as a tool user, controlling your tools, and keeping them from shaking is the key. but a heavy machine grinder should already be strongly mounted and braced. The drills are a slightly different story from normal tools. They would kick around like mules with bee filled sacks over there heads without being stabilized from behind. for the most part though, the modules themselves appear to have more than enough mass to stabilize their individual parts.
All of that doesn't answer my question. Watch these week's video that I linked. About half way through they talk about the server option for big tools shaking or not shaking and demonstrates what that looks like. Should we enable or disable this feature. I think as of today it's disabled.
What I ment by that up above, is the only reason these tools would shake in space, was because they weren't designed to be in space. There should be no shake.
