I am in the St. Louis area today (Monday) and wondered if there were any rotary engine plane builders in the area that I could visit?

   Maybe this is one of those things that isn't terribly obvious, but -
having used a variety of screw type clamps - I'm wondering why
plain old spring clamps aren't suitable for this application.  I can't
ever remember having one fail in service.  (photos below)

I think they are fine for small diameter hoses for little and/or low pressure.  I doubt they get the clamping force needed for coolant system pressures; so on a plane I wouldn’t trust them for even small hoses. The spring wire version concentrates the force on such a small area more likely to damage the hose.

That’s my opinion; I haven’t researched those clamps.
