Spacer, Spindle 4 mm

Wasn't sure a plastic spacer would hold up but this one seated perfectly behind the chuck on my 7x14. The 5 mm keyway lines up with the spindle key without any filing, and the 4 mm thickness gave me just enough clearance.

Snug fit on the spindle shaft, and the 30.2 mm ID slides on without any wobble. The 4 mm thickness matched the gap I was shimming on my 7x14, so no extra washers needed.

The 5 mm keyway lined up perfectly on my 7x14 mini lathe spindle, no filing needed. I measured it at 30.2 mm ID and it slid on with just the right amount of snug. Finally got rid of the play in my chuck setup.
