Complicated shapes de-complexified

Rich Wagner, of Tapco tools, demonstrates how to bend a J-Channel for vinyl siding from standard aluminum coil stock.

 

Here's how to do it:
  • Begin with a 3.25 inch piece of trim stock.
  • Slide it in and square the outer edge with the face of the moving hinge.
  • Bend it 135 degrees, and then hem it tight with the hinge.
  • Slide the piece in, finish side down still, squaring the inner edge of the hem to the edge of the hinge.
  • Bend up 90 degrees.
  • Slide it out so that the bent edge is square with the outside of the hinge,
  • Bend 90 degrees.

 

Rich bent this soffit miter in 35 seconds; can you beat him?
