Brass Instrument Valve Casing Thread Repair Techniques
John Huth, Greg Beckwith, John Maddox
Using the bottom casing threads on a trumpet as the focus this video presentation, with question/answer period following, will address common thread repairs including correcting for out-of-round threads and damaged threads where the valve cap cannot start. We will show how to maximize the effectiveness of the Ferree's Thread Repair Mandrel and the Allied Thread Chaser. We'll will also broach casing thread grafts.
