I have an issue with the light poles available to kayak anglers for mounting 360 degree lights. They are too short to be seen above the paddler. And they usually need a Scotty mount or the likes to hold them. I use a crate with rod holders mounted to it. I wanted a light pole that would fit snugly into the rod holder and be high enough to be seen over my head.
I happen to have a piece of 3/4" pvc pipe that I started designing around. My first attempt just used the 3/4" pvc pipe but it wobbled around inside the rod holder and it was too high. I had to really reach to turn it on and off or to charge up glow plastics. So I went to Lowe's with the rod holder and found a solution that would work.
So here is the parts list and photos of the construction.
24" 3/4 pvc pipe
12" 1 1/4 pvc pipe
1 3/4" pvc cap
1 1" pvc plug
1 1" to 3/4" bushing
1 1" Chair tip
machine screw & fender washer or lock washer
360 degree light w/ suction cup mount ( I'm using one made by Teklite and sold by REI under the Paddlers Supply label)
First, glue a cap on one end of the 24" length of 3/4" pvc pipe and the bushing on the other end using pvc primer & cement
Second, using Gorilla Glue, because it expands and the following connections are not tight fits, glue the plug into one end of the 12" section of 1 1/4" pvc pipe and then the bushing end of the 3'4" post. And allow to dry. It is going to be very difficult to get it straight so don't worry about it.
Then slip the chair tip over the cap end of the 3/4" post ( the top of the light pole) and then drill a small hole through it and the cap.
Remove the end cap from the suction cup mount of flashlight. Remove the bolt inside it. Replace it with a machine screw with a washer under the head. Make a small cord loop and double wrapp it around the screw and then screw into the hole drilled on top of the pole. Screw it down tight because it is rubber to rubber and has the cord under it too.
And it is done. Place the pole in the rod holder and the flashlight in the end cap and tether the light to the cord loop.
