Making an indexing attachment for the lathe

In this video I design and build a universal indexing attachment for the lathe utilising an expanding mandrel and some 3D printed index plates. This I will be using in future videos to machine the graduations needed for dials etc. This design should work on most lathes with a hollow spindle bore and will be sharing it with my Patreon supporters; Check me out on instagram; Timestamps 0:00 Introduction 0:17 What problems do we need to solve? 01:10 Design 02:59 Machining the expanding mandrel 10:53 Drilling the bolt hole pattern 12:45 Milling the slots 14:23 Making the standoff 14:42 Making the cone 15:25 Indexing plates 16:23 Installing and use 18:08 Testing 19:54 Conclusion
