I have worked from Brians original drawings to create an accurate 3D model using SolidWorks. From this model I am producing component drawings in PDF format. Currently I have completed the drawings produced and they are available below. Most of the main drawings are checked and should be complete. If anyone is planning to start making an engine from these drawings I would strongly suggest that you email me so that I can keep you posted with any changes, updates or improvements.
There is also an easy to use 3D model of the assembled engine that can be spun, sectioned and exploded to further explain the design. For more information on how to access the reading program to use this model please go to the CAD TOOLS PAGE
You will see that there is one major difference between the original prototype and the drawings available here and that is the venturie is now on the engine centreline not offset as it is in Brians prototype. The experience of using the original engine in competition for the second half of 2008 has indicated that the slightly improved engine balance is not discernable in the running and is an unnecessary complication in the machining.
I have also included a normal prop driver for any one who prefers to use a commercial spinner
