Those are not ordinary fender washers they supply with the PR. They are about 3/16" thick, and 2 3/8" diameter. As in the graphic- those weighed a range of 65-67g per disc, so they are not light either. 3x 1.5" zinc fender washers from the average hardware store at 1/16" thickness, and then the lock-wingnut. You can use thread locker and a lock washer instead if you so choose, but the wingnut holds well in my case.

I did not weigh the entire mass myself, as it was measured to hit my tuning and not the mass required. I would strongly suggest you measure the tuning if at all possible. There is bound to be unit to unit variation in actual Mms of the PR itself without mass attached.

Later,
Wolf
