Alright, last question for real here.
On the panels that won't be stradling corners, just pressed up against the wall (AKA behind me and to the left/right of my mixing position), would it make a difference if I used 2" or 4" thick panels? Trying to save as much cash as possible here
.
No idea, really. That shit is cheap as hell though!?!
Here are a bunch of pics from the building process:
1. Shawn is predrilling holes for the metal angles into the long boards (sides)
2. Then we drilled metal angles into the short boards (top/bottom)
3. Sideboards get screwed to the short boards
4. First frame done (a bit crooked), presented by lovely stapleing assistant Lynne
5. Frame gets placed on fabric
6. Lynne putting rockwool in there. We put 2 panels (approx 4 inch) in each small absorber and 3 (approx 6 inch) into the big ones
7. We cut up regular large garbage bags and used them to seal the back. Really cheap and easy. Just staple them to the frame.
8. After stapleing the fabric to the back, this is what it looks like:
The good thing about using plastic bags for the back is that you can punch holes in it and push hangers through, so that you can hang the absorbers easily ...
Some advice:
a) working with 3 people was perfect cause Shawn and I drilled and put the frames together while Lynne did the rockwool and plasticbag/fabric stapleing.
b) I recommend doing the stapleing on a large table because on the floor it is hell on your knees. I was glad Lynne is small and doesnt have knee problems like me, so she had no problems doing it.
c) if I'd do it again, I would probably use some sort of wire in the front to prevent the rockwool from pushing out a little. We did that for the large absorbers, but the small ones were already done.
d) try to be really precise with the fabric, because it will look crappy (like some of mine) when you do a half-assed job.
Hope this helps!
