Anyone rolling their own paper tubes?

Wow... i just did this today for a new project. Cause I'm a big rocketeer now so i don't have any BT20 laying around.
I taped the motors together with scotch tape, then wrapped them from one end to the other with one layer of packing tape. Use white glue on the kraft paper. Glue wont stick to the tape. The packing tape should be just enough thickness that it's not difficult to slide a motor into it.

This is about 6 layers.

Let us know how extracting that mandrel goes.

Not a problem to pull it out. I left it in because the tube will tend to shrink as it dries.
There is no glue on the inside layer (hopefully). The motors are wrapped with one layer of packing tape to provide a slightly-larger-than-motor inside diameter. Any glue that might have seeped into the inside won't stick to the tape.
