...break this out from the master thread...
Well... after making my first purchase towards this project 6 months ago
I finally had the time (where the wife and kids were gone) to make my first "superchunk" style, corner, bass trap.
For the larger trap I used
3 - pieces of a JM equivalent to OC703, 2" thick.
1 - FRK panel.
3 - 48"x1" dowels (from HD)
1 - 2'x2' 1/4" hardboard panel (from HD)
6 - screws
about 2 yards of speaker cloth from Joanns Fabrics
You can check out the superchunk info here
. I used the 24" pattern on the 3 pieces of fiberglass, and also added the full panel of FRK in front of that. To cut the triangles I used a straight-edge to score the panel with a utility knife, first lightly, then a little deeper. This created an internal channel for the $10 electric carving knife that I used to make the final cut. By the way, this method of scoring then cutting works really well. The internal channel guides the carving knife to the point where you could literally make the cut with little concentration.Check out the short video of me doing my cuts, here.
Please note I could not find my mask, so that is part of an old t-shirt
covering my face. Also, since I filmed this myself, my technique is not perfect. Really I just wanted to show how easy this stuff is to work with so you people on the fence can just go do it.
The frame is made from the hardboard panes cut a little shorter than in half, diagonally. I used a hand saw because I don't own many power tools. The triangle was estimated using a dry-fit of the 1" dowel, the triangular fiberglass, and the 2" of the FRK.
The bolt of speaker cloth at Joanns was wide enough to use a straight peice of fabric.
I'll try to measure the FR at a later date. I want to make a few more panel first.
...just excited to share...
