Changing/Adding spring on Sanwa JLF

Can anyone provide a walk-trough or link to a tutorial on swapping or adding a spring? I’vce tried searching, but all I can find are spring suggestions. I want to make the joystick stiffer. Its too loose imo. Thanks.

Here’s a thread that has link to a video about modding JLF

thanks. found ahikablahblah’s video on spring changing through your link.


there it is in case anyone else needs it

anyone know which spring to use to get close to the feeling of a happ stick?

HAPP sticks are harder so I guess the closest spring would be the JLW spring, though the JLW spring doesn’t fit the JLF. Well I’m not sure if it doesn’t, but it’s definitely a hella lot thicker.
