Here's some photo's with my filing rest. The rollers are commercial hardened drill bushings right from MSC. The remainder of the parts are from the lucky bin including the micrometer head and bracket. I have two commercial hardened washers and a 3/8-40 thread on the roller spindles along with a 3/8-40 set screw so that I can set the axial end play to as close to zero as I can.
The indexing head clamps to the OD of the spindle seal housing. The two levers are for cotters as described by George Thomas in his books. With both cotters loose and the ball end of the index pin in a index hole, I can still rotate the spindle through about 90 degrees. Once I lock the large post cotter, the index is locked and I can index any multiple of holes from there until I lock the index pin with the other cotter.
