Radius Turning Tool - part 9 (Completion & testing)

This is the final instalment of 9-part series. The need for this radius turning tool arose because I required a ball feature on the machinist's jack I am making in another series. As this project developed I realised that in addition to simple ball turning it would be good to add some other features such as machining close to a shoulder and the ability to turn internal radii. This video has two parts: In the first I complete the keep plate and make a detachable handle. The handle requires an interesting faceplate set up to machine a radius to the correct diameter and on a centreline. In the second half of the video the tool's functionality is tested in the following machining operations: 1. Turning a ball through 360 degrees - ie part off a completed ball 2. Turning a small diameter ball up close to a shoulder in steel 3. Turning a larger diameter ball in steel (1.5in) 4. Turning a radius on a corner 5. Turning an internal radius at a shoulder 00:00 Introduction to part 9 and remaining operations on keep plate 00:51 Using rotary table to radius keep plate 02:10 Taking a look at completed radius and screws for securing 03:02 Drilling and tapping table for M4 screws 03:44 Taking a look at efficiency of clamping of keep plate 04:34 Adding radiused profile to keep plate and tool holder 06:02 Design of the handle 07:52 Machining the curved surface of the handle bracket on a faceplate in the lathe 12:57 Milling a small radius on the handle bracket 13:29 Review of the completed handle 15:14 Profiling the front face of the tool holder for clearance 15:54 Test 1 - parting off a complete ball 19:19 Test 2 - machining a small ball close to a shoulder 21:31 Test 3 - turning a large diameter ball (1.5in) 24:30 Test 4 - turning a radiused corner 25:39 Test 5 - turning an internal radius at shoulder 26:07 Concluding remarks and next video
