this is my project that I want to share since these are very expensive to buy. My goal was to build a cheap and very portable pontoon system that will work with most kayaks with these style of fishing rod holders.
Step 2: Pontoon Mold
-make the mold using foam board.
cut the pieces and assemble as seen in the images*
*note size is not shown because these are more of a guide to help make them and the size varies from factors such as weight of person.
Step 3: Line Mold
-use a heavy garbage bag to line the mold to make the extraction easy.
Step 4: Pontoon Pole
to build the pole you will need a labout a 2-3ft piece of 3/4 inch pipe and a thick dowel.
-drill a hole the size of the dowel in the pvc and insert the dowel like the image shows.
Step 5: Foaming It Up
Each pontoon uses two cans of foam.
-place the pole in the center and use a foam board to hold the pole center while you fill the mold with foam aswell as while it cures.
Step 6: Booms
Now while the foam dries take two pipes with a coupler end on one of them.
-drill a hole through the joint for the pin.
Step 7: Kayak Mount
To make the mount you will need two small pieces of 3/4 inch pvc and cut a hole into the large pipe lining up with the rod holders of the kayak.
-Insert the pvc tubes inside the pipe and line it up with there final placement and use a screw to secure the pvc to the large pipe.
-mark the bottom of the pvc and drill a hole for the pin that will hold the rig onto the kayak.
note-sorry about the lack of pictures for this step my phone messed up and corrupted the images from when I did these a few days ago.
Step 8: Attach the Pontoons
-once the pontoons have dried drill a hole for the pvc pipe of the pontoons
-insert the pontoons into the pipe and drill a hole throught the tubes using a drill bit that is suited the the size of bolt you choose to use.
- in the pvc pipe use the drill bit to add a few holes in other hieghts so you can adjust the placement of the pontoon in the water.
-insert the the bolt into the hole and secure it with a nut to secure the pontoon.
Step 9: Have Fun
-As you can see it works good even my usually skeptical dad even gave it a try.
-The unit very easy to set up and can easily be taken down and stored.
Step 10: Thanks for Checking My Project Out
If you like my project please let me know and help me out in the water contest .
-also sorry about my lack of exact sizes since this was meant to be a how to / basic guide and inspiration for anyone who has been wanting to make something like this for your kayak.
