Reverse the direction of tying the second knot, the knots will lock each other. I'm concerned about using CA on the knot. The CA hardens and becomes a piece of hard plastic with sharp edges. If the knot gets into the windings, it may nick the rubber. I avoid silicon lubes because of the unknown effects on the human body; where does the silicon go and what does it do when it is absorbed into the skin?

I noticed you arer making your own washers out of DuBro Antenna Tube #511. Does that cut into the rubber?

[@FreeFlightDigest]

It generally isn't a problem
