One of the keep plate fixing screws also doubles as a jaw withdrawal device and needs a 4mm spigot turning on one end, also the length will be quite critical. Assemble, jaw, keep plate and feed screw and test the screw making adjustments as necessary. Should changes be necessary to the groove in the feed screw it will be easy to return the screw to the lathe for machining in view of the centre in the end.

 

Assembly

File the four corners of the base to remove the rough surface of the original casting, chamfer/debur edges and assemble and you have acquired a very useful small vice, Photographs 15 and 16.

 

Small toolmakers Vice

At the start of this project I commented that the casting may not be available but suggested that making a Toolmakers style vice from available castings would use many of the same setups. I also mentioned my preference for using a toolmakers vice in view of it being easier to position on the vertical and cross slides, also having a larger capacity. See  here for more of my  thoughts on this subject.

 

Photograph 15 shows the size of the toolmakers vice compared to that in this project and Photograph 17 a typical machining operation, compare this with photograph 2
