Well I employed a much simpler set-up:
I also padded the sharp metal edge with a split piece of clear plastic tubing, and for the clamping I am using two stainless steel pipe clamps. The big plus here is that it doesn't look nearly as bad as the huge c-clamp and it doesn't impede the other functionality of the Rocky (such as seeing the number dial). I am also pleased that I could achieve a stepless design at little cost, with an easy to implement mod that is completely reversible and of which should not damage the grinder or it's parts. Everything seems to be padded and covered, and I must say this mod works like a charm. Adjustments are made by simply turning the hopper with both hands. That works surprising well because since the hopper is always under a rigid hold it turns smoothly and even very small adjustments are easy (it's tough to overshoot in other words). The force needed to hold the hopper completely still during grinding is less that the force needed to adjust the hopper, so I can make adjustments on the fly without having to loosen the clamps, a big plus! It's great having a stepless Rocky Doserless.
Also as I mentioned above the big perk of this mod is the fact the hopper (and thus top burr) are held in a very rigid arrangement something I didn't see much in others mods. It seems (based on one days tests...about 9 doubles) that the grind seems to be even more uniform. The grind does not drift under load and I suspect that because the hopper is held so firmly (much more so than the standard spring loaded pin) that it results in a more rigid grinding system.
All I know is that my shots today blew me away with a noticeable better taste. Less bitters and a cleaner more defined flavor (it's really nice not having to use steps). Plus if I need to grind for drip I can simply loosen the pipe clamps and bam, I have a stock Rocky grinder!
I couldn't be happier with this set-up and I feel as if my need
to upgrade just got pushed way back! Take a look:
