Good to see you have the spinners you want comming. I was just wondering how much foot pound force you think you are setting your spinners on the spindle with ? When I set my spinners with my hammer, I hold my hand right at the head of the hammer. So I'm probbally not setting more than 50 to 80 lbs total. I strike until the rim is set & then one or two more strikes, but only that force that the close hammer head hold position will provide. Then the safety wire! I've seen suggestions that 300' lbs is recomended, but IMO that is extreme. But I usually set my spinners @ 80' lbs with a homemade spinner tool & torque wrench. At least I can remove them if need be when on the road w/out any problem. My spinners are Alum. Well, hopefully the new spinners will solve your problems. Good Luck
