you can make the same adjustment by untwisting the cable and you can do that without a press, but you've got to use techniques. if you hold the riser in your hand below the grip with the string facing away from you, and grab the cable with the same hand you're holding the bow with and squeeze, you can stick something round or a fat allen wrench or two thru the cam and above the limb so that when you un-squeeze the cam can't rotate back. the tool should be pinned between the limb and the hole in the cam. this will take all the pressure off your cable and you can take the loop off the post and untwist it. this will time the cam, but maybe put you out of ata. but ata is really +/- 1/4" and so is brace height when the bow is bottomed out. OR you can just wait a week because you're package went out today (tuesday).
