        The wedge offers a bit more rigidity and repeatability, but for the home shop, the piston will do fine. The money saved can be put to good use buying more toolholders.

          Another vote for wedge. Better repeatability, and reduced vibration because it locks in the toolholder better.

            # 5 in favor of the wedge type.

            Not being sarcastic, search the archives for views on each type. This topic has been brought up several times.

                The major advantage of the Aloris style toolpost is its mass and rigidity and the speed of tooling changes. Both styles offer these advantages.

                For the home shop, the difference between the wedge and piston is minimal, and probably not noticeable under routine use.

                If dead nuts repeatability is needed when changing tooling, as in a production situation, the wedge is the way to go. Otherwise, the decision is as much economics as practability.

                  wedge is the only way to go. i have the piston type pull away a little with heavy cuts.
