  1. Hi Ken, sorry, I was back to front, I assumed it was a 2-4-0! The compensation “thing” only matters if the track isn’t flat! watching as always with interest atb Simon
  2. Ken it looks to me like your chopper has two compensation beams, and a fixed axle. This is a recipe for potential frustration, as it will remain a “four legged stool”, whereas true compensation should always resolve to three points of contact (or legs on the stool). I’m not sure how much it’ll matter, and I know you’re not a huge fan of compensation anyway, but forewarned is, as they say, forearmed. Ideally there would be a single, central rocking beam between the central and front axles, if the rear is fixed. will be interested to hear how it runs.
  3. probably, and there will still be nowhere to park
  4. Ashpan adjusted, rather less of jaunty angle! Steps also fitted, with reinforcement at the rear. Hopefully I’ve left enough space, but will have to shorten the screws I put in for the crankpin bearings before I get the motors running again. I’d like to get the upper works more or less done before starting on the details for the engines themselves. The list will probably grow but hopefully this is most of it - rather more than my previous attempt! Horizontal boiler handrails, Beading round cab doorway & vertical handrails handrails on bunke
  5. Oh, yes, it can be much, much better. Probably costs more, but think how good the Modelu figures are. still , it does look like a 503! atb Simon
  6. Made a start on the cab steps today, but further inspection confirms the [email protected]#£&y ashpan is still not quite right, and will need a little “adjustment”... maybe tomorrow! atb Simon
  7. Thanks Phil, I had seen it, but rereading it confirms my intended approach! more soon Simon
  8. Well, three forwards and two back... not really much to report, though the rear bogie pivot is now fixed properly, and the temporary decoder and wiring has been removed. The ashpan has been removed and refitted AGAIN, and hopefully, for the last time. It’s now soldered to the main chassis frames, and the cab-firebox-boiler-smokebox assembly is now fixed to the chassis with a couple of 10BA screws. Reflection is a wonderful thing, it suggests points where foresight would have been an advantage, as I’m now thinking of how to build up the engines. I think the motion brackets will
  9. We had corgis from when I was six. I had a Welsh pal who told me that the name was derived from “Gurra” (hurry up) & “ci” or “gi” (dog) which would make some sense for a herding dog. Regrettably, my command of Welsh is negligible! atb Simon
  10. I recall an article in an old RM, which described an outdoor clockwork line. In addition to the appropriate winding for a given Loco and load, the line had been built so that the trains climbed out of the station (with wound spring), and descended into the terminus & drifted to a halt. I suspect the gradients were subtle. that said, I see no reason why appropriate winding shouldn't be used on a table top roundy-roundy. I can imagine an entertaining session of “guess how many turns to do three laps and stop at the platform”. Would appeal to children of all ages
  11. Been there, done that. Still got a fair amount of N gauge for sale if anyone hankers after it.
  12. Have a look at what Arun Sharma has been up to. Some of his work at Radley Models, and he's done a 7mm HST power car too, and I hope he won't mind me posting one of his CAD images here - rather more difficult than our dear 503's as the windows are curved... image from WT for illustration only atb Simon
  13. That may certainly be an issue, but I’d be more concerned about whether the models would fit in the build envelope, and if not, where the joins would be and therefore how to disguise them. looks good though. atb Simon
  14. I wonder if suitable roof profiles are available. 3D printed cab ends would not be too difficult, given there’s a real one to scan. Ditto the seating. I’d go for etched brass sides, though David Jenkinson style laminated plasticard would work equally well milled brass channel for underframes and Buffer beams, with PCB for the floor would provide a solid foundation. I don’t know anything about the bogies, but I doubt they would pose impossible issues. Steph Dale (Finney 7) offers suitable axle drives and cardan shafts to allow a chassis
  15. Sorted the ashpan, again, I think it will now do. I also soldered some N/S to the inside of the cabsides over the doorways to stiffen them, and prevent damage, and curved some more N/S strip and soldered this to the underside of the cab roof. The roof now sits nicely in position, I’m not sure whether a clip of some sort will be needed, more pondering required. No photos tonight, nothing much to see! atb Simon
