摘要

Following the modification of a drilling vice in the last issue the subject this time is another work holding device, an angle plate. This is an excellent size for using on a vertical slide and is made from a casting available from Woking Precision Models (ref. 1). No drawing is provided with the casting but in any case there is no real reason to work to any particular dimensions, just machine until you have a clean angle plate. Its nominal dimensions are length 3(7/8)in, wide face with three cast slots 2(1/2)in. and narrow face without slots 1(7/8)in. Photo 1 shows the raw casting together with the castings for a vee block and a small vice that will be the subjects for two further articles. Also in the photograph are four tee nuts largely made using the lathes turning facility, see Photo 1 in the introduction to the series, issue 108 page 12. As can be seen from the photos taken during manufacture of the angle plate, I have happily used the three jaw chuck to hold the milling cutters throughout. I am aware that some readers will frown upon this practice and insist on a purpose made milling cutter chuck. Suffice to say, that for the relatively light milling work undertaken in the lathe on this project, it worked for me, and does permit the use of tipped cutters, having shanks outwith the capacity of my milling chuck.
