Joseph Horner (remember him? we've reprinted some of his great material) explores "Turning Toolholders" in two large well-illustrated articles. You get a study of the lathe tool-holders used for turning, cutting-off and screw-cutting. You'll explore fixed front rake holders, fixed top rake holders, fixed top rake holders with swivel action, holders with top rake, cutting-off holders, screw-cutting holders, and forming-tool holders. Most of these I've never seen except in old articles. Many look like they might be worth fabricating for experimentation.
Finally you get an article teaching the production of square threads on the lathe which includes the tools, methods, and principles involved. More information worth having. Get a copy! 5-1/2 x 8-1/2 booklet 48 pages No. 23551 ... $7.95 |
