Lazy machinist s valve

[kadora]

This seems like a joke but it woks.
One my friend suggested me to use screws as valves.
I have built one single cylinder and there i used these
screws as valves and engine works.

This is just the information i do not claim that this is ideal valve replacement !!!

Very interesting. One of Bob Herder's engine kits has two nails supplied for the valves, so the ideas aren't so different.
