metabo wall chaser with triple blade and used it on a few jobs now.

I LOVE IT!

It takes out the entire chase, without any problem. One member mentioned that he was unsure about buying the triple blade as it may not cut through hard surfaces. It has gone through every surface I have tried it on so far, including red brick. Obviously the depth would make a difference, but I have it set to around 20 (I think), maybe 25mm) which is fine for capping and oval conduit.

The width that the triple blade cuts is perfect for 25mm oval conduit. It fit snuggly in with perhaps 2 mm left to drill a 5mm hole and screw in some concrete screws, no need for wall plugs. I use the pan head concrete screws and the conduit is completely firm.

I cant find the wall dogs @Baddegg, screwfix have sold out. I'm using these from screwfix Easydrive Countersunk Concrete Screws 7.5 x 50mm 100 Pack - https://www.NoLinkingToThis/p/easydrive-countersunk-concrete-screws-7-5-x-50mm-100-pack/1066h
but they've sold out too! It's great not putting in a wall plug.

All you need to do now as a sideline is hire yourself out with it and get your money back.
Mind you I have no idea how much replacement blades are.

try a double glazing wholesalers for those screws @happyhippydad, window fitters use em every where....

 

[mattg4321]

Making me want to upgrade my MFE30 to the 40 now!

 

[HappyHippyDad]

I should add, I've only been using it for a month, so I've no idea of the longevity of the triple blade. Still worth a try though.

Screwfix stock has gone to ---- lately, toolstation had wall digs though when I last got them, luckily my local stores are directly next to each other

 

[Mike Johnson]

Aren't all Toolstations and Screwfix next to each other?

They are in Havant, but I can’t speak for the rest of Portsmouth, the south coast, or indeed, the rest of the UK ??

 

[Mike Johnson]

They are in Maidstone and Sittingbourne, both in Kent, I think it's a bit like Aldi and Lidl once one arrives the others follow on, Oh also like bus's use to be when I travelled by them, can't remember the last time though.

Not on the island @JBW175 bloody miles apart....

 

[Mike Johnson]

Is that the Island of England or the Freezer food outlet.

 

[JBW175]

That’a absolutely disgraceful planning mate, just to rub in, we’ve got Wall Dogs in stock....?

although I still miss going out on Albert & Palmy road, so you win that one. ?

 

[JBW175]

I’m pretty sure that he’s on about the isle of Portsea, and not to be confused with those 6 fingered webbed feet people from the IOW.

EDIT, no offence meant for any 6 fingered banjo players from the Isle of Wight that dabble in electrics.

 

[nicebutdim]

Toolstation only exists online in NI.

Aldi can be found across the Irish Sea or south of the border.

Fortunately we do have internet access, so can see all the nice stuff we can't have.

The colloquial term for them is caulkheads mate.......don’t ask me why ?‍?

I never knew this, but I’ve got a couple of mates off the island so will start using it as a term of endearment for them. ?

Another update to this thread, regarding the longevity of the metabo triple blade.
It's done a further 3 rewires now. The triple blade is removing the chases just as well as when I first started using it. Not entirely sure but I would guess at 5 rewires in total so far over the 1.5 years I've had it.

It is awesome. A standard chase for a socket (approx 2m), takes around 15 - 20 seconds, leaving a perfect chase.

 

[nicebutdim]

Hard to believe it was so long ago that you bought this. Seems like only a few months.

 

[mattg4321]

Anyone know if the triple blade fits the MFE30?

 

[HappyHippyDad]

Anyone know if the triple blade fits the MFE30?

I'm almost certain it doesn't I'm afraid.

 

[nicebutdim]

Both use 125mm blades, with 22.23mm centre.

I've looked into this a few times, but never found a definitive answer..

How hard are the walls you have been using it on?

 

[HappyHippyDad]

How hard are the walls you have been using it on?

They have all been either red brick or stone. They do have a varying depth of plaster on them though, so you are not just going through the brick or stone at full depth. I set the depth to 20mm, this is perfect for 25mm oval conduit which sits snuggly into it and only needs 2 or 3 screws to keep it secure.

So far it does seem to have gone through anything. If the surface is a bit harder, you just go more slowly.

I was certain I'd read a reply from metabo saying you can't use it on the mfe30, but I may be wrong. Best thing for @mattg4321 to do is to contact metabo to be sure.
