  1. 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
  2. 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 the cabin to run on. The most time consuming bit was the outer 2 panels and the end details as this required the stiffening plate work. It still requires quite a lot of detailing such as walkways, ladders, piping etc, but these will be added once it's working. Simon
  3. 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. Some copper clad strip is used to mount the rail, as this will be insulated on both sides as it's used to get power to the cabin. Next to make will be the cabin. Simon
  4. 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 contact area, I did try round but it tended to wobbly a bit. The unloading area is designed to hold four wagons so these need to be reliable, which so far is looking good. The biggest problem is the design of the tipping linkage on the wagons which tends to be a bit tight, but by stripping the wagons down and freeing up the linkage it dramatically improves the performance. I've tried some crushed stone ballast in the ore bin and tippers and it runs more freely so it's probably the way forward. Time now to build the other three sets. Simon
  5. 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
  6. 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
  7. 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
  8. 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
  9. 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
  10. 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 done with cellulose paints. My loco building business brought a few surprises over the years, with repairs to a couple of his locos and the purchase of Hobbyhorse Developments lost wax casting business , which used in its early days a lot of his fitting details as patterns. One must not forget that Norris was also building to similar standards at the time, and between them gave us a wonderful collection of outstanding locos, and not forgetting Tony Reynalds who is continuing the legacy. I will dig out some of the fittings and other bits a post them. Simon
  11. 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
  12. The next stage in the construction is to complete all the bits inside the frames, so starting with the valve gear and valve chests. Completing these entailed quite a bit of work over several months, but very enjoyable when done in stages especially when machining the very small dummy bolts and nuts. That's another job ticked off, texted the springs. Simon
  13. Just posted a Daren't updated in the Scratch build thread. Starting on some Foamex walling. Simon
  14. That reminds me I must do an update on the Darent builds. Simon
  15. I've put a few of the Millard kits together and your correct about the sparse detail, but go together well and adding the details from other sources or making them isn't a problem I've found. Simon
