since y'all asked...
OK here's some more pics. First though, I almost thought that same comment about "I'd rather just have cold hands" myself. Mine & the satellite dish guards do look kinda fugly. But I also remember well the feeling of being miles from home and MISERABLE with frozen digits. At that point I'da given anything for some ugly a** hand guards. ha
So anyway, DISCLAIMER: I made these to be single-use, throw-away since I rarely take long winter rides. But me and some buddies from work are riding from ATL to ORL next weekend for a work conference and I don't have heated gear. So yeah... these are pretty crappy, but should suffice.
On both sides I just zip tied the trash can halves to whatever seemed sturdy to keep them from moving around, and I'm relying on the natural convex shape keep them rigid (no brackets or braces). Pics attached. NTOE: on picture L2, you actually can't see the zip tie but it's snuggly securing the plastic to the metail choke cable guide which seems really sturdy.
