Steelex Faceplate and Spindle Adapters

I received a Steelex 8-inch faceplate (D 1088) and a pair of inboard and outboard spindle adapters (D 1096 and D 1105) as a birthday gift. These were obtained from Amazon.com for substantially less than other sources (19.50 USD for the unthreaded faceplate, 7.80 USD for each adapter).

The adapter mounts to the rear of the faceplate and is held in place by three rather small hex head cap screws. I spun up the outboard side first and turned the lathe on at its slowest setting. A slight wobbling of the faceplate was detectable by eye and by feel. Ditto for the inboard side. For the sake of comparison, no such imbalance is detectable with my Nova chuck. I shall have to spend some time with these to determine whether or not a little shimming of the adapter will get it to run true.
