Better EC12 A Frame Mast Jig. Used to ensure EC12 mast is vertically centered across the beam. Another day, another (3D printed) Better EC12 A Frame Mast Jig.
Watched a clip on SailWars! with Jarl Wathne using a wooden A Frame Mast Jig to ensure EC12 mast centering in vertical axis.
Created and printed a 3D A frame jig that uses 6.65mm diameter fiberglass rods (driveway edge marker rods) as the legs and a 24mm x 3mm cap head bolt as the pivot point. Two nuts and a lock washer are fastened with ~2mm of bolt protrusion. The cap head bolt is recessed on the forward side of the starboard top part with the excess length protruding towards the stern. With the mast raised the jig is positions on the EC12. The ~2mm bolt protrusion should contact the centerline of the mast when the mast is centered between port and starboard and not leaning to the port or starboard due to unbalanced shroud tensions.
Model is comprised of four parts 3D parts of a port top, a starboard top, and two bases.
