Rivets:



Solid rivets
rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite to the head is called the tail. On installation, the rivet is placed in a punched or drilled hole, and the tail is upset, or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place. In other words, the pounding or pulling creates a new "head" on the tail end by smashing the "tail" material flatter, resulting in a rivet that is roughly a dumbbell shape. To distinguish between the two ends of the rivet, the original head is called the factory head and the deformed end is called the shop head or buck-tail.
Because there is effectively a head on each end of an installed rivet, it can support tension loads. However, it is much more capable of supporting shear loads (loads perpendicular to the axis of the shaft).
Fastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term rivet was introduced and, where they are remembered, are usually classified among nails and bolts respectively.





Tools Used in Project:
Cutter:



Hammer:


Angle Plates:

Making of Tool Trolley Boxes

Selection of Steel:
In this project, we used 28-GAUGE Steel Sheet. Because 28-gauge sheet is flexible and easy to bend and work with it.
Reason of Using this Steel:

  • Rust-Proof

  • High Strength


Measurements:
Length: 15-inches
Height: 2.5-inches
Width: 7-inches
