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

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:
![Page 7: For Sale: Colchester Bantam Lathe and Accessoriesalekslabuda.com/sites/default/files/Colchester_Bantam_for_Sale.pdf · 1 For Sale: Colchester Bantam Lathe and Accessories Includes:](https://reader031.fdocuments.us/reader031/viewer/2022022419/5a7919b57f8b9a00168d39a5/html5/thumbnails/7.jpg)

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:
