Parts of the Compact Bender


  • For detailed instructions on bending hooks, handles, and alphabet shapes, refer to the =instruction booklet provided by the manufacturer. (Paper copy available in the metal shop.)
  • Accessories are stored in a red bin stored in the metal shop. Accessories include seven round dies, 3 hitch pins, a right angle bending attachment, and a couple of shop-made replacement pieces (square stop block and a support pin).

Basic Operation Instructions

1. Check to make sure the screws attaching the bender to the shop-made mount are secure.

2. Place the mount on the lip of the acorn table.

  • The acorn table corner closest to the belt sander works best.
  • Make sure the mount fully engages with the acorn table’s lip. Tap down with a mallet if needed.

3. Choose the accessories appropriate to your operation and install them according to the Quick Set-up Guide.

  • The Square Stop Block creates curved bends, and the Right Angle Attachment creates angles.

  • The Support Pin lifts these accessories just enough to prevent interference with handle movement while bending the workpiece.

During set up, position the handle on the right side, up and out of the way. This will simplify roller installation.

  • Insert rollers and pins. Reserve the short pin for roller placement on the handle assembly. (See Quick Set Up Guide)
  • The Square Stop Block has four positions to accommodate the thickness of your stock.
  • Always place hole on the right in order to prevent the block from turning while the bend is performed.

4. Insert stock into bender, position it, and pull on handle to complete the bend.

5. Optional: For repeat bends, place stop pins into the ring located below the handle.

6. If needed, pins and rollers can be disassembled to remove bent stock from bender.
