Gooseneck Base
Gosh , I am making a similar gooseneck base out of a solid aluminum block, and plan to attach it to the mast with 8 ea FH 1/4" SS machine screws. These spaced at least 7 diameters apart, or more.
I am hoping to counter-act side loads, by machining a verticle rib that fits into the sail track
Was it Nigel Calder's book that says welding structural fittings to a mast distroy's the temper of the mast and welded parts in that area ?
He commented about welding on spreader bases, with the welds going half way around the mast wall on each side .
So with this in mind, I have fabricated a complete mast and it's fittings , without welding anywhere , and mostly because competent welders in my area, are too expensive or not available.
