I'm learning that progress, for me, occurs in very small steps. I'm usually only able to do an hour or 2 (3 max) at a time on my cab, but now I can really start seeing the progress.
Today I got the speakers mounted and tested. Since I'm following the book closely, I ordered the Klipsch 2.1 system and the speaker grilles shown in the book. One of the images below shows the speakers mounted to the speaker shelf. Just like the book said, I had to countersink about 1/4" for the 1.5" screws to be able to grab. (I wasn't able to find 1.75" #6 screws like the book suggested.) This allowed the screws to grab and hold the speakers firmly. (And I've got to reverse the way I've mounted the speakers so the speaker cable is closer to the sides of the cab - in my haste, I missed that part.)
The good news is that the 8 screws I removed from the speakers were black and I was able to recycle them and use them to hold the grilles in place. No painting screws.
Finally, I hooked up the speakers and monitor to my laptop and tested the sound and video out. Everything looks awesome... and cranking the volume up to 8 gave me a Pac-Man experience I've never had before I can't wait to try out other games with these speakers.
1. I've going to mount the front panel using barrel bolts (4) on the inside. If I remove the control panel, I'll be able to unlatch them and remove the front panel if I like. With the Luminglas mounted on front, I don't want the front panel to be able to open on hinges like a door. Using the barrel bolts will keep it locked in place but accessible anytime.
2. Filling in holes - I've got maybe a dozen or so holes to fill in and sand down before priming and painting.
3. Prime, paint, t-molding...
