The last day of our Simple Machines unit was probably our favorite. We spent hours and hours making and toying with different ways of making pulleys and wheel-n-axles! We started (as always) by reading a couple of books. We did an activity to show investigate which way of looping the rope made it easier/harder to pull the broom-handles together: The kids really enjoyed Pull, Lift, and Lower: A Book About...

This medium cage derailleur can accommodate a large range of gears, being suitable for cassette sprockets ranging from 11 - 34T. The wide link design provides precise gear shifting and increases its rigidity. The 11-tooth pulleys reduce chain noise for a quiet ride and ensure the pulleys last, with alloy bushings that contribute to the smooth running of the derailleur.

An Elevator for My 10'x12' Storage Shed: When the town we live in told me I couldn't replace an old shed with a new, larger one because they had increased our property's setbacks to 20' along the sides and 50' from the water, I was forced to place a much smaller one, closer to our house (I…

Make turning the lights on fun with this gear-shaped, steel light switch cover! Just flip the metal lever to turn lights on and off! The design fits most toggle wall switches in the USA by fitting over the existing wall switch. It is extremely easy to install. Simply unscrew your existing switch plate cover, and screw this one in in its place. Because it is made from 1/4 inch raw steel, it provides an authentic Industrial look. My lever system has a bolt and nut design that allows you to adjust the amount of torque needed to flip the lights on and off. Your purchase comes with a small, matching wrench to help you adjust the bolts. It also comes with a steel spacer plate that ensures a tight seal against the wall and also prevents wobbling and unsightly gaps. Base plate measures 4 ¾ inches tall by 2 ¾ inches wide. Levers extend 4 ¾ inches from the wall. When installing, a good option is to turn your existing toggle switch upside down so that the up/down, on/off action of the levers is not reversed. This design is only compatible with toggle switches (the kind you flick up and down with your finger). If you have a dimmer or rocker switch, I can include a 15A-120V toggle switch with your order at no extra charge. Please notify me via a conversation if you need a complimentary toggle switch. If you are looking for light switch covers that are compatible with dimmer knobs, these links will take you to my dimmer switches: Single Dimmer - https://www.etsy.com/listing/255435232/urban-industrial-lighting-dimmer-light?ref=shop_home_active_11 Double Dimmer - https://www.etsy.com/listing/384588146/dimmer-light-switch-cover-gear-lever?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=steampunk%20dimmer%20sillcock&ref=sr_gallery_2 Triple Dimmer - https://www.etsy.com/listing/246749499/industrial-triple-gang-light-switch?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=steampunk%20dimmer%20sillcock&ref=sr_gallery_1 Built to last and made in the USA from CNC plasma-cut 1/4 inch steel plates.

The Problem Our studio is already full of easels. We have somewhere between 12 and 15 of them depending on whether we’re counting the slightly broken ones that we use only in a pinch. That sounds like a lot but it isn’t because there’s not one of them that I get to call “mine”. My wife …

Permite convertir un movimiento giratorio en uno lineal continuo, o viceversa. Este mecanismo se emplea para la tracción o elevación de cargas por medio de una cuerda. Ejemplos de uso podrían ser: Obtención de un movimiento lineal a partir de uno giratorio en: Grúas (accionado por un motor eléctrico en vez de una manivela). Barcos (para recoger las redes de pesca, izar o arriar velas, levar anclas...), Pozos de agua (elevar el cubo desde el fondo). Elevalunas de los automóviles. Básicamente consiste en un cilindro horizontal (tambor) sobre el que se enrolla (o desenrolla) una cuerda o cable cuando le comunicamos un movimiento giratorio a su eje. Para la construcción de este mecanismo necesitamos, al menos: dos soportes, un eje, un cilindro (tambor) y una manivela (el eje y el cilindro han de estar unidos, de forma que ambos se muevan solidarios). A todo esto hemos de añadir una cuerda, que se enrolla alrededor del cilindro manteniendo un extremo libre. Los soportes permiten mantener el eje del torno en una posición fija sobre una base; mientras que la manivela es la encargada de imprimirle al eje el movimiento giratorio (en sistemas más complejos se puede sustituir la manivela por un motor eléctrico con un sistema multiplicador de velocidad). Este sistema suele complementarse con un trinquete para evitar que la manivela gire en sentido contrario llevada por la fuerza que hace la carga. Ejemplo de un proyecto que incorpora un trinquete: Caballete de cabria. En la realidad se suele sustituir la manivela por un sistema motor-reductor (motor eléctrico dotado de un reductor de velocidad). Fuente: Esta información ha sido obtenida de MECANESO. ¿Cómo fabricar un torno? Una vez analizada la información anterior hemos fabricado el mecanismo utilizando los siguientes materiales: Listón de samba 18*9 mm. Varilla roscada M4, Tuercas y arandelas M4. Palito de barbacoa. Contrachapado de 5 mm. Mecanismo torno 1.- Cortar dos soportes de listón de samban 18*9 mm. 2.- Cortar dos casquillos metálicos. CASQUILLO METÁLICO Soporte de madera 3.- Trazar en contrachapado de 5mm el brazo de la manivela. 4.- Cortar el brazo de la manivela, usando una sierra de marquetería. 5.- Realizar dos agujeros: uno de 4 mm y otro de 3 mm. Brazo de la manivela 6.- Cortar dos triángulos, del listón de madera de samba. Los triángulos permiten pegar los soportes verticalmente en la basa, aportan estabilidad sistema. Soporte con triángulos 7.- Enrollar una tira de cartón en un trozo de varilla roscada de unos 8 cm aproximadamente. Cartón enrollado 8.- Cortar dos círculos de cartón. 9.-Montar los círculos uno en cada extremo del cartón enrollado a la varilla roscada. 10.- Fijar los círculos con tuercas y arandelas. Sistema tuerca-contratuerca. Tambor del torno 11.- Pegar los soporte a la base. Mecanismo torno Ejemplo de la maqueta de un ascensor, la cual incorpora el mecanismo torno.

I have been thinking of making some nice wooden blocks for Arwen over the summer along with a new pair of 9’ 6” oars. Now the garage has been cleared of scooter debris there is no excuse. This is elegant craftsmanship and I am sorry I don't know who to attribute the copyright to I do rather fancy having smaller versions of these on Arwen I’ve been researching about block making on the internet. Joel on his navigator blog has a lovely blog entry detailing how he makes them. His have lovely brass straps. And I have to admit, I like the way he has gone about it. Although we have never met, I have a huge amount of respect and regard for Joel. He is a thoughtful craftsman and sailor and these qualities permeate through his blog, his workmanship on ‘Ellie’ his navigator and in his comments to people queries. A courteous, good humoured gentleman craftsman is Joel. He’s probably chuckling reading this and thinking ‘if only he knew me better!’ Go here to find Joel's blocks and guide on how to make them: http://navigatorjoel.blogspot.co.uk/2011/03/download-my-how-to-guide-to-make-lovely_04.html On the other hand, getting back to blocks, I am attracted to the type of block that comes with a rope strop. Be under no illusion, I know these will take far more work and craftsmanship than I possess but this is how we grow isn’t it. As humans, we frequently bite off more than we can chew; we make mistakes and then if we have any sense we learn rapidly from them! I’ve never played with bitumen twine before but it does sound rather fun doesn’t it! being of a somewhat dim persuasion, I've lost my copyright credits list and so can't remember where I got these from. I think it was either Nick on the Woodenboat forum or from Duckworks If they are yours please drop me a comment so I can thank you and attribute them to you...or of course remove them if need be. So, I’m thinking ash blocks, brass pins, tufnol sheaves with rope strops which have been properly bound. 3” in size, I’d need around 3 or 4. I’d need to replace the two side deck blocks with wooden ones that had Joel’s brass straps because they will have to stand on end within springs to sit proud of the deck. The mainsheet block on the end of the boom will need some thinking through. I have two blocks under the deck mounted to the front thwart around the mast where various halyards come down from the mast and through the deck and then run aft to the rear of the centre case. I think they call this binding 'racking'? Of course there are then the blocks on the centreboard up haul – a triple and a double. Um – so that would be about 10 – 12 blocks. Now I have a band saw and a router so that should help. There are various rasping files. I have some measurements of sorts. There is quite a bit of advice on the duckwork's site and on the woodenboat forum……..so now it’s a matter of thinking it through more carefully over some cuppas; pricing it out; going to ‘she wot must be obeyed at all times’ (or ‘her in-doors’ as she is affectionately known by me and number one son) to get the cash…….and then running away fast as she explains in no uncertain terms that if I want to retire at 58 from teaching and have a skiing holiday at Christmas, Arwen can’t have new shiny blocks! If I really planned it out carefully (that would be a first I hear my son, daughter, wife and father all mutter at the same time) I could set up an assembly line production I’ll keep you all posted! Watch this space…a significant war of attrition is about to take place in Arwen’s household…..I wonder who will blink first! Oooh! another thought, the smell of boiled linseed oil wafting up from the garage through the floorboards of the sitting room.......oooooh! that does sound nice (well to me anyway!) I really am genuinely sorry to have misplaced my copyright acknowledgement notes Please will people be patient and forgive this temporary lapse Steve

This chart was used by Dr. Marshall Nirenberg, a scientist who won the 1968 Nobel Prize in Physiology or Medicine for his work in helping to “crack the genetic code,” or to understand the way DNA codes for the amino acids that are linked to build proteins. By 1966, Nirenberg announced that he had deciphered the 64 RNA codons for all 20 amino acids. This chart lists the correspondence between these codons and amino acids..
