  1. I've now replaced the window with the broken mullion. In addition to that, all the other details have been taken care of an initial painting has been done. I used a whitemetal crane from Scalelink. In person its a little chunkier than the prototype but I still like how it looks. I added two platforms for the upper storey doors. I think that one of them should have been modelled up, but they're quite firmly glued now. Good think I've got several other similar buildings still to make. The downpipe is 1/16" brass tube with a curve put in at the end. It fits the look I was after. I've

  3. I want to get it right. Constructive criticism is an important part of that. In this case its made me review an aspect of the model I hadn't put much thought into before.
  4. Try printing the axlebox vertically. I bet the hole is there, but resin got trapped in it.
  5. I think its all angles afterall. Compare this picture of the model to this Standard gauge 1076. The model may be a little high, but its close. I think they saddle tank is a bit of a gothic arch at the moment, particularly at the back. This would cause the high point to be higher. But overall I'm thinking its right.
  6. I was thinking that it was just the angle, but looking at the picture Miss Prism posted again I think you're right. I guess I was assuming that the cab was the same as the standard gauge locomotives, but clearly it isn't.
  7. So I'm doing this all in Solidworks. Other CAD packages do things differently. I started with a few concentric circles. One at 1/8" for the axle, then the outside of the boss at a size that looked right, its probably 6mm or 1/4", since the axle looks to be half the diameter of the boss on the prototype. This was extruded whatever the thickness of the Gibson boss is, I think that was 3mm. Then I made another concentric set of circles as a second sketch. These are the outer rim. The diameters are same as the Gibson wheel moulding. This was extruded to 2mm I think. Then I drew one spoke and extru
  8. Since the last post the footplate has largely been completed and the cab added. I've also reworked the bunker to the correct shape. Very easy with a small course file. i'm pretty much back to where I was when I picked up this project again a couple of months ago. The other thing I've been working on is the wheels. The ones I had were fine, I guess. Gibson wheels, I don't remember which code. But they've been on and off the axles too many times to really be useable. They're a little loose, but don't go on the axle squarely. So I could just buy more, but the spoke count is wron
  9. If you’re going for CSBs, spring all three. You’ll loose the smoothness of operation if the rear is fixed. I would aim to have the motor completely above the frames, so go with one of the higher gearboxes. That should reduce the clearance problems in the firebox. The crank pins only need a tiny bit of clearance. If they need to move more than say 0.5mm you’re better off fixing your track problems. A super sloppy chassis won’t run well. Shim the rear axle for no side play, the front for a bit, and no shims on the middle.
  10. Slowly making progress. I had the brainwave of using my CAD skills to make templates and sticking them to sheet metal, rather than trying to draw out the shapes I need on the metal. It worked really well and I now have two valances with the right wheelbase and radius curves, and a footplate to match. I took my time shaping them, I know I usually regret it when I rush. Splasher tops and backs next.
  11. The Scalefour Society makes a kit. Not sure if it’s on sale to the general public or only members. The old version was on sale to the public but I don’t see the Mk2 kit listed in the public section.
  12. No specific examples, but I would be interested in seeing specific examples. I've been seeing pictures of NCB internal wagons and was wondering what they were for, rather than just using BR wagons.
  13. What do I not understand about collieries that necessitates internal user wagons? On a basic level, coal comes out of the ground, goes in wagons, and goes to customers. But apparently sometimes it comes out of the ground, goes in wagons, gets transferred to different wagons, and then goes to the customer. There's obviously something I'm missing about how the colliery processes the coal, but what?
  14. I think the bunker can be adjusted. The flare looks right, its just a matter of shortening the coal rail and adding a couple of curves. I do find it interesting just how much taller the chimney is that the SG/NG versions. Shows just how generous the BG loading gauge was.
  15. I don't remember exactly when I started this project, but the first photograph I have of it is dated 20 September 2018, so it was probably a few days to a week before that. But lets go back to the beginning and discuss just what is being built and why. My friend Duncan decided, as one does, that the ideal thing to build for the Cameo Layout Challenge was a mixed gauge Great Western layout set in Cornwall c. 1890-1892. There's nothing wrong with that per-say, we're all welcome to model whatever odd things appeal to us, but there was a distinct lack of Broad Gauge rolling stock to hand. Existing
