  • Interesting Show on TV, don't know if its new

    But its called "How Things are Made". I watched 2 episodes last nite. I saw how molds are made for plastic injection, bikes, eye protection glasses, oil filters.. etc.

    Not an in depth look by any means, but interesting.

    I have seen some of them , the one where they make nuts and bolts was realy good.

      Yeah, that's a good show. They even showed how sausage is made one time.

        I'm dating myself here, but there used to be a show I think on PBS called "Connections" (I think) and they would take something in history and connect it to today, like one I remember was Gunpowder produced cannons which changed castles which led to surveying equipment (for lining up and firing the cannons) which led to mapmaking of countries which led to a central beacon in England as a center point which used limelight but by the time it was constructed the had discovered arc light .................eventually up to television. Kind of neat. They even had a show that traced the origins of computers from rug making.

              That is also a good show (Connections, by James Burke) but sometime the "connections" are a bit of a stretch. Even though it may seem logical that a particular device/method etc. was a logical forerunner of something else there isn't really much of a connection.

              In the case of computers the real connection was the invention of programmable looms. The main thing about the programmable loom was that the programming could be changed at will. It wasn't a computer since it didn't have the capability to change it's own programming but it was the first use of a manufacturing device that could have it's operations changed by following coded instructions.

              Making carpets wasn't the real impetus for this development, complex fabric patterns were.

                How It's Made is a great show indeed. I find myself wanting longer segments that explain things in more detail. Especially when they show things being made out of metal!

                The one on bicycles was very interesting. It showed the steel frame tubing being cut to length with a parting tool, stock held with a collet and then "fish-mouthed" before being bent on a CNC bender. The tubes were placed into a jig and brazed together. They just dropped a measured chunk of the brazing material down the tube and then some torches fired up to heat the whole joint up 'til it was bright red. The braze joint flowed out beautifully and they let it air cool. After the frame was completely brazed together, they put it into another jig and tweaked out by hand any warpage caused by the heating/brazing process.

                They showed the whole wheel spoking process, tire/tube mounting, powder coating the frame, controls assembly, etc, etc. Amazing how much hand work goes into a bicycle!

                  The original Connections was much better than the sequal. The punch cards on the loom (which controlled pins, which selected threads) was used on a device for immigration so that all kind of records could be kept. I was in India last year, and of course had to buy some carpets and got to see hand made stuff but the interesting shops were still using looms with cards. Some of the cards or patterns had to be over a hundred years old. Not sure how old the cards were, but many of them were made of wood and definitely had some age on them.

                    Called a Jaquard Loom, after the man who invented it.

                      Connections and programed loom

                      I wonder if they ever put the original connections on a tape or DVD. They were great and worth seeing again. A programed loom was and probably still is in the Henery Ford Museum in Dearborn , Michigan. The machine shops, museum, and a lot of great stuff is there. A day to see the village and another to see the mesuem is needed it is so large.

                        On one episode of How It is Made they showed metal spinning. They showed a CNC spinning lathe and that was neat but the best part was when they showed an old spinning hand who must have been making lamp reflectors for a couple of hundred years. He would take a big disc of aluminum and slap it on the lathe and in about 30 seconds, presto! another reflector. I know if I tried to copy what he did there would be another UFO zinging across the shop like Odd Job's hat. I suspect even a good CNC couldn't turn out more work than he did.

                          I saw that episode as well. Those are the really low end bikes that sell at "Canadian Tire" etc. The thin walled tubing used in quality bikes would not withstand the abuse that brazing method puts the tubes through.

                          I've been building custom frames a a hobby for 8 years and just started a blog on the subject.

                            The loom is still in the Ford Museum, a must see site for any gear head. Has anyone seen a "show" on How in the heck did somebody make the "FIRST" thread??? Handmade? I know you can make almost any part on a lathe but how did they make the parts for the "First" lathe. Bet hand filing that lead screw was interesting. Oh by the way, I was boring out a compressor housing in Florida awhile back and asked what the tolerance was on the about 60" diameter and the guy told me within .001". This was with a portable machine by the way. I asked him if he knew what a .oo1" was. He walked off and came back with a drill bit grinder he had made. The largest drill it would handle was .007". They used needle stock for the drill bits. The feed on the handle was .001" for every 10 revolutions. The "feed nut" was leather so that the "accuracy" of the feed screw was averaged over the length of the nut. I was humbled. The drills were for drilling plates for a carpet thread extruder. BTW did you know that carpet thread is not round but is Y shaped. It makes it feel softer? And I get paid to learn this stuff.

                              Thats an awesome show, I think it started on Discovery Science and they moved it to the Discovery channel. They had how screwdrivers were made yesterday. I never knew that contact lenses are made with a small lathe, from little chunks of.... hell, I cant remember. About time they had good shows like that instead of all the reality show/spoiled ass whiney actors show.
