Now I have "free time" I am starting to build the Beng Laura engine.
I think I will be able to manage most things (I hope to use a Seig SX2 mill and a Seig SC3 lathe) but one part has me struggling.
The aluminium piston has to have a bullet shape machined into it to fit a glass test tube cylinder. The radius tool for the lathe is not available and I simply cannot afford the expensive tools.
Can anyone suggest a simple way of machining the shape.
I was bought the lathe as a retirement present having always wanted to build a diesel engine since I was introduced to lathe work in the 60's at school. Many years have passed since then but the desire to build something that moves is still with me.
Thanks, and I hope everyone keeps safe and fit in these sad times.
