>How long does this procedure take you?? I think it took my son about three hours to clean out the old cords and replace with new. Overall, I would figure 6 to 8 hours to account for every procedure. Before the flanges are reconnected it's a good time to apply Teflon powder to the butts. In measuring spring tension, I didn't see much difference between an opened spring and one which was simply re-hooked. The un-tweaked spring had an angle between the arms slightly less than 90 and still had approx the 40/20 g tension. The spring which was opened had the approx same tension but when unhooked had an angle of about 90 but did exhibit a little more snap to the flange when flicked. So there's a minor benefit which is just above that warm fuzzy feeling of doing that little something extra, the psycho-mechanical aspect. -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
