Thought I would share a Twin Stick I'm building for myself.
The control panel (top of the twin stick) is cut by SendcutSend.com. They do a great job and I highly recommend them. This is 18 gauge, which you have to email them to request. Otherwise their website lists 16 gauge.
Inside controller is pad hack. Outside arcade stick is used Hori Saturn stick from Japan via eBay. Buttons and joystick are Seimitsu.
Buttons are 24mm screw-in, sticks are LS-33s, LB-30 balltop. Labels inside buttons are stickers from Amazon.com
Stock keypad is under mounted with the sides shaved so it fits flush. Make sure to leave the keypad centering pins and enough material to bolt to. Keypad uses stock overlays. I increased the hole size around the keypad from the first version of this controller so its less of a drop off than when the opening matched the size of the keypad. Also added little circle cutout to make it easier to remove overlay.
db15 connector is extended on several wires in order to make it to the cable exit port in the center back of the case.
Ribbon cable works very well to connect to buttons and joystick. Notice I reused the Jag's keypad pcb.
Most holes are countersunk using a drill. I do have a control panel overlay coming in the mail, but if someone wants to make a Total Carnage / Jaguar CPO that would be great to have printed. 280mm wide x 180mm tall would be perfect.
One Red button for Option, another for Pause. The right most red button is a second C button for bomb, makes it easier to hit while playing.
Going to try LS-62s, with LS-56 spring and Octal gate to see if improves control.
I'll be adding rapid fire, for use with Raiden.
