Weighoff Kit

The Grandwork Weighoff Kit provides upweights from 20-25 grams in the first row. Note that all key balancing weights are accurate to the nearest tenth of a gram (i.e., 20.0, 21.0, etc according to my Ohaus CS200 digital scale). The second row has pairing weights either in 2g increments from 34g down to 24g or in 1g increments from 30g to 25g. Sliding the front row left or right provides pairing alignments that produce a consistent balanceweight or a consistent downweight, respectively. The middle setting offers either a 37g balanceweight or a consistent 50g downweight. The two weights in each pair (upweight on the bottom) add up to the downweight. Lift the pairing weight for upweight, return it for downweight. Add and subtract the pairing weight to compare speeds and place key weight on the key by trial-and-error until the speeds match.
