- Running a cable under floorboards
I’ve used a couple of techniques in the past. If it’s a straight run then use a long piece of wire. I’ve used in the past a length of welding rid. About 2mm thick, so it’s stiff. Tape the wire to one end and thread it through.
I used a technique the other night to route cable over noggins in my ceiling using a length of 15mm plastic tube over a run tat was about 6 feet. I threaded the pipe over the top of the noggins then threaded the cable (cat6 network cable) through the pipe then withdrew the pipe.Posted 3 years ago
Tent poles are a bad idea, you’ll no doubt fail on your first attempt to push through, then they’ll all come apart and get jammed under the boards when you try to pull them back. I worked with a sparky for a few years on and off, we never had a proper set of rods, just used lengths of pvc conduit or trunking lid.Posted 3 years ago
This assumes you’re running parrallel to the joists, or there’s space below them.oliverd1981Member
If I wasn’t fussy about the floor boards I’d use a hole saw to cut a big enough hole at both ends of the run to get my hand through and then use any of the methods mentioned above, to run the cable (and a draw wire!)Posted 3 years ago
You can keep the disc of floor board from the hole saw and using this and a couple of bits of timber underneath the floor to “make good” the hole.
I’m sure there’s a knack to this but I can’t figure it out.
I want to run a coax cable from the Virgin box on the wall to the other side of the living room.
Problem is, there’s a wood burning stove in the way so I can’t run it the most direct route along the wall.
The floor is raised wooden boards and the wood burning stove is up on a brick pedestal so to me the obvious thing is to drill a small hole in the floorboards by the wall box, another one on the other side of the room and somehow run the cable under the floorboards.
Go on then, how do I do it? It’s not far, about 5 metres.Posted 3 years ago
Don’t take the edge boards up, come away from the walls where the cable will come through by about .5m and take up a section of board there between two joists. Just enough so you can still reach under to get the cable up at the egdge. It’s much easier to work with your arm under the floor if you’re not squashed up against the wall, and reduces the run under the boards that you need to thread by a meter.Posted 3 years ago
DON’T Cut to the side of the joist !!!Posted 3 years ago
you need to cut across the floorboard on a line the runs down the middle of a joist. The boards either end that you’re not lifting will still be sat on half the joist. The section you lift will then go back down and sit on the remaining halves of the two joists.Yet1manMember
I had this exact issue a few years ago when wanting to run cables for rear surround speakers. I cut two small sections out of the floor boards (one at each end of the room) and used a big sturdy tape measure, extended it across under the floor boards, attached a piece of string and let the spring inside the tape measure pull it back across, I then used the string to pull the speakers cables across. Hey Presto !!Posted 3 years agobearnecessitiesSubscriber
Drill outside.Posted 3 years ago
Take co-ax up front wall and feed through guttering.
Attach cable to a drone and fly over the house.
Feed back through guttering on other side and drop cable to ground (attaching a mouse will help).
Drill from outside to in, blowing out about a m2 of plaster.
Force mouse through the hole. (Any remaining mouse will seal the gap).
With such a large void under joists you run a reasonable chance of being able to just lift the boards at one end and fish the cable out.
Push as much coax as you can down the hole at one end and then get a long pole or similar with a bit of flex in it – I used to have a long telescopic fisherman’s pole thing – and bodge a hook on the end.Posted 3 years ago
The reason for pushing loads of cable down the hole is, it’ll form loops on the ground and make it much easier to fish out.
No access point. When we moved in I removed all the carpets because they smelled of wee, no obvious access.
The stove is sat on a huge piece of slate we put in which butts up against the wall, the cable would have to run over that so even if we run it behind the stove, it’ll look shit.
The coax carries virgin’s special signal from their box to the tivo box. I doubt I could find a wireless setup that would transmit that and I’m not transmitting HDMI across the room. I want the TIVO box under the telly.
Neighbours house on the other side of the wall.
Cut along top of joist, noted. Buy expensive and very specific power tool I’ll never use again, noted. 😉
Thanks everyone one. Love you. /grinds hips.Posted 3 years ago
