How can I get cable through this wall?
Want to install some extra points in our office....the switch cab is in the next room, trunking already runs the whole way, very easy 10m run.
Except...it goes through a wall. An electrician drilled the holes and put the existing cables through a while ago, and while I could get them back, as the holes are already there and I only need to get 3 more cables through, I wanted to do it myself.
The problem is that the wall at it's core is solid brick, then either side is plasterboard, then to make matters worse there is an additional ledge on the lower part of the wall, so the thickness is getting on for 30cm. Also, although holes are cut, they arent very well lined up through the different parts. On both sides and presumably the middle, there is plenty of space for more cables.
Allow my crude diagram to illustrate the wall.
(ok I can't even get a picture to show up now, not having a good day!)
My usual method is a wire coat hanger, unwound. I poke one end into some CAT5, then poke it through and pull it the other side. The problem here is that because I can't see which part of the hole it is going through, it is getting too tight and I end up pulling the hanger through without the cable!
What other tools techniques could I use to get this bloody cable through?
