Poser uses a much smaller world scale than Max so the first thing that I did was to scale and position gauntlet1.obj onto a fully zeroed V4 figure. I then exported the gauntlet as gauntlet_scaled+positioned.obj, deleted the one in the scene, then reimported gauntlet_scaled+positioned.obj with none of the import options selected. The gauntlet arrived into the scene correctly positioned and at 100% scale. This will prevent the gauntlet "flying off" when unparented.

Next I used the Poser menu Object > Change Parent and parented it to the right forearm. I selected the option to inherit the bends of the parent. This initially resulted in adverse deformation when the arm was bent. The solution is to select the gauntlet in the scene, open the Joint Editor window, select the bend (yRotate) joint from the top drop down menu, then deactivate the spherical joint zones.

See gauntlet.gif for an illustration.

Hope that helps,
