panel pin การใช้

The three pieces of timber that form the mitre box are nailed together, and the top steadying pieces are fixed with smaller panel pins.
Skew nailing is also a technique used by other woodworkers, for example a drawer or box can be glued and skew-nailed with finer nails or panel pins.
Many panel pins were not connected to the structure at all and many of the bradawl holes necessary to equalize pressure between the inside of the wing and the outside were missing entirely.
It was designed and built by the Wrought Iron Bridge Company ( WIBCO ) of Canton, Ohio as an eight-panel pin-connected through truss in an unusual double-intersection Pratt design.
