Just to make sure, is it okay for the propeller shielding to be soft so that if you pushed with enough force (more than a gentle poke) you could still touch the propeller?
I'm using a very thin and stretchable material and I'm not sure if it will earn a construction violation.
Has anyone ran into any issues using thin mesh-like material as shielding?
I think that will hinge on the supervisor's definition of the word "shielding." Clearly a thin, stretchable material can prevent a dowel from touching the propeller. I think, however, that the use of the word shielding specifically implies that the covering must protect users from accidental contact with the propeller. If I were the ES, I would apple the rule in that spirit.
If your covering resists (for example) a poke of a finger, then I would say you are fine. If I can poke it with my finger (or the dowel, which is really a simulated finger) and stretch it into the blades, you aren't really providing "shielding."
