To create sheeting that is 54.5" long you need to join a 6.5" piece to a 48" sheet. I do this by holding the 48" sheet against a straight edge which is weighted down, and then edge glue the 6.5" piece. the I lightly sand from the small piece to the long piece (so I am pushing the joint closed). I also cut some pieces to be slightly longer than 6.5" so all of the joints are not at the same place. Does anyone have any other methods for doing this?
