Step 4 Finishing with Your Joystick

Now that the bowl and tubing fit into the top of your joystick housing, a hole needs to be cut out for the tube to continue it's journey. Truthfully I didn't measure anything here, but to be precise you need to cut about 3/16 of an inch down into either half to make the tube fit. As soon as you can get the whole piece to shut with your tubing inside you're good. The tube will end up getting bent when you piece the housing back together, so tinker with it a bit to make sure you can suck enough air through. Replace the screw that held the housing together and set the whole assembly aside.
