I wanted to build a sound abatement enclosure for an Altmill MK2 2x4 system. I don’t have my machine yet, so I can not take direct measurements, but I was hoping that from users who do have this system, they could share what they think would be sufficient clearance and what the minimum internal dimensions need to be to support a spindle and dust boot over its full range of motion.

I was going to provide the same references as @MrExo3D but I was further going to suggest you wait until you get your Altmill and work with it a bit to determine your workflow. I moved mine a few times because I like having access to all four sides.
You really don’t want to build something now that will impose constraints on you later on.

Another user just posted about his enclosure here: Been hiding with an Altmil 2x4 build!
Another thing to consider when planning an enclosure is access to the rails and ball screws for maintenance tasks such as cleaning and lubricating.
Thanks for pointing that out
I too needed sound proofing for my cnc. I considered an enclosure but there seemed way too many challenges and problems with that approach. I instead sound proofed the entire room and I could not be happier. In a nutshell, I used 6” of rockwool, drywall, then 2” acoustical foam. I framed the door with 2x4’s, filled it with acoustical foam, 1/2” plywood on both sides, then 1” foam board and 1” acoustical foam on the inside. The door is a total of 7” thick. You can barely hear the cnc or the dust collector outside of the room. I can point you to some pictures if you’d like, lmk.
Thanks for the inspiration!
I’ve now created a similar sound proof basement room in preparation for the arrival of my own Altmill 2x4.
