OK, well, had a "fun" week at work. I basically had to interview with HR for my own job. I don't even want to get into that...I'm just glad that I have a job.
I finished up my sub, and it's setup in the home theater. I can hit 102db at 10Hz with 1500 watts! Watching Star Trek on Blu-Ray was fun! Though I need to EQ it a bit...but that's a whole nother project.
Now that I'm done with that for the time being, I cleaned up the garage shop and collected the pieces from the broken QRD-29. Just for fun, I took I what I had and made an 11 X 11 (actually, it's off by one, but it's just for practice). I just cut the fins around 11 X 11 since that's the largest I could go with what I had, and started assembling. I did go back to my slot jig and spaced like Terry and Paul were talking about. I used business cards to "add some slop" to the slots so they could be assembled without beating them with a 5lb hammer. There is a lot of slop in my 11 X 11 sample, but that's because I took all my practice and broken pieces and just slapped it together. The final product will be much more consistent.
Here is what I have so far:
I took the remnants and pieced together this 11 X 11 grid (actually, you can look at it like a 10X10 or 12 X 12 since I'm leaving the edges open). It's not bad for spare broken parts!
Bringing QRDude on the screen, I used my digital caliper to set the depth of the tiles.
Once I got the tiles set to the correct depth, I used a cheap paint brush and some wood glue to seal each tile in place. When I took these photos, I only had one row done...before I go to bed tonight, I'll have 3-4 rows. I'll probably finish this up over the next few days as it takes about 10-15 minutes per row. All the while, I'm thinking about ways to make this go faster. I still want to do a pair of prime 29 diffusers, but I may do some others using 2.5" tiles and a depth of 6" for my back wall. The advantage of going with a smaller prime is that I have fewer varying depths to deal with...though the adventurer in me wants to do something big and difficult.
I have no idea what I'm going to do with a single 11 X 11 2D diffuser, but it's a fun project and gives me time to think about and better plan the pair of Prime 29
