I would like to bush the time side main wheel of this 1840s circa Forestville weight driven movement but there is another hole next to it and if I use a bushing (Bergeon) that has an OD of 6.50mm it seems I will cut into (or come very close) the adjacent hole and it might not hold. Ideas?
I have no idea why the hole is there.
