railblaza kayak light pole adapter for 3/4" OD Aluminum pipe

thingiverse

I designed this adapter specifically to accommodate my Shoreline Marine Kayak LED Stern Light Navigation Light with Strobe, model # SL92001, by mounting it securely on a length of 3/4-inch pipe, whether aluminum, PVC or ABS. Given that the length can put excessive stress on the base, I engineered the adapter to utilize a 2-inch 1/4x20 bolt and nut through its center, effectively increasing its strength. The pole is held firmly in place by a #8-32 cross bolt, while a lock nut ensures that it stays put without requiring any crushing of the adapter or pipe, thanks to the nylon's locking properties. The holes for the lock nut are positioned 20mm from the end on center and drilled with a 3/16-inch drillbit. I also secured the light at the top of the pipe using a steel wire lock pin. UPDATE: After experiencing two adapter failures while attempting to switch on the light, I have since created an alternative adapter for use with 3/4-inch ID PVC EMT pipe.
