Part Selection

The engine arrived some time ago, and over the last couple of days, we've been making preparations to have the engine scanned and ready for insertion to the updated model in SolidWorks (as seen in Vehicle Build Process). This involved installing some of the parts we had to order separately from the engine, and also removing some from the complete vehicle we already have in the shop for benchmarking in addition to updating the scanner software, installing the IR targets for the scanner etc.

Having a complete vehicle has (and will continue to have) a profound affect on our ability to assess which parts come with certain assemblies, and those that have to be purchased on their own. Therefore, as I said, some of the parts we need to get the engine to a running state did not come with it from the factory, so we are making careful notes on such parts and ordering accordingly. Despite the fact that production is quite some time away, we can place orders for parts accurately and quickly when the time comes if we are diligent now.

Conversely, some parts we purchase may not be used in the prototype, or may come with other assemblies, so we will keep track of these parts as well. In the case of such parts, not using them is often a decision that must be made after purchasing the part, installing it and finding that it simply won't work for any of a number of reasons - too heavy, too expensive, interferes with another part etc. However, all is not lost on such parts since it is often a means to an end, and it provides a great deal of learning. Sometimes learning what doesn't work is how you determine what does work.
