This is smaller of the two arcade sticks which I started building back on 2004, and will be finishing shortly (as of 07/18/2018). 
Happ Competition Joystick's were used in both of my arcade sticks. These were purchased in the early 00's and both contain actual nylon material on the actuators and joystick shafts.

This is my Arcade Stick which I built back on 4/17/04. 
I went with a Neo-Geo MVS Style, but it also works well with SF2 Fighters and everything else.

Final for now. I am thinking about making it look more like a traditional arcade stick. The wires make it look a little messy.

The hacked PS2 pad is encased in 2 SNES cart protectors. They now help protect the contacts etc.

Back that ass up!!

The bottom is made from heavy poster board and 8 rubber feet

 Arcade Stick prior to wiring.. Nice and neat :)
