  1. Looks fantastic! And are these going to be available.....? Oh, and what wheels are you using? All the best, Mark
  2. Many thanks, Ruston, as I said, uneducated eyes, and although obviously family members, it's difficult to gauge relative size. All the best, Mark
  3. Over the weekend, I also managed to make some progress on one of my Cambrian Railways 4-plank opens, with some detailing done to the solebars and the brake gear added: http:// Having got used to the double vee-hangers on the D299s and D305s, a single vee-hanger external without any other support seems a bit lacking in robustness.....I'm finding it difficult to track down to track down any photos for reference, so any pointers would be appreciated! Etched axleguards are my usual MJT (the straight keep plates have been snipped off to be replaced by curved ones), the frets also supplying the solebar details, and the axleboxes/springs are @Quarryscapes excellent Cambrian Railways Grease Axlebox 3D-prints. I also appear to be running out of wheels..... That'll be it for a while, as I'm away from home until the weekend Cheers, Mark
  4. Just a quick update, hopefully not too wordy! The Coastline Models Cambrian Railways 2-plank fixed side with its prosthetic headstock: http:// This has been trimmed and filed to size now, and hopefully the buffer base will cover the join so I won't need to fill it! The D299s' and D305s' with their door safety chains: http:// http:// http:// http:// I'm really quite chuffed with these! The D299s and D305s have also had their exterior grey applied, and one of each has had the ironwork picked out in Tamiya Iron Grey: http:// http:// http:// The only thing is that I'm a bit disappointed with my picking out of the ironwork - a combination of ever-lengthening eyesight and a slight less steady hand than in days of yore. A bit of touching up will be needed, after which some light weathering will hopefully disguise the duff bits! Cheers for now! Mark
  5. Following the arrival of the various shades of grey paint (which didn't quite number fifty!) I've sprayed a test panel, which has helped me to decide on which shade I want to use for which Railway company's wagons. However, I'm not certain that the shade I had intended for the Cambrian Railways pre-1899 livery for the 2-plank fixed side wagon is quite dark enough, so the jury is still out on that one. Also arriving yesterday were some Cambrian Railways transfers from the Welsh Railways Research Circle, which look very nice indeed. But I shall have to find a small, block lettering number "7" for the loading legend on the same two-planker. That same wagon has had a piece of Evergreen styrene strip let into its damaged headstock, and with the 0.125mm copper wire being delivered, the S&DJR D299s and D305s have had their door safety chains added. Photographs to follow..... Cheers, Mark
  6. This is known as surface dressing, associated with those signs saying "Beware Loose Chippings". It's a cheap way for local authorities to eke a few more years out of their minor roads and improve the skid resistance of the surface. Cheers, Mark
  7. Many thanks, Guy, for the extra info - it sounds like it should fit alright, and the reference photograph I have shows packing blocks behind the buffers which should also help. Best regards, Mark
  8. It does look the part, but it's actually really light! Only the interior and underframe parts have had any paint, so it could be that seen through the translucent plastic, or just the dreadful light! An array of grey paints have arrived today, so I just need to decide on which one looks the most suitable. I'm thinking of finishing this wagon the pre-1899 Cambrian livery, which was allegedly slightly darker than the later shade of grey, with only the running number on the ends and LOAD 7 TONS in small block letters on the wagon sides at bottom left. Ironwork was black, of course. Cheers, Mark
  9. Having had a couple of hours to myself last evening, I thought I'd try to get the Coastline Models Cambrian Railways 2-plank fixed side as near to complete as possible. As mentioned above, the Coastline parts are nicely designed, and printed in Smoothest Fine Detail Plastic they're well-detailed. However, I did have a few minor issues, which were probably of my own making, and Sir Isaac Newton was also partly to blame, but which nevertheless resulted in considerable swearing! To fit the solebars to the underside of the floor required a little filing of their ends until they fitted snugly between the headstocks. The transverse ribs on the underside of the floor also needed a slight trim at their ends, and I lightly scraped the insides of the solebars where they meet those ribs. I lightly filed the tops of the solebars as well, as they were sitting slightly proud of the headstocks. The journal holes in the axleboxes were sized nicely for the axles, but without bearings the solebar/axleguard parts took on a decidedly knock-kneed appearance. Conversely, with brass pin-point bearings fitted, they were rather bow-legged. Trying to hold together two sets of solebar/axleguard parts, four bearings and two wheelsets resulted in swearing, especially when gravity took over! Perhaps different bearings would have given a better result, but my solution was to drill out the holes to ensure they were deep enough, and then countersink them until the flanges on the bearings were flush with the surrounding axleguards. By doing this, I achieved the desired verticality. Here, I've drilled out the journal holes and countersunk them: http:// Looks dreadful, doesn't it? At least its not visible! One solebar/axleguard part glued to the floor: http:// I used Zap medium cyano for this, and allowed plenty of time for it to cure before moving on. The bearings are in their pockets: http:// After fighting to hold the whole lot together with the wheels fitted (more swearing, more gravity!), I glued the bearings in place! In my experience, 3D-printed parts are quite brittle. So, not being sure how flexible the axleguards would be, I elected to fit the wheelsets at this stage, even though they'd be trapped in place: http:// I prefer to have the wheels removable to ease painting, but I'll just have to be a bit more careful! I'd also fitted the brake gear when I took this photo. Its a nice print and fits perfectly between the wheels. From what I've seen in photographs of this style of wagon, no safety loops were fitted! Unfortunately, it was then that I noticed the corner of one of the headstocks was missing in action: http:// I suspect it may have been from when I dropped the wagon body..... Finally, a couple of shots of the nearly-completed wagon: http:// http:// I need to repair the damaged headstock, but all-in-all not too bad for a couple of hours effort! For buffers, I've got some of @Guy Rixon's 3D-printed LNWR Self-contained buffers on order from Shapeways, as these are the closest I could spot to the type of S/C buffers found on some Cambrian Railways wagons; the MJT S/C buffer heads arrived this morning. I'm not sure yet whether I'll be able to spring them as the solebars obscure about one third of the diameter of the buffer sockets in the headstocks. Cheers, Mark
  10. The macadam, as devised by John McAdam, relies on the interlocking of the stones in each layer to provide structural strength within the pavement's construction. A quick look a Wiki doesn't seem to mention how the stone should be graded - the graduated sizes of stone aid the "locking" as each smaller size fits in the gaps between the larger ones. The addition of tar and subsequently bitumen to the mix as a binder acts as stabiliser and keeps the structure intact (assuming no ingress of water and freeze-thaw!). Its quite likely that the lower layer shown in the photograph is the original unbound macadam. Most minor roads in England consist either of an unbound macadam as per the photograph which has been overlaid by bitumenous materials, or they are simply layers of tar/bitumen and chipping accumulated over time. In modern pavement construction there is an un-bound layer of coarse stone (sub-base) beneath the bound layers. There would also be a thick capping layer beneath the sub-base where ground is soft. Above the sub-base are three bound layers, the base, the base-course, and the surface course, all diminishing in thickness and aggregate size as they approach the surface. For anyone who's interested in modern pavement design in the UK, I can do no better than recommend the Design Manual for Roads and Bridges
  11. The colour of a bound macadam or hot-rolled asphalt pavement (the bit you walk on is a footway, the bit you drive on is a pavement!) is determined by the aggregate used. The aggregate is bitumen-bound (tar is highly toxic and fell out of favour long ago) and the near-black colour of newly laid pavements is the colour of the bitumen, which naturally wears off with trafficking leaving the aggregate exposed. The choice of aggregate in a bound macadam or HRA is dependent upon the required skid resistance of the surface. Cheers, Mark (30 years a highway engineer ) Incidentally, a hot-rolled asphalt is simply a bound dense bitumenous macadam with coated chips, usually minimum 14mm aggregate, rolled into its surface.
  12. Hi Mikkel, yes, the Coastline prints are splendid! There is a slight surface texture on them, but its scarcely detectable, and externally runs with the grain of the side sheets. All in all, I can highly recommend them. I'm also using Alan's Cambrian buffer and axlebox/spring prints on these and the Cambrian Models kits, and they're also extremely nice. As to whether the quality of Shapeways' prints has improved, I couldn't say. I've had a few prints in the past from other sources that were most disappointing - I suppose I could buy another of the ones I was disappointed with to make the comparison (the manufacturer in question has a number of models I would otherwise have snapped up, but haven't), so it might be a useful exercise. All the best, Mark
