Mill, Lathe and other ATM Helpers

Here is a collection of a few things I machined or handcrafted with more or less success. But that’s the story with ATM. While you doing something you also learning something. Unfortunately sometimes you had to learn more than expected.  Here I list the this which run well. But be careful: This are no simple instructions. You do everything at your own risk!

Mechanical stuff
