These precision made, polished and chrome plated, expanders have the proper internal expansion angle to give you a feel when you are fitting the job and alsohelp prevent scratching the internal surfaces. These tough long lasting steel tools can be held in your hand or in a bench vise. These expanders all work on the same principle. They make an even, tight fit from loose and worn sax neck tenons and metal flute head and foot tenons, by rounding out bent, dented or out-of- round tenons. These tools apply even pressure, from the inside out. OPERATION - Mount the tool in a vise using a V-block to properly secure it. Use cork grease as a lubricant on the working surface of the expander. Then turn the knurled adjusting knob until the expander is snug inside the tenon back and forth over the expander?s working surface with a slow semi-rotating motion.

Superb tool for achieving the perfect fit on both footjoint and head joint. No vice required, it was easy to use on solid silver...may require vice and extra torque for expanding metal alloy flutes. Make sure you apply cork grease to all surfaces of flute joint and tool before using
I use in conjunction with flute head swedging die to perfectly reshape damaged tenons. Make sure you check fit regularly as you can easily over do it. When you see the tool, you will understand and appreciate its cost...well worth it.
