Smear a dab of glue around the center of one of the straw
pieces and stick it in the bushing. Continue with more of the pieces, snugging
them up to one another as you go around in a circle. Using a tweezer to set the
pieces in the bushing helps ALOT.
Keep going until you complete the circle and then go back and
adjust the pieces around to best fill the gaps.
Continue gluing and inserting pieces until the entire bushing
is filled with straws.Do your best while inserting to keep them parallel to the
sides of the bushing. When you're done with the straws, sight from the inside of
the bushing and check the alignment of the straws and move them around while the
glue is soft so that the light will exit the straws in a straight line (easier
seen than written about)
