Piezas de acción/ Action pieces

From the sketch the pieces which are going to perform the action are becoming real.

Tercer eje/ Third axis

Now I have three vertical axis, two with an oscillatory movement and one with rotary movement. From the side I have also axles with rotary motion.

Now I have to move to the stage to connect these axles to the outside of the truck. I wonder if it is not too complex for a simple automata and the answer is yes, but it is very funny.

For this last axle I added an eccentric cam with a follower and a steel bushing to reduce friction. I took this picture in color to make a change and to show the contrast between the steel and bronze bushings.

10 diferencias/ 10 diferences

This is interesting, I took this first photo in the morning and in the afternoon I took a second as backup where I discovered that now the anthers on the stamens opened and pollen grains are emerging.
Echeveria/ Echeveria

Since years I have this plant and this is the first time I see it blooming. I don't know the common name but now I learned that it is a succulent from the genus Echeveria.

Pieza misteriosa/ Mysterious part

A new part connected and ready to move the.....

Horizontal/Vertical

Again after a lot of work not big things seems to have changed but now the movement is reaching outside the truck.

Now I got the horizontal spinning became in vertical spinning to move an essential storm chaser accessory, which I'm not going to tell now, any guess?

Todo se junta ahora/ All together now

Small pieces start coming together in the mechanism box.

There are 4 pulleys, 2 belts, 5 axles, almost15 brass bushings, 1 cam, 1 bevel gear so far. I have enough movement to achieve various effects.

Pequeñas piezas/ Small pieces

This is the stage where a lot of work is done but it does not show too much progress until all these little pieces are together and working in unison.

Trabajando en el mecanismo/ Working the mechanism

I started to work on the internal mechanism for the truck and the decision was to make a metal box so I will not have to make a bushing for each axle.

The transmission of the movement is through pulleys, I made two, the small one will slow the rotation the other will increase it. The pulleys are made of wood on a brass bushing.

This pulley reduces the rotation to activate the cam which it will trigger the lightnings... yes ... lightnings.

El Cazador de Tormentas sobre ruedas/ The Storm Chaser on wheels

The truck for the Storm-Chaser is mounted on wheels. Today I finished the hubs to be welded to the wheels and cut the axes.

Ruedas para el Cazador de Tormentas/ Storm Chaser wheels

It took me a while thinking about how to make the wheels for my automata, finally I remembered how were the wheels of my Meccano set and I reproduced it embossing metal over a mold in the lathe.

I used tin plate from coffee cans which nowadays is very thin but welding two of them to form each side of the rim gives sufficient rigidity for the use they will have.

El Cazador de Tormentas/ The Storm Chaser
Thanks to the inspiration of Sergio's Pinese contest at Crankahead I decided to work on a new automata with the tools that I still have at hand.
Se va a llamar el Cazador de Tormentas. Es un pequeño camión equipado para perseguir tornados, tendra sus propias nubes en el techo y habrá algo de acción de rayos.
It will be called the Storm Hunter. It is a small truck equipped to chase twisters, it will have his own clouds on the roof and there will be some lightning action as well.

This is what is already built so far, during the week I will begin to work in the mechanism.

Mi primera Maquina Inútil 2/ My first Useless Machine 2

This Useless Machine was built in almost one day. I decided at the last minute to build a machine for the Crankahead contest. I didn't start earlier because I'm moving my workshop, all the machines are packed, but the new place is not ready, so I used just what I have at hand like these scrap pieces of wood.
El interruptor tiene una extensión para tener una mayor acción de palanca. Lo había comprado para esto y por suerte no estaba empacado.
The switch has an extension to get a bigger leverage action. I bought the switch for a proper useless machine and I was lucky to have it not packed.
La máquina tiene un mecanismo muy simple. Todas las partes son recicladas excepto el interruptor.
The machine is a very simple mechanism. All the pieces are recicled parts except the switch.
Estas son todas las partes movibles, un engranje de corona hace de reducción para mover el eje con hilo.
These are all the moving parts, a crown gear acts as reduction to move the threaded axle.
El motor fué reciclado de un juguete, el cable de una conección de computador, algo de soldadura de estaño, un alicate de punta y pegamento. Para terminar a tiempo tuve que olvidar toda la precisión de la ingeniería modelo.
The motor was recicled from a toy car, the cable was from a computer, some soft solder, a nose plier and some glue. I did have to forgot all I know of model engineer to finish this.
