Custom Arcade stick - Something's not right!

Hey guys
I followed the tutorials from building a wooden box to wiring a ps2 (mad catz) controller. Everything is done and the joystick works.

I made a two player arcade joystick. Both sides work but my friends and I find one side to be more smooth then the other. I tried to tilt the directional pad slightly left and right and testing it by throwing fireballs in practice mode but the feel and flow isn?t right.

Anyone else run into a problem like this? And did you guys fix it?:wasted:

maybe some pics would help explain it more
