RMweb Gold Stubby47 Posted February 22, 2020 Author RMweb Gold Share Posted February 22, 2020 Haven't tried yet Rob, but hoping it will be fine. I've read the remedial work done by others so it seems it could be made to be all right if necessary. Link to post Share on other sites More sharing options...
RMweb Gold Stubby47 Posted March 8, 2020 Author RMweb Gold Share Posted March 8, 2020 (edited) Actually in the garage working on the layout. 1st job, open up the left hand ground near the tunnel to give room for the cutting. 1st disaster- have cut through the feed wires to the track.

RMweb Gold Stubby47 Posted March 11, 2020 Author RMweb Gold Share Posted March 11, 2020 Today I have received a couple of MERG kits, one to replace the duff EzyPoints unit already on T-CATS, and one for a simple speed controller to form part of the control panel for The Circle. Might need to get the soldering iron out tonight... 3 Link to post Share on other sites More sharing options...
RMweb Gold Stubby47 Posted March 12, 2020 Author RMweb Gold Share Posted March 12, 2020 Soldering was achieved last evening, I now have a simple speed controller that can be attached to the control panel. I also found a DPDT switch and just need to adjust the wiring to utilise a 12vdc feed rather than the 16vac (unless I also purchase and make the 12vdc supply module). Having moved the layouts around in the garage, I can also make and add the fiddle stick / yard without this being clobbered by the opening overhead door. I need to remove the accumulated spare wood from behind the layout to enable the loop to be deployed, which hopefully will be the weekend. A quick replacement for the duff servo board with one I'd made previously and replacement of the main feed wires will then enable the layout to be fully tested. The final piece of track needs relaying, for some reason the ends of the rail have curled upwards where the isolating section is - it's done this twice on different pieces of rail, so I'm not sure of the reason (apart from probably my clumsiness). Then I'll need to add a baseplate for the town's buildings, which can then be made on the bench and added piecemeal. Painting and grassing of the front areas can also be done, I need to consider how to disguise the FY exit on the left. A row of terraced house backs was one option, but I'm not sure Nanpean (as I've modelled it) was that 'urban'. So, lots to do, but as the evenings are getting lighter and slightly warmer (so the paint & glue dries!) the rate of progress should improve.

RMweb Gold Stubby47 Posted March 13, 2020 Author RMweb Gold Share Posted March 13, 2020 With much more than a month to go, an idea has surfaced which is to use some of my existing buildings. For example I made a farm complex in the style of Allan Downes, which suitably altered will sit front left. I also have a model of a Leeds building named after Shortliner, which should fit along the back or on the right. A visit to the loft and a search through some boxes is required... 5 Link to post Share on other sites More sharing options...

RMweb Gold Stubby47 Posted March 14, 2020 Author RMweb Gold Share Posted March 14, 2020 This is the main control panel for T-CATS. Those observant among you will notice a new rotary switch and associated DPDT switch. These are to control The Circle. This is the circuit board attached to the aforementioned switches, which should be providing the ability to vary the output voltage from 1.2v to 10.75v. Currently it's providing between 0v and 1.2v. And I don't know why. 3 2 Link to post Share on other sites More sharing options...

RMweb Gold Stubby47 Posted March 14, 2020 Author RMweb Gold Share Posted March 14, 2020 Red is 12v, Purple is 0v. Brown are to the pot, green & brown are output to the DPDT. I've checked the orientation of the bigger capacitor and the diode, and checked there are no stray feeds across the copper tracks. The components match the photos and diagram in the instructions.

RMweb Gold Alister_G Posted March 14, 2020 RMweb Gold Share Posted March 14, 2020 I've downloaded the MERG diagram now, and it all looks OK. You have wired the pot with one wire to an outer pin, and one wire to the centre pin, haven't you? Al. 1 Link to post Share on other sites More sharing options...
