  1. There's a prototype for everything.... Edit: what happend to the buffer of this wagon? It would not be used in regular traffic like this I think?
  2. There's even a picture of the Aerofilms De Havilland with photographers: https://artsandculture.google.com/asset/francis-lewis-wills-jerry-shaw-and-claude-friese-greene-in-a-dh98-biplane-aerofilms-ltd/kAH9r_6ojIczUQ
  3. Rumpler would be for the gloat box of coarse
  4. Could this be something? Bit too large but maybe acceptabele. https://www.emodels.co.uk/valom-1-144-bristol-f-2b-fighter-vs-rumpler-c-iv-14422.html https://en.m.wikipedia.org/wiki/Bristol_F.2_Fighter Jan
  5. Guy, I've edited my post to add an important step. And I'm very happy with this little lathe. I started with a Chinese lathe which worked ok but the Taig is much nicer!
  6. This is exactly how I replaced the rims on my Dapol Terrier, altough I used the tailstock to press the wheel against the mandrel. This is my Taig lathe with the tools I made up to hold the wheel. A mandrel with a spigot which is a sliding fit for the wheel. No damage to the axle hole because no pressure is needed to push the wheel on. End of the spigot is turned down to 1mm and fits in the part that presses against the wheel. The first red arrow points to a plastikard disk with 400 grid abrasive paper to transfer the lathe power to the wheel. Hole is large enough to clear the inside of the wheel boss. The other arrow points to the part that presses the wheel against the mandrel. 1mm hole to engage with the spigot and a shallow larger hole to clear the front of the wheel boss and only apply pressure to the outside of the wheel. Step 2: wheel placed on mandrel (with plastikard disk behind it) Step 3: turning down the rim. New rim is placed on the pressure part so it is easy to test the fit without disturbing the setup. Step 4: turn a 0.25mm deep recess to clear the front of the new rim. Outside diameter of the pressure part is the same as the inside of the new rim so the depth of cut is reached when the tip of the tool touches the pressure part. This is quite important because the new rim can be pressed against it and will run true. You can just see it in the view below. The three stages. Unfortunately I can't remember how I turned down the back of the wheel. I think I used a piece of plastic turned square with a hole in it for the wheel rim. Push fit and the wheel supported by the tailstock to prevent it from working loose. Very light cuts until you reach the new rim. Jan
  7. Simon, Without the coupling rods it shouldn't be difficult to find the tight spot. Just turn the worm one revolution at a time and repeat that 30 times (on a 30:1 work that is). In every position rotate the wheel slightly forward and backwards, without force that is. There should always be a bit of play between the teeth of the gears and with this method you can see that for every position of the gears. Check the spur gears and the worm gear of course... Jan
  8. I never built one but it seems to me that the pegged easitrac turnouts (shop item 1-401 etc.) with milled crossing will be by far the most forgiving option. I've built copperclad and 'normal' easitrac turnouts and the latter run very smooth. Disclaimer: the easitrac were also my most recent turnouts so I had more experience... Jan
  9. I think that your solution with a decoder is much better because it gives the motor more torque at such a low speed.
  10. Your remark made me wonder if this could be solved easily on DC and it can. Just add an extra diode and connect the microswitch like this: If voltage drop over the end switch was your problem of course.....
  11. Thanks Chris and Jim! I didn't think of the brittleness of the resin but something in the back of my head kept telling me that it would be difficult to remove the printed frames from the support without breaking them. I'll look into the possibilities of laser cutting in card: https://snijlab.nl/en/m/196/resinboard-0-5mm Jan
  12. Would it be possible to print window frames and doors for buildings etc? I'm scratchbuilding a station building and railway pub and of course I also have to make the windows and doors. There are possibly better options for windows like etching, laser cutting or even a craft robot but if a Photon printer can also be used for it that would open lots of other possibilities like coach roofs, loco parts, etc. I have had some of my own designs (platform edging, foundation and walls of another station building) printed by Shapeways already but that's quite expensive. The reason for asking this is that I always see a relatively large base for the prints and I was wondering if such a base with supports could also hold a delicate window frame. Jan

    I found some interesting images: https://www.gettyimages.nl/detail/nieuwsfoto's/privately-owned-railway-wagon-1938-workers-unloading-coal-nieuwsfotos/90747028 https://nl.pinterest.com/pin/339881103121045221/ https://www.warwickshirerailways.com/gwr/gwrc3.htm
  14. Would it be an idea to leave the layout as it is and then add a removable side at the 60cm position. You only have to move the small building on the front a bit to the right. Looks less cramped than your mockup with the turnout moved to the siding I think. The DLJC rules only restrict the dimensions of the scenic area but you're free to do what you want with the offstage area. And of course you have to cover the front on the left side but it must be possible I think. Jan
  15. Maybe it's better to just wait and see what happens. It could be wise not to book your layout to a 2021 overseas show until everything is clear. I'm glad I can still bring the little layout I'm working on to the DJLC in June! Jan
