Re: 2016 Porsche Macan S - stealth SQ build
Agree, totally have to work from the edge back to the final position. Can't plow a ditch then cut the fin at the edge, that's asking for tear out.
Your way is marginally more stable, but my way is marginally more accurate.
Although, as I think about it, accuracy is not really needed here. Still, either way. I think it's good practice :)
Geo, I forgot to mention in PM. I told you via PM you need a deeper rabbet to compensate for the carpet thickness. If the bare rabbetted wood is flush with the floor with installed, then it will be 1/8" too high when the top is carpeted. If you wrap the carpet around, then it's another 1/8" proud.
I just remembered for your rabbet width (you said 0.75" and 1.00"), you need to widen that too to compensate for carpet if you upholster the backside (and you should!), or else it'll be a super-tight fit.

That's why I am waiting for the carpet to arrive.

Re: 2016 Porsche Macan S - stealth SQ build
Just curious why the use of a "Rabbit" bit for these kind of cuts vs a Dado blade?

Dado blade would work if you have one, and don't mind making multiple passes to clear all the material. I feel like the depth setting is a little less precise than a router, though I'd dial it in with scrap wood in either case. Would totally work - that first cut to remove the edge material might be a little tricky, but if it left a hair of material that's easy to remove with a knife.
I personally don't even own one in part because I do have a router and different sizes of straight-cut bits. I see it as just another tool for wider groove-type cuts, which is also what a dado is really for.
Dado blade is also more expensive than a straight-cut router bit. Just never saw the value.
It's always interesting to see the different ways you can achieve exactly the same result, though.

Re: 2016 Porsche Macan S - stealth SQ build
So it was a scorching hot 4th of July today in Southeast Michigan. What a great day to build more speaker rings for an impulse buy:
Attachment 12294
Anyway. I got a few more toys in to help me with this job:
After being held in limbo by FedEX for 4 weeks my router shield finally came in. Wish I had this 3 weeks ago when I was making 100 dangerous cuts on the router table.
Attachment 12295
And here is a down cut spiral flush trim bit. Supposed to make the cutting process cleaner. Mmm. Maybe not so much. Nice bit nonetheless.
Attachment 12296
Start by getting out the templates, marking on HDPE, and then rough cutting. What a mess in hot / humid / sweaty weather:

Re: 2016 Porsche Macan S - stealth SQ build
Rough cutting done. Let's get to routing the new style:
Rough cut rings.
Attachment 12304
Apply double sided tape on both sides of template. One layer to hold template to rough cut work piece. The other to hold template to router shield.
Attachment 12305
Attachment 12306
Attachment 12309
Cutting was perfect and safe:
Attachment 12307
Attachment 12308
Created a lot of scraps that I may find useful:
Attachment 12310
Drill pilot holes and add smooth chamfers.
Attachment 12312
Attachment 12311
Attachment 12313
Done for the day. Time to start grilling hamburgers, brats, and hotdogs....

Re: 2016 Porsche Macan S - stealth SQ build
I forgot to mention that the new speakers cut out diameter was 1/4" larger than the hole size of my templates I made for the AP8 midranges. So, I had to improvise a little with my rabbeting bit set up to cut an 1/8th" rabbet.
Attachment 12316
The bit didn't quite make a full 1/2" cut. It left a sliver at the top. But, this was easy to clean up with a chamfer bit as you can see in my last post.
Attachment 12314
Attachment 12315
Oh, and for the spiral cut down flush trim bit. SOME of the shavings ended up shooting into the router table. Most still shot outwards to make a mess.

Re: 2016 Porsche Macan S - stealth SQ build
Where did you order the router shield from?
I'll bet that makes a huge difference in the comfort and security when working with smaller parts...

The router shield is from mobile solutions. It cost around $60 but worth every penny. Gives you great control and security when working with smaller plastic pieces on the router. Mark on the Car Audio Fabrication Youtube channel recommended it.

I'm showing my age - but SPL (and fabrication) legend Mark Fukuda used to sell a router shield - was his invention and innovation.
As a matter of fact, when Bryan Schmitt was here in Buffalo training my fabrication team, I swear it was Fukuda's router shields he supplied us with.
It was either him, or Billy Brown (who actually built our shop, and is tight with Bryan, since he used his motorized router bases for our two router stations - I wish I still had access to those) who told me about Fukuda inventing it.
