Review on Spindle Adapter 16 10 Arbor Polishing by David Pearson

I bought these for my benchtop polishers with 1/2" diameter shanks. Spindles fit with no problems. They are heavy, well made and hold the buffs well. There is no play or vibration. One thing that could be better; The spindles have two socket head screws to hold the spindle firmly on the shaft, but they are too far apart as only the first one touches the shaft. I would move the two head bolts closer together so they can be tightened on the shaft. One seems to work, but check it often to make sure it's staying tight.
