I started the prep for the fans. I know there is lots of documentation on the web on how to do it; I've included pictures from my prep for those who haven't seen it before.
First off, here's the before picture.
Here I am using my heat gun on the label, using enough heat for the edges to crinkle in but not completely melting it.
The label is now ready to be removed.
Start to pull the label away from the back, eventually removing it completely.
You can see that it leaves the back clean of sticker glue.
This is what you get when you have several dozen fans to do...
Now we need to remove the retaining clip holding the fan blade post on the bearings. It's the black metal ring with 2 "fingers", which in this picture are point down and right.
Now this clip easily can fly off while you are removing it, so I highly recommend you do it in a clear plastic bag so that when it does zip off somewhere the bag will catch it and you can find it.
You can see that the clip is pretty small, and if it goes flinging off somewhere it will be very difficult to find. Make sure you put these someplace safe; I am using a bunch of ziploc sandwich bags.
Next you can pull the fan blades off. Note the spring and it's orientation on the fan post.
Next remove the top bearing.
Don't forget to grab the bottom bearing. They are exactly the same so you can save them in the same bag/container.
We need to remove the motor. Luckily this is fairly easy, simply rotate the motor counter clockwise until the space on the motor aligns with the retaining notch.
Rotated counter clockwise.
Pull the motor up, and save the spring under it.
Now you have a clean frame, and don't need to tape off the motor during painting.
Next up we prep the fan blades for painting. You can see that I am using some Rust-oleum and painters tape.
Here I put two pieces of tape on the magnet area of the blades.
Then using a sharp knife I cut the tape against the farthest wall so that it leaves extra tape I can use later to cover the lip.
Now I remove the tape that was cutoff.
You can see it leaves extra tape which I then press down against the lip of the magnet area.
And here's the finished product, fan blades and frame are now ready for painting.
Only 39 fans left to go!A reminder to use the bag when putting the clip back on. It might fly off as you are pushing it on, and again you don't want to be trying to find it.
