Make sure that you have them completely straight and in line with each other when you attach t couplings.
Now cut 2 7" sections and slide those into the third part of the t couplings.
Look at your kayak and find which angle the ribs on the bottom are at. Take the last two t couplings and try to copy that angle. (If confused look at picture)
If you are not going to glue than hammer them
Step 4: Almost Done!
Cut 4 9" pieces of PVC pipe and stick them into the two T joints
Add the end caps to give a good look.
Stick two pieces of PVC pipe into the empty holes of the T joints and measure out 2.5" on each side. Then cut at the marking.
With the last two end caps drill a hole through the middle.
Attach the end caps with wholes in the end onto the PVC pipe.
Run the threaded pole through the PVC pipe and tighten nuts.
After that thread in a washer then the wheel then another washer then the end cap nut. Do this for the other side and YOUR DONE!
Step 6: Cool Extra Stuff
Paint your wheels! Take it apart and glue everything. Add rubber to help with traction.
8-21-13 I measured wrong I had to make my center beam longer and added pool noodles for extra traction.
