well your soon know how good it is.
tbh my arches will prob never come off again, but incase they do ive done mine in a way they should undo easy.
i got dome nuts for mine, but think im gunna have too much thread hanging out to use them though.
no matter, ill be running some off that will fit when the lathe is up and running.
