- Temperature: I've seen posts about people having trouble maintaining temperature (having to frequently use the burners), calibration issues with the probes, and being able to make large temperature shifts. Hooch, I think I saw in one of your posts that you do a single step mash and go straight from your conversion temp up to ~168°F mash-out, is that right? Are you able to easily step up using just the RIMS, or do you have to direct fire the mash?
- Mods: I'm already brainstorming possible modifications, some simple, some approaching porcine aviation. Have any of you looked into automated gas valves & igniters, adding a whirlpool to the boil kettle, sparge deflectors or rotating sparge arms, or even a mash stirrer? (Yes, I've read that Sabco says "don't stir," but that was followed by "because you won't get consistent results," and an electric stirrer would be pretty consistent. But like I said, I'm just brainstorming here.) Has anyone attached a golf cart motor so they could drive the system around like an R/C car?
- Cleaning: I saw some people have rigged up CIP balls. Do they just use PBW with these, or can all the parts handle strong chemicals like caustic cleaners? I know (think?) earlier versions of the system used brass or copper in the RIMS tube, but it's all stainless now, correct?
