N15class Posted March 23, 2012 Share Posted March 23, 2012 Thanks for that Jon. I will have to look into it they look easier to fit than relays. Link to post Share on other sites More sharing options...
Jon Fitness Posted March 23, 2012 Author Share Posted March 23, 2012 Thanks for that Jon. I will have to look into it they look easier to fit than relays. Smaller cheaper easier to come by and more controllable. Much less stress on your signal linkages as well. JF Link to post Share on other sites More sharing options...
Jon Fitness Posted March 23, 2012 Author Share Posted March 23, 2012 Many thanks for that Mike. The one I have fitted is purely for a movement in the wrong direction along a main line. The usual simplified meaning for a shunt signal to a driver (as I understand it) is "proceed as far as the line is clear; be prepared to stop short of any obstruction" JF 1 Link to post Share on other sites More sharing options...
RMweb Gold Steve Hewitt Posted March 26, 2012 RMweb Gold Share Posted March 26, 2012 Hi Steve, If I can fight my way through the massed hoards round the now legendary Lime Street I'll certainly have a chat. As far as learning from others, many thanks for introducing me to servo operation! You've probably forgotten more than I've learnt regarding signal building!! I still haven't mastered soldering built up ladders yet................ JF Hi Jon, Sorry we only had time for few words at Ally Pally. Never been on such a busy exhibit before. As to "solder-up" ladders - I've stopped a while ago. I use the best (finest) flat etches I can find, preferably with half etched rungs. I then solder fine Nickel Silver wire up the rear of the ladder stiles to give strength and depth. I use .3mm wire on 4mm models and .6mm or .7mm wire on 7mm scale ones. Polish up the edges with a fine file or emery board to finish them off. Hope to have a longer chat at a future show somewhere.... Steve. Link to post Share on other sites More sharing options...

Lime Street looked superb and seemed to be running well too! I use D&S ladders as they do scale 30' lengths and they're nicely proportioned. Fairly fine without being too weak. I used the trick of soldering wire down the stiles when I was building signals for the garden railway as it made them strong enough to handle a bird landing and taking off again! I'll have to have another go and take your advice about filing the sides to get a flat edge. Cheers JF Link to post Share on other sites More sharing options...
Jon Fitness Posted March 31, 2012 Author Share Posted March 31, 2012 (edited) Right. At this stage I now have the handrails and stanchions (0.6mm) on and the ladders fitted. Just the ladder hoops on the 2 larger dolls to do then off to the paintshops.Should be ready to plant in a few days.JF Edited June 3, 2015 by Jon Fitness 3 Link to post Share on other sites More sharing options...
RMweb Gold The Stationmaster Posted March 31, 2012 RMweb Gold Share Posted March 31, 2012 Very nice Jon - I hope it might appear in WR (as opposed to GWR) colours as I feel the later version suited modern gantries and dolls a lot better. Link to post Share on other sites More sharing options...

If I had my way it would be silver/black and weathered down but my customer wants it pristine with white dolls. I think the main posts will be grey though.

Jon Fitness Posted March 31, 2012 Author Share Posted March 31, 2012 Grey - hints of an LMR takeover there methinks. It'll look like silver from a distance, and all the other signals I've done for him (and there's quite few) are per his request, black and white.

Jon Fitness Posted March 31, 2012 Author Share Posted March 31, 2012 (edited) All painted and seems to have freed off reasonably well after 3 or 4 coats. A spot of oil here and there should smooth everything up.If I can organise it, and anyone wants to see it I'll post up a test video with lights lit and signals going down and up & stuff.

Jon Fitness Posted April 1, 2012 Author Share Posted April 1, 2012 (edited) Here's a bit of a video of the gantry on test.

RMweb Gold The Stationmaster Posted April 2, 2012 RMweb Gold Share Posted April 2, 2012 Works very nicely - definitely had a good Linesman adjusting those arms.

RMweb Gold Steve Hewitt Posted April 2, 2012 RMweb Gold Share Posted April 2, 2012 Jon, Very nice! How do you drive five arms / servos with a Servo4 board? Is that unconnected lead in the background the answer? Steve. Link to post Share on other sites More sharing options...
Jon Fitness Posted April 3, 2012 Author Share Posted April 3, 2012 Jon, Very nice! How do you drive five arms / servos with a Servo4 board? Is that unconnected lead in the background the answer? Steve. Spotted! It's just a test lash up to check everything works before delivery. The customer is supplying his own DCC powered MERG boards (I think they'll operate 8 servos!) Fortunately I had managed to set the servos up so that when I swapped one servo lead out for the 5th one the stroke was exactly the same. The only adjustment needed was one of the back blinds was a bit close to a lamp case and had to be tweeked out a bit. Cheers JF Link to post Share on other sites More sharing options...

Jon Fitness Posted April 7, 2012 Author Share Posted April 7, 2012 (edited) Honestly, although I still have 3 more to build, this is deffo the last GW signal for now!Wooden post early pattern stop&distant with (because I forgot it at the time...) an additional c/o arm on a little scratchbuilt bracket.All worked with the usual servos and LED lit.Used my usual trim tape to secure the servos in a stack underneath but just to be sure I soldered a strap of brass around the stack and to the base as well.Now where's my tray of U/Q bits gone?.......
