" Note ""
A little background:
While sitting in my tree stand today I slid my arrow in the rail track forward and backward. What I noticed was that it did not slide smoothly. There was significant chatter.
Upon close inspection I determine that the Lumenok was responsible for the rough chatter as the arrow slid in the rail track. Enhanced by the arrow retainers downward force or any extra applied downward pressure.
Solution:
What I determined to be the culprit causing the issue was the one of the metal contact wires on the Lumenok which was lined up with the upper inner edge of the rail track on one side. The sharp edge of metal contact wire was digging into the edge of the rail track.
So I gave the Lumenok a slight rotation in the arrow shaft which resulted in the arrow being able to slide smoothly in the rail track no matter how much downward pressure was applied.
Although this is a by chance occurrence due to the diameter / size of the metal contact wire and all the possible placements positions of the Lumenok insert when installed.
It is clearly a concern and can cause issues when the stars align as the saying goes.
Plus if left unnoticed it could after numerous shoots quite possibly cause damage to the inner contact surface of one of rail track edges.
So a as rule I will from now on align the metal contact wire with one of the vanes when installing a Lumenok which should prevent the either of the ( 2 ) contact wires from making contact with the rails inner edges.
Here is a picture of the Lumenok metal contact wire.
