Milling machine stability assistance The Hobby-Machinist

2021-8-16  The machine might be rigidly attached to the floor, but where is the floor? And will it stay there? For the given situation, I would use some heavy angles attached to the top of the base and then level with the angles. The machine doesn't need to be level, but it must be true (no twist), and stable. The stability is the big issue.
