    Motor Trunion BT3100 - What is it?

    Hello,
    what is a/the trunion for the BT3100 motor? I know what one is for a firearm, but does anyone have an explanation and pic for my table saw?
    Thanks.

      A trunion in a table saw is the pivot point around which the saw makes its bevel cut - the tilt center.

          Actually the pivots are I believe #15 and they are small dowel pins, like a needle bearing.
