Re: Heat pump repair suggestions.

The Stanley part I mentioned as example is under $5 (you would need two) and hopefully it is already the correct length (3ft) so you don't even need to saw it.

Drilling the holes into aluminum should not be difficult. You may also want to pre-dill small holes for the sheetmetal screws (into the AC top cover) for best results. Just be careful not to drill or screw into the condenser coil!

And definately check the blade.

Are there any good/quick/easy DIY solutions for balancing a vibrating fan blade ?
When I replaced the fan motor on my own AC I also had to replace the fan blade since I couldn't get the old one off. The old one had a pair of metal clips presumably to balance the fan blade. The new one was sold to me "pre-balanced" without any clips and seems to be fine (very minor vibration).

Why not just MIG weld it?

That's what I would do.

First check I'd do is to set the blades down on a flat surface and make sure that all the blades touch the surface. Flip the whole thing around and check the other side too. This will ensure that none of the blades are bent out of alignment. If any of them are, you can bend them back to try to get them in-line with the other blades as much as possible.

You can also check that they are all about the same angle.

Another check you can do, is to balance the blades with a pen through the hub where the motor shaft would go. If any side of the blade set is heavier (out of balance), gravity will cause the blades to rotate so the heavier side is at the bottom.

If the blade set is well balanced, you can turn it to any position and it will stay put.

If the blades are heavier on one end, and you've checked that the alignment and angle of all the blades is the same, then you can attempt to balance it by grinding away a small amount of metal from the edge of the heavier blade (the one that settles at the bottom).

It's not the perfect method, but it generally works well enough.

I'd use aluminum angle over galvanized because when you drill the holes the rust will start there. so Al angle and a few stainless screws and you're good to go.

mixing metals is always a good idea.

I'd just use all steel and paint it.

How old is this sumbitch anyway? I'd get some large fender washers (like 1/4" X 2) and see how long they hold it.

After that, I'd call the manufacturer and see about getting a replacement top.
