It actually handles the 2nd row 1st reflection points, I'm holding off making the 1st row 1st reflection points Acoustic "Cloud" until I'm done with Bass traps in the corners and do some detailed room readings.
-(1) 1" x 10" x 12' pine board (ripped into (2) 4" wide boards)
-(1) 1" x 6" x 10' pine board (for the ends and the mid sections)
-Fabric, 56" wide, cut 13' 2" (I got 20 yard roll for all my wall treatments except the side wall ones, which used black speaker cloth)
-drywall screws, 1 5/8 for the end/mid section pieces, 1" for the T and L braces
-T and L braces
- #6 J hooks
-electric stapler and staples (I used 5/16 for this project)
I built a 2' x 12' x 4" deep box as shown:
Note: I separated each 2' x 4' sheet "zone" with a 1" x 4" x 23 13/16 support, reason 3/16 shy of 24" is I wanted to "grab" the 2' x 4' sheet lengthwise by tightening the screws, it worked and held the fiberboard nicely.
I used a 24" clamp to squeeze the 2 outside boards together as I did the final tighten.
Has anyone tried to find 1" x 6" x 12' straight lumber lately?
I actually had better luck buying 1" x 10" x 12', dead straight, and then ripping it exactly 4" thick to hold the (2) stacked OC703 sheets.
Got (2) 4" wide 12' long pieces that way, dead straight.
Important to look at the endgrain of boards you buy also, you want boards from the outer rings of the tree, they are more stable.
Having used the simulation software for the 1st reflection points, transferred those locations via blue tape onto the ceiling.
Confirmed their accuracy with 1' x 4' mirror and my wife....she was on ladder holding the mirror flat to the ceiling while I was the one sitting in the chair analyzing
Then, with the build wood box, get exact mtg locations via blue tape and much measurement/cross checking. I'm hanging these into the ceiling joists also.
btw, My favorite tool for long straight lines is still this "Strait-Line 64001 Laser Level", $39 @ Home Depot 6 years ago, it has little pins that hold it even upside down.
I found a simple bread knife worked perfectly fine to cut the OC703
Buy lots of hardware, then decide exact method OJT (on the job)....this is after all my 1st time doing this.
I ended up going with #6 J hooks for both the panel and ceiling, and black chain. Will return most of the stuff you see here.
(and those ATS Acoustic plastic screw in anchors I posted above, they are ok for single panel but not for huge beast like this.)
Made this handy drill jig so I can have straight/inline screws.
The 5 minutes it takes to make these pays off with good results later.
Paint the silver hanging hooks black, use a box as spray booth
Add T and L supports to the box, and of course the fabric ordered and delivered (I got 20 yards of 56" wide forest green fabric).
Cut fabric and get ready to use that electric stapler!
Part II coming shortly....
