Words of the Weasel Part 55

Peaceably to assemble, and to petition the Government…
For a redress of grievances. First amendment. We are talking about people carrying flags and signs and posters. Marching in daylight, down routes coordinated with local authorities. Singing and chanting. Making speeches. Listening to speeches. Dispersing and going home when the demo is over. That’s peaceable assembly.
Riots are something else. Breaking shop windows, looting, setting fires, throwing stuff at cops. We citizens expect law enforcement to break them up, suppress them. Surround them; arrest a bunch of ‘em. Use fire hoses and tear gas on em. Keep them from destroying our livelihoods. Authorities that permit, or worse encourage, law enforcement to shirk their duty should be turned out of office at the next election. Or impeached immediately.

The Radial Arm Saw (RAS)
Back in the 50’s, when I was a kid, all the other kids’ fathers had shops, in the garage, in the basement, somewhere. And at least half of them had a radial arm saw in their shop. It was clear to all us kids that the RAS was the wave of the future and table saws were for old fuddy-duddies. My father had a table saw, inherited from my grandfather. The radial arm saw remained popular with do-it-yourselfers up thru the 80’s, maybe the 90’s. Then the safety freaks struck. They declared the radial arm saw to be dangerous, that using a standard blade was dangerous, that making rip cuts was even more dangerous, and the blade guard didn’t cover enough of the blade. The wood shop magazines carried the safety freak stories and stopped doing stories about using and buying radial arm saws. Today, in 2020 there are hardly any new ones for sale, and the price of used ones has sunk down to 50-100 bucks. You cannot buy a skilsaw for that little.
Me, I bought a radial arm saw back in the 70’s and I still have it. I never did get a table saw. I still have all my fingers too. Major benefit of the radial arm saw is it saves space in the shop. You can push it up against a wall and it works just fine. The table saw needs clearance all around it to handle big work pieces. The radial arm saw will make all the cuts a table saw can except for one not too important one. It will make all the cuts a chop saw can make and in addition it will rip, which the chop saw will not. You can also use your radial arm saw as a horizontal boring machine, a disc or drum sander, a shaper, a surface planer, and even as a bench grinder to keep your chisels sharp.
You do want to be careful. The tool is dangerous. The blade on a RAS or a table saw will sever any body part that comes in contact with it. I keep my hands three inches away from the blade at all times. If the work piece is too small to allow for three inches clearance, I throw it in the scrap box and find a bigger piece.
When ripping I first tilt the blade guard down on the in feed side to allow just enough room for the work to go into the blade but not any fingers that might be sliding or riding along the top of the work. Then I always set the anti kickback fingers to dig in and prevent the blade from throwing the work back at me. And I use a wooden shop made push stick for that last bit of push right next to the blade. If the piece is too narrow to safely push it thru the blade, I throw it in the scrap box and get a bigger piece. For tricky or difficult rip cuts I will clamp a feather board to the RAS table to keep the work pressed up against the fence.
In short I don’t see the RAS as more dangerous than the table saw. Both machines will take off fingers with the greatest of ease. You just have to be careful using them. Right now, a used RAS can be so cheap that you cannot go wrong buying it. Craigslist is your friend. If you are starting up a wood shop a RAS makes a fine start.

Regulating social media.
Right now anyone with an IQ above room temperature can log on to Facebook or Twitter or U-tube or the rest of them and post any damn thing he pleases. And it goes world wide. A bunch of Islamic terrorists have claimed they were recruited sheerly thru watching terrorist propaganda on Facebook and U-tube.
The owners of the platforms are the only ones who know how to delete posts, cancel log in privileges, and post comments. We have to trust them, or shut their platforms down. I think the platform owners right along have been deleting material that is clearly offensive, pornography, nudity, sex acts, snuff videos, pedophilia, BDSM, Islamic terrorist propaganda, KKK propaganda and worse. They ought to keep on doing it. Maybe step it up some.
Then we come to individual posters who post all sorts of poppycock, anti Semitic, white supremacy, Nazi, alien invasion, and other weirdo ideas. I think maybe we ought to just leave them alone. Much of it is so weird that no body pays it attention. The offensive stuff can be replied to by those who have been offended.
And then we come to posters who are elected officials. Since they got themselves elected they have support from a majority of their constituents. That’s a lot of people who think they are OK. Same goes for opposition politicos from the major parties. As a platform owner, I myself would be extremely reluctant to censor an elected official for fear of offending a lot of people and inviting retaliation. I think the Twitter people are crazy to censor the President of the US. He has brought them all sorts of viewers/readers/tweeters. If Twitter doesn’t like what Trump tweets, surely they can find some anti trump tweeters to respond to the Donald.
If we are really unhappy with the platform owners, then we can get the anti Trust lawyers to break them up. Facebook is clearly a monopoly. We would be better off with two sites competing for viewers/readers/pageviewers.

Steam Engines, beloved in song and story
The earliest steam engines, Tom Thumb is still on display at the Baltimore and Ohio museum. The design is straightforward, firebox on the bottom, a fire tube boiler mounted atop the firebox and a stack on top of the boiler. Flames rose up thru the firetubes, boiled the water, and rose up the stack creating draft to keep the wood fire burning brightly. Just four driving wheels. Tom Thumb never went fast enough to need the steadying effect of pilot wheels. This design was successful and quite a few were built. But the design does not scale well. A bigger locomotive needs a bigger taller boiler and the taller boiler won't fit under bridges.
New design, that lasted until the end of steam, laid the firetube boiler on it's side, placed the firebox at the rear, where the fireman could reach into the tender for wood, or later coal, and the stack at the front. Flames from the firebox were led forward thru the firetubes and then up the stack. Waste steam from the cylinders was vented up the stack to increase the draft and creating that distinctive choo-choo sound. This arrangement needed a pilot truck the carry the weight of cylinders, stack , and the front half of the boiler.
In my childhood all small boys knew that you could tell a passenger locomotive from a freight locomotive by looking at the number of pilot wheels. Freight ran fairly slowly, say 30 mph and a two wheel pilot truck was enough to steady them. Passenger trains reached 100 mph by 1900 and needed much more weight on the pilot truck to lead the locomotive into switches and curves. The extra weight needed four wheels to support it.
The older smaller 19th century engines located the firebox just over the rear set of drivers. This worked, but it limited the width of the firebox to 4 foot, eight and a half inches, the track gauge. Larger locomotives built after 1900 moved the firebox clean aft of the drive wheels and widened it out to 10 feet, the widest it could be without hitting station platforms. And a pair, sometime two pair of trailing wheels were added under the firebox.

Middle school was getting bad back then
I wrote this for Youngest Son back when he was doing middle school some ten years ago. I wonder if things in school are still this bad.
1. Never say the word "gun" (or shoot or fire or kill or bang-bang or...)
2. Never take any thing that looks like, sounds like, or might be accused of being, a gun to school. Same goes for any kind of knife, even a butter knife. Don't bite your food into gun shapes. Don't point a finger, or anything else at anyone. No toy soldiers, no Lego guns, no books about guns or with illustrations of guns, or people carrying guns (cowboy stories, Johnnie Tremain, Last of the Mohigans, anything like that).
3. Never say anything angry about anyone or anything. If something or someone angers you don't say anything about it. Hold it inside yourself until you get home. Never threaten anything.
4. No touching, no hitting, no hugging. Keep your distance.
5. They are always watching you and listening to you. Especially on the bus, at recess and on the Internet.
Forget any of these rules and they will throw you out of school, for good.
School was easier to survive when I was a kid.

Barrows
Barrows are traditional described as grave sites. That U-Tube lecture makes me think that the barrows served other purposes. Tribal gathering places, sacred places where shamans asked the god for good weather, good hunting and good luck. Places where seers predicted the future. We cannot know at this remove in time. I.m thinking those few graves were the graves of a few exceptional individuals, priests, kings, shamans, mighty warriors, buried in the barrow to bring good luck, bring a friendly spirit, and make a sacred place more sacred. We still do this. Look at Westminster where the British bury their kings and scientists and soldiers.

Cops and Courts should handle Campus Sexual Harrassment
Rape is a serious crime. Used to be a death penalty offense. We have backed off on the death penalty, but it is still a serious crime. I don't like students getting judged by a bunch of college admins for serious offenses like rape. That's what we have police and courts for. And American courts are pretty good on due process, far more so than lefty college admins. When someone complains to the college of campus rape or sexual harassment, the college should offer her (or him) a ride to the police station, and a ride back.
