The aileron control wires are 2-56 pushrods bent to form torque rods. They are coated with thick bearing grease and get buried in a mixture of epoxy and sawdust.
This gives a nice, slop free install.
I have used saw dust and epoxy as a filler were I needed some strength. But never as a sleeve for torque rods. Neat idea. The saw dust I used was what ever was in the shop from wood working projects. Sometimes I have added balsa saw dust , ends up much smoother.
I use plenty of torque rods but have always used metal tubing or plastic as sleaves.
Nifty idea. I will keep that one in the mental tool box.
