Materials & Tools Needed
# Materials:
1. Frame:
– Heavy-duty steel tubing or angle iron (for rigidity).
2. Crushing Mechanism:
– Steel plates or hardened steel jaws (for durability).
– Hinges or hydraulic/pneumatic cylinder (for force application).
3. Drive System (if motorized):
– Electric motor (1-5 HP, depending on crushing needs).
– Pulleys/belts or gear reduction system.
4. Fasteners & Hardware:
– Bolts, nuts, washers.
– Bearings (for rotating parts).
# Tools:
– Welder (MIG/TIG/Arc)
– Angle grinder/cutting tools
– Drill & metal bits
– Measuring tape & square

Step-by-Step Construction Guide
# 1. Design Your Crusher
– Decide on the type:
– Manual lever crusher (hand-operated for cans).
– Motorized crusher (for heavier scrap).
– Sketch a simple diagram with dimensions.
# 2. Build the Frame
– Weld a rectangular frame from steel tubing/angle iron (~2″x2″ recommended).
– Ensure it’s sturdy enough to handle crushing forces.
# 3. Crushing Mechanism

## Option A: Manual Can Crusher
– Cut two steel plates (~¼” thick) as crushing jaws.
– Attach one plate to the frame (stationary).
– Attach the seco.jpg)
plate to a lever arm with hinges.
– Add a handle for leverage.
## Option B: Motorized Crusher
– Use a rotating drum with protruding teeth/blades to shred metal.
– Connect the drum to an electric motor via belts/pulleys.
– Include a hopper for feeding scrap metal.
# 4. Assembly
– Weld all parts securely; reinforce stress points.
– For motorized versions, align pulleys/belts properly.
# 5. Safety Features
– Add a protective cover over moving parts.
