The number listed in the chart below tells the size of the mandrel. The first two numbers indicate the thread pitch and the last two numbers indicate the diameter in 64ths of an inch.
NOTE: In most cases you will need at least two P100 Mandrels to repair damaged threads. One mandrel will be the actual size of the horn as listed below and the second will be smaller or larger depending on the type of threads.
1 size larger for external thread or
1 size smaller for internal thread
As an example, if you needed to repair an All Star cornet, you would order one P100 in size 3651 and the second in size 3652. If the size you need is not listed on the charts, Ferree's will make it for you. As always, our customer service people will be glad to help you. These mandrels may be ordered individually or more economically in sets of 10.
