rickbrad, I do mine like MinnFlyer but use epoxy. Force a few drops in the tube with your push rod, spin it around to get it wet all the way. I try to get it in about 4 inches. I do this at both ends so I can use Z bends at the servos. If you don't want to see the ugly yellow tube, cut it so at max push it stops at the fuse edge. Also put a pinhole in the tube some where for a vent. I have some of these that are about 20 years old and you still cannot separate them.
Thanks Minnflyer, I never considered using CA. Think I'll give it a try.
