RMweb Gold Captain Kernow Posted November 28, 2020 RMweb Gold Share Posted November 28, 2020 I have used Seep point motors (solenoids) on handbuilt points for years (both copper clad and plastic sleepers), which use a copperclad sleeper as the basis for the tie bar (and a thinned-down copper clad sleeper at that, so less wide than an ordinary sleeper), these work fine, provided you have a decent soldered joint between the tie bar and the point blade. I then went on to using Tortoise point motors on a later layout, with both copper clad and plastic sleepered points, albeit using under-board operational tiebars and just cosmetic ones on top. My latest layout uses Cobalts, again with thinned down copper clad sleepers. What I like about the Seep, Tortoise and Cobalt motors is the ability to switch the polarity as well. Only one of the Cobalts has given any trouble, in that it makes a repeated 'clicking' noise when the point blades are thrown in one direction. I should really substitute it for the spare that I have, but the problem is easily solved, in that the points are actuated by switches with a 'centre off' position on the control panel, so to stop the clicking, I just put the switch to 'centre off', when the point blades have moved across. This does not affect the electrical polarity etc. 2 1 Link to post Share on other sites More sharing options...
down the sdjr Posted November 28, 2020 Author Share Posted November 28, 2020 (edited) I must admit, I have bought a DCC cobalt ip analogue to try on a few points before I decide any further action. I like that you can wire them in with switches and a power supply, no need for a driver or control unit. DC.

This does not affect the electrical polarity etc. It's the gears slipping inside the point motor. It was a problem on an early batch, owing to excessive clearance in the housing. I would send it back under the lifetime guarantee. 1 2 Link to post Share on other sites More sharing options...
