Power Supply to Garage

Better than one of my apprentices idea of drilling though a 1.22m wall with a 1m long drill bit.

"Drill from both sides and hope that the 22mm holes meet in the middle".

[ARW]

Richard is probably wanting to do the job properly.

[Adam Funk]

Isn't there a saying like "measure twice, drill, um as necessary"?

Where can you buy a drill bit longer than 1 m? (I mean for normal power tools, not for drilling for oil.)

[ARW]

Far too much time with them for my liking.

[James Wilkinson Sword]

Properly means it works.

I managed to get a set of 1.5m Silverline ones off ebay.

That's what they did with the Channel Tunnel - and succeeded

And Crossrail. The footage of the moling machine breaking through at Farringdon is pretty impressive.

Not with a 13 mile x 22mm SDS drill bit and a brain dead 18 year old armed with a 850W Bosch hammer drill.

[Adam Funk]

Did you have them *before* the apprentice tried that approach?

[Tricky Dicky]

Thanks to all contributors, I take it that my timber beam spanning the gap will be OK to support the cable and I can use whichever of the three propos als. The image of Adams apprentice making Swiss cheese of a wall trying to get holes from each side to meet will stay with me forever.

Indeed, but I think they had access to better technology than the average oik trying to drill a 22mm hole through a 1m thick wall.

(Which I have to do in order to install some more exterior lighting. But I'm going to hire a long drill.)

[ARW]

No.

Some people say that T&E should not be clipped direct outside as it is not UV stable.

So if you want the T&E route use a bit of conduit (with drain holes).

[Tricky Dicky]

Thanks Adam.

Well, to be fair to the apprentice, he may have been doing the best he could with the equipment he had available, although I'd like to think that in that situation I'd ask the boss for advice.

[ARW]

Agreed. To be fair at least he had a go. Better than the other ones that have no initiative. And the one with the drill bit did qualify and become a pro in record time.

"The person who doesn't make any mistakes doesn't make anything." ;-)

[Judith]

Perhaps he'd seen how the channel tunnel was made ;-)

[ARW]

Maybe.

But I know the bloke that managed to get Dodworth and Redbrook collieries coal drilling machines to meet up only 2 feet apart in the early 1970s
