Did you know Salsco came out with chain driven brushes this spring for HP11? The nice thing about their sprockets is they are split in two halves and bolt around the shaft so you don't have to take the whole drum apart. Their chain is not as beefy as yours.
I was ready to try do something like you did, but they had the ready to install chain driven brush kit available.
