GoPro Mast for kayaks

myminifactory

Print and assemble to get a sturdy post to fix a GoPro camera in the back of your kayak to film yourself while paddling. This version requires a 16mm OD/15mm ID tube- I use a low cost curtain tube from the hardware store. The Mast tip and Mast End are inserted on either end of the tube. They should be a tight fit - I use a block of soft wood and hammer to drive them in. You may need to file or heat the cylindrical ends of those 2 pieces to fit into the tube without destroying them. You can also drill a small hole in the side of the tube to drive a small 3mm screw and lock those parts to the tube. That tube is then inserted and attached using a 1/4in screw (1/4-20) - use inox if available. A J bolt plus nut is used to fix the mast to the rear handle of your kayak. Fix your GoPro to the top and go paddle. Back-rolls are not recommended with the mast attached. If you hit something while paddling or when upside down, the mast tip is built to break hopefully before the Gopro casing. This will send your Gopro on its merry way - better have a leash or a float to recover your expensive Gopro.You would be surprised to know how many Gopro are laying at the bottom of popular white water rivers.   Hardware I use: - M5-30 SSteel Hex head, for the Gopro hinge- M5 nut- 1/4"-20 x 1.125" Steel screw, to attach the mast to the dome- 5/16"-18 J bolt 5in long- 5/16" nut
