This is a quick instructable on how I make my Kraft paper tubes for my homemade motors. These are only parallel rolled, but you can use a similar method to make spiral tubes as well. Sorry for the poor quality of the images and lighting. I don't have a proper lighting or tripod setup as of yet. The images will be updated at a later date.

  • Kraft paper ( local newsagent or craft store )
  • Glue or Glue Mix - 1 part water, 4 parts wood glue or craft glue
  • Wooden dowel - 7cm length
  • Scissors or sharp blade
  • Sandpaper of light strength

Step 1: Take a look

Here are an example of the tubes in action after filling with bentonite clay nozzle mix and black powder single grain fuel. Below you can see a movie of it in action as well.


<p>This is great, I will try this in the next few weeks when I get a chance. question, did you ever get around to building the parallel tube machine aspect of this? <br><br>Also, how does this compare to the strength of say an estes or quest rocket motor casing?</p>
Hello and thanks for commenting :) If you look up how to make wire springs, you will be able to figure out how to make a paper winder, using the same simple technique. I could have a go at making one to show you but may take a little while :)
Looks good! Thanks for posting!
