Hollowing the plates - part 1

Once the archings are perfectly finished on both plates, we can start the hollowing.

We use gouges to hollow and a measuring tool called a thicknessing calliper that tells us the exact thickness  of the plate at a particular point - hence the fact that we cannot re-work the top of the plates afterwards. We follow very precise measurements for thicknessing that we have refined with our experience from existing standard measurements.
