removing cam pulleys

Hey guys, I was out in the garage pondering how to break loose the bolts on the cam pulleys and I think I came up with a slick way to break them loose. Before you take the timing belt off, put a 17mm wrench on one pulley bolt and put your big cheater type 17mm socket on the other pulley bolt and rotate things until the wrench on one pulley is jammed against something solid. (I used a cheater against the floor) Then break loose the first bolt. Reverse the procedure for the other bolt. This will retighten the one you just broke loose but it won't be nearly as tight. Go back to the bolt you just retightened and put the wrench on it and smack the wrench with a soft hammer. Viola! Both bolts broken loose and no damage to the cam pulleys. Sometimes I have these brief moments of clarity.
