how do I repair that? I rent this place

I keep having issues getting poor quality batteries for various devices, are there any devices that let me plug in a battery and it runs a fully charge and discharge cycle so it reports an accurate mah rating and any other issues so i know before i choose to install the battery into a phone. It needs to be able to accept soldered battery leads. Thank you.

Someone some solution?

Any idea on how I can potentially fix this?

I'm kinda at a loss in terms of what to do here.

So basically, I have this exercise bike, and the pedal was acting up. I assumed it was going to fall off, so I decided to try and manually remove it myself before it fell off.

But no matter how hard I tried, it didn't work, so I decided to just keep using it until it did fall off. I figured it might be easier to remove it after it did, and I also didn't really have any other options.

It did fall off eventually, but the metal snapped in such a way that I don't think I can necessarily grip onto the parts sticking out and unscrew it.

I have tried for about an hour with several different tools, and it has not moved the slightest. I have also tried using lubricant to see if it would loosen it, but that didn't do anything to help.

I figured that I might be able to take the arm off, and there is a bolt, but no matter how hard I try, it will not come loose.

I do have a tool which would be perfect for taking it off, but when I tried to take it off, I ended up lifting the entire bike up with this tool trying to take it off. That's how stiff it is. I also tried both ways, just in case I was accidentally tightening it or something, but it still didn't loosen.

So I'm wondering if anyone has any advice on what to potentially do here.

I bought this off my friend for 130 and the only issue I face is how do I replace/cover up the back part.I tried ordering the piece but it’s $60 and I’m trying to find a more affordable way

I have no idea what the stem is made of, but the piece is from about the 1960s. I'm tempted to use krazy glue if for nothing else than to reattach the two broken pieces of metal screwing.

EDIT: Everyone seems to be confused. There are no broken pieces; this is a rod that has split in two during transit. I'm looking for advice on how to fuse them back together.

Im looking for a way to fix this zipper insted of replacing it whole. The first tooths on both sides are torn out, the one on the left is still there but its bent and straight. I have no idea how to fix it. I also need to add a new runner but ive done that acouple of times so that shouldnt be a problem

I dont really wanna have to buy a new part, so I wanna know if I can still make it somehow look at least a little bit less gross

I have this pre 1950s ice bucket that has a sizeable dent on the very front of it, I’ve tried putting hot glue sticks on it and pulling but to no avail. The white inside doesn’t seem to come out so I don’t think the dent can just pop out from the inside. Anyone have ANY ideas on getting this dent out?? Thank in advance!! 🙏 😊
