Right, I need to drop some networking and coaxial cables down from the
loft into a bedroom.

Drilling a hole in the ceiling wall plate is easy from the loft side to
pass said cables through.

half way down the wall is a noggin.

I wish to mount the wall socket lower down than this noggin and run the
cables to the wall socket.

I dont really want to cut a hole in the PB to access said noggin to
drill a through hole.

Is there such a thing as a 1.5m m long drill bit extender I can place
between my wood boring bit and the electric drill?

being able to do this would be a time and a making good time saver!

I once made a long drill for a similar reason out of a long threaded rod.
(Just what I had to hand). Did a bit of crude heating and hammering to
make a simple spear point (a bit wider than the shaft) and ground some
sharp edges on to the spear tip.

Very inefficient but perfectly adequate to drill through softwood.

I reckon given where the noggin is, I'd need a drill bit up to 1.8 m long.

Fortunately for me, the apex of the roof is directly above the ceiling
wall plate I would need to drill.....

Many years ago I did something similar but now, if there was no
alternative, I'd buy or make an extension for a spade bit. However, in
the OP's case I'd cut a rectangle out of the plasterboard with a
multitool, cut a notch in the noggin, drop the cable, replace the
plasterboard (with rear battens), fill, sand and paint.

I have used a copper pipe with a serated end to cut through
plasterboard. Not sure if it would cut through a 2" noggin very quickly.

As a last resort, with flux it is possible to solder onto a steel
woodbit and a brass fitting, using a copper or similar pipe as an extension.

Otherwise Tim's suggestion would be the easiest and least mess.

Kind of - you can get extensions for spade bits that are typically
around 300mm long. Nothing to stop you using several!

(or for that matter use one, and weld it onto the end of a bit or rebar
or threaded rod etc)

If your outlet is going just below the noggin it might be easier to cut an opening in the PB to take a dry wall back box and use a spade bit with one or two extension bars on at quite an acute angle and drill upwards from the opening.

Use a holesaw, but for the extension use pipe. My holesaw (Lidl) has a
19mm nut as part of the arbor which is about 21.5mm across diagonals.
Looks like a 22mm copper pipe could be persuaded to fit.

It's difficult to do this, and you risk damaging the plaster worse than
cutting it. I always used to cut a slot in the plaster. It needn't be
very big and with a bit of skill you can disappear it with polyfilla and
sandpaper. Have you considered dropping the cable somewhere where a cut
in the plaster wouldn't matter, then running it horizontally?

There is an easier way. remove a strip of plasterboard over the noggin,
lay the cable and cover it with plaster then sand and repaint...

Personally I have removed and replaces so many bits of plasterboard in
this house I have lost count.

As long as you have the right paint left somewhere it all comes good in
the end.

You beat me to it. I was actually going to suggest a flexible extender
used from the bottom.

Whatever way the hole is made, it ain't going to to be easy to find it
inside the wall when feeding the cables through. Like others, I would be
in favour of removing a bit of plasterboard at noggin height.

Get a piece of steel conduit of suitable length. Affix a wood boring bit slightly larger than conduit diameter to business end and create a driving attachment for the top to fit your drill. Use this to do the business then remove your cutter and driver. Use the conduit to pass the cable through the noggin, possibly secure the top end of the steel conduit in the loft and leave it there to provide mechanical protection to the cable in the noggin as it's unlikely to be 50mm from the surface.

I agree making the hole is one thing feeding a cable through is another matter even with the aid of a cable rod set. Myself I would not bother with all these esoteric tool adaptions and simply take out a piece of PB across the noggin and patch in afterwards, of course if the wall is papered and avoiding having to redecorate is a must then some of the other suggestions may have their advantages.

I have now drilled two 32mm holes in the top wall plate from the loft above.

I put a LED light down one hole and I can see through the other hole

There is no insulation in the cavity and the noggin/dwang is 142 cm down
from the loft. (so nothing to catch on the rotating drill bit!)

Now the socket I wish to place is 85 cm below this noggin/dwang itself.

I have already used neodymium magnets to locate the PB screws/nails and
I can confirm that they are in the vertical studs and none are present
in the noggin/dwang so there is no risk of a drill bit hitting a

I have fibreglass rods so fishing cable down through from the loft is

Safe zones aren't applicable for the OP's networking and coaxial cables.

I have always assumed that a blanking plate can create a "safe zone" but
the wiki doesn't imply that and intrigued which regulation might allow
it? After all, it might not be obvious it's covering 240V cables.

Personally I'd chop out a square of plasterboard that spanned both sides

Even if you managed to get a 2m drill extension and successfully drilled
a hole without the drill wandering off course you'll have a hell of a
job poking cable through a hole in a noggin half way down a PB wall.

Cut an access hole, get the cable in and fix a support baton to the top
and bottom edges of your access hole, re-fit and attach the PB square,
fill the edge gap and paint; you'll probably still end up doing this
when you've wasted a day trying to drill a hole anyway.

And adding a blanking plate where it turns the corner to comply with
requirements for permitted zones
http://wiki.diyfaq.org.uk/index.php/...lectric_cables

Safe zones aren't applicable for the OP's networking and coaxial cables.

I have always assumed that a blanking plate can create a "safe zone" but
the wiki doesn't imply that and intrigued which regulation might allow
it? After all, it might not be obvious it's covering 240V cables.

I don't think a box + blanking plate meets the letter of the regulations
because they create safe zones "Where the cable is *connected* [emphasis
added] to a point, accessory or switchgear on any surface of the wall or
partition...".

Even if you managed to get a 2m drill extension and successfully drilled
a hole without the drill wandering off course you'll have a hell of a
job poking cable through a hole in a noggin half way down a PB wall.

Not that hard if you have a set of those flexible rods from Aldi/Lidl for
pulling cables through. A bit tricky but I would say definitely doable.

Good point. Too far down the thread to remember it was only a co-ax
cable but still a good idea to follow the practice. Unlike mains if you
drill through an aerial wire or network cable nothing dramatic happens
at the time. Depending how much that cable gets used it could be a few
days before you find the TV's not working or a computer has no
connectivity by which time you don't associate it with having drilled a
different bit of wall and have problems finding the cause of the trouble.

the wiki doesn't imply that and intrigued which regulation might allow

It may not be officially recognised but the presence of a blanking plate
implies there was something electrical there once and there might still
be cables. I would expect anyone aware of the risks of drilling into
cables and who was aware of the concept of safe zones would regard a
blanking plate as indicating the possible presence of cables. Of course
none of this will do anything to protect the person who just blindly
drills into a wall directly above a light switch.

Get a piece of steel conduit of suitable length. Affix a wood boring bit slightly larger than conduit diameter to business end and create a driving attachment for the top to fit your drill. Use this to do the business then remove your cutter and driver. Use the conduit to pass the cable through the noggin, possibly secure the top end of the steel conduit in the loft and leave it there to provide mechanical protection to the cable in the noggin as it's unlikely to be 50mm from the surface.


That is quite a good idea. But would you be able to get the drill bit in
prefect alignment with the conduit?

Steel conduit generally has a 1.5mm wall thickness.

For a 240V installation is that sufficient for mechanical protection?

Doubt it would need to be perfect. A spade bit fitted into a slot cut into
the end of the conduit would probable be €œnear enough€� to go where you
wanted it.

But its network and coax cables... Even if it was mains, surely more than
enough (if you were using standard mains conduit). ;-)

You beat me to it. I was actually going to suggest a flexible extender
used from the bottom.

Whatever way the hole is made, it ain't going to to be easy to find it
inside the wall when feeding the cables through. Like others, I would be
in favour of removing a bit of plasterboard at noggin height.

I agree making the hole is one thing feeding a cable through is
another matter even with the aid of a cable rod set. Myself I would
not bother with all these esoteric tool adaptions and simply take out
a piece of PB across the noggin and patch in afterwards, of course if
the wall is papered and avoiding having to redecorate is a must then
some of the other suggestions may have their advantages.

Richard

Does anyone paper rooms any more?

Yes, I'm aware these are signal cables.

You would think so, but the current thought is there needs to be 3mm of
steel for mechanical protection. Conduit doesn't provide that protection.

I have drilled lots of holes in both studs and joists and
wallplates..... as I was upgrading the room's facilities, I used the
cut a rectangle of PB out and drill said noggin/dwang with a wood bit
and a right angled drill then the whole troom got decorated.

In this case, I already have a fully decorated upstairs room with
laminate flooring that is fully multimedia equipped, but I now need an
extra 2 co-ax and an extra 2 cat6 ethernet.

Put an LED on the end of some bell wire, poke that down so you can see what you're doing. Fiddly but doable.

Been there, done that, got the T shirt!

Thats why I drill two holes, one to poke the LED down, and the other
hoel for tools, cable etc. I then look down the 2nd hole to see whats
going on!
