Well guys I decded to get my feet wet and start an A pillar build. I'll admit right now that this is the first time Ive ever tried to build anything like this. I'm sure I'll mess a bunch of stuff up, but that's how ya learn. I've already made a bunch of circle cutting mistakes but at least now I can make them :).

Here's what I've got so far. More pics to come.

Yay for Jasper jig


Circles cut and double side tape attached in order to cut into a ring



You can also use double sided carpet tape. It doesn't have a foam inside so the wood sits flush.


Rings done. I used 3/4 MDF






That's it for today.

Suggestion: notch out the back of the rings on the internal side of where the speaker goes. you want the back wave to have as much room as possible. only leave alot of wood at the screw holes if that makes sense.

lookin good :)

I saw that tip in your build log and I plan on it. Thanks! I also want to find some plastic like you did so I can wrap it around the edge of the ring in order to make a compression fit grill. I got alot of ideas from your thread :)
I like speakers in the pillar
let me know if I can help you in any way. :)
"Day 2"

Not a good start. Had a bad omen before I even started working. This is my fortune from my chinese dinner. Might be hard to read :surprised:


I say day 2 but it's really like night 2. I'm am working on this about an hour a night after work so this will be super slow build. I'll prolly make some good time this weekend tho. Anyways on to the pics.

Marked off no cut zones.


Chamfered the edges. After inspected I need to go over these again I guess. Never done it before so maybe someone can tell me if it looks ok or not.

I also went shopping tonight for build material


Fabric Remnents :)





Found this ruler type thng in the quilting section of a fabric store. I'll use it as an outer ring so that I can make a compresion fit speaker grill. Got this idea from BigRed's hybrid build log.

I've also got some resin somewhere. Not in the picture.
cool work! Methodic and timely...
Take your time, let those L3's breathe and they will reward you! So the rabeting you have done on the back of the baffle looks good. Stick an L3 in there and see how much of the back of the cone you can see. The more, the better :D

ps, avatar, it comes from the down?

here's a closer look at the rings with the L3's in it. I always like to get pics with flash and without. Never can have too many pics :)

Take that bondo crap back. Then look up Rage (Rage Gold, Rage, or Rage Extreme) online or nearby. This will save you HOURS of work.

I've used the bondo filler in the past and it did require tons of sanding. I'll have to see if i can find some of the rage products. Thanks for the heads up.

Thanks man!
I'll be interested to follow this as well. I've used the Bondo glass and regular bondo in the past. Is the Rage stuff that much better?
I called around for rage gold products and found a place that sales it but it's like $30/gallon.

I'm not in a race to finish this so I think I'll stick with the bondo filler and just do a bit more sanding. I will be covering the pillars with more fabric if I can find a close match to my headliner/pillar material so it doesn't need to be perfect a few pinholes shouldn't hurt.
Looks like you're off to a great start. Thanks for posting. Looking forward to seeing how this progresses.
Looking good! Definetely go with the Rage Gold, $30 its worth every penny when you see how easy it is to use.
