Helped the new owner beat his 27 together, last Sunday.............he looked shocked when I suggested he "taper" at least one pin. Nothing too severe, just 15 degrees and only on the part that extends out the back side of both spars. Found a 40mm pin in the barn from K-21 and it has 5 degree taper that starts an inch from the end, that sharpens to 15 degrees about 1/2" from the end. Looks professional, did Schleicher ever offer a tapered pin? Anything would be better than their blunt pin that will only start when everything is EXACTLY perfect!
