I made good on my intention to get restarted on the instrument making, and over this weekend glued up the back of the octave mandola. The two bookmatched pieces are only just big enough and I have have no spare at all. There may be enough for the 'button', but this might have to be made from a separate piece of figured walnut.
I also glued the tone bars to the yellow cedar belly. I had forgotten how quickly the Titebond glue sets and had to scrape some half set adhesive off the bars when I made a hash of it the first time through. With the bars its better to use too much glue to start with and squeeze out the excess. It was much better on the second attempt.
