George RR Fartin posted:Is there any reason they didn't make it so the crank was used via a ratcheting wheel attached to the engine so the motion of the engine didn't pull the crank along with it? Like, bicycles existed with freewheels at that point, so it would've been a known technology. They did ratchet, so you don't have a spinning handle once it started. The problem was when it swung back the other way. -e- I also think that ethanol was already a known anti-knock agent, but lead was pushed because you could patent it?

If it were to violently tighten (the engine starts), the wrench just starts ratcheting. If the bolt were to violently unscrew, it would turn the wrench and your hand.

If it violently tightened you would go for a ride as the gear is engaged to push that direction.

You know, I had never considered it, but I always thought that an electric starter was a small motor imitating the crank motion, I had no idea it was related to knocking

If the wrench is set to tighten then it prevents movement of the bolt counterclockwise

Right, sorry -- I didn't phrase that correctly. It's not that the electric starter caused the knocking, rather that the starter happened to first be offered on a car which sold well but had bad engine knock, which in turn brought Midgley into the picture.

Was about to say the same… I can’t think of any way a starter motor would cause an engine to knock just by existing… but maybe the starter motor only turned so fast and so they incidentally had to increase the the compression to make it work, idk But I’ve heard of same thing happening on old kickstart motorcycles. If you get a kickback it can break your leg. That’s why they say to always keep your leg bent and don’t lock your knee when using your weight to kickstart a bike. I remember pull starting our three wheelers when I was a kid and that thing could rip the cord out of your hand hard. Stung like hell in cold weather

Ah that makes more sense, as well as the coincidence later.

I once bought a 1949 seagrave firetruck at a scrapyard. It had a V12 Pierce arrow block from the 1930s that seagrave boughtthe rights to when PA died and used until the 50s. It had a hole in the grill and sure as poo poo behind the seat there was a crank. No I was not dumb enough to try crank starting it. Most crank start cars/ kick start motorcycles had manual timing adjustment to let you retard the ignition to prevent kickback. Motorcycles were particularly dangerous because a kickback could break your leg or make you faceplant into the ground.

I could see a chain of events going where hand-cranking meant you had to have pretty low compression engines, and with an electric starter you can raise the compression thereby having problems with knocking?

This is irritating because my very specific Monoprice-brand IP cameras work via ActiveX plugin that only loads in IE. They work so well still. My home server doesn't have enough CPU to do the motion detection and capture they're already doing in order to use something like motioneye (especially since each camera is already running motioneye).

Our IT department is doing everything in their power to maintain our internal database that can only run on IE... 9, I think? Despite having plenty of other platforms to move things to, including multiple that are already in use, because we "can't afford" the effort to switch over (read: they won't pay enough to have more than one developer). It's gonna get bad for them. It already is bad, but it'll get worse.

Xerox had their repair documentation in IE only and "unencrypted" it with an ActiveX plugin. That was like 10 years ago, but I found a crack video for this recently, so I'm guessing it might still be in use. Some of the smaller-end stuff was issued as a PDF, and we could still issue the bigger stuff as pdf, they just got unwieldy as hell. Flowcharts got too deep making it impossible to read anything. There were a couple task force groups created to get a new solution, but they would all get laid off after forming.

In the Tech Relics thread I was exceedingly happy with myself for getting a HDDVD/Bluray combo in my media server. Then in under 24 hours managed to brick it because the firmware update software compatibility stops at Vista and LOL not even compatibility mode works. Now this software runs and finds the drive fine and knows what firmware it has and what to update to. Not a single red flag, unless you click on a resources popup on LGs website. I have bricked TWO for the exact same thing. Humphreys posted:This is the second model of these drives I have bricked, but after a long night and a day of thinking and researching....
