I didn't make any measurements whatsoever. That was dumb. With the next one -- and I have a few more to make for our fleet -- I'll make the slits smaller. I might cover the whole thing in rubber tape, but the copper is appealing, and that's what gives it the steampunk look. I suppose zip ties would hold on almost as well, and they're generally more acceptable on bikes than hose clamps, but that rule is rather arbitrary.

I've used silicone glue such as Shoe Goo, but how can I control it? It globs sloppily.
