Years ago, I got tennis elbow soon after buying a Radrunner. The pavement around here is bumpy. Each bump causes a sharp deceleration of the bike. You lurch against the bars. When I took my left hand off the bar to signal, I'd lurch against the right bar only, requiring tremendous torque with my...

I seem to recall them in Worcester MA in the 1950s. Worcester was unusual in that the neighborhoods were pockets between steep hills and lakes. Since the 17th Century, settlers couldn't choose their neighbors. We had a retired Anglo on one side, a French couple on the other, a young French...

[And Dick the shepherd blows his nail] They're never shown in ski gloves. [And Tom bears logs into the hall] How come they're never shown with a load of logs? Do they have Amazon deliver their firewood? [And Marian's nose looks red and raw] They never wear hats with extended bills to keep the...

A sharp blade cuts cleaner. That reduces my downtime scraping sappy pulp from under the deck. In the autumn, a sharp blade can cut leaves into bits small enough to disappear between the grass leaves. That saves raking.

Some consumer mower blades are soft enough to file. The first mower I bought was a commercial Lawnboy. Commercial mowers and many consumer mowers have blades tempered to HRC 38 to 45. Using a file to sharpen the blade was like trying to file a knife. I ended up using a stone. A 5" angle grinder...

This rum has a flavor I can't describe.

If the controller worked directly from the transistor pulse, you would often see PAS faults on startup. The KT controller used to work fine with the P14L. Six of the seven magnets still energize PAS at 10 RPM. The dead magnet explains the gap. If it had been dead before, I would have noticed...

My tube had been punctured by a hair-thin wire. The hole was so tiny that it wouldn't leak when I inflated the tube and held it under water, section by section. On the bike, it could hold pressure for a week of daily use, then go flat overnight. I knew Schrader valves had changed, somewhere...

Yes, the sensor sends pulses to the controller connector. But if the sensor happened to have a magnet close to the transistor when the controller was turned on, the bike would immediately take off with no pedal movement. I think the controller must pass the signal through a capacitor, to convert...

I didn't like files. They would get dull. I'd have to set things up so I could apply pressure, and it was too easy to rock. I came to prefer a 1750 rpm bench grinder, especially for bush hog blades. The stone scraped the steel at 45 mph. It could work if the stone wasn't too coarse and I kept...

I assume the pulses must pass through a capacitor in the controller. The capacitor would pass each rising and each falling pulse edge as a spike, a positive spike for rising and a negative one for falling. The voltage of a spike will depend on the steepness of the rise or fall. If the magnets...

By "missed shifts," I mean when I pushed the button to change PAS power, sometimes the controller and display wouldn't change. I used PAS and continued to use it with the KT. However, for the last 30 months, it has been my spare bike, ridden a few times a year to be sure it was in working order...

The 12-magnet replacement sensor arrived. It comes on at a cadence of 33. With my one-speed bike, that's 8 mph. Around here, that means PAS is not available much of the time. The original comes on at a cadence of 10, or 2.5 mph. I can guess why they're different. It would be dangerous for pedal...

My motorcycle mirrors were big and flat and up on stems. That's the kind bicycles once had. When i got an e-bike 6 years ago, I couldn't find any, so I got one that fit the end of my handlebar. A few minutes after I mounted it, I was on a quiet street when I heard the tires of a car close...

You started by saying metal to metal contacts must be kept clean: "So am I, but as an electrician we were always taught to keep metal to metal contacts clean and free of any contaminants." On that doctrine, you said anyone who greased before connecting was a fool. Doubletalk. You should...

Google AI found an opinion on a a forum for people who like Bose sound systems and the same opinion on a forum for people who like to put Pelican parts on Porsches. I wonder if they got their opinion from Google AI.

In the 1970s I kept a can of grease for wire nuts and terminal connections in 120/240 VAC wiring because the National Electrical Code required it in many cases. https://www.amazon.com/dp/B0CJ8ZYHV5 I didn't use this stuff, but the description is noteworthy because it points out that...

I didn't know you were an electrician. This is deeply embarrassing, and I'm afraid I'll forget. If you would please change your name from "rocket" to "electrician," it may save me future embarrassment. I simply said my hose puller didn't work on a julet connector. You recommended silicone...

I used to wonder why everyone used to say, "Don't get grease on battery posts or spark-plug terminals!" I'll bet they read it on the internet! And you have Google AI read it on the internet for you. If Google AI read it on the internet, it must be true! Your AI internet education sure beats...

If it's a single cable, I don't know why grease would affect the color. As an antiseptic, 70% is better than 90%. The water opens pores on the germ so the alcohol can get in. Amazon has 99%, which is better as a solvent. This alcohol doesn't like salt. If you put salt in the 70% solution, the...
