This excellent design is by Bob Loader, who wrote many excellent articles on accessories for Unimat lathes for Model Engineers' Workshop. This chuck is designed to be made on the small lathe, so it has rather unconventional construction. The accompanying details are in issue 11 of Model Engineers' Workshop, June/July 1992, available in the online archive*.
This is a particularly pleasing plan to present as the resulting chuck is very neat and practical.
As usual, the full size plan is contained in these two lowres jpeg files and full detail accompanying pdf versions:
Alternatively, the plan can be downloaded as a series of overlapping printable Pdf pages which can be used to assemble a paper version:
As always, special thinks to Nick Farr for scanning the original.
We hope you enjoy this plan.
