I would add that the key dip before contacting the string should be the same for all the notes. I would not be without a screw adjuster. It is much more accurate than a chop saw. Also it helps stop the jack hanging. It also means that the jacks can be pre cut to the same length. Very interesting video.
When using a chop saw and taking off small amounts, it is useful to push the piece against the blade not rotating, and then raise the blade and push the piece over the required amount. Harpsichords move with time and changes of temperature and humidity. The screw is ideal for compensating. Much better than chopping or shimming. The bentside treble end tends to dip with time under the string tension. Look at any historic harpsichord. Jacks are expensive.
@@mtr369I’m just sorting the same process on a virginal. I’ll see how even the touch works out without screw adjusters. I suspect I will want to add them later. Wooden jacks can be sanded to a perfect fit in the register slots.
