Building the Rotary Broach from Hemingway Kits

Video Description

Want to make hexagonal or square holes? Then this is the perfect tool for the job. In this video I make the Compact Rotary Broach from Hemingway kits. I go through the full build process including a number of mistakes along the way! I also cover grinding hexagonal and square broaching tools with the D-Bit grinder. @StefanGotteswinter makes the same kit, his video is well worth checking out; https://www.youtube.com/watch?v=O2glVyU0_C0 Support the channel; https://www.patreon.com/joneseymakes Buy project plans, 3D printable items and merch! https://www.joneseymakes.com/ Check me out on instagram; https://www.instagram.com/joneseymakes/ Timestamps 0:00 Introduction 0:22 Looking at the kit 0:30 Making the locking ring 5:02 Making the shank 8:12 Tramming the head of the mill 10:41 Making the body of the rotary broach 18:30 Making the spindle 24.47 Cut angle in tool body 27:15 Making the cutters 30:49 Cutter sharpening jig 32:49 Heat treating the cutters 36:45 Aligning the tool 38:19 Finishing the tool body 39:13 Final assembly 40:00 How does a rotary broach work? 40:28 Testing the tool 41:32 Conclusion
