Not exactly a Tech issue but I could use some guidance. Last year I bought some couplings from the Settle shop. Lockdown means I have just started to install them. The uncouplers state  "do not use contact adhesive". Other options I have in stock seem to give poor adhesion. What adhesive have other modellers used successfully to mount these magnet strips both on top of the sleepers for Code 100 and between the sleepers for Code 75?  Also if you are cutting away the sleepers for Code 75 does it make any difference if you install a Code 100 or a Code 83 uncoupler?
Many thanks.

Hi Roger. You can use any adhesive but you do need to be careful... Contact can creep and if even a tiny bit gets in the wrong place, its a disaster. It is also difficult to remove if anything fails, those are the reasons why Kadee don't recommend it.

Screws are, in reality, the #1 way to fix them. We sell a an M2 2mm screw which, as one of the small miracles of metric conversion is exactly the same as the "imperially measured" 2-56 screw recommended by Kadee.

If you want to do a totally "engineered" install, Imperial associated tool sizes are #51 bit and a 2-56 tap but that is expensive - so if you like, and take your time, just use a 1.7mm drill. The M2 screws will self-tap into a hole drilled with a 1.7mm drill bit (drill it by hand not with a dremel etc)

Hi Roger,
Despite the instructions, I have always used Evo-stick to mount the uncouplers. But, you do have to be very careful with alignment, as, as Ahjay says, they are difficult to move once the adhesive has grabbed.  

On the other issue, the key is the uncoupler's height compared to the rail head. Needs to be fairly precise, as if too high, the couplers will foul on it, and if too low, they will not be as effective.

Hello Roger, an interesting thread as I am planning to use Kadee 321 uncoupling magnets with Peco code 100 track.

Ahjay, in your reply to Roger, are you referring to fixing the couplings to the rolling stock or the uncoupling magnet to the track? 

With best wishes,

Dave

Thanks for clarifying Ahjay.

Thanks for the replies and sorry for the delay in reresponding but have been on grandfather duties for past few days. Will look at using evostick which would have been my natural choice. Click image for larger version - Name: 2020-04-06_15-53-14_751.jpg, Views: 16, Size: 309.19 KB

Several years ago i brought a CM X track cleaner tank wagon. Great piece of gear and if you fill it up with isoproponal ( rubbing alcohol) )it works a treat. I run OO British outline diesel locomotives and the problem i am having is to find a loco to tow it. I have plenty of locomotives more then capable of the task but due to the height difference between the kadee couplings on the tank and the height of the coupling when fitted to Bachmann / Hornby locos my towing range is limited. Is there a simple solution to the height difference

Use the correct Kadee in the locos - there is only one correct height for Kadee, and the CMX is at it. Kadee do offer couplers with NEM and couplers with dropped heads.

I actually fitted a buffer beam to mine with a hook and a three link coupling so I tow it around with that.
