http://picasaweb.google.com/USViking/VictoryLake#slideshow/5485005370171100386Have probably done 5o adjustments on the fin, always in search for a consistent offside The ski would rock for me, then my 2B's would start to fall apart. All leading to trying many different fin dimensions. Became increasingly curious as to why it seemed the depth always was greater at each re-adjust; blamed it on poor measuring technique in the hot sun. Today checked depth after each set. 1 short set, it deepened .002, 1 long set it increased from 2.512 to 2.517, loosened the clamp, knocked it back up in the block and it was back at 2.512. Took the block & fin off the ski, held the fin block halves together containing the fin, pressed by hand, the front was holding the fin, but the back not contacting the rear tab of the fin at all, not even after tightening the rear clamp hex screw, could pull the back of the fin right out easily Turns out the rear DFT set screw when placed forward past the threaded portion of the block into the recess bored out in the clamping halves was preventing the rear portion of the mating surfaces of the clamp from contacting the rear fin tab. After removing the rear set screw, the problem was solved, DFT easy enough to adjust in its absence. This would explain why in my sets I would keep getting wider & earlier into 2B (LFF) but having progressively broader turns and fighting for 3B. Looking forward to getting back some conistency. Never had a problem like this with any D3 fin block, it didn't seem to be a problem when running the fin further back & much shallower. Have been preferring of late, 2.510/6.898/.742/8(back) or at least for the first pass or two.http://picasaweb.google.com/USViking/VictoryLake#slideshow/5485005370171100386
