Stephen Freeman Posted June 20, 2012 Share Posted June 20, 2012 Those of you have tried to use the MSE kit for GWR Ground Signals in 4mm scale, especially the small 1918 discs with bevelled edge, may have wondered how to make the things work. Actually making the discs move is not that difficult but getting the balance arm to move in connection is a little tricky. Here's how I do it: Making the disc move take a small strip of brass drill two small holes in it. The distance between the two holes should not be greater than that which would allow hole one to be in line with the centre of the disc and hole two to be just behind the edge of the disc, so that when fitted it cannot be seen from the front. The strip should then be trimmed to length. Solder the strip to a piece of wire which will be the centre drive rod for the disc. Then solder a small etched washer so as to space out the strip from the disc. Then solder to the disc so that the strip is in line with the strip on the front of the disc. The operating wire should attached to hole two and the disc installed. Making the balance arm move Tricky but simple, you just need to wrap the operating wire around the end of the lever. The operating wire will need some method of restraint, otherwise it will come off the lever. I used a small piece of wire soldered across the base to keep it in place. Photos (and possibly a video) In due course, lamp still to be added. Link to post Share on other sites More sharing options...
RMweb Gold RedgateModels Posted June 20, 2012 RMweb Gold Share Posted June 20, 2012 Good timing Stephen, I'm about to order some 7mm ones ...... Link to post Share on other sites More sharing options...
Stephen Freeman Posted June 20, 2012 Author Share Posted June 20, 2012 Good timing Stephen, I'm about to order some 7mm ones ...... Hi, Thanks - the 7mm ones present something of a lesser challenge as you get a whitemetal balance arm with holes in. Link to post Share on other sites More sharing options...
RMweb Premium figworthy Posted June 20, 2012 RMweb Premium Share Posted June 20, 2012 Thanks. Very helpful. I've got a couple that I've yet to build, so I can see myself coming back when I start. Adrian Link to post Share on other sites More sharing options...

I'm gonna need all the help I can get I've a fixed stop with secondary into headshunt for a start, never mind the ground signals, one of which will be a stack of two - I've only ever built one simple MSE signal before Link to post Share on other sites More sharing options...
Horsetan Posted June 20, 2012 Share Posted June 20, 2012 Are you the same bloke who produces those £4.99 signals for eBay? Just curious..... Link to post Share on other sites More sharing options...
Stephen Freeman Posted June 21, 2012 Author Share Posted June 21, 2012 I'm afraid I can't comment on that, as what I might or might not sell on Ebay or elsewhere might be construed as advertising. Link to post Share on other sites More sharing options...
RMweb Gold RedgateModels Posted June 21, 2012 RMweb Gold Share Posted June 21, 2012 But they are on eBay with a START PRICE of £4.99, BIN is £29.50. Just in case anyone fancied a nice hand built signal Link to post Share on other sites More sharing options...

RMweb Gold Happy Hippo Posted June 22, 2012 RMweb Gold Share Posted June 22, 2012 Stephen, Thank you for sharing this little gem of information. Although I only need to have one ground signal on my embryo railway, it is nice to be able to watch it work properly. Regards Richard Link to post Share on other sites More sharing options...
RMweb Gold Steve Hewitt Posted June 22, 2012 RMweb Gold Share Posted June 22, 2012 Hello Stephen, Did you see my topic on these signals over a year ago? see http://www.rmweb.co....ground-signals/ A little more fiddly than your "wire wrapped round the balance arm", but effectively the same principle. It does follow the prototype as seen in the photo posted as a reply. Steve. Link to post Share on other sites More sharing options...
Stephen Freeman Posted June 26, 2012 Author Share Posted June 26, 2012 Yes but the diameter of the 1918 discs is about half the size of those, which makes putting the drive rod directly into the disc not a good idea. Link to post Share on other sites More sharing options...
