Introduction: Simple Foldable Kayak Trolley in 20 Minutes
A simple kayak trolley, made in PVC tubing. Easily to disassembly for transportation.
It is lightweight and fits perfectly an Ocean Kayak Malibu II sit-on-top kayak. If you have a different kayak, only need to adjust the distance between holes in the frame to make it fit.
Enjoy it ;-)
Step 1: Materials
Two wheels (recycled from an old lawn mower)
PVC pipes: 75 and 37 mm of diameter, about 1 meter of each one
2 screws with nut (M8x110mm) used as wheel axle
2 screws with nut (M6x80mm) to join the PVC pipes in a frame
Total cost of project: near 0 (just some cents to buy the screws)
Step 2: Tools
38mm drill crown
8mm drill bit
6mm drill bit
Step 3: The Parts
Cut 1 piece of 75mm pipe. For my kayak it was 540mm in length.
Cut 2 pieces of 37mm pipe, one for each wheel. In this instructable they are 420mm in length.
Dimensions and holes needed are shown in next step pictures.
Step 4: Assembly
The holes in 75mm pipe are 38mm diameter. The centre of each hole is 44mm from each side. The distance between holes is 410mm that is the distance between scupper holes in the cockpit of the kayak. Also will need 6mm holes located perpendicularly to 38mm holes (and also 44mm from side).
At 25mm from the side of 37mm pipe, make a hole of 8mm. Use M8 x 110mm screws to attach the wheels to the pipes.
M6 x 80mm screws are located as shown in the figure to join the three pipes. The distance of the hole is 200mm from wheel side, and it has to be made perpendicularly to 8mm hole. It gives 220mm of tube that you have to pass through scupper holes in the kayak.
If you have a different model of kayak, probably you will have to change the distance between 38mm holes, to make them fit scupper holes of your kayak.
Step 5: The Result
Here is what you get, a simple trolley to move easily your kayak.
Step 6: Folding the Kart
To fold the trolley, just remove M6x80mm screws, and insert 37mm PVC pipes inside 75mm pipe (as shown in figure).
Step 7: Others...
I have used polyethylene tubes inserted at the top of 37mm PVC tubes. This was for two reasons: to prevent sand or dust inside the tube, and to have some space to keep the screws safe when the trolley is disassembled.
My first design was made with aluminium, but finally I decided to use PVC tube which was lighter but hard enough for this project.
We have a be nice policy.
