Re: fiberglass flex fan
I've mentioned this before. I talked with the owner of Flex-a-lite some years back. Most problems were caused by owner misuse or installed incorrectly or owner tried to modify the fan by trimming the blades causing balance problems, using loc washers that gouged up/cracked the fiberglass, tightened down too tight etc. If you see these fans at swap meets ever notice how many 18" fans that have the ends gouged from hitting something???. Should of run a 17"!!
Also use common sense when running a used one. If it has cracks or gouges don't run it/buyit.
I will continue running mine with no sleep/worry problems whatsoever. A guy in my hometown, Jeff Ross runs an orange one on his '74 'cuda he bought new. Car runs in IHRA S/S class and won many class records in 2001/2002. Hasn't blown apart yet in 30 years.
