Bob Loader's 4-jaw chuck

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:

Download part one of the plan as a PDF

four-jaw chuck plan side two

Download side two of the plan as a PDF

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.
