should I put grease in these bearings? they’re not sealed. I have some pretty heavy silicone grease, is that good?
(There’s a little rust, it’s not bad, I’ll treat it.)
eta: I put in some silicone through the gaps and now I give the wheels a spin and they goes for like 30 seconds before I get bored and stop it by hand so that's pretty good I think. Thanks replyers!
@moira They look like sealed bearings to me, just not rubber seals. Grease is always a good idea when you can get at the bearings. If not just ride them until they fail or you get tired of the friction, and install new bearings. The surface rust is irrelevant.

Q4. The road bike I am now riding around town (1985 Dave Scott Ironman) has no reflectors or lights, and though I don't current go anywhere when it's dark, I am wondering what kind of additions the experienced here would recommend to improve safety on that front (or how to make it usable in darker conditions?) I'm using the bicycle for running errands...
I have a series of DVD-Rs from my dad. He says he recorded movies to them several years ago. Now they won't play in anything but the DVD player where they were created.
Sure enough, stick it into my laptop, it says it's blank.
What are my options here to extract data from it and into a video file? (Either Mac or Linux tooling available, Linux preferred.)
@Crell I wonder if they were recorded without being finalized. That would mean they were left in a state where more data could be added, but finalizing them later is possible in that case. wodim -fix might do it on linux. It's been a while since I've messed with DVD burning so I'm not sure if you should expect to see data on it without doing that but maybe someone else here knows. Best to try it on one that you don't care about very much.
Does your bicycle need a hug? I'm a retired bicycle mechanic ready to answer mechanical questions about most bicycles. I last worked in a bike shop in the 1990s and more recently I do charity work on bikes, so I am pretty good at coaching people through low cost repairs. I also know some things about indoor smart trainers. #RepairCafe#Cycling#BikeTooter#Zwift
@jnbhlr I use the Park Tool FT-4 to check alignment and securely hold the fork. It only supports 1" steer tubes. As long as the damage is minor then it should be safe to align it. Whatever method you use, you'll need to check if one blade is ahead of the other, lateral alignment in relation to the steer tube, spacing between the dropouts, and dropout alignment. A gauge or fork building jig helps limit the amount of bending and re-bending you do. https://www.parktool.com/en-us/product/fork-clamp-and-gauge-ft-4
@jnbhlr I also use a steel ruler to check if the steer tube is bent just above the fork crown. If it is I would usually replace the fork. Having one fork blade slightly longer than the other is also a fairly common manufacturing defect. If the difference is small enough I would file the inside of the dropout to correct it.
@jnbhlr Here's an example of a crude gauge that might give you some ideas. Also if the steerer is bent at the crown you can usually see that the crown race is not perfectly flat in the headset. https://www.youtube.com/watch?v=lx7BGBD0OdA
a month ago i went to a volunteer fair in my town and learned about a free community dinner and i've been cooking dishes for it every monday since. it's served outside where people live, not at a church, and i've really enjoyed incorporating it into my weekly routine. it's not that hard to cook an extra dish one night a week
Can any Networking Knowledgable types out there suggest why the old BT business hub routers I use for my little wifi network at work don't have usable wifi on my iPhone/iPad?
My MacBook is working just fine, but the other two just show "no internet connection".
It's not distance, the router is on my desk, 50cm away.
@DJDarren On the mac, hold down the option key and click on the WiFi icon in the menu bar. This should show you which protocol and channel it's using (under Known Network). Post a screenshot as it might help identify what's going on. Next question will be what configuration options are available on the BT devices.
