Hello Everyone, I was working on my 1948 or so Westinghouse LivelyAire today and was trying to get the blade assembly off so I can try and figure out why the fan makes a nasty rattling noise when it starts up and I can't seem to get the setscrew to come loose, and its a standard blade setscrew which isn't stripped it still has plenty of the head left to put a bit into but when I go to try and turn the setscrew the screwdriver just slips out of the setscrew head as if the screw's head is stripped but it isn't and the screw just won't budge even with heat applied to it and there isn't any rust or anything because the blade is in pristine condition, just a little oil and grease build up around the setscrew hole area but that's not what's making the setscrew not budge. 
Anyone else have any issues with their setscrew for their blade assembly on their LivelyAire fan when they were disassembling their LivelyAire? If so what did you do to get the setscrew out?

Any help with this matter would be appreciated.

Thanks,

Levi

Try tapping the top surface of the slotted setscrew with a hammer to "unmushroom" the slots in the screw.  Gently and watch what you are doing.  Then use a GUNSMITHS screwdriver or similar that fits well in the slot.  Add a good penetrant such as KROIL.   Give some pretty good, heavy torque to the screw and HOLD THE TORQUE on the screw.   Let loose the torque and apply it again.   Then torque the screw to TIGHTEN them loosen, back and forth and with heat.   It should let loose in a while.  The secret is to not let the screwdriver slip from the slot and damage the slot more.

Well the only problem is that the only kind of hammer I have is a 10 lb hammer and its too big to go inside the cage of the fan to hit the top of the setscrew. 
Also I don't own any gunsmithing screwdrivers and nor do I know where to get any.
Also I've tried using penetrating oil on the setscrew previously and that didn't seem to help much and I tried to put as much torque into turning the setscrew as possible and that ended up making the screwdriver bit slip out of the head every single time. 

because the way these LivelyAires are made with the cage removal dependant on the removal of the blade I have to use an extension bit with a standard bit attachment attached to the extension bit to even reach the setscrew from outside the cage. 
I have some really nice carbon steel screwdrivers that I picked up at Aldi 6 years ago but the bits are either too big or too small and the shaft and handle of the screwdrivers are either too short or are long enough but too big of bit to fit the screw head.

Also as I said heat didn't seem to make a difference in whether or not the screw would break loose or not, and I was using one of those mini butane torches used in heat shrinking and soldering.

Get a long screw driver and grind the blade to fit.
you might have to get a piece of steel round or square and make  your own screw driver.
how good are your blades  they tend to crack  near the center where  the blades come  down to the shaft .
 Good luck

Perhaps you should get a smaller hammer:light: You can get them at a local hardware. They come in different sizes:up:

Ace Hardware has a great selection of screwdrivers.

To hammer the top of the screw slot to help "close in" the tops of the slot you can use a long punch, the end of a socket extension(s) or a long piece of rod or other metal.   You are not going to be hammering hard, just tapping.

Ok, thanks. There are a couple of gun shops near me, I'll see if I can stop by one and get some screwdrivers from there.

Take your fan in case you can buy single screwdrivers and not a whole set.   Some blades will be more useful for fans than others.
