Default Paper Servo Lead tube for in wing

Looking for a source of paper tubes with a 1/2" diameter to install in a wing to run servo leads in.

Thanks

Ron

wrap a section of pool cue in suran wrap, then add two layers of typing paper with Elmer's white glue...... thin....adjust so you can slide it off when dry.

Other than soda straws, I used to see paper tubes in big boxes as once used for insulating bare wire purposes at a local electronic swap meet. This system is obsolete today considering what is available in insulated wires.

Problem being is these swap meets seem to be getting fewer and fewer.

I make my own with plain paper and a few drops of CA.

For a built up wing, I drill holes through all the ribs that the tube will pass through, roll the paper up and slip it through the holes, then let it unroll until it is snug and add a few drops of thin CA.

For a foam wing, I will roll the tube and hold it with a couple of pieces of tape and then glue it.

There are lots of ways to do it, just look around your house and see what you have handy.

I'd just roll my own out of writing paper and use some clear adhesive tape as already suggested.

But if you really must get something commercial then the rocket body tubes from Estes are out there.

I do:

Roll my own from paper sheets. Rarely glue them, and usuallyjsut a turn or two... Just leave then tight, slip them into the holes, and let them 'expand' on their own. Then add a drop or two of CA onto the tube / rib connction. (This way, you have a tube that fits exactly, the holes in the ribs..)

There are many rocketry vendors who sell just tubes. Probably a 'BT-5' is best (0.511" ID) and typically come in 17" to 36" lengths.

If you want bulk: http://www.euclidspiral.com/tubing/e...-products.html
(and if you're lookign for Kapton, Nomex, milar, etc...)

Thanks to all who responded, Picked up some 22" x 34" paper at work and will cut to the length needed and do as mentioned above.

Thanks Again
