I don't think there are any videos, but here is my technique.
1. How many? When making tissue tubes, don't forget that the storage box needs as many as are on the model to fix the parts in the box. Then, you might have a wing bracing fixture which could need a couple. So be generous when making the tubes. Besides, you might want to discard the worst ones.
2. Materials. You should use a thin a tissue (not condenser paper) as possible. Esaki would be the paper of choice.
3. Grain. The grain should be along the tube, not around it. Strips are usually longer than the length of the tube, so the grain goes with the short side.
4. Size. The tubes can range in length, depending on the model type. For EZBs, something about 3/8" long is OK. For F1D and larger, 1/2" to 5/8" should do. I like to make four wraps, so the length of the strip should be about 13 times the diameter of the mandrel that the tube is made on (that's about 4*PI*D). A .060 mandrel would need a strip about 3/4" long. You can afford 6 wraps for Pennyplanes (19D).
5. Mandrel. The best that I have found use Teflon tubing over some straight music wire. If you can scrounge some Teflon tubing from an electronics assembly area, then hobby shop music wire will make a good core. The Teflon should be a solid fit on the wire. One size of Teflon can be forced over several sizes of wire.
6. Process. Now the fun part. Use full strength Duco cement. Run a very thin line of glue along one short edge of a strip. Only the tiniest line of glue is needed. Attach the strip to the Teflon, being sure it is square with the mandrel and the end of the strip is against the Teflon. Let it dry a minute or two. Then run a larger bead along the corner between the Teflon and the tissue and also down each side of the tissue about halfway to the end. Roll the strip onto the Teflon. You should have excess glue squeegee out. Keep rolling a few turns and then wipe off the excess glue from your fingers (pants or the other hand). Continue rolling until the outside glue is dry enough to keep the tube from spinning in your fingers and it slides on the mandrel. Then,as you continue turning the mandrel slowly slide the tube past the end of the mandrel, but not off of it completely. This is important, because you will crush the tube if it slide off. Of course, keep your fingers over the mandrel, not over the free end of the tube, or you will crush it. When about a quarter of the tube is left on the mandrel, use a fingernail to push the tube off. Let it drop onto the workbench and don't touch it for 1/2 hour or more.
A half-inch tube made this way will weigh about .0002 OZ (5.6 mg)or less.
