Aha! Found the perfect replacement adjustment arm for this bicycle trainer! #BikeTooter #repair #kludge

Mother-in-law has a bunch of vise-grips she is trying to give away.

You make me think I can’t have too many vise-grips.

@AndrewHenry @ai6yr
Vise-grips are like duct tape: seductive but usually wrong. They can solve some immediate problems, but at the cost of long-term problems. That's fine if you're going to throw away the stuff you used them on when you're done, but you'll curse them later if you aren't.
@VATVSLPR @AndrewHenry So, how to fix this problem without vise grips 🤔

@ai6yr @AndrewHenry
You mean other than getting (or making) the actual right part? This may be one of the things vice-grips are good for: extending the life of something that would otherwise be useless. You don't care if you damage it, because the only other alternative is throwing it away.

The other thing they're good for is removing something like a rounded nut. You know you're going to throw it away once you get it off, so you don't really care if you damage it in the process. The key point is that vice-grips are most useful when the thing you're using them on is pretty much scrap anyway.

@VATVSLPR @AndrewHenry LOL looks like it's just a (missing) handle on the end of a bolt. i.e. essentially a fixed/permanent wrench.
@VATVSLPR @AndrewHenry new crank arm I guess needed at the end of this.
@ai6yr @AndrewHenry
Yeah, or you could get a bolt the same size (probably with a washer) and use a standard wrench on it. That looks like it was originally a standard bolt that had a cap with a crank arm attached. It looks like the original bolt head is still there, so you might be able to use that if you can remove the added widget on the end.
@VATVSLPR @AndrewHenry tried to add an arm, but needs to be attached to the bolt head. BUT, now I can use a standard wrench.
