Gary - I'd suggest that removable hinge pins are not the best way to go, because you widen the gap considerably.  You'll still have to seal the gap with tape, but the wider gap increases the chance for the tape to get too far down into the gap and foul the hinge barrels with mastic.  If the tape sticks to the hinges, increased control 'stickiness' results.  So my first choice is to either go with over and under cloth hinges.  About an ounce lighter than nylon, and if you run them tip to tip, self sealing.  If you use barrel hinges, the trim colors are easier to paint across the gap.  Try cutting inlays into the trailing surface to minimize the gap and bury the hinge inside the movable surface to avoid tape fouling.   I pull the hinge pins and substitute sewing pins at least 5 thou thinner than the stock pins, with the end bent over and stuck into the fixed surface alongside the hinge body  Prevents misalignment from binding up the controls.  Tom H.
