These last two posts refer to whippen/key leverage. You can tilt the action changing the whippen felt to capstan contact point which will change touchweight. On Baldwins and other brands where the action sits on thinner posts, you can actually bend the post front to back changing the leverage. We're talking slight. This works. However, on the Yamaha's this is impossible (short thick stubby screw on a wooden base) without removing the post and the wooden base it sits on (filling screw holes and redrilling) and repositioning the base itself in new screw location. This process makes it hard to experiment with different positions. Again, it works. By tilting the botton of the action away from the key the action is heavier..like pushing someone further out on a seesaw. But we're not talking much, keep an eye on whippen felt to capstan contact through the stroke and consider wear, etc. I do not believe this affects repetition. The solder idea has worked well, too. Have fun, but be cautious!

Would you think this to be a bad idea? It wouldn´t have to be really tipped or anything but I wonder if this would increase the wear and tear on the overlying felt.
