How to make a locking ball stretcher

[danfurbiss]

I recently purchased a chastity device, and have been wearing for a few months on and off. I got into chastity to feel like I have no escape, but I have found that I can relatively easily slip out of my current device. I thought about ways to prevent this, and I remembered ball stretchers. I have yet to find a locking one, so I have decided to make my own.

I though about getting some schedule 20 PVC pipe, cutting of a ring of it, then cutting that ring in half, and putting a hinge on one side and some holes on the other to lock it in place. Any other ideas?

Something else to try is making your device smaller. If you're able to pull your balls out with the cage locked on, the A ring is too large of a diameter, or there's too much of a gap between the cage and the ring.
