Farm Boy Hit and Miss engine

I have made a side project so that I can make the springs for the valves. This is it ready for a test a lot of work for three springs but I do have a use for it after this project.

All the parts



Fully assembled



I will show the springs once I make them

And of course even though it’s “just a tool” it’s beautifully made.

I’ve no idea how you would use that to make springs but I look forward to finding out.

Have a look HERE hopefully I manage to start it where it shows it in operation. If not it is near the end

Oh that looks fun. Thanks for the education.

Not done much on the little engine latley as it is spring and catching up with some gardening, I now have in the region of 400 plants I have grow from seed divided between veg and flowers. But I am back onto the engine trying to make some parts for the ignition as I have all the electronics for it and a tiny spark plug. Machining plastic is great for tangles.
Will post some photos as I get the chance.

And yes the spring winder works a treat have now made the inlet and exhaust springs, it is certainly making them easy to produce.

Just a few photos and what I am halfway through on the engine.

First a picture of the spring I made in position on the head.


And all the ignition bits and bobs as well as the spark plug, a 1p piece for scale.





And finally, a part machined plastic piece to hold the wiring and sensor. A magnet will be in a part attached to one of the flywheels which I have yet to make.



Still needs some machining, but this shows where it will fit
