Sentinel Locomotive – Gayundah – On30 (1:48) – Lima Mechanism

thingiverse

The Sentinel Waggon Works of Shrewsbury, England produced a range of steam-powered road and rail vehicles. Their distinctive locomotives had a squat boiler located in the cab and a compact vertical steam engine at the front, driving the wheels via chains. Sentinel locomotives sported a number of different body and cab styles. My freelance narrow-gauge model pays homage to the Sentinel locomotives above the footplate, with a tram-style chassis designed to take the mechanism from a vintage Lima 0-4-0 diesel (See the NER Inspection car model - https://www.thingiverse.com/thing:5392197). The donor Lima models are still fairly easy to pick up second hand and run quite well for their age, especially with some added weight. They can also be easily converted to DCC if desired. My design consists of the chassis, body, cab and buffer beams. The chassis has circular recesses to take four No 2 sinkers for weight. The buffer beams are designed to take Kadee HO scale standard couplers. I attached the body to the chassis with four 2mm x 4mm pan-head screws. The body has holes to take standard office staples as handrails. My loco has been named “Gayundah” (from the Australian aboriginal word meaning “lightning”). Files are provided for a body with this name incorporated as well as a body with blank name plate. Similarly, there are files for a cab with number or with no number.
