Next phase of repair now underway

We have nearly completed the replacement of the defective, modern pinions, and this has freed me to turn my attention to the escapement.

When the clock escapement was converted from the original verge and foliot mechanism to the current, pendulum regulated one, the new escapement mechanism was assembled in a separate, upright frame that sits behind the clock. The mechanism is fixed to the frame by means of iron pins driven through the timber. Over time these have rusted and have split the wood.

Having taken the decision to to restore the clock to working order and return it to the castle, we have to accept that further corrosion is inevitable. To minimise this we are removing the iron fixings, cleaning them and reinstating them.
