  1. Have you checked the slicer files for the ones printed on the plate to see if there is a "hole" in the files near the top. You can single step through the files on the Chitubox slicer to check things out. I've had the occasional "funny" on Chitubox when a slice doesn't represent what it should which I have got rid of by doing something like rotating the part a degree or two. In your case, raising the part on supports might be changing things to get rid of the blemish. Jim.
  2. In Glasgow, more likely to be a sandstone wall rather than brick. Jim.
  3. I think I'll stick with the Mini 4K - for a start I've run out of room for any more equipment and my old Shuffle is on the floor at the moment. :-) I have tended to print small objects like wagon springs and axleboxes so the smaller plate size is no problem and my cleaning and curing process is geared up to small items. If I got a printer with a larger plate I would have to get a larger ultrasonic bath to match the plate size. And the pixel size of the larger plate machines is not as small as the Mini 4K and I like the improved resolution on the smaller parts. Jim.
  4. Ian, In a lot of cases when modelling pre-Grouping railways, the smaller 4mm scale rail and chairs are closer to scale than our S scale rail and chairs. Our components are based on British standards from Grouping onwards where the rail and chairs were substantial enough to carry the increased weight of locomotives and rolling stock from the start of the 20th century. In Victorian times, the rail and chairs were of lighter weight and smaller dimensions. I think I remember Geoff Stenner telling me that track on his Victorian era layout had been laid using 4mm components.
  5. Just as a follow up, here's the Vectric web site on the laser add-on https://www.vectric.com/products/laser-module I think I remember it costing about £50 but you also need the latest V10.5 of Cut2D desktop to run it. Jim. [Later] The cost is £39 - just found it digging around on the Vectric website.
  6. I'm just about to start using mine after a lay-off most modelling for a year - its the original Emblaser 1 using Cut2D Laser in its last upgrade form. I reckon there are bugs in this update and I'm looking at using a recent laser add-on to Cut2D Desktop which I use for CNC milling. I tried to have some discussion about the bugs in Cut2D Laser with Vectric a year or so ago but they weren't very interested and I suspect they had already decided to do an add-on to the Desktop version rather than continue with the original Laser version.
  7. Have you adjusted the end sizes of your supports? I remember once adjusting the ends of supports in Chitubox for work on my Shuffle and I had reduced the diameter at the conical end of the supports to 0.15mm when the Shuffle and Phrozen ABS Grey resin had a minimum size of barely 0.2mm. I turned out a few prints like yours until it dawned on me what was going on. Jim.
  8. I go a Phrozen Sonic Mini 4X a few weeks ago and it has worked well from day one. I've run a few tests - like the rook and the Amerilabs test - and have done about ten runs of a NER hopper body which I'm developing at the moment with no problems. I had one failed print but I put that down to a dodgy file for the printer since I've picked up faults in subsequent slicer outputs which I've corrected before printing. I'm using the Phrozen Grey 4X resin and I run the printer in an ambient temperature of 26C - 27C, having built a cabinet to house the printer with a 100 watt temperature contro
  9. Paul, How many dozen do you need? :-) :-) :-) Jim.
  10. Ian, The finish at 0.05mm layer height is excellent - you only start to notice it on the sides when I go in very close with the camera and use quite oblique lighting. Apart from one or two test prints, this is the only model I've printed so far, so my experience of the printer is quite limited. I will be digging out some of my files of wagon detail parts and maybe try 0.03mm layer height to see how good the results are since I have a few prints done of them on my older Shuffle. Jim.
  11. Scott, Just the hopper - Mr. Greene will be doing the underframe, and Mr. Provan has done a nice wee etch of the brake gear. :-) Jim.
  12. I got a new 3D printer a couple of weeks ago and I've used a job I was doing a year ago as a first project on the new machine. The printer is a Phrozen Sonic Mini 4X which is one of the newer breed with a mono LCD screen giving smaller exposure times, and a smaller pixel size giving better definition. The model is a body for a NER 7T hopper wagon, destined for a layout somewhere in the Leeds area. The last picture shows the pile of rejects on the way to the final result shown in the top three pictures. It took a w
  13. More than likely on the right hand side of the firebox as in the picture of the Stroudley single above. That is where the Westinghouse pumps were situated on tender locomotives on the Caledonian where Drummond moved to after his period at the North British. Drummond seemed to be strongly influenced by Stroudley and a lot of Stroudley features appeared on his locomotives designed for the NB and the Caledonian. In fact some of these features were still apparent on Caledonian designs by his successors on the Caledonian. Jim.
  14. Over the past year or so, I've been going down the road of using the 3D prints themselves on models, especially when you are not going to use too many. On even the smallest 3D printer, you can pack a good few parts onto the building plate which offsets the longish time required to do a print. If your intention is to use the 3D print as a master then its quality will be as good as, if not better than, any casting made from it. In the future we might look at the Parts Department holding a library of STL files which are used to print parts when required. This would suit a society such
  15. Rich, I think you might have to start drawing something up. :-) The only bogies I can remember in S were GE bogie sides of which a good few were around some years ago, but no longer around today. Maurice Hopper produced a resin cast Fox bogie side and I think they are now finished, but the masters are still around to do another run if required. Alan Gibson also provided some whitemetal LMS bogie kits. But I can't remember of anything else. I have done a 3D print of a Caledonian Fox bogie and that worked quite well, so you might consider going down that road if you can g
