Rotary Broaching Eccentric Cams || INHERITANCE MACHINING

Video Description

Welcome back to the machine shop for the dramatic conclusion to the rotary table chuck adapter build! Two videos ago I went about the process of reverse engineering the D1-5 cam mechanism of my metal lathe and developed an adapter design using the drafting table. Then in the last video I underwent the emotional rollercoaster that was machining the main body. So in this video I’ll be finishing up the remaining bits and bobs to make the mechanism work. Along the way I’ll be trying a few new techniques including scallop milling with the boring head. Turning an eccentric cam profile with the 4 jaw chuck. And one of the biggest side projects to date, making my own rotary broach to machine square holes! #inheritancemachining #machineshop #hobbymachininst Patreon (Early Access + Ad Free + Drawings) - https://www.patreon.com/inheritancemachining Drawings Store - https://inheritancemachining.com/?product_tag=drawings Instagram - https://www.instagram.com/inheritancemachining/ Website - https://inheritancemachining.com/ Amazon Storefront (affiliate links): https://www.amazon.com/shop/inheritancemachining And a special thanks to my "Micrometer" level patrons!
