mala posta nº 5

Continuing the construction of the malaposta, I begin by showing how I make the two wooden molds for the construction of the side panels of the box, they are made of fiberglass, the doors are then trimmed well as the windows, these are made with glass of 1 mm and the frames in varnished mahogany wood, as in the original, plus some photos for better elucidation. I hope you enjoy seeing this progress.

 Formatting the wooden molds for the construction of fiberglass side panels

 clipping the doors and windows

How door windows are trimmed.

 windows already finished, interior and exterior, the glass is 1mm thick, the hoops are in varnished mahogany.

malaposta nº 5

Continuing the construction of the Royal Mail Coach No. 5, today I have finished the front wheel and all components associated with it, since this part is independent of the whole set, it is already tidy and also serves for the alignment of the rear wheels, here are some photos of this work, the next section will be the construction of the body, with prominence for the side panels, two wooden molds are made of these panels to format the parts with the curvature that they have.I hope you like to see this compilation of the work now completed.

malaposta 5

Following the construction of the carriage of the suitcase # 5, today I will show some more progress in the front wheel section, the 5th wheel, lateral arms reinforcements lateral, many, some welds are made of tin other silver, wood used it is all beech, it lacks the axle and supports of the springs to complete this entire set of the front wheels, plus some photos for better elucidation of this construction.

 The various phases of the construction of the front wheel.

malaposta 5

Following up, in the construction of the carriage of the malaposta of unknown origin, but with the number 5 engraved in the abutments of access to the interior, which in fact should be affixed in the doors, for an easier identification, because with the folded stirrups it is not possible to see the number of the carriage.
Well after all the measurements, photos, drawings and sketches, it is time to move everything to scale 1/10 and start work, here are some photos of this progress, already with the very advanced drawings and some parts in execution.

 The various phases of construction of the plans.

 construction of the yard where the whole structure of the carriage is fixed, already with the spars mounted to align the whole.

wheel construction

Today I finished the wheels of the carriage, they are ready to paint, as you can see already has the first coat of primer, to protect the wood and metal.
This carriage made very long and continuous journeys along roads with many holes, curves and inclinations, and the enormous weight it carried, so the wheels had to be strong, strong and compact, as you can see the rays are staggered to 3 and 7, which gives it great strength to torsion and traction shocks, the pins are also screwed to the wheel rims, thus reinforcing the whole set, in which each rear wheel weighed about 70 kg. particular attention was paid to these components of the malaposta carriages.
Some more photos from this compilation.
Given that this will be my last article published in this year 2017, I would like to wish all readers sincere wishes for a prosperous and healthy New Year. Jose. C. Brito.

 The hoops are silver-plated for strength

The spokes are staggered at 3 and 7 degrees, and the feloes are bolted to the rim of the wheel to give greater strength and solidity to the entire wheel assembly.

 In this image it is possible to see the scaling of the rays at 3 and 7 º.

 The various stages of wheel construction.

Jig to center and sharpen the spokes in the center of the wheel.
There were two components in the carriages, which the coachmen paid special attention to, the spear and the wheels, the first when it broke, the carriage was uncontrolled, and the wheels collapsed causing unpredictable accidents, each carriage of the original malaposta French, weighed approximately 1,900 kg. Empty, plus the passengers, up to 12, plus the mail load and other luggage, in total would be approximately 2,600 kg. That the wheels had to support along 300 km of the route between Lisbon Coimbra and Porto, for this reason the wheels of the carriages had special characteristics to withstand this enormous effort, to give an idea of ​​the robustness of these components, each rear wheel, therefore the largest, weighed between 60 and 70 kg, with the hardware, the cubes and the pines were made of hollywood, and with the semi-green wood, because in drought it was impossible to work it, had a behavior like iron , to give it even greater robustness, the rays were not symmetrical, but rather staggered at 3 and 7 degrees to the cube on the outside, in the investigations I have made in this respect, there are reports of, in the hottest months of the year I used to wrap a burlap soaked in water around the hub near the rays in order to keep the whole set more uniform and prevent the rays of the sun from falling on them, causing clearances and cracks and thus avoiding the collapse of the wheels. all the stations change a blacksmith's shop where they had spare wheels for all eventualities, the wheel axles were also lubricated with some regularity due to the great friction caused by the weight and great distances covered, the lubricants used were a mixture of oil with soap.
Regarding the wheels of this miniature that I am about to start, since they are very similar to the previous ones, I will not dwell on details, only the main parts that compose them, several people have approached me about the construction of the wheels, since it is a job that requires some skill and a lot of training, but here are some photos of this work.
