Our Double Handled Burnisher is primarily for flute headjoint fitting. This can be used with our JLS Flute Head Fitting Mandrel.
With the headjoint mounted on the fitting mandrel, select an area to work, and rotate this to the top and center. With moderate and even downward pressure, push the burnisher towards the vice. After 3 or so moderate strokes, blend the area with surrounding areas by burnishing with a lighter pressure. Then view the tenon from the end to check for roundness. You may also use our plug gauges for this. When final fit is arrived at, dress the tenon with 600 grit paper, then 3200 grit Micro-Mesh™. This may loosen the fit a little bit, so it is best to burnish until it is snug.
Always be sure the surfaces of both the work piece and the burnisher are free from dirt, oil, and dust. Polish the burnisher to remove any defects. I recommend Micro-Mesh™ for this, but you may also polish with Tripoli. Be careful of heat buildup – the plastic handles can be damaged.
