What is required to install the insert into my existing shaft?
First you need to decide what basic length you want. The average length driver is 45 inches. If you wanted 45 as the shortest setting you would cut your shaft at 38 inches. After applying the insert you would have 45 to 52 inches for an adjustable putter. Because people will want different lengths our unit of measure is 1 thru 7 on the inner shaft. Therefore you might play at 31/4 for fast greens and 53/4 for slow, you get to decide. Basically you will cut your shaft, install the lower grip, sleeve the insert and add bonding agent included, and allow time to set up.
