I've got sensitive scales, but nothing for horizontal forces----I needed to measure side force on a phonograph arm--to cheap and lazy to go shopping (for anything)

So: attach an old hacksaw blade to a scrap of wood, install a scale, and there you are. The photo show the super-precise calibration setup---push down on the white scale tab to get the higher forces. It's probably good to 10% over a range of 10 to 70 or 80 grams. I need ~25, so that's the only calibration so far.
