The eldest Grandie had a project for school, make an instrument, and an instrument that plays into the bargain.
Here he is giving Dad detailed instructions, some of those nails were a bit long and needed to be ground off.
What a wonderful project, he designed it all himself, drew the shape on the wood, sourced the struts and bands and only let Dad use the power saw to cut the timbers. Oh yes, and hold the nails to start the hammering. And there were no hammered fingers. Job very well done indeed.
