Michael are you into highly polished bevels? If so maybe additional glass or aluminum platens and more lapping films to fill down the progression, (3µ, 1.5µ and 1µ). You could add some more finer grit strops to fill down that progression, (2µ, 1µ, and 0.5µ).
You didn’t mention if you use a lighted magnified visual aid to see better what you’re doing. A USB microscope is a tremendously helpful tool. Especially when used in conjunction with a laptop computer. I wouldn’t want to sharpen without mine. It’s that helpful.
