  1. I’ve been putting off doing the reversers as it has required quite a bit of effort with the parts required for them. First on the list was to do a drawing to produce the patterns for the links, arms, bases and handles, then cut these on the pantograph. With these most of the bits have been silver soldered, as this provides invisible joints once cleaned up and stronger. Not fitted them yet as I’m doing everything that’s required inside the frames to be completed, then stripe down the frames and fit them everything in one go, anyway thats another bit ticked off the list.

  2. I've been scratching my head for a while about making the hand rail stanchions, luckily Darent doesn't have many only for the safety valves. So after sourcing some brass balls of the correct diameter, the fun started. First a jig was made to hold the ball and the rod, the balls needed drilling twice, once to get the hole for the rod and then again when the rod was soldered on. Before drilling the balls needed softening as those supplied were in hard condition, the blow torch sorted that out. A small washer was turned and the end of the bars threaded, then attached to the models. I di
  3. We developed that system for it's simplicity, my friend who was an electrical engineer did the article and we fitted the rest of the locos on our exhibition layout Tewksbury with them. We never had any running problems after that. Simon
  4. Looking around at the trade offerings for suitable small yard office type buildings I decided that around the £50 mark each was rather expensive, so other than some doors, windows and chimneys which I already had I spent this week putting these together. These will be used as the reception office for the Yard masters that also contain the ground frames. The walls are made from Foamex scribed with suitable brick work and coloured with a mixture of rattle cans, acrylics and coloured pencils. Simon
  5. The very toxic election that's going on at the moment sums up today's mentality, both sides have a lot to answer. I did back the for change group but have come to the conclusion that it's probably better not to bother with it. The problems will never go away as big organisations forget what the core issues are all about, it's supposed to be a pleasant hobby that everyone can injoy without criticism. Simon
  6. I've been cracking on with the carriage for the Gantry Crane, at times it seams like building the Forth Bridge but it is enjoyable. It is constructed of 4 panels with the central 2 made up of T beams top and bottom, and the outer 2 plan angle. The cost of brass T section was eye watering so I made them my self, with all the other off the shelf from a well known supplier. Each panel was assembled in a jig, this ensures everything is square. The wheels are insulated on both ends again, this well be used to supply power to the control cabin, plus the rails on the top is also insulated for th
  7. Some heavy engineering now, which is for the Gantry Crane. We've got one on The Yard layout which I'm sure many of you have seen. This one is a bit smaller and the base is of different construction, being precast concrete. The upper carriage will be similar to The Yard, and the cabin will gauged the same to act as a spare should it be needed. I had some brass T section and square in stock that looks very similar in size to the prototype, and after a couple of hours on the mill the basic structure was complete, I'm using pins at the moment to hold it together but it will be glued.
  8. With the Ore Bin working, the last couple of days I've been working up the mechanical bits for unloading the ore tippers. The design needs to hold the chassis to stop it tipping and then move the body enough to discharge the ore, and also allow clearance for the loco and wagons to move through the unloading bay and it needs to fit into a fairly small space. So the two rams would need quite a bit of travel, the body ram is round and I've speeded up the movement which does clear most of the ore, ( I'm using woodlands scenic ballast at the moment.) the chassis ram is square as this gives better c
  9. After doing some stuff on the ON30 layout it's back to Darent, with the springs. Normally I not the greatest fan of making springs, as it was part of the day job a while ago, but these I have enjoyed. Started by making the assembly jig and new anvil for the rivet punch to enable the brass angle to be riveted. All 8 springs are the same, the only difference is in the angle brackets. That's another job ticked off for the bits inside the frames, next the derail protection bars. Simon
  10. With the Ore bin working well I've put that aside, and made a start on the chalk walling and some of the various building around the Northfleet Quarry. The walls are from Woodland scenic moulds, and I break them into smaller pieces to give a better random effect. So far buildings wise I've started on the yard office, fuel tank, water tower, bridge and loco shed, still lots of detailing required on them but I can see how these fit into the scene before finalising the positions. Simon
  11. Completed fitting all the servos, operating wires and chains, after some testing I found that the arm that opens the doors wasn't man enough for the job, so made some new ones in brass, this is much better and works well. I'm using some Woodland Scenic ballast at the moment, it flows quite well. Simon
  12. These are a few bits that I've dig out. The cost of the fitting are quite expensive, have a look at the cost of the LMS cab fittings, for 1973 that was a lot of money. Simon
  13. Welcome to posting. The frog does have a separately feed via the point motor. The reason why the switch blade have a power feed is it's only relies on two bent down tabs to transfer the power. The outside rails also have power feed, it's very much belt and braces but over the years this system has worked faultlessly. Simon
  14. Stan was very much an inspiration to me, his quality of workmanship was outstanding. One thing it certainly did for me was to make me want to try and produce models that stand out in details and quality of finish. I've been very privileged over the years to see a great many of his models and work bench that's been preserved at close quarters, and talk to a few who new him. The book does give an insight into his way of working with what information was available and some good photos of the models, unfortunately his was quite secretive with a lot of his methods especially the painting, which was
  15. This is probably the easiest solution, easy to adjust. I'm feeding in 12 vdc, this is to power some small motors, bought 5 for £4.5. Although it states 3v it goes down to almost .5 volt. https://www.ebay.co.uk/itm/Super-Mini-3A-DC-DC-Step-Down-Buck-Converter-3V-5V-16V-UK-Stock-From-0-65p/254490668546?hash=item3b40d36e02:m:mXspK3qZ0Zmk8BnjWvIQ7Rg Simon
