I have also bought the plans for Steve Hucks' V8 and the blower, but it will be a looong time before I get anywhere near a completed engine  |
Simon I had to walk away from it for a bit, it was driving me crazy. I have been working on methods to make the crank and think I have just about worked it out
. It will be made from EN16 (chrome moly steel) which is quite hard to machine and I will need a number of fixtures to support it as there will be a lot of pressure on the blank and cutting tool. The engine was designed by Eric Whittle and has 550 parts that need to be made (very small parts) I must be mad
. Here is a vid of the prototype running at 7500 RPM with a 12 inch prop.
