  1. The weather was too nice to miss today so after a walk in Glenshee i managed an hour to get the wrappers and cylinder front cover. They are quite small cylinders being only 20" so it's a bit tight getting the wrappers soldered on with the piston tube and slidebars in there already. The rivets on the wrappers and the cover don't quite line up, i may file off those on the wrappers and add some transfer rivets during painting if they annoy me too much. I'm going to make a start on the footplate next. Dave
  2. The motion bracket is a fairly straightforward affair, some 1mm strip bent to shape, after a failure at my first attempt i found you just need to do the bends very gradually so as not to shear the brass, a few taps with a small jeweller's hammer to flatten it and then laminated both together. The cylinder side plates were cut out and drilled as a pair, and a 1.5 Dia i/d tube soldered between the two so that the crosshead has somewhere to slide, similarly the slide bars go through both ends to give some additional rigidity. A stretcher between the two will allow the assembly to be screwed to the frames and hence removeable. The tail end will be reduced later once the ends are fabricated and soldered on. The motion support is just loosely positioned here. Crossheads are from Andrew @ Wizard. I've cut 2 small notches into the main frames which will tilt the cylinder assembly at around 1: 40. The wrappers are next along with the distinctive cylinder ends. That should be fun. Dave
  3. Thanks Mike, the photos are always a useful resource for close in detail. On with the cylinders and motion bracket tomorrow. Dave
  4. Thanks, yes as i mentioned i have some etched coil springs somewhere but have added the leaf type for now, they're shown on the drawing in the post above.
  5. I cut the frames from 0.38 thick nickel silver sheet with a slitting disk, piercing saw and files to finish off. I omitted the springs as i'd a few from old Comet etches leftover that i could solder on rather than try to cut these out too. The springs were added, the rear driver shouldn't be a leaf spring but i believe they were coiled, however they will not really be seen behind the wheels so this will be fine. If i find some old etched parts in my box of bits i may retrofit them later. and with a strip of 12mm nickel silver flat i made up several spacers. The axle bushes were attached before the spacers. I used the poppy's jig here to make sure the frames went together square. I'll probably have a look at the cylinder/motion bracket support assembly next. Dave
  6. It's been a while but with time to spare during the last few months i've resurrected the build of the C1. I picked up a copy of Locomotives of the LNER part 3A which gives an excellent history and comprehensive building details which is impossible to extract from the Isinglass drawings. Like Guy Williams i will hopefully use the London Road Ivatt self trimming tender so i'm just concentrating on the engine. Updated plans and elevations with a motor and high level gearbox combo vertically into the firebox. It will also work with the motor horizontal too. I'm in two minds about the trailing wheel, i've shown it as though it were to sit in a slot for the axle which will have tabs on the bottom with wire to stop the axle dropping out as Comet tender chassis do, the axle will then have be restrained by a pivot rod from the rear spacer which will allow some vertical movement as well as a little side play. The big concern however is the clearance between the bogie and the cylinders. I guess i'll just have to see how it goes. The driver spacing has been opened up slightly to accommodate Gibson wheels. I've also laid out most of the constituent parts so that they can be used as templates for cutting out. Dave
  7. Some more rock debris added to the process end of the operation. I've more to add under the drops at the side of the conveyor which feeds the elevator. I'll weather the conveyors, supports, elevator and loading hopper next and after that i can think about adding the smaller details, pipework, pallets of slabs, large stone blocks for the cutting area etc. Dave
  8. I've made up the back scene at the left layout end by using more Scalescenes brick papers to replicate the far side of the bridge. A couple of additional buildings have also appeared at the front, the weighbridge/offices and a loading area that will have slabs and prepared stone stored on. The jib crane is only provisionally positioned with blue tack. The weighbridge/office building has a small flap in the rear so that i can access the sector switches underneath it. the slide switches for 2 of the points are under the loading bay which will be removable. I've also started adding some rock debris which will be augmented with dead grass etc later. I'm awaiting a cast resin tank that will sit in the area between the bridge and office hiding the other 2 slide switches. The access to the main line will be fenced off with gates across both the access road and the line. Dave
  9. At the end where the lines run out to the cassettes i had temporarily set up some foamboard guides which i'd intended to be the base of the bridges i had in mind. So i've made up a double bridge from the newish Scalescenes Plate Girder bridge set. The bridge is tapered and also slopes from right down to left a little, keeping minimum clearances over the access to the main line (60mm clear). The only thing i found with this was you need to really read the instructions and understand exactly the dimensional relationship between the deck, abutments and girders before you start. The foamboard supports were not needed in the end as the bridges as all the other Scalescenes buildings i've made up are all very robust. The larger left hand bridge will also incorporate a roadway. Dave
  10. The layout has progressed a little since the last post. It took quite some time to get the initial sand and then a thin layer of das clay down in and around the sleepers and rails, but after much cleaning up around the point blades etc it's all running smoothly after a test run with my 50550 class. The quarry is Millstone/Gritstone, unfortunately the strata with the mould from Woodland Scenics is more akin to limestone rather than the blocky more angular faces associated with the Dark Peak but it'll have to do. Adjacent to the drops is a small Stone Cutting workshop with loading/offloading facilities provided by a runway beam overhanging the tracks. I've raised this area up so that the flat wagons will be at or around the same level, a loading bay at the nearside will allow loading of the cut slabs onto small flatbed trucks. A small office built into the rock face completes the structures to this area. To the rear of the above area is the power house with fuel tanks provided in a bunded area, there will eventually be pipes etc from the tanks to the power house and main plant building. I've added an initial colour for the rockfaces which after years of neglect will have lots of moss, grass attached etc The buildings are all just placed temporarily until i've got some of the other features like the scenery closing over bridges at the layout left hand side, weighbridge, office, access road roughly positioned. I can then start to add some foliage to the tracks which will hopefully start to make everything look ok. The red curved roof building to the left of the main plant building is a quarry machinery workshop (the double doors are camouflaged by the paint) and covered engine shed affair, this will have a raised diesel tank to the front and a water tank on the roof. i've made a small low level loading area which will give access for bulldozers/backhoes/loaders etc to be loaded onto loriots or well wagons. Dave
  11. Woodland scenics do a tracked loader as a kit or ready made, they also do a nice bulldozer and an Insley backhoe. They are HO 1:87 though.
  12. Hi Dave i got them from Fox they're in the general lining section, they call the colour "off white". I must admit i missed them at first look but it was Worsdell Forever that nudged me in the right direction. Dave
  13. After making a start on the main processing building i needed the elevator structure and consequently most of the items associated with it. These being the belt roller conveyor under the drops, the elevator loading hopper, the elevator (which is from a ratio coaling tower), the elevator support structure and the conveyor to the main building. The conveyor is from a Walthers kit, but needs a conveyor belt adding to it as well as a conveyor extension to behind the discharge chute from the elevator. The structure is built from various Evergreen styrene components, the ladder is from the Coaling tower kit and lands onto the access walkway, there will be a short ladder from the the platform at the top down to access the conveyor walkway. The loading hopper and drop belt conveyor are all scratch built from various bits of styrene. Everything in the photos is just placed and nothing is fixed in situ yet. It all needs painting and the ground cover and other buildings need finishing beforehand. As you can see i'm progressing with the rock moulds, again nothing is fixed just placed, there's still a few to do. But next up will be track ballasting and areas surrounding the track, i'm going to use Chris Nevard's method here, sand as a sub layer and das clay pressed into the sleepers to build the levels up. Dave.
  14. The last few days has seen a parade of castings from the rock mould, there are quite a few and i'm managing 2 or so a day with das clay. I take them out before they've hardened so that i can contour them while they are still maleable. So whilst that is going on i made a start on the main processing building. I first produced a Cad drawing of the layout so the dimensions of the pieces would be accurate. It's a truncated wedge shape and will have conveyors coming into it from the elevator and exiting to the loading screens and possibly a silo for the finer grade waste products. It's made from 2mm card with scalescenes brick paper at the lower level and Slater's ribbed sheets scored at 3'-0 wide and cut to 8'-0 lengths which are PVA'd onto the card face. The stairs are from Plastruct but the walkways, ladder and handrails are scratch built. The walkways access those which will run along side each of the conveyors. I have some dust extractor units made up for the left hand end. I'll give it a prime coat next so i can add the windows and finish the roof off. I'll add more details when i get around to giving it it's final paint job. After that then i'll start on the elevator structure and conveyor between the 2. I have a Walthers kit for the conveyors which are very nice but they will need a little titivating where they access the elevator. Dave
  15. I've laid the track onto foam board which allows me to cut slots in for the wire in tube, the track is fixed with copydex which dries fairly quickly. I've marked out approximate positions for the mayor buildings but no doubt things will change once i get into it. The switches will be covered by buildings/ features with access only required for the toggle switches. I had already made the drops and walls for the sunken area prior to track laying, the rails are fixed directly to the sub frame made from evergreen I beams. As there is going to be a building behind this area i've made a walkway that will cantilever from the piers and will eventually give access to the the lower level. This area will have the belt conveyor under the drops which in turn will take the material to a hopper feeding directly into the elevator. I have a Ratio Coaling Tower and will probably use the elevator from that along with a scratch built framework. I'll take some close up photos once i've got a few of these items ready. Once these structures are finished i can then position the main grading/processing building as the conveyor leading to it feeds off the elevator and will form part of its structure (hopefully). Dave
