    There are lots of designs for stills and there's no obvious reason to build this one. What was your inspiration? Why add a bunch of electronics? I'm asking as an EE, not a curmudgeon.

    Nice. Thanks for the reply.

    The results look fine. Can't see the water mark even when I'm looking. I'm working up to making a pair of derbys that are welted construction. There's a lot of new and it's hard to get started. It's encouraging to see your results.

    When stretching the leather over the last, did you wet it at all?

    Well, it's hard to argue that PVC is a good material, at least in terms of the environment. For me building will be relatively easy compared to convincing my family to use it! Keep up the good work.

    Such an interesting project. Saves water and energy. Why not just use some PVC pipe instead of an acrylic tube? Practicality is more important than maker-izing the project. Using LASER-cut parts really isn't required. And who wants a clear filter? Ew.Otherwise, really nice work. Concepts will work even for a less pretty version.

  • Yes, I think you can fix this. Won't look perfect but it'll be functional. I recommend sewing over glue. Nylon seems to work best. You can get foam from the craft store, too.

  • No argon. That was too high-tech for me, at the time. The air gap is optimized for dry air. Somewhere in the article I think I suggested desiccant but I didn't have a chance to try it out. That windows is in a house I sold, in a partially heated garage. It worked fine for that. But the real test of a double-glazed window is when the temperature difference is large, so don't take my experience too far.
