We worked on the bell for the plastic trombone today.  First we printed a piece to make sure it would fit over the end of the pipe.  This files was then redesigned to fit over the pipe with a snug piece inside to prevent a sudden change in the inner diameter.  This file has a small flared bell.  It was left to print over night.  The next attempt of the bell will be even larger.


The form for the body of the tenor ukulele dried over night.  String was used to measure the length of the outer edge.  Pieces of baltic birch plywood were cut out and placed to soak in water for a couple of hours before being clamped to the form and left to dry.  There is a small gap at the bottom where the two side pieces should join which will have to be filled when the body is assembled.
