Introduction: Trona Para Mi Sobrina- High Chair for My Niece

Hola a todos.

Tenia ganas de hacer algo distinto, y un dia me propusieron hacer una trona, para mi sobrina. El material de base, como siempre, es la madera de palet. Supone un reto. Nunca habia hecho una silla, y la madera de palet no parece tener las dimensiones adecuadas. Las tablas de palet son mas finas de lo que necesitaba, asi que tenia que buscar una solucion.


Hello everyone. I wanted to do something different, and one day I was asked to make a high chair for my niece. The base material, as always, is the wooden pallet. It is a challenge for me. I've never done a chair, and wood pallet not seem to have the proper dimensions. Pallet tables are thiner than I needed, so I had to find a solution.

Materiales:

-Madera de palet

-Siera de mano (no dispongo de elctricidad en este taller)

-Tornillos, cola y espigas de madera.

-Formones, destornillador, mazo, cepillo de madera, lima, lija y lana de acero.

materials:
- Wood pallet

- Hand saw (I do not have electricity in this workshop)

- Screws, glue and wooden dowels.

- Chisels, screwdriver, wooden mallet, wooden brush, lime, sand and steel wool.

Step 1: Como Hacer Las Patas Y Las Uniones- How to Make the Legs and Joints.

Mas adelante veremos los planos, hechos a mano, y se entendera un poco mejor lo que voy a explicar a partir de ahora.

Para solucionar el problema de las dimensiones de las tablas, he cortado las tablas con las dimensiones de las patas. Para darle el grosor adecuado, he puesto dos tablas juntas, que encolare posteriormente. De momento solo las atornillare. El motivo es que quiero "cajear" las patas, de forma mas comoda, casi todas las uniones se podran hacer con sierra. En la segunda foto se ve la idea. Para unir el travesaño con la pata, basta con cortar una de las tablas, con las dimensiones del travesaño.

Later we will see the planes, made by hand, and it shall be understood a bit better what will explain from now.
To solve the problem of the size of the tables, I cut the boards with the dimensions of the legs. To give the right thickness, I put two tables together, that I'll glue later. Currently only use screws. The reason is that I want "mortising" legs, more comfortably, almost all unions can work with saw. The second photo shows the idea. To join the bar with the leg, just cut one of the tables, with the dimensions of the bar.

Step 2: Como Hacer Las Mortajas-How to Make the Motise.

Aqui podemos ver en estas fotos, si serramos una de las tablas, tenemos una caja con el mismo ancho que el travesaño. Si la caja hay que hacerla con formon, al hacerla en una sola tabla, hacemos un agujero pasante, que es mas comodo de hacer. Aqui ya se ven los tronillos retirados, y sustituidos por espigas de madera.

En algun caso, las mortajas seran uniones a media madera, por estar entre dos tablas. Y al unir las dos tablas se crea la mortaja, donde se introducira el travesaño a modo de espiga.

Por dejarlo claro, se hacen los cajeados, y cuando ya esta todo correctamente hecho, se retiran los tornillos y se encola. Mientra seca la cola, se mantienen los tornillos, y cuando ha secado la cola, se quitan los tornillos y se ponen las espigas de madera.

Here we can see in these pictures, that if we sawed one of the tables, we have a box with the same width as the transom. If the box has to be done with chisel, to make it into a single table, do a through hole, which is more comfortable to do. As shown, the screws are removed, and replaced by wooden dowels.
For it clear, the mortise are made, and when everything is done properly, the screws are removed and the tables are glued. While the glue dries, the screws are kept, and when the glue has dried, the screws are removed and wooden dowels are placed.

In some case, the mortises will be half-wooden joints, being between two tables. And when the two tables are joined, the mortise appears, where the transom will be introduced as a tenon .

Step 3: Ejemplos De Uniones- Examples of Joints

En la primera foto, se hace la caja en una sola tabla. Se cortara con sierra, y se retira la madera con formon.

En la segunda foto, haremos dos uniones, como si fueran a media madera, una en cada tabla. Es decir, retiramos la mitad del grosor del travesaño en cada tabla. Esta se hara con formon.

En la tercera foto, se ve claramente como se une el travesaño delantero, y el lateral entra en una mortaja pasante, que tiene a la otra tabla como cierre de la mortaja.

Estoy seguro que se entendera muy bien, cuando se vean los planos.

In the first picture, the mortise is made in a single table. It is cut with a saw, and chisel excess wood is removed
In the second picture, we will make two connections, as if they were a half-wooden, one on each table. That is, we remove half the thickness of the crossbar in each table. This will be done with a chisel.

In the third picture, it is clearly seen as it joins the front crossbar, and the side enters a mortise through which has the other end of the table as a mortise.

I'm sure you will understand better, when you see the plans

Step 4: Una Modificacion- a Modification

Como podeis comprobar, inicialmente no habia estas escudras en los travesaños. Despues de una primera prueba de campo, con la niña que la va a usar, vi que se movia lateralmente.

Estudiando las diferentes opciones que habia, que no fueran escuadras metalicas, me decidi por esta opcion. Algunas son faciles de hacer, ya que solo hay que hacer una escuadra, y hacer unos agujeros con la inclinaion necesaria para atornillar la escuadra al travesaño. Pero otros se complican. hay que hacer un corte especial, para poner la escuadra, y que no salga fuera de la pata.

As you can see, these squads had not initially on the crossbars. After a first field test with the girl who is going to use, I saw moving laterally.

Studying the options he had, other than metal squads, I decided on this option. Some are easy to do, just have to make a square, and make holes with the inclination necessary to screw the bracket to the transom. But others are complicated. To do a special cut to put the squad, and do not go outside of the leg.

Step 5: Como Hacer Las Escuadras De Refuerzo- How to Make the Squads

Para hacer los cortes, uso una sierra japonesa. En las escuadras "raras", se hacen dos cortes. Primero se corta el final, para dejar la punta con el grosor de la tabla de travesaño, y luego cortar por la mitad, para que el grosor no sea superior al de la pata.

Tambien hay que hacer los agujeros inclinados, para los tornillos. Los hago con una barrena de mano.

To make the cuts, using a Japanese saw. In the "rare" squads, two cuts are made. First the final cut, to leave the tip with the thickness of the cross table, then cut in half, so that the thickness does not exceed the leg.
We must also make inclined screw holes. I make them with a gimlet.

Step 6: El Asiento - the Seat

El asiento esta hecho con restos de tarima machiembrada. Aqui, la unica dificultad es, hacer coincidir las testas de las patas, con los cortes que hay en el asiento. Al embutir el asiento, mejora la rigidez de la estructura.

Tambien se atornillan a los largeros.

The seat is made with tongue and groove flooring remains. Here, the only difficulty is to match the heads of the legs, with cuts that are in the seat. By pressing the seat, it enhances the rigidity of the structure. And it seems to be working.I also screwing the seat to the cross bars.

Step 7: Reposapies - Footrest

La unica parte metalica en toda la silla. Un refuerzo para el reposapies. Esta hecho con una pieza reciclada de impresora.Me encanta reciclar cosas. Pero al final, por seguridad, le he puesto dos escuadras metalicas, para evitar el cabeceo del reposapies. Creo que la imagen explica muy bien como se pone, y porque.

The only metal part in the entire chair. Reinforcement for the footrest. It is made with a recycled printer part. I love recycling things. But finally, for safety, I've put two metal brackets to avoid pitching footrest. I think the picture explains very well as it gets, and why.

Step 8: La Coleccion De Planos Caseros - the Collection of Home Plans

Y aqui os dejo los planos que he hecho de la silla. La logica dice que primero se hacen los planos y despues la creacion. En este caso ha sido justo al reves. Hice la silla, y despues los planos, para poder explicar mejor la construccion de la silla.

Los voy a dejar en formato pdf tambien, para tenerlos juntos.

Espero que se haya entendido bien, y que la traduccion tenga pocos errores. La traduccion me ha dado bastante trabajo, espero que os sirva, sino, la culpa es del translator.


And here you have the plans, I've done, from the chair. Logic says that plans are made first, and then creating. In this case it was just the opposite. I made the chair, and then the plans in order to better explain the construction of the chair.
I'll leave, too, the planes in pdf format, to keep them together.

I hope you have understood correctly, and that the translation has few mistakes. The translation has given me a lot of work, I hope you like, but if have mistakes blame the translator.

Step 9: Acabado Final - Finishing

Como final, dejo una foto del acabado que le he hecho a la silla. El proceso de pintado y acabado, lo explicare en el proximo instructable. Entiendo que son temas distintos, que el uno es independiente del otro, por eso hare otro tema.

Siempre podeis ver algun detalle mas en mi blog Yo me lo construyo,

Tambien podeis ver algun otro trabajo, que ire subiendo aqui, pero mientras tanto, estan a vuestra disposicion en ese blog.

Espero que os haya gustado, y que sea de utilidad para alguna persona. Agur.


As a final, I have a photo with the finish I made to the chair. The process of painting and finishing, I will explain in the next instructable. I understand that they are different issues, which is independent of each other, for this reason I will make another instructable.
Whenever you can see some more detail in my blog "I built it myself."

Also you can see some other work, I'll go up here, but meanwhile, are at your disposal in this blog.

I hope you liked it, and it is useful for someone. Agur.

Your family must be very proud of you, and you built all by hand, I forget how lucky I am to have all power tools. and even then I rarely get the finish that you have achieved with this chair. Good on you and keep these wonderful projects coming. Thank you.

I hope so, but sometimes I think that the family look at me weird. Especially when I say that of "I'm here ..." while I looked through the door.
Seriously, I'm sure we all do. There are things they like, and some a little less. But what we really like is to do.
I also have electric machines, but in the garage where I do some of these things, I have no electricity. At first it was a nuisance. But over time, you realize how nice it is to use hand tools. And it does not take much more, to do the same job.
Thanks for the comment, and forgive the speech I have released you. (Almost all the bad translation google's fault ...)
