Rupert has done a number of conversions. He mentioned that he had to shim (only) one. Removing the drive pulley and loosening the motor a bit to install a shim is no big deal. When reassembled with the shim, check to see if it runs better or worse (or the same). Adjust accordingly. Once you get it tuned, it should remain in tune. I suppose belt grinders are like homo sapiens, all the same species, but not identical.

ps Many years ago, I shopped for a Steinway grand piano. I was surprised with the difference in tone and touch of same model pianos. If Steinways vary, why shouldn’t Viels?
