  1. Hi Pete, Not sure about this, but could you use a bank of capacitors instead of a battery, with your track pickups? *(Edit - With Diodes to protect against reverse polarity) That way, no flickering and no switches to turn the LED off. If you really loaded up the capacitance then I suspect that it would stay lit for quite a while and as this is 7mm I suspect you could fit more than in the 2mm equivalent... Best Regards, Chris.
  2. Hi Richard, I needed ash ballast for Callington Road - though to me ash is a lot lighter than your coal dust/cinders mix. In the end I used a base-layer of Treemendous Earth powder and not finding it quite fine enough, put a layer of 'dark grey modelling dust' from Here (no connection etc...) The effect is good enough for me, with the unevenness from the baselayer giving a hint of texture that I don't think I would have got if I had just used the fine powder and certainly better than other products that claim to be 2mm ash ballast. The powders were all held down with a
  3. My first thought was that it was an upcast shaft, but checking the BGS borehole logs told me about the two shafts of 1838 and 1876. Was the upcast in Fenwick C pit to the North? Feel free to ignore the following waffling's and rambling's in preference to someone who knows better. If I were to hazard a guess here, you are probably right in your assumption that the assemblage of buildings was probably something to do with the CPP. My guess is that for some reason, such as the mine moving to mechanical cutting or skip hoisting; that a CPP was required to separate out coal
  4. Hi Richard, I'm not sure exactly which building that you mean, the tall concrete frame with brick/window infill building? It looks pretty empty in this view https://www.aditnow.co.uk/Photo/Historic-Photographs-Of-Fenwick_103247/ Best Regards, Chris
  5. Hi Andrew, Don't get me wrong, I'm not bashing OpenSCAD and it is the only 3D tool that I use. These issues really are just minor niggles and nusances I've run into once or twice before, not every time that I use it. If I had the time, just thinking about optimising how I build objects, and not being lazy when coding, I would probably solve these problems. The preview will only get you so far down the build tree before it gives up (100,000 elements is the default I think.) It also throws up views like below when you get to edge sums. 100,000 elements sounds a lot, right
  6. I know that @D869 of this parish also uses it to produce his tank wagons, and the occasional coach roof. Some bloke also wrote up a quick and dirty user guide in the 2mm mag in October 2018. Sometimes I wonder about the amount of graphics memory resources it uses to do fairly simple operations. Re-rendering the entire model every time you make a change to a parameter is also pretty irksome sometimes, particularly when it's measured in minutes rather than seconds. The viewport also has some nuances that can make it annoying when you're dealing in sub mm units.
  7. Does this mean that you are moving (or thinking of,) away from OpenSCAD Chris? Best Regards, Chris.
  8. Morning Eeyore Rich, I have a couple of pieces of Laurie track and Easitrack left over from doing my trackwork, a quick and dirty measure with my calipers... (and by no means a comprehensive survey) There are quite a few spots on my layout that have a similar difference in height as yours, even on an easitrack to easitrack joint. I think what happened with mine is that the bend on the rail can often spring the rail upwards at the join, above what the last chair can resist. Soldering near the chair will also soften the plastic, possibly allowing more bend to come u
  9. Just to prove that it's all horses for courses, my personal preference is to draw the parts in an older autocad style program, using closed plines. Then import the dxf into inkscape, scaled 1:1, set the line width to 0, and fill the shapes with front etch, back etch, and no etch colour's. Tabbing between parts is normally done in inkscape using rec shapes, again with 0 line width. Front and back images are then created by using the 'Same Fill select' tool to fill in the half etch colour's, black or white. The back image is then mirrored vertic
  10. Is it a 517 perchance, from the title on your youtube video... Nice work as always Ian! Best Regards, Chris.
  11. Hi Ian, coaches are looking good. Very timely as I've recently been distracted by some coach kits too. Do you have a mock up that you could show of this? I've always been shown the 'cardboard jig' method of forming coach sides. This often seems to bend where you don't want it to, like at the bottom of windows, and not where you might want it to, like down to the bottom of the side. Best Regards, Chris
  12. Originally, I’d planned to use a train-table style fiddle-yard, however an in-field adjustment when transferring the track plan to the boards meant that there wasn’t then enough room to get both tracks to be perpendicular to the radius of the deck at the same time anymore. The lack of space that I had left myself to put in alignment bolts over the gap was also going to mean an overly complicated arrangement for this as well. The foundations of this design had been a wide thrust bearing, which meant the deck was specked up for 500rpm. I was going to use strips of
  13. Hello All, Like a lot of people, I think I’m ready to make the transition from Blog entry to dedicated thread for showing and telling what I’ve been doing modelling wise, hopefully this will lend itself to more short and frequent updates than the long prose that have I’ve been writing previously. Firstly, I’ll begin with a short recap, to get everyone up to speed. I’ve been trying to build a model of Callington Station, on fringes of East Cornwall for around 10(!) years now. I know, yet another Cornish BLT… However, staying away from the holiday destinations
  14. Has the resin distorted whilst it was curing - or is it a prototypical BR curly sandwich? :-D Best Wishes, Chris
  15. Personally I'd like to see some of these on your layout Ian, caption in 'Edwardian Devon' says 1906 so should be spot on for your timeframe. Best wishes, Chris.
