SKU: 110971 1x8 to 1-1/4x8 Spindle Adaptor

Spindle Adaptor - 1" x 8 to 1-1/4" x 8

These spindle adaptors are made of steel to adapt the lathe spindle to a different size. They have a hole going through the middle to allow them to be used with a vacuum chuck. They have flats on the sides so a wrench can be used for removing them from the lathe. They are sized by the female thread first and then the male thread size. So if a Powermatic lathe with a 1-1/4" spindle needed to be changed to a 1" x 8, then a 1-1/4" x 8 to 1" by 8 would be used. These spindle adaptors are made on CNC machinery for accuracy, however when using a spindle adaptor it is still not unusual to experience a small amount of run out due to cumulative spindle/adaptor error.
