Gauge IIm/LGB (1:22.5) "Rollwagen" / Transporter wagon

prusaprinters

<p>This is my interpretation of the "Rollwagen" used in (East) Germany to transport standard gauge wagons on narrow gauge tracks. Several are still in use, amongst others at the Harzer Schmalspurbahnen (HSB). <a href="https://en.wikipedia.org/wiki/Transporter_wagon">https://en.wikipedia.org/wiki/Transporter_wagon</a></p><p>In Gauge II/1:22.5 the narrow gauge track is standard LGB 45 mm rails. (Gauge IIm) The standard gauge wagons run on 64 mm wide track.</p><p>I tried to capture the main features, leaving out the unimportant details that are hardly visible, difficult to design and print and are fragile.</p><p>According to my calculations this "Rollwagen" should drive OK through LGB R2 curves (radius 780 mm - centre of track). To avoid de-railments I advise to run this model on layouts with at least R3-curves (1195 mm).</p><p>Construction:</p><ul><li>All parts are glued together using CA-glue/superglue.</li><li>Saw the heads off 4 M4 bolts and screw them in the threaded holes of both frame sections. (M4 thread on 1 side, 4 mm holes on the other side) Slide the 2 frame sections together after some glue is applied.</li><li>The bogies are screwed to the frame with countersunk M5 bolts.</li><li>Glue some 1.75 mm filament to the hand-brake-wheels and glue them to hole in the frame.</li><li>The adjustable wheel-locks slide on 2 mm steel wire that is glued in the holes provided in the frame. Please don't use filament for this. It bends so easily, the locks can not be kept in the desired position.</li><li>Use 2 mm metal wire to bend 2 eylets to be glued to the ends of draw-bar.</li><li>The coupling pin in bend from some 2 mm stell wire.</li><li>Axles are ~48 mm long 3.0 mm metal rod, with ~4 mm M3 thread at each end.</li><li>The 3.0 mm axles run in F623ZZ bearings pressed in the bogies.</li><li>Wheels have M3 thread to screw them to the axles.</li></ul><p>Have fun !</p><p>&nbsp;</p><figure class="media"><oembed url="https://youtu.be/rK7tvtt_EeI"></oembed></figure><p>&nbsp;</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Creality</p><p><strong>Printer:&nbsp;</strong></p><p>CR-10</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>0.15</p><p><strong>Infill:&nbsp;</strong></p><p>25%</p><p><strong>Filament:</strong> Extrudr GreenTEC Grey</p><p>&nbsp;</p>
