Spreadsheet with cello hardware and workshop items
In the middle ages there were many kinds of stringed instrument that somewhat resembled the modern violin family. However during the 16th century several makers produced instruments with bass bar & sound post, and the modern violin family was born. The instruments of Stradivari, Guarneri & Amati are now consider the templates or standards for all that followed.

The laser cut templates used here help to produce alignment. However a basic method of construction is to leave extra wood in a few places until the pieces are brought together. Then they can be shaped & will match.
- The fingerboard is joined to the neck very early & guides shaping of the neck. Then it is removed, during finishing, and reattached.
- The back has an extra tab sticking out, the button. Extra material is left on the neck near the button. Then when all pieces are put together, the neck can be shaped to match the button.
Woodworking tools & techniques
Wood has some peculiarities that one must know in order to work without too many setbacks.
- Tools & keeping them sharp
- Grain & “cut downhill”
- Chisel or knife attacks from several directions
- Gluing: tight bond line, even pressure. PVA vs. hide glue

Patterns & construction notes for the templates. Probably only for hard core folks who want to set up at home.
