Hmmm...OK...I'll go over there today and take a look...didn't see anything on their website. Also thinking about Acoustic Foam...its probably quite a bit more expensive though:

Got the soundboard from Lowes. It comes as 4x8 sheets and is pretty cheap.Originally Posted by piperpilot

Try ceiling tiles, though not the expanded foam type. They are designed to absorb sound. They are quite inexpensive too.
According to the Lowes web site, "soundboard" is no longer available. Here's a link: Shop 1/2" x 4' x 8' R1.2 Sound Board Acoustic Insulation at Lowes.com
but this stuff ("SoundChoice") looks like it is about the same: Shop Dow 1/2" x 8' x 4' Insulated Sheathing at Lowes.com=
If I remember correctly, the soundboard was about $10 for a 4x8 ft panel.
Was at Lowes today (Ventura, CA) and found they are selling soundboard just like I used. ($11.30 for a 4x8 ft sheet)
You can get foam "signboard" from most newsagents, it's basically 5mm thick foam with a hard white plastic skin on each side. If you glue that inside the wood cabinet it will take a heap off the high freq sound.
It's cheap, and you can cut with a box knife and glue it in place. And being shiny white plastic it's good for light reflection and easy to clean.
Thanks guys. Was at the Depot today and they didn't have any soundboard but they did have acoustic ceiling tiles. They were $0.54 a square foot..sold in 2'x2' and 2'x4'. I will check Lowes tomorrow for the soundboard, or also look at the signboard option. I'm using 3/4" MDF, so it already should be pretty quiet, but I figure any extra is worth the few extra dollars.
So I'm making some progress in the construction. I had originally thought to do some inset MDF panels like Don did, but seeing I don't have a router table, routing the dados out of the 2x4 turned out to be a problem. So I'm sticking with just a basic frame where I will hang the MDF panels on.
To avoid problems with racking, I have probably over built this...but better safe than sorry. First off, I used 3/8" dowels to connect the 2x4s together. This provided me a VERY square frame and it is really stable. I glued all dowes and the 2x4s together. Then clamped. Here is a picture of the dowel setup and the clamping. In addition to dowels and glue, I used pocket screws to hold them together. This was made much easier after I screwed up a first couple sets...I bought a jig for drilling the holes. Sorry for the bad pictures with the cell phone in a not so great lit garage.
I also found some galvanized building supports that I am gonna use to provide a little extra stability.
Using these for the top side:
And these on the bottom:
The base is put together with top and bottom on and these sides will mount on top of it. Hopefully I'll get the top frame done tomorrow and can start skinning the top (roof), sides of the base and building the removable panels for the enclosure as well as the door for the front. Door construction will be a little more difficult...any tips on how to accomplish this would be greatly appreciated.
I'll post some more pics in the next couple days as it comes together better.

I see you're going to use removable panels. I found it very helpful to index my removable panels vertically so that they could be easily removed and reinstalled. There's a whole bunch of ways to do the indexing but I chose to use a 2x4 mounted horizontally near the top of each removable panel.
Yes, very similar to your setup Don...I want to be able to take the sides off to work on the machine unimpeded.
For indexing, I was thinking a couple of T nuts drilled into the side of the base where I can screw some bolts or threaded rod as supports to hold the panel while I line up the mounting holes. I can't really use the 2x4 method like you did because I don't have that "upper shelf" that is formed by the inset panels.
Here's some photos of my door. They may give you some ideas. I did use dados cut with my table saw to enclose the mdf. I used 3 large hinges. The acrylic window was captured in the dado with pieces of hardwood. I used a clasp to close the case. The 2x4 underneath the clasp protects it (and me) from trauma and also serves as a handle to move the case around.
The mdf panels are heavy. If you can work out some way to hang them on your case in proper vertical alignment, it will make it a lot easier to install the screws. (Imagine holding a 20-30 pound piece of mdf in one hand and a screwdriver in the other balancing a screw.)
I tried to cut dados on my little portable table saw, but I think my blade was too dull. I had used it to lay a laminate floor years ago. I might get a new blade and try again.
Do you just rip down the edge multiple times to get the dado? Definately learning some new carpentry skills here! ;-)
Thanks for all the help Don...I can only hope my finished enclosure looks and works half as good as yours!!!
