After stuffing, I used my Dremel to rough up just the very end of the inside of the tube.
Bring the ends of the tube together and crimp the corners a bit with some small needle-nose pliers.
Open slightly and drop a bead of super glue.

Apply baking soda to any super glue showing at the seam.
This should have sealed it up pretty good. If not, scrape off any excess super glue/baking soda and sparingly run a thin bead of super glue and reapply baking soda. Just make sure it looks clean.

I cut the inside center of the cap out because it was positioned 1/3 of the way down the cap and would not allow for the cap to close completely.
I painstakingly carved a disk out with my Exacto-knife.
Once freed, I reglued the disk to the top of the cap. Position the disk and glue from the inside, using baking soda to strengthen.
Run a thin bead of super glue around the top of the cap too to fill any gaps visible from the outside. Once more with the baking soda to fill.

I used my Dremel tool to remove excess material from the inside of the cap. Remember, you will only need the bottom thread or two to attach the cap

I cut the top off of the cap *which works SO much easier if you heat the knife over a candle for a few seconds*
then I'm not understanding what I'm supposed to do with the little disk? and then how the cap would fit on anyway? maybe it's because I'm using a diferent brand *crest*
what do you think?
