About

Videos about woodworking, homemade machines, wood-turning, making jigs, and more stuff from me out of my small basement workshop. I try to post one video a week or at least once every two weeks...but I don't really care about a fixed upload schedule because I produce my videos with a lot of editing. And I spend as much time as it takes until I think the video is finished. So yeah, I upload when I upload. You probably will see more videos about making tools for woodworking than actual woodworking projects...that's kind of my interest. About me: I'm just a 27-year-old German guy who just graduated in engineering. If you want to see project updates in between the videos, you can follow me on Instagram: https://instagram.com/marius.hornberger/ if you want to contact me: -via Email: [email protected] Wanna support me?
