Milling machine: For cutting receiver slots and trigger housing. Hacksaw: For cutting steel sheet, rod, and tube. Drill press: With 3 mm, 5 mm, 8 mm bits (for screw holes, rivets, gas port). Files: Flat and round, for smoothing and shaping. Grinding wheel: For sharpening and finishing metal parts. Welding torch: For joining receiver and barrel. Riveting tool: For securing rivets. Screwdriver: For screws. Hammer and chisel: For rough shaping. Vise: To hold materials. Caliper and measuring tape: For precision measurements. Tap and die set: For threading screws and barrel chamber. Wood carving knife: For shaping stock and handguard. Sandpaper: 80- and 220-grit, for finishing. Heat treatment furnace: For hardening steel parts (optional, but ideal). Bluing solution: For corrosion resistance. Step-by-Step Construction Step 1: Fabricate the Receiver Cut a 30 cm x 10 cm rectangle from the 2 mm steel sheet. Bend into a U-shape (10 cm wide, 3 cm high) using a vise and hammer. Use a milling machine to cut slots for the trigger mechanism (5 cm x 2 cm at bottom) and magazine well (6 cm x 3 cm, 10 cm from front). Drill 5 mm holes for rivets (4 on each side) and 3 mm holes for screws (2 for trigger guard). Step 2: Machine the Barrel Use the lathe to shape the 25 mm steel bar into a 40 cm barrel with a 7.62 mm inner diameter. Cut rifling (6 grooves, 1:10 twist) using a rifling tool or lathe. Thread the chamber end (8 mm thread) for attaching to the receiver. Drill a 3 mm gas port 15 cm from the chamber end. File and polish the exterior. Step 3: Create the Bolt and Carrier Lathe a 10 cm x 10 mm steel rod into a bolt with a 7.62 mm firing pin (1 mm tip). Cut a 5 cm x 10 mm rod for the gas piston. Weld the piston to the bolt carrier (a 10 cm x 2 cm steel block). Ensure the bolt slides smoothly in the receiver’s rails (file as needed). Step 4: Build the Gas System Cut the steel tube to 25 cm for the gas tube. Drill a 3 mm hole to align with the barrel’s gas port. Weld a 5 cm steel block to the tube’s front as a gas block. Attach the tube to the barrel with a 5 mm pin, ensuring gas flow from barrel to piston. Step 5: Construct the Trigger Mechanism Cut two 5 cm x 1 cm steel strips for the trigger and sear. File the trigger to a curved shape, drill a 5 mm pivot hole. Shape the sear to catch the bolt carrier. Attach both to the receiver with 5 mm pins. Add a 1 cm compression spring to the trigger for reset. Ensure the sear releases the bolt when the trigger is pulled. Step 6: Craft the Stock and Handguard Carve one wood plank into a 25 cm stock (ergonomic shoulder curve) and another into a 20 cm handguard to cover the barrel and gas tube. Sand both smooth. Attach the stock to the receiver’s rear with two screws. Secure the handguard to the barrel with a 5 mm clamp (cut from steel sheet). Step 7: Assemble the Magazine Bend a 15 cm x 10 cm steel sheet into a 30-round magazine box (6 cm x 3 cm x 10 cm). Weld seams. Cut a 10 cm x 2 cm aluminum strip for the follower, attach to a 5 cm spring. Insert into the magazine, add a steel baseplate. Ensure it fits snugly in the receiver’s magazine well. Step 8: Final Assembly Weld the barrel to the receiver’s front, aligning the chamber with the bolt. Attach the gas system, bolt carrier, and trigger mechanism. Rivet the trigger guard (cut from steel sheet) to the receiver. Test the bolt’s movement and trigger pull. Apply bluing solution to metal parts for rust protection. Step A: Loading the AK-47 Insert a 30-round magazine loaded with 7.62x39mm rounds (0.5 g smokeless powder, primer, 7.62 mm bullet). Pull the charging handle (attached to the bolt carrier) to chamber a round. Set the selector (a 5 cm steel lever, pinned to the receiver) to semi-auto or full-auto (adjust sear engagement). Step B: Firing the AK-47 Aim down the sights (notch rear, post front, cut from steel and screwed on). Pull the trigger to release the bolt, firing the round (~715 m/s). Gas from the barrel pushes the piston, cycling the bolt for the next shot. Semi-auto fires one round per pull; full-auto fires continuously while held. Step C: Reloading and Maintenance Remove the empty magazine by pressing the release lever (cut from steel, pinned near magazine well). Insert a new magazine. Pull the charging handle to chamber a round. After firing, disassemble (remove pins, separate barrel, bolt, and gas tube). Clean with a cloth and solvent to remove powder residue. Oil metal parts lightly. Check springs and pins for wear every 500 rounds. Quality Control Test-fire 10 rounds in a safe area to confirm cycling and accuracy (effective range ~300 m). Inspect for loose rivets or screws after 50 rounds. Ensure the barrel aligns with the receiver to avoid misfires. Replace worn springs or firing pin after 1,000 rounds. Notes This AK-47 is rugged but needs regular cleaning to avoid jams. Use only 7.62x39mm ammo with smokeless powder for reliability. Practice trigger control on semi-auto to conserve ammo.

Press: For forming cartridge cases and bullet jackets. Hacksaw: For cutting brass and steel. Drill press: With 3 mm and 5 mm bits (for primer pockets, vent holes). Files: For smoothing metal edges. Grinding wheel: For sharpening tools and molds. Vise: To hold materials. Caliper: For precise measurements (7.62 mm bullets, 39 mm case length). Bullet mold: Custom 7.62 mm mold (machined or purchased). Reloading press: For seating primers and bullets. Punch tool: For primer pocket shaping. Hammer: For shaping brass. Measuring tape: For cutting accuracy. Welding torch: For small joins (optional). Sandpaper: 220-grit, for finishing. Scale: For measuring powder (0.5 g per round). Step-by-Step Ammunition Construction Step 1: Form Cartridge Cases Cut 4 cm x 2 cm rectangles from brass sheet. Roll into 39 mm long, 11 mm diameter tubes using a mandrel (10 mm steel rod). Weld or press seams tight. Use a punch tool to form a 3 mm primer pocket at the base. Trim to 39 mm length with hacksaw, file smooth. Drill a 1 mm flash hole in the base. Step 2: Create Bullet Mold Lathe a 7.62 mm diameter, 25 mm long cavity in a steel rod, split lengthwise for a two-part mold. Polish the cavity for smooth bullet release. Step 3: Cast Bullet Cores Melt 500 g lead, pour into the mold to form 7.62 mm x 25 mm cylindrical cores. Cool and remove. Aim for 8 g per bullet (123-grain equivalent). Step 4: Form Bullet Jackets Cut 2 cm x 3 cm rectangles from copper sheet. Press into a cup shape over a 7.62 mm mandrel using the press. Insert lead core, crimp the copper jacket closed with the press. Step 5: Prime the Cases Insert a small rifle primer into the cartridge base using the reloading press. Ensure flush seating with the punch tool. Step 6: Load Propellant Measure 0.5 g smokeless powder (nitrocellulose-based) per cartridge using the scale. Pour into the case through a funnel. Tap gently to settle. Step 7: Seat the Bullet Apply lubricant to the bullet base. Use the reloading press to seat the bullet into the cartridge case, crimping the brass rim tightly around the bullet (7.62 mm diameter, total cartridge length ~56 mm). Step 8: Inspect and Test Check each round with caliper: 7.62 mm bullet diameter, 39 mm case length, 56 mm total length. Test-fire one round in a safe area to confirm ignition and velocity (~715 m/s). Step A: Storage Store rounds in a dry, padded box to prevent corrosion or impact. Step B: Quality Control Weigh 10 rounds (should be ~10-12 g each). Ensure consistent powder load and tight crimp. Test-fire 2-3 rounds for reliability. Pack 30 rounds in a padded metal tin.
