This is what a self-sealing stembolt actually is

This is what a self-sealing stembolt actually is

A 'stem bolt' is most commonly the bolt that holds a bicycle stem on, which is the part that clamps onto the handlebars. A 'self sealing' bolt would have a nylon collar or gasket under the head of the bolt, presumably to hold in liquid or grease, or to help seal air or water from getting in. This is basically useless in terms of bicycle stems, but could theoretically help prevent water from getting into the stem and fork assembly.

I like to imagine that rom and jake were accidentally peddling (pedaling?) bicycle parts, and space cycling was a huge deal in that region.

Edit: come to think of it, do bicycles appear at any point in Star Trek at all? I seem to dimly remember that maybe Da Vinci has one in voyager?

Hello, i recieved a 'tested - working' MZ-920 from ebay. It came with a AA caddy which works. It powers off of AC fine. It came with a corroded gumstick inside the unit and some light visible corrosion inside the battery chamber, which i cleaned with contact cleaner. I have tried multiple gumsticks charged by an external charger and none are seen by the unit and it wont power off of any of them.

Are there any good repair guides for fixing this issue? I am pretty good with disassembly and reassembly of electronics but there are many small parts so i want to be cautious.

The good news is after I complained to the seller that he obviously did not test it with a corroded dead battery inside he is giving me to refund, id still like to get it working though.

Hi all, I have an extremely flaky remote that I just got (as a pleasant, unlisted bonus) from an ebay purchase of a MZ-N920. It does turn on with backlight, but left and right track seeking is unreliable, either skipping none or skipping 10 tracks at once. It also randomly turns off. I hit it with some contact cleaner to no effect. It is not obvious how to disassemble it, any success fixing these things in the past?
