Click on the photo above to design a 12.5" swing-flat base Clark Steady Rest with arm configuration and color of you choice. The photo shown has 3 equally spaced arms, but they are rotated to place the 2 o'clock arm at 1 o'clock. This moves the upper arm out of the way of a hollowing system laser. This one comes with the standard flat base. It uses a 16" diameter ring and fits 12.5" swing lathes.
