1 Virginal jack guide. Made up from a series of 12 mm (1/2") strips, slotted and glued. Can be purchased ready made.

2 Virginal guide top made up as in 1. Two of these, with sides, make a box guide identical in size to 1. Guide tops can also be purchased ready made.

3 Shows a strip of thin ply in which the slots have been drilled and filed to take the two rows of jacks. Not difficult to make but must be precise. Two are required, with sides, to make up the box.

4 A ready cut top for a harpsichord jack guide. Sides are glued to the top to brace it. A bottom guide also necessary but this can be a 'trellis' structure to take the lower ends of the two sets of jacks. See also 11 for a deeper guide for an Italian harpsichord, and also a similar guide for the Flemish harpsichord. The latter is cut from a solid strip of beech (traditionally fagus species).

5 Three types of tuning pins. The commonest is the 'zither' pin frequently used on many of these instruments.

6 Packets of balance rail (for keyboards), hitchrail, and bridge pins.

7 Round felt and paper punchings used to level keyboards.

8 Delrin (plastic) and wood jacks. The Delrin ones are manufactured. The wooden ones are made with a thicknesser, router, Dremel, and much patience! A jack tongue is shown adjacent and two pectra attached to a 'sow'. The latter is discarded.

9 A brass tangent which strikes the strings on a clavichord.

10 A key for the tuning pins.

11 Italian and Flemish harpsichord jack guides.

12 Stitched felts used in various parts of keyboard instruments.
