the "not worthy of it's own thread" thread

Distance can be measured in Miles,
Speed in MPH

Distance can also be Nautical Miles
So why is Speed KTs and not NPH?

What’s with the K? Knots as in knots in the rope shoved over the ship to measure speed? So make it Knot Miles, not Nautical Miles.

This question is the unfortunate side effect of laying in bed all day with a bad cold / flu / bubonic plague.

Carry on……

Probably cause nautical miles sounds cool, whereas "knot miles" sounds like it'd be invented by someone impaired by the bubonic plague.

(I kid, I kid... Get well soon!)
 
I suspect the term "knots" for nautical miles per hour predated "miles per hour" by quite a bit, though I could be wrong.
 
It could have been created by a guy named Don……

Yes, knots in a rope shoved off the ship. They counted how many knots passed through the hand during the time sand passed through the glass timer. The rope was less than a mile long, so "knot miles" doesn't make sense either.

I finally noticed it was Spring already... took in the driveway markers.

Watch out for snow. You've been warned

sorry for replying to my own post...

as I said, took in the markers aaaaaaand the temps dropped below freezing for the first time in several weeks Saturday.... aaaaaaand we had a few snow sprinkles this morning.

so much for "spring" grumble grumble grumble

Why is it that there's an inverse relationship between the speed at which you want something and the speed at which it moves? I ordered a couple parts from Spruce in Chicago on Sunday. I didn't need them super fast, I was hoping for Wednesday. Knowing that standard mail often takes a whole week, I spent a little extra for "priority mail", which was cheaper than UPS/Fedex, and was supposed to get it here in 3 days. I'm sure you can see where this is going...

So I'm never using USPS again. They just get worse and worse.

So I bought a thing on eBay. It may or may not have been a toy train. Anyway, this one might actually be more ridiculous:

I mean...it drove right by...
And no, I didn't have a choice of carrier.
Another week you think?

Altoona, PA does have a pretty cool train museum, so perhaps they had to certify it first?!

The travel time between Indy and KC looks like they put the box on the toy train rather than putting the toy train in a box. Choo choo, mothertruckers!

Meanwhile, I was able to find some actual footage from our local post office…

 
Took me a while to realize that Charlie is so illiterate he was reading Philadelphia as 'Pepe Silvia.'


Just made a new set of wires and javelins for my biplane, rigged and tensioned everything and for the first time ever it flies hands-off and doesn't slowly roll into an uncommanded bank. :eek:

Nice. Did you do all of the crimping yourself? Probably a silly question - I wouldn't be surprised if you twisted your own cable from individual wires. :)
 
Yup. I bought a used Nicopress crimper and go/no-go gauge on eBay a while back. Got the sleeves and wire rope from McMaster Carr. I love Experimentals. :biggrin:

The original builder hadn't secured the loose ends with heat shrink tubing, it was chapping my ass.
 
So I changed the oil and set the empty bottles aside. A day or three later, each is showing about 2/3 of an ounce.

How long do I need to leave the oil bottle inverted before it's truly empty?

I leave mine for a long time. Amazed at how much you can salvage.
 
There is a guy at our home base who collects the bottles and sets them up into a common drain he built. He says he gets about a quart a week of "residual oil." He has 3-4 cascades, one for each of the common brands and weights.

What's funny is he is quite well off, has his own hangar and flies a twin, but salvages oil...We truly are a strange breed...

I leave it exactly as long as it takes to open the next bottle. Life is short.

I use gallon jugs. I wonder if the internal wetted surface is any less?

slightly different problem... I have a package that is kind of stuck in wilington ct. (it was originally scheduled to be delivered 30 March...)

For cars with electronic temperature control, are there any with a deadzone? Or are they all like Ford with one temperature setting (e.g., 72) with the AC going on if up above 72 and the heat going on if below 72 (which is stupid stupid stupid)?

Do you mean hysteresis?

you know what they say: penny foolish pound foolish

no. I don't think hyteresis applies. When you program a thermostat at home, do you leave it with a temperature range or do you want the heating/cooling to keep the temp EXACTLY at one value? I usually see the recommendation to turn on the AC if the temp gets above, say, 78, and turn on the heat if the temp gets below, 68. That 68-78 range would be a deadzone - no heat, no AC. At least that's my understanding of the term deadzone

maybe the correct term is "dead band"

In my household, it's "dead husband." I put the car climate control on Auto, 72F, and sync all zones. This usually leads to a comfortable ride with minimal noise, minimal dog fur blowing around, and zero attention diverted to adjusting the climate control. My wife usually gets upset about a mile before the destination (whether the total drive was 2 miles or 250) that there is no airflow, she can't stand the stale air, etc., and then starts adjusting the fan speed and temperature of various zones while rolling down the window. I don't even want to know what she does with the house thermostats while I'm at work.
 
Mozilla released a new version of Firefox... 1 April.

I think I'll pass on that update... for no particular reason...

Back when I was a teenager we just called it 260 air conditioning..... 2 windows open, 60 mph...

What typically works best is to open just two windows just a few inches - both on one side or diagonally opposite. The back window is the inlet and the front is the outlet. With windows open on one side you get a vortex. Diagonally opposite you get a cross flow.

Opening all the windows just gives you noise and drag.

Even better if you have a truck with moonroof and power sliding rear glass. Vent the moonroof, then open the back glass to circulate air in the cabin which makes a cool breeze on your neck. The more you open the back glass, the more flow you get. No buffeting, very little wind noise. I used to use it almost daily in my '08 F-150. Probably doesn't work well if you have a tonneau cover on the bed.
 
I've noticed that any newer vehicles I've driven have horrible buffeting if you roll down the rear windows. Some if you roll down both, but my pickup will get pretty bad with just one.

a couple of mine have a large not-so-sweet spot that will have signficant buffeting. Close the window some or open it more and the buffeting goes away. Yet another reason why I want a fresh air vent without heating/cooling... just give me the fresh air (which, by the way, should go through the cabin filter).
 
Best deal in a pickup truck was rolling down the windows, flipping the triangle vents around the other way, and leaving the sliding back window open a bit. And being happy you had that fancy sliding back window.

I much prefer air conditioning.
