Ours was made an added this year during our third district event so we drilled a 1/4" hole, threw a long bolt through the lexan frame of the catapult, and used some round 1/2" OD 1/4" ID tubing from Vexpro as spacers. The frame was pretty rigid so we made the spacers have a slightly loose fit. Just enough to keep it steady but allowed it to pivot freely.
Had it been a made in our shop we might have used bushings or bearings as a pivot.
