So, I was given a lathe that had electrical problems.
I sorted those problems, and I am now looking for some simple projects so I can learn the machine. My first thought is to turn some clutch pulleys out of brass. Do you have other suggestions? Attached thumbnail(s) |

Making your own bushings is a handy skill. Turning(cryogenically) dry-ice or nitrogen frozen rubbers and plastics calls for hss tool grinding and diamond honing. Form tool geometry for those materials and some light metals requires high positive rake. A carbide ball tool in a die grinder can create a groove in the top surface of the hss shank,a kind of 'moat'. The relief flank is then ground to give a .005/.007" wide top face and positive chip rake. With some practice and a toolmaker's microscope,a <16rms finish can be achieved. https://www.google.ca/search?q=shadowgraph+...Rz1AvcQ_AUIBigB http://www.graphalloy.com/html/type_317.html / (edit:2/23/16) Generally,the use of old tech is cheap in terms of tooling costs,high in labour for the grinding of tungsten and cobalt HSS,or B-CARs. The first error with either tool type will destroy the tool and or part,forcing a restart from the beginning. A brand new indexable insert tool holder will allow some leeway for miscalculated feeds and speeds. Know what you are doing before the tool touches the part. https://www.google.ca/search?q=hand+grindin...BxuxkzkYIx6M%3A / |
