This is a photograph of the first page of the instruction manual (included with the lathe). This lathe is the

Eagle model:

3. Electrical

The original motor was replaced by a GE motor that runs off 230V single phase:

Included with the lathe are the switch box and the 30 Amp breaker:

4. Test

A ¾” aluminum rod was held by the 5C collet chuck holder and a live center.

The original diameter was 0.74675”

It was turned down across one foot:

At one end, the resulting diameter was 0.74605”. At the other end, the result diameter was 0.74630”.

This implies that the slides are very parallel to the spindle, to within a quarter thou (0.00025”) per foot.

This also implies that the runout on the 5C collet is well below half a thou (because the full circumference was

turned down by less than half a thou).

The finish is also impeccable:
