I got an MC36 remote a while back, I knew it was damaged but had forgotten about it until this evening. Ideally the remote needs opening up and the wires need shortening and reconnecting to the PCB inside. I can't handle fine soldering anymore, not that I have ever been much good at really fine pcb work. I wondered about using self amagamating tape wound tightly around the ferule and the first inch or so of the cable but it seems like a bit of a lashup on a nice instrument. Any suggestions for a decent repair. It works just fine but it won't last long like that and moisture could get into the MC36 itself via the cable. You get quite a bit of condensation at night.

How big is the plug on the end - could you use some heat shrink tubing?

Unfortunately it's an angled ten pin plug with integral locking nut. relatively bulky, I don't think any heat shrink would seal onto the cable outer which won't be any bigger than 6mm. I suppose I could build the cable up with some tape and then use heatshrink. 4X might do it, preferably with glue lined tube.

Another thought - if there is room inside the case, could the cable be pulled through to the good cover and fixed with a little silicone sealant?

Fresh back from using ot for the first time, it's wonderful, works like a dream. Made six minute exposures for the first time with digital. The D800 handles it perfectly. Thanks for the suggestion Chris, I will try splitting it tomorrow, see what's possible. I just taped it up for now. It's well worth restoring to good health.

Robert, Some suggestions for a repair. 1. You can get some large heat shrink cable, split it lengthwise and make sure it overlaps so it double covers the area. This will still leave you with a weak point at the entrance into the enclosure. You might be able to insert some heat shrink over the cable and into the housing. This would give you better physical strength. 2. Straighten out the cable then set it in potting compound or use Araldite around the area. You will need to make it so it does NOT flex as eventually the individual strands will break if they are subjected to multiple flexing. You might need to glue to the case to make for greater strength. 3. It might be possible to open the unit and pull the cable through into the enclosure then reseal the MC-36. You will need to check that these extra cables will fit inside. **** This would be my preferred solution. **** You can use some thick rubber solution or small amount of something like Evostik to seal it. 4. It might be possible to open the unit and resolder the cable after trimming but I would NOT suggest that as a first way forward unless you feel happy at soldering fine wires onto a very small circuitboard. I would have taken this on 10 years ago but my eyes are not as good at 1m from subject as before. Using reading glasses dont work, as well as eyes without glasses, as you need to change focus through the vertical plane which will result with you needing to bob your head around. DO NOT USE Silicone sealant as it contains acetic acid that will rot the circuitboard and cable.

Have opened up the MC-36, it's very well made, seems to be dated 7th Dec, 2016, or possibly 16th Dec, 2007? The American format back to front dates are a nuisance when they are showing dates which could be either. I'm not comfortable with the idea of re-soldering the connections, there are only 4 actual connections to the PCB but in a very tight space. The yellow, white and purple are the signal wires, the separate one behind, is the bonded earth/0V connection. I have tried with shrink wrap to get my largest piece over the plug but there is no chance, also I doubt if the shrinkage would be sufficient to grip the lead. There might be scope to cut back the sheath and make a coil of the spare conductor length above the main chip, not something I feel I could manage without damaging something. These devices are best part of £200, this was almost given to me. It works perfectly, I'm reluctant to do anything which may compromise that.

OK now I can see the innards. My no3 option is the best way IMHO. Will the cable pull through the gland into the enclosure. BTW. You can get MC-36 for £30 on ebay. There are also clones from Hahnel and other non-OEM suppliers that cost a similar price. https://www.ebay.co.uk/itm/Nikon-MC-36A-Mutil-Function-Remote-Shutter-Cord-Control-For-Select-Nikon-DSLRs/333151281199?hash=item4d915d202f:g:nxIAAOSwz7JZiZPd https://www.ebay.co.uk/itm/Cable-shutter-release-with-timer-Nikon-MC-36A-MC-36-MC-30-Remote-Shutter-Release/254259450438?hash=item3b330b5246:g:sPAAAOSw3nhc~hB6

Stop! Wait, if I cut the leads with plenty slack, then jointed the individual conductors well clear of the PCB and stagger the joints so there isn't a big bundle in one place, I think I could do it... Mmmmm... Will sit on it, no need for hasty action I might regret... Thanks for the suggestions JK, I agree some variation of your #3 is best, there isn't a lot of room in there. It works perfectly, am reluctant to spoil it. My eyes are similar, but probably more of a problem for something like this, my fine motor dexterity has never been good but rheumatics and arthritis make it very difficult to do fine work nowadays.
