27-02-2017: Rotary Broach and Chamfering machine builds
Readers of my website and the german webforum I frequent have shown their versions of the chamfer milling machine I build back in 2015 - I got permission to show their pictures on my website:
Chamfer milling machine - Versions

Using a set of plans from Heminway Kits I built a rotary broach that allows to machine internal profiles with sharp corners like a internal hex or square for a screw head.
The build is documented here: Rotary Broach
