Les1952 Posted February 28, 2019 Share Posted February 28, 2019 (edited) The main problem I have found with Neodymium magnets is that after a little while I find that the train seems not to have uncoupled but that there is a longer gap between the pair of vehicles I've been trying to uncouple than the rest of the train. Investigation invariably has shown that the neodymium magnet is holding the two vehicles together by the coupler tail having been uprooted. It doesn't seem to matter what type of adhesive I use, after a while the result is the same- the adhesive deteriorates with time and the culmination of the forces of uncoupling, small though these seem individually. Note I have used Superglue, UHU, araldite and even gorilla glue and all degrade with time and use. I've now reverted to using the Dapol magnets, which I can see clearly but punters at Sileby show the other week seemed not to be able to find even when looking for them. Les PS- I have experienced similar problems with Kadee couplers and neodymium magnets, reverting to Kadee magnets here as well.

Bernd60 Posted January 27, 2022 Share Posted January 27, 2022 allthough this thread is a bit outdated, I want to show you my testresults with magnets for the Dapol couplers. 1. I had best results with decoupling and pre-decoupling when positioning both magnets outside the track 2. pre-decoupling is possible only if the extension is wide such that the coupler does not lock if the wagon is pushed away. Therefor you will not succseed if the magnets are positioned inside the track. 3. the magnets can be well covered with ballast (last pic) Regards Bernd from Germany www.bernd-koe.de 5 Link to post Share on other sites More sharing options...
Bernd60 Posted January 27, 2022 Share Posted January 27, 2022 forgot to say, the cube magnets are 5 x 5 mm in size. 1 Link to post Share on other sites More sharing options...
woodenhead Posted May 2, 2022 Share Posted May 2, 2022 @Karhedron Thank goodness this thread is getting some of it's imagery back and especially your magnet images. I purchased some easi shunts and 3mm x 3mm magnets but could I get them to work. On Youtube I saw someone with eight magnets per installation and I was getting to the point of throwing it all in for the Dapol magnets. However, I've tested using your method and got a GUV and Southern CCT operating on a test track. A Farish Mk1 CCT had too much slack in the coupling housing that it was not firing every time though, so I need to pick the right items to retrofit with easishunts. The key appears to be not putting them too far into the baseboard, they need to remain proud. 1 Link to post Share on other sites More sharing options...

RMweb Premium Crepello Posted May 6, 2022 RMweb Premium Share Posted May 6, 2022 A lot of time seems to be spent on experimentation with magnets other than the Dapol ones. Can I remind you that the latter, cut in half, glued between removed sleepers (between rails) and covered with ballast are discreet and problem-free. 2 1 Link to post Share on other sites More sharing options...
bluedepot Posted May 6, 2022 Share Posted May 6, 2022 agree with crepello i played around but in the end it was less hassle to just get Dapol magnets and cut them in half tim 1 1 Link to post Share on other sites More sharing options...
Lacathedrale Posted September 13, 2022 Share Posted September 13, 2022 Sorry for the thread necromancy - these couplings have been renamed Easi-Fit, right? Does anyone have a rule of thumb on what length arm is required for a typical terminus-to-fy shelf layout (as opposed to a roundy-round on a coffee table? At £25/pack I'm reluctant to roll the dice! My stock is almost all modern Graham Farish and Dapol. Link to post Share on other sites More sharing options...
RMweb Premium Steadfast Posted September 13, 2022 RMweb Premium Share Posted September 13, 2022 It really is difficult to comment to precisely @Lacathedrale, because a lot can depend on how far forward the NEM pocket is located relative to the buffers.

Lacathedrale Posted September 13, 2022 Share Posted September 13, 2022 Thanks Jo - primarily I'm looking at Farish Mk1 and NPCS if that helps at all? I guess I could buy one of each! Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted September 13, 2022 RMweb Gold Share Posted September 13, 2022 I have used the shorter Dapol couplings in the Farish mk 1's. They do go round 11.5 inch radius curves on my layout. You will probably have to file down the bottom of the buffer beam aswell IIRC. The coach that goes next to a loco may require a mdeium length coupler but its a whils since I fitted mine and havent got easy access to them at present.

csiedmo Posted September 13, 2022 Share Posted September 13, 2022 The original version that used to be supplied with new locos is was what is now called the medium. That worked fine in terms of going around the first radius corners of my test track, so in your context you’re unlikely to require the long ones. Perhaps the best solution is to get one pair of short and one pair of medium and experiment with combinations? Link to post Share on other sites More sharing options...

My stock is almost all modern Graham Farish and Dapol. That price seems high. Are you just considering the magnetic type? You’ll find the plain Dapol Nemcoups quite a bit cheaper, if you’re not doing a lot of shunting. Link to post Share on other sites More sharing options...

This worked fine with code 55 but not with code 80, so it may not work in a larger scale. I suggest that it's worth experimenting with a test piece. The density and type of ballast might well affect the outcome too. 2 Link to post Share on other sites More sharing options...

Andy_C Posted October 27, 2023 Share Posted October 27, 2023 Tried a Dapol magnet under the code 55. 0.75mm of plasticard under the magnet, so it was sat right under the sleepers. Worked ok, so I’m implementing that option. For the sake of a few quid, I’m not cutting mine in 1/2. 1 1 Link to post Share on other sites More sharing options...
Les1952 Posted November 1, 2023 Share Posted November 1, 2023 One thing worth mentioning with these couplers. They work brilliantly on TT:120 stock- the stronger centring springs on the kinematic couplings in the larger scale mean that when the trip pin is pulled off to one side by the magnet the jaws open rather than the whole coupler being pulled sideways. In addition the greater weight of TT stock means that when pulling the couplers stay coupled, and when propelling the wagons don't tend to shuffle relative to one another, meaning that if the jaws are actually apart (still difficult to achieve) they stay apart until the shunt has finished...

bluedepot Posted November 5, 2023 Share Posted November 5, 2023 I put my magnets about level with the sleepers or maybe v slightly lower. they are situated in slots in the cork underlay. the sleepers are removed in the centre over the magnets. I find half magnets fine but I need to put markers showing where to stop! you need to be precise! tim 2 Link to post Share on other sites More sharing options...
Andy_C Posted November 6, 2023 Share Posted November 6, 2023 (edited) I've settled on placing the magnets directly below the code 55 track sleepers, so it's touching said sleepers. I've used 0.75mm plasticard to ensure this stays constant, and have also marked the area where the magnet is with a couple of strategically placed yellow dots (this will become less conspicuous once weathered). I've also used full magnets. Edited November 6, 2023 by Andy_C 2 Link to post Share on other sites More sharing options...

csiedmo Posted December 16, 2023 Share Posted December 16, 2023 (edited) I’ve been watching Rapido Railcrew electromagnetic uncouplers being installed on Perth South, and wondered whether they would work with the Dapol Easi-Shunt couplings? They’re labeled as HO but I don’t see why scale matters. I guess it more a question of whether they would actuate the Easi-Shunts in the correct plane and to the correct degree, but I can’t think why they wouldn’t. Surely it’s just a magnet with an off switch? Edited December 16, 2023 by csiedmo 2 Link to post Share on other sites More sharing options...
