SIZING YOUR BUTTON POST

MEASURING INFORMATION
 (please read and understand all instructions before proceeding)

1) If planning to install tuning rollers on a stringed instrument,

detune instrument to remove all tension from the machine head.

2) Using a small screw driver (use proper screwdriver head + or -),
c arefully remove existing button screw.

3) Gently pull button from button post while being careful NOT TO
remove any  existing plastic and/or metal washers.

4) Measure flats on the button post with a caliper, or similar device/tool
used to measure small increments, to determine size of roller needed*.

5) The following measurements pertain to listed roller sizes:
9/64" (.1406) = medium
5/32" (.1563) = large


*In a pinch, the notches found on your average box cutter blade can be used 
to detemine the size of the roller you require. If your button post fits very tightly into
the notch, you'll need to order a medium set of rollers. If your button doesn't fit into

the notch,  you'll need to order the  ​large rollers. If your button post fits loosely into the notch,  please contact us for assistance.
