I think you will need to have your parents involved, both as interested parties, and as moderators. As I'm sure you are already aware, Asperger's can make clear communication all the more difficult, so having your parents there might help to keep things from going off track. And, it being their house and garage, they get to have their say too. You may have to try extra hard to appreciate the point of view of others, as that ability too is often affected by Asperger's.
Rereading your first few posts, I see language like "forced him to use..." and "guidelines that I will make them sign...". I know that I would not respond very positively to that sort of approach, would you? Just as the success of a woodworking project is dependent on the skills of the craftsman, the skillful communicator will have better results than the unskillful.
So, the skillful way to approach this would be to ask for their cooperation, and come up with a set of guidelines that everyone will follow - you, your parents, grandfather, and your younger brother. This will involve everyone's input, not just something that you hand them to sign off on. The needs of everyone else are just as important as you own.
State how you feel about what has happened to your projects without blaming the other person. This is called an "I statement" For example: "I feel angry when I come out to the shop and find my project on the floor with the finish ruined, or find my desktop banged up. What can we do so that I don't have to worry about my projects being damaged when I'm not around?" In this way, you invite them to be a part of the solution, rather than dictating terms, or blaming them for your feelings. They will be much more likely to respond in a helpful way.
Now, the solution may require you to make some changes too, like putting tools away, and keeping project parts out of harms way. The important thing is finding a solution, not maintaining all of your current habits, so be prepare to give some in order to gain some. Get used to it, because even as an adult you will have to do a lot of that, or else you will be spending a lot of time by yourself.
Something that nobody has mentioned yet, is that your grandfather's brain may not be working as well as it used to. He might be forgetful and not fully aware of the consequences of his actions. If so, it's not really his fault, it's just something that will happen to most of us if we get old enough. Some people may be affected at an earlier age than others. This of course is just a guess, and should be taken as such, but might explain something about his behavior and lack of judgment in handling your projects. If that is indeed the case, you will have to work around that, and take responsibility for the safety of your projects, as you won't be able to depend on his judgment. This might be something you should ask your parents about, to get their opinion on. Again, this is just a guess on my part, based on very little information, but it could be one explanation of what is happening.
Good luck on your quest.
