Description
Description
Ferrees Flute and Piccolo Head Swedging Dies were designed to shrink the tenons that have been over expanded. These dies can also be used to remove ridges and dents from tenons that have been previously improperly repaired. The proper sized die should be firmly held by a vise. Use cork grease or Z6 Synthetic Lubricant laced petroleum jelly as lube on the tenon. Tighten the adjusting screw so the die barely closes on the tenon. Work the tenon. Then move it back and forth in the die with a semi-rotating motion. Test fit, often.
