This is it. I'm also worried about the possibility of breaking such a small coupling but without a doubt, it'll be when you can't get spares! I'd happily sacrifice some closeness for ease of getting apart. Link to post Share on other sites More sharing options...

From the video they look impressive if you don't need automatic uncoupling. I wonder whether they would be any good for a 1930s/ branch line with small 4-wheeled wagons? I will watch this thread with interest. I didn't wait I made my own for n gauge some months ago. The concept is great however I used four magnets per coupling pair. This is so I can reverse stock etc. Also when negotiating radius 1 curves/points there is a bit more give for unsprung coupling mounts on 4-wheeled stock. Edited June 22, 2020 by Std4mt Spelling.

Bino Posted June 23, 2020 Share Posted June 23, 2020 I received my couplings recently and I thought I'd share my thoughts. I intend running fixed formations on my layout so these seemed ideal. I hadn't had many issues with the TLC supplied with these but I liked the look of close coupled coaches. I ordered Close Coupling set for NEM pockets on my Bachmann Mark 1's and visually they are extremely good. However, I had a few issues.Some fitted well but some were very tight in the NEM pocket and I had to file out the pocket before they would fit. Others were not tight enough and resulted in the coaches uncoupling. Also, the rake made an odd clicking noise on the curves that I haven't been able to establish the cause of. In the attached photos it doesn't look like the buffers are touching on my 30inch curves. The noise may be the coupling rubbing against the underside of the coach frame as in this photo. The Bachmann TLC's avoid this contact with a drop in height rather than coming straight outward. Overall I think these are good and I want them to work for me but it seems I have had more issues than anyone else posting here. Link to post Share on other sites More sharing options...

RMweb Premium newbryford Posted June 23, 2020 RMweb Premium Share Posted June 23, 2020 Is it really the fault of the Hunt coupling that it's a problem on Bachmann Mk1s? I can never fathom out why Bachmann say the Mk1 has NEM pockets. The NEM-362 standard refers not only to the pocket, but the height (and distance from bufferbeam IIRC) of said pocket. What Bachmann should say is "We've used NEM pockets, but mounted them at a completely non-standard height which means that any NEM compliant coupling may/may not work. A similar issue arises when using NEM pocket compatible Kadees - such as the #17-20 range. Is there a possibility that the next person will come along and blame Hunt couplings for the reason why their Bachmann Mk1 won't couple to other coaches because the couplers are at different heights? I'm sure that as Westhill develop the range, they will come up with a suitable coupler for the vast majority of RTR stock I have no connection with Hunt/Westhill in any other way that as a satisfied customer of two version of their magnetic couplings - so far. 2 2 Link to post Share on other sites More sharing options...

Not at all - but like you, I think the Bachmann Mk1s have caused more issues by having non-standard height NEM pockets. (I've glued Kadees under the pockets before now!) A suggestion for Westhill - a height gauge. Two magnets of opposite polarity on a block that fits on the rails.

A similar issue arises when using NEM pocket compatible Kadees - such as the #17-20 range. Quite so and it occurs to me that if Bachmann actually did say that their Mk1s were fitted with NEM pockets, (it's possible they simply fitted them without such a description) would that not be an offence under the Consumer Protection/Trade Descriptions Act by them or any retailer who also described them as such? Kadee did go to considerable trouble to ensure that their #17-20 NEM362 "European Style" couplers were compatible with pockets that actually were to the NEM standard. They even allowed for the manufacturers who'd rather ignored the distance from the bufferbeam bit of the standard by supplying them in four lengths but the height of Kadees is fairly critical. Mind you, even in the USA, where the NMRA enforces its standards far more rigorously than MOROP ever could, Kadee still supplied couplers for draft boxes that had been set by their manufacturers at non-standard heights. The standard height for NEM boxes is set by the model standard but the standard draft box height set by the NMRA is based on that of the real thing.

Hi Bino The Standard Hunt does not fit well on the Bachmann Mk1 due to the NEM pocket height and the buffer beam. What I found works really well is the Hunt Pullman (stepped) Coach coupling. See my previous post https://www.rmweb.co.uk/community/index.php?/topic/151728-hunt-coupling-system/&do=findComment&comment=3959966 The resultant magnet height still lines up with Standard Hunt coupling. The ticking sound will either be the Hunt coupling rubbing on the buffer beam or the Bachmann Close Coupling mechanism having to work a bit more harder than it does with the original TLC. Rather than file the NEM pocket, just file a small chamfer on the ends of the coupling prong bobbles. You can also file the inside face of the two legs to allow them to close up more. For loose ones, a dab glue on the bobbles will hold them in place. Glue gun might also work as that can be picked off if the coupling needs to be pulled out. The issue is not so much the Hunt coupling but the variation in NEM pocket tolerances. The Hunt system is trying to cover all bases. I also tried the Keen system a while back on a rake of old coaches and whilst it worked well and gave good close coupling, I found it was noisy as the mechanism creaked works around corners and need oiling. I also found the two pin coupling fiddly to connect and it regularly fails on some of my gradient transition. For some of my other old coaches that do not have an auto close coupling systems, I might look at how you could “bash” the two systems together – Keen system for the close coupling part and Hunt for the easy coupling aspect.

LNERandBR Posted June 25, 2020 Share Posted June 25, 2020 (edited) So far I've had good experiences with a Hornby HST and Hornby Mk 2e coaches which don't have auto close coupling. The Hunt Close coupling has brought these close enough that the gaps between the coaches are acceptable but not so close that they clash on corners. With three levels of closeness now 'Standard', 'Close' and 'Untra Close' I think the Hunt couplings are getting very versatile. It's just a case of finding the correct length for the stock and curves you have. I haven't tried it yet, but I presume you could mix and match lengths. Have all the 'A' couplings in a rake 'Standard' length and all the 'B' couplings 'Close' for example to get a coupling length that's between the two. Would depend how 'fixed' you want your fixed sets to be! Edited June 25, 2020 by LNERandBR 1 Link to post Share on other sites More sharing options...
Jaggzuk Posted June 26, 2020 Share Posted June 26, 2020 (edited) Mix and match is possible. I have experimented with it on some wagons where the Standard version increased the buffer to buffer gap compared to existing TLC, but the Close type ended up being too close on my curves. So, I mixed a Standard and a Close. Based on my measurements (see post Hunt Coupling measurments ) the following NEM pocket separations can be achieved by mixing the three types. Approx. 1-3mm variation between each pairing. Personally, the 6.2mm difference between a pair of Standard or a pair of the Close types is too great. Standard is too long and the gap it creates is worse than TLC. Mix and match is also the only way to really solve the variations in NEM pocket position .

dmustu Posted June 27, 2020 Share Posted June 27, 2020 Hello All, I have recently fitted these couplings, and have generally found them pretty good. I can vouch for using the Pullman couplings on Bachmann mk1's, they work well. Only niggle really is that the A and B markings are on the wrong side, they face upwards, not downwards on these. I have swapped the couplings on Bachmann 108's with close couplers, I find the gap between the cars is about the same as the Bachmann couplings, so I think these would be ok with ultra close couplings instead, but I don't have any to test. I have also fitted the couplings to Hornby mk3's with the clip coupling, but ran into a problem with my blue/grey mk3's. This isn't down to the couplings, but rather the design of the bogie. My rake of blue/grey mk3's are from the first batch of the 'long' coaches Hornby released, probably over 15 years ago. the location of the 'pip' is further back from later release coaches. The bogie on the left is a later mk3, the one on the right from when the long mk3's were first released. Using standard length Hunt couplings are too close for all but the gentlest of curves. On my layout I use a standard coupled to a close coupling on the later mk3's with no problems, using standard length couplers on the early mk3's are extremely close, and cannot negotiate the curves on my layout without the corridor connectors fouling each other and derailing. Anyone know where to buy new bogies that match the one on the left in the picture from? Thanks. 1 Link to post Share on other sites More sharing options...
Jaggzuk Posted June 27, 2020 Share Posted June 27, 2020 (edited) Looks like the magnet polarity issue has NOW been resolved by Hunt Couplings with the introduction of the Hunt Couplings Elite for OO (27-06-20). https://www.westhillwagonworks.co.uk/couplings-new-c-2/hunt-couplings-elite-oo-gauge-new-c-21/ I saw this review video, which is a bit long winded, but it shows what the new Elite version with a square magnet looks like and how it works. So now it is possible, with this version, to swap any vehicle around and the couplings will still work! I think this is a very cleaver solution. I do not think they will be backwards compatible with the round versions as I am guessing the magnet polarity is now sideways rather than NSNS. This is my guess at how it works and it is why Nymondeum cube magnets can be staked. A good development I think. And taking the dimensions from the Shop website, we now get these NEM to NEM offset. Note that there is a new Intermediate version. Edited June 27, 2020 by Jaggzuk 2 1 Link to post Share on other sites More sharing options...

Andy Reichert Posted June 27, 2020 Share Posted June 27, 2020 Perhaps it's different here in the USA.

RMweb Gold Phatbob Posted June 27, 2020 RMweb Gold Share Posted June 27, 2020 The video I saw on bookFace posted by Westhill Wagon Works made it clear that the new elite (square) couplings work either way round with the original round ones, by virtue of the fact that they feature a much more powerful magnet.

Jaggzuk Posted June 27, 2020 Share Posted June 27, 2020 Thats is another nice demonstration video on Dean Park, cheers Phatbob. see here: Hunt Couplings Elite on Dean Park video Yes it does look like the Elite couplings can connect to the originals, but if you watch closely at 15:57, you see that the Elite on the loco kicks out sideways at it couples up so that the opposite magnet poles between the original and Elite are attracted. You can see this in the below screen grab. It will be interesting how this works in real life and the pull capacity, at least 5 TEA oil tanks!

Sir TophamHatt Posted June 27, 2020 Author Share Posted June 27, 2020 (edited) And while product development is great, I wonder if some nievety has been shown here. I'd say these newer couplings ( which have been produced by magnem couplings for some time now.) will annoy early adopters who will no doubt feel they have a now inferior product that, while is good at it's job, is perhaps now worthless. But then again, there is probably no "right time" to launch a new product. I guess both have their uses. For example in HST sets, the coaches are usually fixed in a certain way - using the non-elite couplings would make sure the set is always formed the right way. Same with DMUs a 2 coach DMU will always be fine, a 3-coach is usually formed with the middle coach in a particular way. I guess the elite could be good for wagons though.

The second far more functional magnet arrangement was obvious and already well understood and widely experimented with in the general hobby years ago. In fact it doesn't even require two separate magnets. So presumably there will be a third cost saving iteration in the not too distant future. The same method is already used for magnetic self coupling air lines and the auto couplers I showed earlier in this topic. Except my case I'm making an auto coupling and uncoupling system.
