Add the rubber band so you can fix the string when you roll it up on the coiler

You are done!

Time to test the tripod! Every camera has a different mount, so the bolt may or may not fit the exact depth of your bolt, but don't worry if it doesn't fit tight, it's not important for the stability of your tripod...

The image was shot at 1/2 a second exposure time at ISO 200 @ 28mm with the tripod – check out the 100% cut out from the center – pretty impressive! (Stability improves a lot if you place the camera against your forehead by using the eye viewer. Also using the self timer will prevent camera shake from pressing the exposure button...)

Use the tripod by standing on the string and pulling the camera upwards to make a tight triangle. This will stabilize the camera and make up for around 3 or 4 f-stops – enjoy!
