In the picture above are common components used in the head assembly of clubs to help maintain a straight and tight fit between the shaft and hosel.
A. Glass Shafting Beads - these are the most commonly used during club head assembly and allows the builder to take out minimal gaps between the shaft and hosel to create a tight fit. Typically mixed into the epoxy to spread evenly through the hosel while the shaft is installed.
B. Quick Center - larger pieces vs the glass beads these are used to fill in gaps between the hosel and shaft that may be too small for shims but glass beads are unable to stabilize the shaft within the hosel. Unlike the beads though these are better applied by sprinkling onto the epoxy on the shaft tip then installed into the hosel to fill in and stabilize the build.
C. Ferrules - in the picture the two ferrules are both .355 ferrules at 3/4” length although one is collared and the other is not. This allows the stabilization of shafts at the entrance of the hosel when designed to by the manufacturer and helps ensure a straight installation into the club head.
D. SHIM-T - this shim is designed to allow .355 taper shafts to be directly installed into a .370 hosel and ensure a snug fit. Different from the SHIM-15 as it is shorter in length as the taper of the .355 shaft enlarges to .370 after a short span up the shaft.
E. SHIM-15 - designed to allow .335 shafts to be installed into .350 hosel. Scenario would include newer model wood shafts being installed older wood heads. (Can be trimmed to create SHIM-T shim to reduce needed storage or space)
F. SHIM-30 - designed to allow .370 shafts to be installed into .400 hosel. Scenario would include older large hosel iron heads being retrofit with newer iron shafts.
G. SHIM-65 - less commonly used but made to install a .355 shaft into a .400 hosel.
H. .355-.350 Ferrule - used to retrofit older wood heads with newer shafts. Creates a all in one fix rather than a two part fix. Can also be trimmed down as a great collared ferrule for woods.
When using the shafting beads and quick center it is important to use as needed and not overdue as to avoid weakening the epoxy.
When using shims make sure to clean and prep all sides of the shims as well as apply epoxy on all surfaces to ensure a correct epoxy bond.
