Introduction: Grinder2grater (de Amoladora a Rallador)

Picture of Grinder2grater (de Amoladora a Rallador)


Ya he comentado que soy un guardador compulsivo. Es difícil que yo tire a la basura algo que potencialmente pueda servir, aunque sea como pisapapeles. Por tal motivo, cuando hace tres años un "amigo" me devolvió quemada mi querida amoladora de mano, decidí archivarla en el garage a espera de alguna oportunidad. Hace poco me decidí a darle un destino útil, y acá vamos.


I commented that I am a compulsive keeper. It is difficult for me to throw away something that could potentially serve, even as a paperweight. Therefore, when three years ago a "friend" gave me back burned my dear hand grinder, I decided to file it in the garage waiting for a chance. I recently decided to give it a useful destination, and here we go.





Step 1: La Necesidad Es Madre Del Ingenio (necessity Is Mother of Invention)

Picture of La Necesidad Es Madre Del Ingenio (necessity Is Mother of Invention)


Lo primero que se necesita es una esposa que cada vez que se dispone a hervir fideos, pregunte "¿hay queso rallado?". En casa no compramos esos quesos que vienen en sobrecitos, porque son caros y suelen tener gusto a cáscara o a humedad. Preferimos comprar un trozo de queso de rallar no muy caro, dejarlo en la heladera hasta que sazone, e ir rallándolo a medida que se necesita. Yo tengo un rallador a manija que heredé de mi madre, es bueno pero solo sirve para rallar queso. Intenté dos o tres veces rallar zanahoria, pero es más el trabajo de limpiarlo que el que se ahorra uno con él. Consecuentemente, me dije "necesito un rallador multifunción, y lo voy a hacer yo mismo".

Destripé totalmente la vieja amoladora, y luego de analizar la factibilidad del proyecto, corté el eje del rotor en la parte donde comienza el bobinado. Me quedé con la parte de adelante o cabezal, y lo demás... no, no lo tiré, lo guardé para otra vez. (!)


The first thing you need is a wife that every time she goes to boil noodles, ask "Is there grated cheese?". At home we don't buy those cheeses that come in packets, because they are expensive and tend to taste shell or moisture. We prefer to buy a piece of cheese for grate, not too expensive, leave it in the refrigerator to season, and grate it as needed. I have a handle grater that I inherited from my mother, it is good but only serves to grate cheese. I tried two or three times to grate carrot, but is more work to clean it than you saves using it. Consequently, I said "I need a multifunction grater, and I'll do it myself".

Completely gutted the old grinder, and after analyzing the feasibility of the project, cut the rotor shaft in the part where the winding starts. I kept the front or head, and the rest ... no, I don't threw it, I kept it for another time (!)

Step 2: �Hacela Configurable! (do It Customizable!)

Picture of �Hacela Configurable! (do It Customizable!)


Cuando ya estaba por hacer el soporte principal del rallador, le expliqué a mi hijo que me proponía hacer un rallador horizontal, y él dijo "yo pensé que el disco de rallar iba vertical". Eso me dio una idea interesante: ¿por qué no hacerlo inclinable? Así que buscando entre mis cosas hallé un viejo amortiguador de auto cuyo diámetro resultó ideal. Corté con cuidado un aro del mismo, dejando cuatro pestañas que doblé hacia afuera y agujereé, para poder atornillar la pieza al cabezal de la amoladora, que a partir de ahora denominaré "cuerpo principal".


When I was about to do the main support in the grater, I explained to my son that I intended to make a horizontal grater, and he said "I thought the grating disk was vertical." That gave me an interesting idea: why not to do it tiltable? So looking through my old things I found a car shock absorber whose diameter is ideal. Carefully cut a ring of if, leaving four tabs that fold out and bored, to screw this piece to the head of the grinder, which will now call "main body".

Step 3: La Base (the Base)

Picture of La Base (the Base)


Con varilla de hierro de 1/2" por 1/8" hice un soporte que aloja el cuerpo principal, permitiendo girarlo hacia amos lados dentro de ciertos límites, para poder usarlo con mano izquierda (yo soy zurdo) o derecha. Dicha base se ajusta a la mesa de la forma tradicional, mediante un tornillo mariposa terminado en una arandela cónica.


With iron rod 1/2" by 1/8" I made a stand that holds the main body, allowing owners turning to side within certain limits, to use with left or right hand (I'm left-handed). This base adjusts to the table in the traditional way, using a thumb screw terminating in a conical washer.

Step 4: El Disco Rallador (the Grater Disk)

Picture of El Disco Rallador (the Grater Disk)

Mi primer intento, fallido para poder aprender algo, lo hice con un platillo que parecía acero inoxidable pero resultó ser hierro común con una delgada capa de cromo. Al ser demasiado delgado, no tenía resistencia mecánica suficiente para poder rallar queso duro ni zanahoria, se pandeaba.

Mi segundo intento fue exitoso, porque usé chapa gruesa. Los agujeros, de 3.5 mm, están distribuidos de manera que al girar el disco cubran toda la superficie del queso a rallar.

El disco va fijo mediante dos pequeños tornillos a la tuerca redonda que normalmente aprieta el disco de la amoladora. Dado que el soporte redondo donde este apoya ya no se necesita, agregué un pequeño trozo de tubo de hierro para que el disco rallador quede nivelado con el extremo del tornillo del eje. Esto tiene la ventaja de que bajo el disco rallador se forma una cavidad un poco más alta, y por lo tanto con mayor capacidad.

Tanto a mi mujer como a mí nos gusta el queso rallado grueso, pero de ser necesario puedo hacer otro disco con agujeros más chicos, o con superficie raspadora para hacerlo molido.


My first attempt failed, to learn something. I did it with a dish that looked like stainless steel but was found to be common iron with a thin layer of chromium. Being too thin, it had not strength enough to grate hard cheese or carrots, because it twisted.

My second attempt was successful, because I used heavier iron plate. Holes, 3.5 mm, are arranged so that turning the disc they cover the entire surface of the cheese to grate.

The disc is fixed by two small screws to the round nut that normally press the grinder disc. Since the round steel washer where the disk seats is no longer needed, I added a small piece of iron pipe in order to the grating disk is flush with the end of the screw shaft. This has the advantage that under the grater disc leaves a cavity a little higher, and therefore more capacity.

Both my wife and I we like coarse grated cheese, but if necessary I can make another disk with smaller holes, or rasp to make it ground.

Step 5: El "apoyaqueso" (the Cheesesupport)

Picture of El "apoyaqueso" (the Cheesesupport)


Hice una pieza con forma que recuerda a una espuela, que abraza el cuerpo principal, se fija con dos tornillos en los agujeros roscados que el cabezal de la amoladora traía para alojar el mango, y queda en posición mediante una uña que calza en una de las ranuras del cuerpo. En el extremo donde iría la rueda con púas en una espuela, mi pieza tiene un trozo de chapa gruesa de hierro que pivota alrededor de un remache, y que cuando está horizontal sirve para apoyar el queso mientras se ralla.


I made a piece in a shape that resembles a spur, which embraces the main body and is fixed with two screws into the threaded holes that the grinder head brought to accommodate the handle, and is in position by a nail that fits into one of the body's grooves. In the end where a spiked wheel would be on a spur, my piece has a offcut of thick iron plate that pivots about a rivet, and when horizontal is used to support the cheese while is grated.

Step 6: El "apoyadiscorrallador" (the Graterdiscsupport)

Picture of El "apoyadiscorrallador" (the Graterdiscsupport)

Aunque el nuevo disco es un poco más resistente que el primero (ver paso 4), por las dudas le hice un soporte que lo sostiene por el borde mientras gira. Es de chapa acerada, que me regalaron en un lugar donde venden hierros. Tiene cuatro radios sujetos al perímetro con remaches de aluminio, y al cuerpo principal mediante una abrazadera convencional. Por el momento los cuatro radios parecen ser suficientes, pero de ser necesario podría agregarle hasta cuatro más.

Como todos mis proyectos, la estética va detrás de la funcionalidad. Por eso los radios van remachados en la parte exterior del perímetro, de manera que no obstaculicen la limpieza de la cavidad donde queda el queso rallado. Si estuvieran remachados por adentro serían incómodos pero invisibles, y por lo tanto el aspecto del aparato sería un poco más aceptable.

El perímetro no es cerrado, tiene una abertura por donde sale el queso rallado. Esa abertura se acomoda apuntando hacia abajo.

Sobre los cuatro rayos va simplemente apoyado un disco de plástico, proveniente de la tapa de un viejo recipiente hermético. Se retira para lavarlo luego de usar el aparato.


Although the new disc is a little tougher than the first (see step 4), just in case I made a bracket that holds its edge as it rotates. It is of steely sheet, which gave me in a blacksmith's shop. It has four radios subject to the perimeter with aluminum rivets, and to the main body by a conventional bracket. At the moment the four radios seem to be sufficient, but if necessary I could add four more.

Like all my projects, aesthetics goes behind the functionality. So the radius are riveted on the outside of the perimeter, so as not to hinder the cleaning of the cavity where the cheese is grated. If they were riveted on the inside would be uncomfortable but invisible, and therefore the shape of the product would be a bit more acceptable.

The perimeter is not closed, has an opening where the grated cheese gets out. That opening fits pointing down.

Over the four radius, simply supported is a plastic disc, from an old airtight container lid. It is removed to wash after using the device.

Step 7: La Manija (the Handle)

Picture of La Manija (the Handle)


La primera versión de la manija era de longitud fija, pero cuando caí en cuenta de que la velocidad del disco rallador era un poco lenta, decidí hacerla de longitud variable. Eso permite hacerla muy cortita para girarla a mayor velocidad con el mismo esfuerzo, pero si el queso fuera muy duro, alargando la manija se obtiene más palanca. Diseño digno de la ISS, realmente. NASA, acá estoy!


The first version of the handle was fixed length, but when I realized that the grater disk speed was a bit slow, I decided to make it variable length. That allow to set it very short  to rotate faster with the same effort, but if the cheese were very hard, lengthening the handle you get more leverage. Design worthy of the ISS, really. NASA, here I am!

Step 8: Prueba (test)

Picture of Prueba (test)

Las pruebas con el disco rallador primera versión no quedaron documentadas, pero como dije antes, no fueron satisfactorias. Con este disco no tuve prácticamente ningún problema. Lo único observable fue que al estar sin sazonar del todo el queso, es un poco blando, y las ralladuras se adhieren un poco al disco y se acumulan en la cavidad debajo del mismo. Pero confío en que eso no sucederá con un queso bien seco. Con zanahoria va a pasar lo mismo que con el queso blando, pero eso no tiene solución, hay que asumirlo como es.


Tests with grating disk first version were not documented, but as I said before, were not satisfactory. With this disk I had virtually no problems. The only thing noted was that by being not completely seasoned, the cheese is slightly soft, and the scales stick a little to disc and accumulate in the cavity beneath it. But I hope that will not happen with a dry cheese. With carrots will happen as with soft cheese, but that has no solution, we must assume it as is.

Step 9:

Picture of

Esta fue una nueva versión, un poco mejorada, que hice para mi hijo. El único problema es el tamaño, tuvo que agrandar la casa para poder tener el rallador.

--------------------------------------------------------

This was a new, slightly improved version, which I did for my son. The only problem is the size, he had to enlarge the house to be able to have the grater.

Porque mi Espanol es malo, voy a traducir de Ingles, tambien. No quiero a "robar su trueno", pero tengo un idea (o dos) para ti. Por el disco de metal: un tapa de olla de un cacerola usada, posible? Aqui en USA, tenemos una tienda llamada "Harbor Freight" donde puede encontrar herramientas muy baratos.. por ejemplo, la amoladora, when it's on sale, cuesta approximado US$10, pero es basura hecho en Chine, por seguro!. Otro idea es usar un taladro para el motor. Y el ultimo idea es un regulador/variador de velocidad para controlar la velocidad del motor electrico. Bien hecho, y gracias por sus gran instructables!

Because my Spanish is bad, I will translate from English, too. I do not want to "steal your thunder" but I have an idea (or two) for you. For the metal disk, a used cooking pot lid, maybe? Here in the U.S., we have a store called Harbor Freight where you can buy very cheap tools .. For example, the grinder, when it's on sale, costs approximately $ 10, but is junk - made ​​in China, of course!. Another idea is to use a drill motor. And the last idea is a speed regulator to vary the speed of the electric motor. Well done and thanks for your great instructables

Thanks, solaralternatives.

This grater has no motor, it is "by muscle".

I am a moderate ecologist as you, too. I have done some solar cookers, but I never get the minimum response from others.

Hi Osvaldo
I have seen here (Spain) Moulinex electric grater, which it does is turn a cone (several types), the grating, the product is within the cone, which is habierto the distal end, dropping the scratches,
It would be like you've mounted the disk, but instead of grating by the circular, the song does, only that is longer and that is where you have holes, slots, ...
you can see in the picture attached
I hope you help
congratulations on your work, you are an inspiration

rimar2000 (author)limonchi2011-10-15

Hello Limonchi, thanks for your kind words.

I have an old grater with handle, which has a cylinder where the Moulinex has the cone. It's great for grating cheese, but for carrots is a mess, and besides the very tiny grating.

The disc is a little better than the cylinder, it was discovered when they began to use the primitive gramophones. I can make quickly new disks with different characteristics. Even the after cleaning is easier and faster with a disc than a cylinder or cone.

limonchi (author)2011-10-15

Hola Osvaldo
he visto por aqui (españa) un rallador electrico moulinex, que lo que hace es girar un cono (tiene varios tipos), al rallar, el producto queda dentro del cono, que esta habierto por el extremo distal, dejando caer las ralladuras,
Sería como el disco que has montado, pero en lugar de rallar por la parte circular, lo hace por el canto, solo que es mas largo y es alli donde tiene los agujeros, ranuras,...
lo puedes ver en la imagen adjunta
espero que te ayude
enhorabuena por tu trabajo, eres una inspiracion

rimar2000 (author)limonchi2011-10-15

Hola limonchi, gracias por tus elogiosas palabras.

Yo tengo un viejo rallador a manija, que tiene un cilindro en el lugar donde el Moulinex tiene el cono. Es muy bueno para rallar queso, pero con la zanahoria se hace un enchastre, y además la ralla muy finita.

El disco es un poco mejor que el cilindro, eso se descubrió cuando se empezaron a usar los primitivos gramófonos. Yo puedo hacer rápidamente nuevos discos con diferentes características. Incluso para la limpieza posterior, es más rápida y sencilla con un disco que con un cilindro o cono.

retrotimelord (author)2011-10-13

i would like to see this done with a angle grinder

rimar2000 (author)retrotimelord2011-10-14

It is done with an angle grinder!

Or maybe is better to say "it is done with an angle grinder's corpse"

Please read my response at mikeasaurus's comment.

raiderdk (author)2011-10-08

Rimar te admiro :D. Todos tus instructables son geniales, imaginativos y muy utiles.

¿Puedo sugerirte algo?
He pensado en como evitar que se quede el queso/zanahoria en el espacio entre discos.
Quizás si eliminas la cuarta parte del disco de plastico ( la mas cercana a la abertura lateral ) preparando una tobera/rampa puedes hacer que caiga por ahí y se deslice hasta el plato, o incluso adaptarlo para enroscar un frasco y que quede automaticamente envasado.

Otra opcion es poner una sola aspa que gire solidaria al disco rayador y cubra el espacio entre los dos discos y asi mueva y empuje lo que ya has rayado.

Incluso las dos opciones al tiempo, pueden dar buen resultado.

Seguiré tus instructables son intenrés.

un saludo.

I'll try to translate for everyone else :).

To avoid keep cheese or carrot between discs, cutting a quarter part of plastic disco the one near to lateral hollow maybe can solve the problem, also a slide ramp to a dish or even a jar can be builded to extract it quickly .

Another option is make a spining blade to push cheese/carrot to the hollow.

Both of them also are compatible.



rimar2000 (author)raiderdk2011-10-08

Gracias por tu elogio, no creo merecerlo.
Tus sugerencias son interesantes, veré si puedo hacerme un tiempito la semana entrante para probarlas. Voy a estar muy ocupado porque vienen albañiles a rehacer un galponcito que tengo en el fondo, cosa de poder instalar mi modesto taller ahí.

Thank you for your compliment, I think don't deserve it.
Your suggestions are interesting, I'll see if I can do a little time next week for testing. I'll be very busy because builders come to redo a small shed I have in the background, so I can install my humble workshop there.

mikeasaurus (author)2011-10-07

I like this.
I've been working on my own homemade cheese grater, too. I may have to borrow a few of your great ideas here.

rimar2000 (author)mikeasaurus2011-10-08

I DID THAT SOME YEARS AGO!

That day I discovered the ICCTPAT (impalpable cheese cloud that permeates all things).

A few minutes after, I dismantled the device. Days ago I found its rests into my stuff, and put them to fire. That story would have been interesting to "my Featured Author"

wilgubeast (author)2011-10-07

What a great repurposing of a broken tool.

I was secretly hoping that you had just modified the grinding wheel to grate cheese very, very quickly. But this is probably safer. :-D

Thanks, I8nite!

¿Too many English errors?

l8nite (author)rimar20002011-10-07

It's readable and understandable, there are always errors in syntax (word placement in a sentence) when using a translation program and sometimes the incorrect word is used but it can all be figured out

rimar2000 (author)l8nite2011-10-08

Well, then it it enough for me. Thanks for reading!

Please embrace your talent! It stands out! Really! Have a super weekend!

ChrysN (author)2011-10-07

Brilliant! I find using a handle grater to be really tedious, this is a great solution.

rimar2000 (author)ChrysN2011-10-07

Thanks, CrysN.

A few hours ago I grated carrot, and as I expected, it was almost all within the cavity under the disc. But I had no problem in passing it from there into the salad bowl. Also, remove the disk and rinse everything is very simple. Very easier than the purchased grater.

Phil B (author)2011-10-07

Very well done, Osvaldo. If you showed me the cheese you grated I would never have guessed it was done on a grater someone made. Very clever. It is sad that your friend ruined your grinder, and apparently did not pay you for it or bring you a new one. I once knew a man who carried a small magnet in his pocket. He worked in the railroad switching yard at a steel mill. When he saw a piece of steel on the ground, he touched it with his magnet. If the magnet did not stick, he knew it was stainless steel. He liked to get stainless steel. With it he cut and filed crosses about 85mm high. They could be polished to a nice finish. He gave me one that he made and I use it many Sundays in our church.

rimar2000 (author)Phil B2011-10-07

Thanks, Phil!

Are you sure that all stainless steel alloys are diamagnetic?

Some weeks ago I found a large sheet of stainless steel during my bicycle rides, but I could not carry it to my house because it was too big and I had no way to cut a slice. It was a little wrinkled, but that is easily solved.

That "friend" that burned my grinder, killed the goose that lays the golden eggs, I never lent him a tool another time.

embochner (author)2011-10-06

de donde secaste un eje de rotor?

rimar2000 (author)embochner2011-10-07

Hola embochner, lo cuento en la intro. La amoladora andaba fenómeno, la presté y ¡la usaron para emparejar todo un piso de madera! Dijo basta, la pobre. Detesto a la gente que no cuida lo ajeno.

Hello embochner, the story is in the intro. The grinder was walking phenomenon, I lent it and they used it to match all the hardwood flooring! It said no more. I hate people who do not care what belongs others.
