In my new new shop...

[Kevin Sjostrand]

You guys are cracking me up.
So how WIDE is the shop going to be???

Kevin, I don't know how wide he's going to make but I do know how long he's gonna need it: He's gonna need it for a long time as he is planning on making lots of guitars in it, bah-hah-ha, bah-hah-hah-ha! I'm sorry guys but I just couldn't resist, you'll have to excuse me, I think I'm running a fever!

12 feet wide, but I will take 2 feet for cabinets and shelves.
Perfectly intonated.

you intonate the work bench and hold the cabinets 2 cents flat . The action height off the floor should be belly button height for best results

The workshop is moving along. The digging is complete and I have pan decking in place. The concrete floor should be pored next week. After that The room can be framed. I plan to have a small vented spray booth with only filtered air. I am looking forward to that as the dust is driving me crazy as I am trying to finish the two guitar I have in progress.

Dang! You are a brave man, and I mean that. I think you are creating a shop out of space that others would not ever think to use. I await the next step.

After the walls are in and a lot of lights, no one will be able to tell that it is really an underground bunker. I can use the room as a bomb shellter if times get tough. I still have a 2 foot crawl sapce under the new floor and I have a french drain around the room. Under the pan decking is 2 inches of rigid foam insulation. The floor is going to be 6 inches of concrete with two cross layers of 3/4 inch plywood. The exterior walls of shop will be built with exterior grade insulation.

I will not have windows, so good light is going to be key. I am planning to use good quality floresent tubes for the base lighting to avoid shadows. I will have good spot lighting as well in key areas. Lighting is a main concern.

The other concern I have is to make sure that the vibrations of the tools are not coupled to the rest of the house. It would be a drag to have the shop but still not be able to use it during the crazy early hours of the morning. I wake up at 5 my wife wakes up between 9 and 10.

There are lots of acoustic treatments that can be applied depending on how crazy you want to get. Of course the ultimate one is the room-within-a-room. The floor is floated on vibration dampers of some sort. The wall studs are staggered so that every other one is inside the room by a little bit, say, a half inch. those ones do not attach to the exterior plate, but to the floated floor. Likewise, the ceiling attaches only to the inner studs. In this way, the sheetrock does not transmit vibrations to the exterior walls. Pressboard made from coconut fibers is often used beneath the sheetrock for additional damping. I've also heard of using two layers of sheetrock, which are usually staggered so that it's a pretty tight envelope. You can play the drums in such a room and not hear it on the outside.

I have been working with the builder to get good isolation for sound. I sort of have a room under the house, but I did need to tie it to the foundation of the house so I do not have as much isolation as I could have. I am not worried about music or even drums. The floor above on the first floor is 6 inch of concrete. I will have a ceiling in my shop that will further isolate the sound from coming from the shop. My only concern is coupling the vibration from the tools through the concrete floors and foundations.

I just had the floor pored today. Starting next weeks the walls will go up.

[ColestineGuitar]

Wow, with that much massive concrete you should be okay for sound. Heck, a simple padded workbench (or maybe some sort of rubber feet under the workbench) would decrease vibration even further if you find it needed. This is an exciting project; Getting a nice work space is life changing!
