Bill, you got me thinking. The Vari-grind 2 base does have a very small amount of movement in the u opening at the top of the base, but I'm unsure if this is causes any problems. Nonetheless, it wouldn't cost much to add small piece of plastic tubing (i.e ice maker plastic water line split lengthwise) around the U opening to tighten it up.

Thanks for the remind about catches.
