Downweight-upweight divided by two gives you friction. You probably don't have frictional problems but the good old weight problem. If you have a heavy downweight (60+ grams) and plenty of upweight (30+ grams) you can safely remove weight from the hammer. 1 gram of hammer weight=5 grams less grams at key including upweight. Question...is the upweight at a 5 to 1 ratio?
