    How are you retaining the ER adapter axially to the headstock? Are you using any preload on it?

    Hello Steve and thank you

    No preload on this one as it has 4 bearings and they were a tight fit on the shaft , I cannot feel any lateral give so every thing is very tight but I have since
    made another ER32 and ER25 headstock but with a smaller 20mm shaft and with a larger bearing in both. Fitment is not quite as tight so this allowed me
    to place an rubber O-ring in between the rear pulley and bearing and preload set that way . Everything on these very tight with absolutely no measurable play .
