The wife has spent the whole week begging me for my old equipment (i'll say it again - she rules). So I did some shopping and got started on a little fabrication for my next install.

These pics are only of the MDF rings for the subs - the fiberglassing is next, but the weather is not going to cooperate this weekend, so this is all I have so far:


^ The beginning of ring #1. The MDF is 1.25" thick (3/4" and 1/2" glued together). That's my little laminate trimmer/router, and a homemade circle jig (piece of balsa wood screwed to the base, then screwed to the MDF).


^ After a few passes, the circle is done.


^ Next I milled a groove in the circle - this will become the mounting flange. Basically, the sub will mount to the 3/4" MDF, while the 1/2" is used as a trim ring to make things flush in the final enclosure (long ways away from that, but soon to be started).


^ This is the completed sub ring, with the outside edge "eased" with a round-over bit.


^ The sub inside the ring.


^ Here you can see how the flange method makes the sub nice and flush with the top surface of the ring - this will make for a nice-looking install once the fiberglass is all completed.

I'm just taking a break here - since I'm doing dual 10's, I've gotta get out and mill another ring. But things are going well so far!

thats a great idea on how you make the circles

Hey, thanks. You can buy pre-made circle jigs for routers, but the only "budget" one I could find is from Sears ($20), and I hear it's a piece of crap anyway. And my local Sears would have to order one for me - bah.

There are really nice ones you can find online, with literally hundreds of super-accurate measurements on them. If I did this work all the time, I'd buy one - though they run up to about $50. But for this small project, a $1.25 piece of balsa did the trick.

BTW - second ring is done. It went a little faster - chalk that up to experience with the first one. I'm filled with MDF dust, and I have brown snot when I blow my nose - dust masks are for pussies! .

I'm hoping to start 'glassing by next weekend at the latest. ******* weather guy predicted rain for today, that's why I didn't start - but even in the pics above you can see how damn sunny it was. At least it's clouding up now - makes me feel a little better. .

Hey there Hihoslva- great to see the start of your newest project!
Tools- just gotta love them. I have tons of them that I might have used only three or four times, but when you need them, nothing but nothing else will do!
I share the same types of weather based fustrations- On Thursday it was almost 80, today a high of the lower fourties. Hard freeze scheduled for tonight, but anticipated 90 (!) degrees by mid week. The locals call this yo-yo weather...
I am waiting to start my project in the mazdaspeed until I can get the RX-7 started up, tuned up, and blessed by my local mazda dealer.
My first step will be to strip the drivers compartment totally and start on selective sound deadening.
But as always (it would seem to me at least!) you have the jump on me for our respective new projects.
Great to see the photos, and please do keep us up to date on your progress, and please post LOTS of your good pictures..
Dave
