Gardens' masts will sport caps, primarily as a decorative touch but also to better protect the wood end-grain at the top of each mast. The mizzenmast gets a collar, too. The caps are CVG DF and the collar for the mizzenmast is mahogany. A (rough) photo-essay of the process I used in creating the caps and the collar follows:
Eight segments with each end cut (on the table saw with a miter gauge) at 22.5°.
(Different) Segments assembled, glued (with thickened epoxy), and clamped.
Octagon blank ready for drilling (inside diameter begun), cutting (outside diameter), and sanding (all surfaces).
Top and bottom pieces of cap glued together with top piece cut/sanded to match outside diameter of bottom piece (could have used another photo or two here).
Top of cap will be sanded to "domish"/round-over shape. This is a practice piece.
Collar for the mizzenmast.
Collar and its base. The underside of the base is contoured to fit the aft deck.
