crank shaft made from a bolt

[werowance]

i have seen on different forrums as well as this one, 2 stroke model engine cranks beeing cut from a bolt. today i cant seem to find any of those posts.

anyone have any links, or keyword like the name of the engine so i can search it?

anyone know what grade bolt most were using? thats the main thing i was looking for. seems like it was grade 5 in most of the builds i saw but im not positive on that.
