Hmmmm, just found this thread. You guys are great ...love this modding and mechanical geeky stuff, it's so me!

Great write up replete with pics, not to mention the mod to the mod; very cool gents!
FWIW, I think I'd rather keep the slower (stock) speed as it doesn't really affect my time much and arguably offers more control over what the string/string post is doing. At $9, I don' think I can miss! Going to look for this at my local wallymart ...thanks for the hot tip!
But...can I see what you use for the head that contacts the tuning keys?
