paulears Posted April 25, 2017 Share Posted April 25, 2017 I have to feed two HDMI cables through a very small gap - the plug end of the moulded cables is too big for the gap, even if I shave off the corners. The cable on my moulded leads will be fine. My plan is to cut the cable, thread it through then repair it. Any tips or no-go areas. It doesn't have to be pretty, just functional. Once in, they won't move. Link to comment Share on other sites More sharing options...
jmdh Posted April 25, 2017 Share Posted April 25, 2017 My vague recollection is that the tolerances are pretty small, so a manual rejoining job may be tricky. A quick google throws up https://www.houselogix.com/shop/hdmi-repair-kit which may make things easier? There are some DIY videos on youtube too.

Dj Dunc Posted April 25, 2017 Share Posted April 25, 2017 I assume converting to Cat5 and then making up some cable in situ is out of the equation financially? Link to comment Share on other sites More sharing options...

mac.calder Posted April 25, 2017 Share Posted April 25, 2017 Have a look at Celerity. It is a (relatively) cost effective cable designed for running down conduit and chasing into walls. It is an HDMI over fibre product but without the exposed fibre optics. Or go with a cat based solution. I have seen field-terminatable HDMI connectors before - but they required special crimping tools AND when terminated correctly were good for 1080p @ 12m (according to manufacturers spec). The installer however said he would not do it for anything longer than 8m in practice on one that looked really good. The connector was modular with a little 'sled' that slid down the twisted cores to ensure minimal untwisting. A good shield connection was the other crucial part. So I guess if I was to be splitting and re-joining mid cable - ensure you maintian the twists and also make sure you end up wrapping with some foil tape or similar to reshield.

jamessmith2k Posted April 25, 2017 Share Posted April 25, 2017 Can you not make the small gap slightly bigger?? may be cheapest and "best" option long term? Link to comment Share on other sites More sharing options...
paulears Posted April 26, 2017 Author Share Posted April 26, 2017 The gap is literally a gap - between two layers of brickwork - about 8mm, as I can feed a bit of mic cable through it, but not connectors. Appearance isn't that critical - so maybe chopping and then putting a new connector on might be the way to go - I found some HDMI sockets with solder pad terminations. I was kind of thinking about simply stripping back 150mm or so, and then resoldering each conductor staggered over the distance, then wrapping a new screen. End to end, between equipment in the two rooms would be no more than a couple of metres max, I think - say 3 to include a bit of wiggle room in the cabling. Is this a non-starter?

timsabre Posted April 26, 2017 Share Posted April 26, 2017 At 3m total length you should be ok, especially if you are careful to preserve as much of the twist in the cores as possible. But some equipment is really picky about what it will accept, and some generates flaky HDMI to start with, so the success of your plan will probably depend on what you're plugging between.

paulears Posted April 26, 2017 Author Share Posted April 26, 2017 I'll give it a shot Tim - my second fallback will be mini HDMI - there is a chance that if I shave down the connector, it might just fit, then an adaptor back to full size - cheers.

gyro_gearloose Posted April 26, 2017 Share Posted April 26, 2017 Is enlarging the hole completely out of the question? Even if the hole is only big enough to for a mini hdmi, or bit of cat5? I've got a 20mm masonry bit if you want to borrow it. Link to comment Share on other sites More sharing options...
pjb304 Posted April 26, 2017 Share Posted April 26, 2017 Don't forget there's also micro HDMI, which is about the size of a micro USB connector, so might require less shaving. Link to comment Share on other sites More sharing options...
paulears Posted April 26, 2017 Author Share Posted April 26, 2017 20mm bit - but at least 600mm long? That could be good? I also didn't know about the micro HDMI. Looks like I do have a few options - cheers guys. Link to comment Share on other sites More sharing options...
bruce Posted April 26, 2017 Share Posted April 26, 2017 A 20x1000mm sds bit is 17 pounds in screwfix. I'm sure I've seen them cheaper in a local budget tool shop Link to comment Share on other sites More sharing options...
Simon Lewis Posted April 26, 2017 Share Posted April 26, 2017 Think they're charging £33 for the 600mm 22mm dia SDS bit, but the 600mm 10mm dia bit is indeed £17 and is probably more useful long term as a cable routing device!Paul - if you drill through with the 600mm, you can enlarge from each side with a more standard 20mm if you have that?

paulears Posted April 27, 2017 Author Share Posted April 27, 2017 maybe multiple 10mm is the way to go, because I cannot get to the other end with a drill, there's not enough space in the cavity at that end - essentially I have to go in from both ends, and meet in a small one brick 'hole'. I think I can fish from one side of the cavity to the other, but it's awkward. Link to comment Share on other sites More sharing options...
