I’ve designed some nylon mast plugs based on the engineering extrusion information I’ve obtained for the standard Sabre mast (as a side note the tolerances on the extrusion we use are +/- 1.5mm!).
I’m having them made on a CNC mill which means I need to put in a minimum order.
Anyone need a set of mast plugs? Drop me a line (greg at whitetan.net).
