After our first brainstorming session, we finally fitted in the time for our first planning and design meeting. On the agenda was to absolutely confirm the basic concept of what we wanted to achieve. The decision to go with a freelanced body was all but set in concrete and the fundamental mind set of over-engineered design was put in place. The over-engineering will allow for the provision of a heavier prime mover and drive train, and also the ability to fit 2 3 axle power bogies of up to a 10.25 inch gauge. Prior to the commencement of fabrication we will be creating a 3D model of the major components including the OEM parts. Each stage of this construction will be carefully calculated to achieve maximum safety and performance. We estimate the 3D model will be completed in approximately 7-8 weeks with the first stages of chassis fabrication to start directly after.
At this time we are looking to procure the Prime mover for the loco, and after a change of heart and wanting a more challenging install we have opted for the 4lt EFI Ford 6 cylinder. The reason behind this is to not only create something more unique, but it will force us to engineer the chassis etc to carry a greater weight than a 4cyl, it will also mean we will have to create a drive train capable of withstanding a substantially higher torque of 300+Nm. But in turn this will allow a higher hauling capacity, and later on down the track when we hope to release our design to the purchasing public, and provide a sturdy basis for others to power their version with anything up to and including the figures of the Ford 6.
Comments are more than welcome at this stage, although Ben is a experienced engineer and I have a good relationship with locomotion, it is our first leap into the world of miniature railways, so please offer ideas thoughts and questions as it will help us form what we hope to be a very successful project.
Next step donor engine testing!
