There are loads of useful threads on here for chasing cables, but
there are a few things I haven't been able to find an answer to.

Firstly, my aim:

To hide the power cable and AV cable (a single cable which splits at
both ends, one with a DVI like plug, the other an audio plug of some
sort.) from the plasma TV to the cupboard at its bottom right (length
of cable only 3m, we're not talking vast distances). I am planning to
chase the cable into the wall, and take it to under the floor boards,
then go along literally only a metre, and then back up through the
floor boards to the cuboard, and there the power socket/media box. I
will probably hire a diamon chasing machine such as this:

http://www.hss.com/Fae.asp?sysPage=w...sysLanguag e=[BASE]&resetToGroup=YES

My plan is:

1) Remove one sheet of the lining paper which is there

2) Cut the channel with the above tool

3) Chisel out the channel with a hammer and chisel (bolster chisel I
presume?)

4) Put in some kind of plastic conduit which will allow the cable to
enter laterally (rather than threading through) as the plugs are
bonded plastic, and wired in a proprietary manner, so wouldn't want to
have to cut them off and replace!

5) Thread cable through floor board and ensure there is enough slack
both at the TV end and the cupboard end.

6) Use some kind of filler (polyfiller?) to fill in the channel.

7) Wait to dry

8) Sand as smooth as I can

9) Paste and cover with new lining paper

Done... Yeah right!

The problems I forsee, and need your advice with, a

1) How do I know the wall is strong enough for the plasma?

2) I am not sure what to do when it gets to the skirting boards. They
are pretty old (probably 1900-1905), and I can't see an easy way to
pry them from the wall. They are a good 100-150 mm high, and 15mm
deep. I just need to get that extra distance *behind* the skirting
boards, down into the floor board void (which I can get to with the
huge 1 metre crawl space underneath)

3) I am also worried old plaster/brick won't fare well with the
chasing

4) As I mentioned before, the proprietary cable has two quite wide
plastic bonded plugs (about 40mm width), so any holes will need to
accomodate that)

5) Will I be able to get a flat enough finish with polyfiller, at
least after it's covered with lining paper?

6) How can I line up the new lining paper with the old? Obviously
going to repaint but is it best to redo the whole wall? Or even
replaster?

Any advice greatly appreciated.

Thanks

Are you sure this is proprietary? It would be so much neater if
you could have the chased cable ending in a wall plate at each end
that you can plug into.

Anyway, I haven't got answers for all your questions, but I've been
doing a lot of chasing to upgrade the place we bought.

Get a long drill bit and drill down at as close to parallel with
the wall as you can behind the skirting board - don't try to remove
it.

You'd be better with a bag of one-coat plaster - certainly going to
be cheaper. Covering over a single chased duct it is fairly easy
to get flat enough.

The video part is definitely DVI, but I'm pretty sure the wiring
inside it is proprietary. It would be quite a task to wire up a DVI
wall socket, if indeed one existed. Also, I've no idea what the audio
part is. Never seen a plug like it.

Have had a good look for DVI wall plates, and found this:

Still no idea about the wiring, I guess the chased in part can be the
normal wiring, but you'd still have to do it for the patch cables, or
vice versa.

Also no idea about the audio part...

The connectors are, if I remember correctly, a DVI-D and a DFP-MDR20. both
are video grade connectors, the DVI-D carrying picture and the DFP (digital
flat panel) everything else.
If it's a problem, pioneer do a 10m cable too, but sit down before you ask
how much it is......... Whoops, seen where picture was, obviously you know!

Mind you, if your choice of supplier was any good, they could have answered

I would have though it simpler to put in a conduit large enough to take
the connectos as well. If you don't then you may be able to get the
cable in there without cutting it - but it won't come out again
otherwise. Look at CPC - the do conduit and trunking in all sorts of sizes.

5) Thread cable through floor board and ensure there is enough slack
both at the TV end and the cupboard end.

6) Use some kind of filler (polyfiller?) to fill in the channel.

7) Wait to dry

8) Sand as smooth as I can

9) Paste and cover with new lining paper

The problems I forsee, and need your advice with, a

1) How do I know the wall is strong enough for the plasma?

How heavy is the plasma? What is the wall made out of? It it is any form
of block work it should be fine. If it is plasterboard (or lath and
plaster) over studs then you may need to locate the studs for fixing to,
rather than the gaps.

2) I am not sure what to do when it gets to the skirting boards. They
are pretty old (probably 1900-1905), and I can't see an easy way to
pry them from the wall. They are a good 100-150 mm high, and 15mm
deep. I just need to get that extra distance *behind* the skirting

Get a 'kin big drill bit. One of the Screwfix 1m jobbies will get you
behind pretty much any skirting. You can also get special channeling
chisels for SDS drills designed to reach down behind skirtings.

3) I am also worried old plaster/brick won't fare well with the
chasing

If cutting with a disc based chaser then it will be fine. Using a
ordinary chisel on a SDS is also usually OK. Using a channeling chisel
on an SDS is quick but will cause more collateral damage on flaky plaster.

You can buy an angle grinder for £16 from screwfix.com, and diamond
blades are 3 for £11 from toolstation.com - you'll only get through
one.

Seems a lot of work for such a trivial thing though.

Does all the route of the proposed chase sound solid or hollow when

when you start to chase through it...

Only you can answer that, as it's a learnt skill involving the

how much extra water you spray on when smoothing.

By removing "a strip" do you mean a full roll width or a narrower

they must match.

Probably not.
You've at least got to look up the pairs.
I don't know how rugged the bus is electrically, I've never looked up
the spec, especially if 10m cables might be marginal.

I looked around Homebase and B&Q - all I could find was a large (too
large) plastic duct that was really meant for air flow to a bathroom
fan, and normal surface trunking (the plastic sort with a snap on
cover)

Neither seem to be appropriate. Anyone know a conduit for the
following specs:

1) Can be chased INTO the wall (i.e. not surface mounted)
2) Can be covered by plaster or whatever after (not sure if there are
issues adhering to plastic)
3)Is large enough for two DVI cables including the plug (about 4cm
wide by 1.5 deep)
4) Most importantly, where can I buy it!
5) As an aside - what's the difference between conduit, duct, and
trunking?

Thanks

That'll do, stick that in the wall, it saves cutting the plugs off
too.

5) As an aside - what's the difference between conduit, duct, and

In loose general terms,
Conduit is the round tube used with singles cables.
Duct is a duct, could be a small 2" duct or a huge underground duct
that trucks can drive through, depends on the context.
Trunking is a two part cable management device, one part fixed to a
surface, the other used as a lid.

Thanks for the suggestion - thing is, they are very complex plug - DVI
plugs, so wouldn't want to cut them off anyway. Also, I'd like the
channel/conduit to be wide enough for the plug anyway, so that I can
replace them later if necessary (very expensive stuff).

So my question sort of still stands - where can I get an conduit wide
enough for a DVI plug (about 40mm), that will chase into a wall, and
what should I use to fill and cover the hole?

Thanks

For that size, you'd be into steel trunking. 2 X 2 or 3 x 3 (inches)

See:-

www.tlc-direct.co.uk

But what effect you'd have on the integrity of a wall by chasing it in,
I'm not sure. It will depend on the wall.

If the wall on which the plasma is to be mounted fortuitously backs onto
fitted wardrobes or similar in the room behind, it might be feasable to run
the vertical on the other side of the wall and then bring the cable
horizontally through the wall behind the plasma.

Otherwise I would suggest some expanded metal mesh across the trunking, to
give the wet plaster something to key into.

Think you're into waste pipe territory there. You'll need an extremely
deep chase though.
Might be worth nipping down your nearest electrical wholesalers, you
can get trunking about 25mm deep by varying widths upto 100-150mm, if
you can get a length it would save chasing so deep.

As a start, some stuff from the MK catalogue.

25mm x 50mm mini trunking. Cat No. YT/6
50mm conduit. Cat No. HIP/6 BLK
25mm x 100mm trunking. Cat No. NBT/3
