"Today in history", September 11, 2001 The events are regrettable, but I am not prepared to observe a moment of silence for this.

On 11 September 1492, King Ferdinand II (Emperor Ferdinand I), then King of Aragon, later King of Spain (one of the two kings) and Emperor of the United Iberian and American Empire (one of the two emperors), was ...... in his bedroom in Barcelona Manufactured and successfully test-fired the first revolver in human history, the predecessor of the flintlock pistol.

The revolver was expensive, inconvenient to maintain and repair, and the confinement of the ruling class, so it could not completely replace the arquebus. It was only in use for more than 50 years, but it became the founder of the flintlock pistol that followed.

The revolver was invented in 1515, so the technology could definitely be made in 1492, but Ferdinand was DIY this time...... It is said that the attack on the polar bear on this day in 2001 commemorates this great day 509 years ago......

On August 15th, Ferdinand began to scavenge for materials and oppress craftsmen (many processes cannot be done by themselves, otherwise the progress will be too slow), and on August 17th, he and Isabella separated and began to manufacture in the bedroom according to the introduction of Baidu Encyclopedia.

"In 1992, I began to conceive and design a pocket-sized craft gun based on the 16th-century British revolver, and completed production in 2003. The prototype gun absorbed the styling characteristics of the German revolver lighter, but the layout of the trigger and revolver was offset in the direction of the muzzle, the transition connection of the external lines was smoother and smoother, and the overall shape was more elegant and generous. The rope pattern on the edge of the runner cover and the primer plate form a ribbon wreath, the shape is elegant and solemn, the nose in the shape of a bird's head pear pillar is delicate and spiritual, the spindle-shaped trigger and the trigger retainer decorated with lace exude a classical atmosphere, and the shape and light and shadow changes of the butt are very rich, which has excellent ornamentality. The overall shape of the gun can be called the best in the revolver lighter pistol, and the pocket craft gun made by the author based on the gun won the "First Chinese Folk Art Boutique Expo" Excellence Award.

The craft gun is made up of 56 parts and can perform 8 actions:

(1) The bottom fire plate cover can be opened and closed; (2) The rotating head chuck bolt can clamp the flint; (3) The nose can be positioned in the standby and safety position; (4) Use a wrench to rotate the runner shaft to demonstrate the winding action; (5) The ejector lever can be used to push the ejection load; (6) The trigger retainer can be fired by pressing it; (7) The push lever can be withdrawn; (8) The cap of the gunpowder bottle can be opened.

Craftsmanship and steps

The production of the Pocket Craft Gun is carried out in 5 steps:

(1) Formulate processing technology;

(2) Prepare materials according to design and process requirements;

(3) Prepare tools according to the production process;

(4) Handmade;

(5) Assembly and commissioning.

To make this pocket craft gun, the author first worked out a reasonable processing technology. For example, in the production of the runner winding wrench, due to the small size of the workpiece and the cylindrical part of the wrench, the hand twist clamping is used to make it, which is both firm and convenient for rotating the roller file. However, if the material is cut according to the actual size, it must be clamped inverted in the processing, so that it is easy to clamp the surface of the workpiece that has been processed, so the blanking can be slightly longer, and the clamping handle is reserved. In terms of processing difficulty, the difficulty of the square hole is higher than that of the shank. In line with the principle of easy first and then difficult, the handle should be processed first and then the square hole. When processing, the copper rod is first clamped in the hand twist, and leaned against the wooden stake, swinging up and down with a flat file while rotating, rolling the file out of the shank, and then drilling the hole after the head file out the shape of the wrench.

Then use a sharp file to expand into a square hole, and finally cut off the shank for clamping. The method of adopting the reserved clamping handle has greatly facilitated the processing of the workpiece, and the method of holding the workpiece by hand twisting and utilizing the wooden pile to support the workpiece to rotate the roll file is adopted simultaneously, so that the machining accuracy of the rotating surface of the workpiece is guaranteed, and the method of drilling first and then expanding into a square hole makes the processing of the square hole simple and easy. The importance of machining technology can be seen from the machining method of the wrench, and a reasonable process flow can improve the quality of the workpiece and save time.

Next, it is necessary to prepare materials according to the design and process requirements, such as the model and specifications of brass plates, tinplate, steel plates, spring wires, and the variety and color of wood must meet the requirements in order to ensure the quality of parts.

After the raw materials are prepared, tools should be prepared according to the needs of the production process, mainly using 6 types of tools:

Measuring and marking tools - steel plate rulers, calipers, marking needles, sample punches, etc.;

Clamping tools - table vise, flat vise, hand vise, as well as various color pliers, hand twists, etc.;

Cutting tools - guillotines, scissors, carving knives, hacksaws, assorted files, taps, wrenches, electric drills, etc.;

Soldering tools – soldering irons, solder, flux, etc.;

Observation tools – magnifying glasses, microscopes;

Special tools – crank for winding springs, grooved plates and mandrel for rolling barrels, etc.

Directions:

(1) Barrel rolling

First of all, select the tinplate according to the requirements of the drawing, and after marking the line according to the size of the drawing, use the guillotine to cut the material. Then select the appropriate steel wire mandrel and the corresponding grooved plate according to the inner diameter of the barrel, clamp the tinplate between the groove plate and the mandrel bar, and use a wooden hammer to gently hammer it along the axial direction of the mandrel back and forth. Be careful not to use too much force each hammer to avoid hard breaks, and be careful not to scratch the surface of the tinplate. Finally, it is straightened and shaped by hand.

(2) Spring winding

According to the requirements of the drawing, select the steel wire used to make the spring and crank. Clamp the wire in the middle of the cardstock to expose your head, and then clamp it vertically to the table vise with moderate grip force. After clamping the fork at the front end of the crank handle, rotate the crank handle, and wrap the steel wire around the crank handle, and the number of turns wound is more than the number of turns required by the drawing. Because the spring will rebound after relaxing the rocker, the winding spring must be shaped and measured, and the parameters can be used only after the parameters are qualified.

(3) The production of a rotary lighter

Many parts of the runner lighter need to be carved, such as the rope patterns and decorations around the wheel cover and the inscriptions, etc., which are carved by hand, while the rotor shaft and the pear column at the lower part of the machine head are rotated and rolled by twisting the workpiece by hand. When the runner shaft is riveted and fixed after passing through the machine base, it should not be riveted to death, but should be able to rotate. The thread of the clamping bolt of the machine head chuck is made of tapping with taps and dies. According to international practice, the firing device of the pocket classical craft gun must cancel the firing function, so the gun did not make a lighter wheel, and the fire transfer hole between the primer plate and the chamber of the gun chamber was not opened, and only the action of the runner shaft rotating and winding was retained.

(4) The production of the butt

Before blanking, the butt should be made with tinplate according to the actual size, so that it can be proofread at any time when both blanking and engraving, which can not only ensure the processing accuracy but also save time. When blanking, the outer contour of the butt is roughly formed, and then the barrel groove on the upper part of the butt and the through groove on the lower part are opened, and then the receiver groove in the middle is chiseled through. Because the mahogany is brittle, when opening the cassette slot, a row of through holes should be made first, and then cut through with a carving knife. After the butt is assembled in place with the barrel, receiver, through barrel, and trigger, the pin hole is drilled and fixed with a pin. Then the shape of the butt is carved and a runner lighter and nameplate are installed. According to the style of the work, the butt is not painted or polished, but retains the original color and texture of mahogany. The gun does not use too much decoration, and the hand-carved inscriptions in the flower font are seemingly inadvertently elevated to the artistic taste.

The gun has two innovations in structural design: one is the open integral barrel receiver, which solves the problem of strength and safety; The second is the overall retainer trigger, which solves the problem that the trigger retainer of the previous pocket craft gun is too small, and the finger cannot reach into it to pull the trigger, and the gun can be fired by pressing the trigger retainer, achieving the perfect unity of shape and function. The gun is well proportioned, comfortable to hold and can be fired with one hand. ”

It's really taste that determines the height! In April, he was still lamenting Judas's unwisdom in Granada, but today he looks up to his predecessors in his bedroom.

“…… However, because there is no aiming device and the trajectory is relatively curved, it is more difficult to shoot, but it also creates a deeper shooting mood...... "Every time Ferdinand recalls this passage, he always feels that there are people outside the sky!"

"It's really profound! However, this kind of artistic conception is not something that a layman like me can enjoy...... "Of course, we have to add an aiming device!" I have slept less than 3 hours a day for more than ten consecutive days! Such a profound and subtle artistic conception is unblessed.

Fired a shot at the prepared improvised target, Ten Rings, no kidding, but it didn't miss the target.

The revolver could meet the needs of the next 50 years, but Ferdinand did not want to promote it. It took him so long to make it, although it wasn't a spear, but it was quite fulfilling, but he didn't want the army to use the weapons of this era, otherwise wouldn't he have to find Kivers in 20 years? He gained experience instructing craftsmen in the production of flintlock pistols.

Outside the door, Isabella knocked again, apparently strange about what she was doing, but fortunately she didn't think that the Assassin was responsible for the noise. Alas? Why don't you care about me so much......

Going out and giving Isabella a hug, Ferdinand excitedly went to meet the craftsmen he had recruited in the past few days......
