Good afternoon, all, I decided to take a break from the ever-exciting world of sanding ribs over and over. I looked at the main mast bottom preparation, they call for a 90mm section to be shaped octagonally then transition into its 15mm round shape. All at the same time they call for outside diameter to remain constant in the octagon section which cannot happen as they drew it. Each vertex must occur slightly outside the radius, or one must cut into the mast to make the flat sides thus reducing the original diameter.
So, my solution was to create a faceted jacket glued to the dowel and trimed to fit. Yes, it will be slightly larger going through the deck, but I'll make it fit.
After scribing the layout on the dowel, I needed a proof of method so I made 8 pieces about an inch long to glue on and check the mate up. Youll see this first attempt I came up about 1.5mm too short.




The first strips I used were 5.5mm wide so I found some at 6mm wide and here is the result.




Second time worked great, after a little filler at the joints and final finish it should look fine. This type of work is really enjoyable, now back to the sanding dungeon.
Thanks for looking in.
