Yes! Original fans (two blade) are very dangerous. Four blade, not so much. But I still worry. The story with the two blades is that Henry made some errors here and there and the Model A two blade fan is one of them.. The blades are two pieces laminated together and as with most laminations, moisture gets between them and they rust from the inside out. You never see it. But you sure see it when the ole banger revs up and tosses a blade out through your hood. Really, they can be dangerous as heck! As Mike says, get a new aluminum ASAP. Right now, The only other really dangerous part on the car is the rear spring. These also are deadly. Do Not Attempt to Take one Off Without a Springspreader
Somewhere in the history of the model A, someone's been killed by this part! I don't know it for a fact, but I'm sure of it! I made a spring spreader out of 3/4 " pipe and ready rod. It twisted that pipe and 3/4 - 10 threaded rod and and sent a piece past my right leg at warp speed , had it hit me, I'd still be limping if I was lucky enough to save the leg. The best parts is, I was warned, but the old "How much can it be?" prevailed. To change the subject, There will be a swap meet in Rieglesville (Bucks Co) Nov 6,about the last for the year. Don't know how far is Mifflinburg, but I like this show. Plenty of people, but not crowded, just a friendly bunch of car lovers. Hope to see you and Spencer!
