Here's a review of this tool on YouTube: https://www.youtube.com/watch?v=MXO_jLHvm8Y&t=3s Please read the print settings section below for important tips --------------------------------------------------------------------------------- This is version R1 of my guitar fret wire bender. It is a tool used by luthiers (guitar builders) to bend guitar fret wires to a specific radius. This model is based on a very common design known by most guitar building enthusiasts. A well-known drawback of the original design is its inability to curve the ends of the wire correctly. An additional, adjustable center roller was added to this design to counteract that. The usage of the tool should be self-explanatory but basically: You set the radius by adjusting the height of the lifter via the lower thumb screw. The top thumb screw is used to lock the height in place. *Note: Tightening the lock screw may end up raising the lifter a bit due to backlash. You can compensate for this by always setting the radius moving the lifter downwards.* You can also use this tool to straighten a fret wire. For this, you simply pass the wire along the main roller and then in between one of the lower rollers. *I just found this great tip on a YouTube video myself. Search for "how to use a fret bender" on YouTube if you need more information*. Additional hardware that you'll need to assemble this model: - 1x M8x60mm Hex Bolt - 2x M8 Nuts - 1x M5 Nut - 2x M5 Washers - 4x 625ZZ Bearings - 2x M5x20mm Bolts - 2x Adjustment Knobs To assemble the tool, follow these steps: **Lifter Assembly:** Insert one M5 nut into the Center Wheel Knob and make sure it sits flat at the bottom (*you can use a long M5 bolt as a helper*). Slide an M5 washer onto the wing bolt and then insert this through the long slot in the lifter through the side that faces the handle. Add another washer, then two 625ZZ bearings. **Main Body Assembly:** The upper portion of the main body has two slots that fit M5 nuts. Insert a nut on each slot making sure that they're angled correctly (*you will see what I mean if you look into the body*). Push them far enough in that you can see the center of the nut when looking through the bolt hole. **Final Assembly:** Secure the Top Body onto the Main Body with the M5x40 metric machine bolts. Tighten until the top of the screws are flush. (*You can also use regular hex bolts with an M5 washer*)
