I haven't been able to get anything done because of the rain over here in georgia, but I do have panels 1 and 2
assembled. Panel 3 or all the panels with 45* degree edges is where I am at a stall. It is not easy trying to cut
these type angles across a 4" wide panel with a circular saw, so I am using the time to think of some kind of jig
to construct to make this possible. I'll have something soon. Meanwhile I am sanding the inner rings of the baffle
and spacer so the part can clear the subwoofer sides.

Try clamping a larger piece "behind" the 4 inch piece, so that it supports it and prevents the 4 inch piece from turning/twisting. The larger piece can be fully clamped to the sled, but the edge tucked just inside the cutting edge.
Make sense?

Thanks Tom . I'll give that a try. I was actually thinking of something like that. I am needing to make the cut without the saw housing or clamps
getting in the way.

Here is what I came up with to help me cut angles on smaller panels without things getting in
the way. If I needed to cut panel a bit larger I would just unscrew the fence, re-measure and
screw it back down into the new location. It is re-usable. I call it my jig-a-ma-thing for angle cuts.
Here is a closer look at the results. Had to do a little trimming here, but it turned out good none-the-less.
This is the access panel I re-cut. The edges are a lot straighter and the gap between this panel and the side is tiny.
I still have to get some more sanding in on the inside edges of the side panel to kind of make them look neater.
Just a different shot without the access panel in place.
This is what I just completed a little while ago. I only have like 2 1/2 hours to work on the build after I come from work before it
gets too dark to see what I'm doing.
I also worked on the baffle, sanding the inner rings so it clears the subwoofer when placed on top of it.
I wish I can put these together as fast as you guys. I so badly want to here this. Been stocking up on budget Blu-ray deals from
Walmart so when that day of completion comes I will be ready to break it in for real.

Give the driver it's break-in in free air...such as hanging from a hook. It will be quiet, rather than really loud when mounted in the cab. IITP.

Thanks Tom. That is what I plan on doing.I meant I can't wait until after everything is finished so that I can break them in
some more in my home theater.

You're doing great. Keep going!

I could never make angle cuts that look as good as yours with a circular saw. Kudos to you.
And I certainly understand not having enough time during the week to work on your projects. I get up at 4:30AM and get home about 5:00PM. I have an hour commute each way, so I'm shot when I get home. Then there's family to deal with and you gotta EAT dinner...then it's bedtime. There is NEVER any time during the week.

Man look at the ass on that babe, ooops I mean magnet!
I had a small gap near the bottom left of this panel so I used a piece of scrap to kind of patch it in.
Just another angle of what I have completed so far. I also managed to cut all the 45* angles on all the panels that needed them
using the jig I constructed the other day.

Is it okay to coat the cavity that the woofer will be installed in with black underbed coating? I have a can still un-used from
when I built my mixer rack. Just thought It could be put to some use.

I'll betcha he's thinking "sound deadening/anti-resonance coating." That would be an unnecessary and time/material wasting step, kenkenni. The only rule for the woofer chamber is 100% absolutely air-tight. Doesn't matter what it looks like or if there's any coating/damping material on the walls. It's not needed and doesn't "give you" any return on investment. If you're at all worried about the chamber being air-tight, after the PL has dried for a couple of days, put a fillet of clear silicone over every panel joint and fillet it in with a gloved finger. Just the let silicone dry for 48 hours before installing the woofer/sealing the access cover.

Thanks for the response. Miked that is exactly what I was thinking and also being that I am going to paint that
area black anyway then why not finish up the can. It dries on and looks like Duratex though not as thick. I used
it on my homemade mixer rack. No biggie though, thanks for the advice.
