  1. Do us another 20 and we'll have em . Sadly not quite for Castleton but they do look great Tim!
  2. Maybe the Class 42/43 discussion should move to a new Dapol D800 Warship thread .
  3. Some stuff here, there was a full thread somewhere here but I can't find it. http://www.rmweb.co.uk/community/index.php?/topic/26882-class-42-warship-boiler-roof-details/ Brian Hanson does the two type of roof fan grille and walkways that were about. I think a bigger different variant will be doing the original front end with 3 letter reporting code. (The one Hornby have attempted with paint!)
  4. Educational and funny Mr Ste(v)phenson

  5. P4 shouldn't be an issue for wheels as Ultrascale will have no issues with disc wheels unlike the spoked wheels needing live stub axles on the cl22. I'll be prepared to move bogie detail around if needed on these after getting an accurate bodyshell. A bigger issue may be if its a completely rigid C-C arrangement but if the gear train is in line then hopefully it could be sprung (or fit Heljan bogies!). Once Mark is happy i'd certainly look forward to metal cutting for that body though . I hope there are no complaints about the nameplates, I think Dapol has an excellent compromise in place there.
  6. The diagram is in the NRM in the ex-OPC aperture card collection, card 644: 644 Microfilm aperture card 1 Great Western Railway Maker of original drawing 4-4-0 Tre Pol and Pen 102 A40 Weight Diagram You'll note it was a one off weight diagram specifically for Tre Pol and Pen. I don't think it was one of the weight diagrams I found when I went through a couple of boxes of the originals though.
  7. Should the handrail follow the vee shape too? (upwards aswell a outwards..)
  8. Yes it is quite a small area but its pretty strong on a chassis with no metal issues. Even the main bulk of the chassis block had started going and the screw pillars snapped off on mine when it was sent off.
  9. I can't imagine not driving the rear axle even if it was fully sprung, being rigid shouldn't make a difference there.
  10. There is a wants area http://www.rmweb.co.uk/community/index.php?/forum/39-wanted/ . The blogsare for showing off work being built.
  11. Can't you fillet the circumference of the top of a short cylinder to produce a rivet in Sketchup? Archer rivet transfers may be easier though or a half etch overlay to stick in each side with the detail on it.
  12. You dont need to do anything with resistors if there are any on the model. They will be there to slow the motor down. What you remove are the capacitors that provide interference suppression on DC. The capacitors are usually on the end of the motor across the two connectors. You just snip the one leg and leave them there but disconnected. Removing them should make all decoders work better as the decoder will be getting a true back EMF then from just the motor.
  13. Ultrascale already have P4 wheels for a Western which could be produced for this model. The issue with the class 22 is producing conductive spoked wheels for use with the split axle pickups.
  14. Parkin quotes a mk1 at 9' wide 6' 11'' above rail height, the throwover diag shows a Western at 9' wide at the same height. The Western though is shown as 27' 5 7/8'' radii centred at the 9' wide mark against the mk1 at 28' 1 7/16". If Dave can dimension a cross section at the points I sent him we should be ok. Hopefully Mark will read all of this anyway and tell us what he measured. Unless China has fiddled with his CAds the original model produced from them looked fine.
  15. Could always get a slice of main bodyside cross section 3D printed if you want to convince people.. In fact posting a cross section at the midpoint may be useful to stop features getting in the way. Throwover btw in a BR context seems to be calculating which bits will stick out and by how much on a particular curve. Ie working out if your loco is going to take a chunk out of the platform when traversing the loco release crossover.. This particular plan shows the body centre throw on one side and buffer etc throw outward on the other side when the loco is traversing a 6 chain curve.
  16. The profile used for the throwover calculations gives a radii of 27' 5 7/8'' with a centre 2' above the deckplate of 9' across (dimensions over outer skin). 4' 11'' top of deckplate to rail.. SL/SW/2689 Throwover diagram for 2700HP DH C-C Locomotive I'd hope the dimensions here were correct as they were used to calculate clearance against the L1 load gauge.
  17. I was thinking more of the split between DCC accessory power and track power. Either using separate boosters or circuit breakers on the track to protect the command station allowing it to still change the point motors. Your sectioning make sense though. We've got 5 pairs of bare copper sub bus on slattocks approaching the junction - Bury up/down, rochdale up/down and the goods loop and we'll probably add one for our yard there too. These are currently powered off either of our two 5 amp boosters so the down and up trains cant short each other out. Its also how we've had DC on one circuit and DCC on the other. The only issue i've had so far is Dick having a lose screw in the choc block on his DC controller! I suppose you could laser cut mounting plates in a decent thickness of ply for the Cobalts perhaps? You may have to manually countersink them though. I do think its an improvement even if you had been alright with your newer C+L. Thanks for that, its a relief to have something to get back into after xmas. I'll be down in Cardiff Thursday for a decent break before I start.
  18. Click 'More Reply Options' button and you;ll get a box to add attachments to your posts. Obviously compress the jpgs quality a bit for web so they end up about 500kb or less if you can.
  19. Could you just post the pictures directly to rmweb rather than trying to link them in? Its taking a while for them all to time out at the moment.. I'd agree with you on using one of those cone shaped grinding things (Normally pink or green) as i've done the same though manually file sometimes too. You've obviously grasped the wiring nice and easy too
  20. Tie bars (as opposed to the prototypes stretcher bars) normally consist of either two right angle bent wires in a sliding sleeper above the board or passing through the board into a sliding bar underneath. The cobalt would then drive these solutions through a hole in the sleeper/bar. If you were using Tortoise motors then you could have used the Exactoscale mounting plates which use the underboard bar method. The right angle bend wire is simplifying it slightly as you normally need a more complex arrangement that slots under the stock rails to ensure the switch rails can't rise up and cause issues. There is an example of this solution here http://www.scalefour...5&t=1700#p13237 Btw looking at your template there seems to be a mark on the switch rails which I assume shows the fishplate joint between these rails and the closure rails that joint the switch rails to the wing rails. For a prototype flexible pair of switches only two chairs would be fixed. This probably only works though if you choose to do longer prototypical turnouts such as a B7 etc. The approach you used seems to have worked fine here. I tend to use a flexible surface (mouse/cutting mat) to file the blades against as it gives a natural curve down towards the tip which can be useful in the curved rail although not always prototypical (The GWR though always had curved switches). Good work .
  21. They'll be waiting for a batch of cl31's to be build on the production line in China so they can tack some more chassis on the back of that to do the repair work. We all know production slots in China get chopped and changed a lot and also how long stuff takes on the boat so its not surprising the details are varying in my mind. Im guessing they've run out of the original extra batch they got done for the initial wave of returns.
  22. Thanks Rod. Ken (oil-burner) actually pm'd me jpg copies but it good to have them in this thread for others to benefit too.

    Dapol Class 22

    Yeah but imagine what happens when D1000 turns out needing to be D1030 due to a detail difference in the tooling :? ! (numbers picked out of the air, im not suggesting an actual difference between those two! ) "Yes sir you did order a D1000 and your model of D1030 is on its way.."
  24. When Paul said you had that working i;d thought he meant attached to the layout.. I'll be interested to see the mounting bracket you use on them when Chris has one for you. Are you going to run them off a separate power district or just fit a circuit breaker on the track bus? I think keeping ply plain line on the mainlines will be worth the extra efforts.
