but note that my ship's bell is in a drawer
Or roughly chew away at a wooden block using whatever tools are at hand
.......then tape a plastic bag to the mast - and then offer up the wooden block coated with thickened Epoxy
(no dripping!) to make the perfect fit
........having a rough finish inside the curve is now a good thing
.........either stand holding it until set
or use a bit of elastic to do the same........bound to be a bit of sandpapering edges required afterwards, but the more excess Epoxy
you can wipe away when still wet the easier that will be.
Obviously make sure that no holes in the plastic bag............
......and do not scratch nose until Epoxy all cleaned up.
