I have completed the bottom edge of the film holder frame. It's a small feat, but I have no idea what I'm doing so it is exciting to make any progress.
I cut the wood with the model saw to the lengths specified in the book. I then measured the alignment of each layer. Then I glued and clamped the layers together.
One thing I made sure to do is to remove all excess glue from the edge and more importantly the inside of the layers. Because these are where the sides will fit in, or where the plates will go later.
I labeled each piece with the length. I also labeled each piece of scrap as such. I know from past frame building experience how easy it is to get confused and cut the wrong piece, or glue the wrong thing.
It points out in the book that you will need to put scrap wood between the vice and the frame so it doesn't damage the wood.
I also used a piece of scrap as sort of a glue spreader in order to completely coat each piece. I didn't want any gaps.
