After getting rid of my Cimbali Junior grinder, and waiting for my new Cimbali Max-Hybrid grinder to arrive, I pulled out my trusty Tranquilo, and have been using it for about a month. For fun, over the Christmas break, I decided to make a couple changes - one of which was to convert it to stepless. If you've got a Dremel tool, it's super simple to do.
The button that is pressed down to allow the adjusting collar to be turned has a small "nub" (for lack of a better word) that, when the button is released, engages the indents on the adjusting collar. I used the Dremel to grind this nub away. You're left with a small flat surface on which I stuck a piece of adhesive-backed rubber (I used the very thin stuff that is found on a sheet of rubber bumpers - between the bumpers). Now, when the button is released, it doesn't "look" for a indent - it simply presses against the underside of the adjusting collar, and the spring is pretty stiff.
I also put some plumber's tape on the upper-burr carrier threads. This removed any play (if there was any) and made it a smidge tougher to turn the adjusting collar. This additional resistance and the nubless setting-button, and, viola! Stepless. The whole operation may have taken 30 minutes, and it works like a charm.
With a couple mods, this really still is the bargain grinder.
