I decided to make a ball joint. I needed a way to attach my gadgets to the suction mount. I managed to buy the suction mount from http://www.crocsgripsuctioncups.co.za/ I must say I am super impressed with them and they are a lot cheaper than other suction mounts and I can attach whatever I want to them if I make the correct fitting.
So the first video is showing you my uses for the ball joint
The second video explains the process of making the ball joint. I have shared this on the Sealine Forum and got some great suggestions on a correct drill to use to do the counter sink.
