Here are instructions for a home made Magic Tool:
You will need thick foam blocks (from a thick pair of foam sandals), an old credit card, and a set of bulldog paper clamps. Cut a straight slit in the foam blocks from end to end. The slit has to reach to both ends of the foam blocks to be able to release the fibers later.
Put the CDC fiber stems over the slit in the foam block and pull the fibers into the slit by their ends. If the plumes do not extend over the end of the block and cannot be pulled in, use the old credit card to push the CDC fiber stems into the slit.
Use the paper clamp in the place of the transparent Petitjean clamp to hold the end of the CDC plumes. Open the slit in the foam block to release the fibers and you are in business. The CDC fibers are lined up, cut off the stem(s) and place the fibers into the dubbing loop.
With this simple set of homemade and cheap bought tools you can do what the Magic Tool does. See the instructions below:
