Mounting Ring

Hey. I've seen Chris's tutorials and read a bunch of posts talking about mounting rings using dowel. My friend and I made a custom speaker box for his civic that held 3 pairs of speakers. We used Dowels to mount those rings, but it was such a pain in the a$$. One of us had to hold the rings, while the other glued the dowel down. Plus, getting it symetrical on both sides was a pain using dowels too. I've seen pics of boxes being made using not a hollow ring, but one that looked almost like a pizza.  With some kind of wood holding it in the center. I guess the ring would be cut out after glassing it, but what do you cut it out with, a router, or jigsaw? I figured a jigsaw may vibrate it way too much and wouldn't be the best for the fiberglass. Anybody have any tips or links on how to do this properly. I also think this would be an easier way to get the symetry I want on my next project. Any advice will help. Thanx.

The wood holding it in the center is a 2x4 or a couple of MDF pieces sandwiched together, depending on what you have when you need it. You can cut out the opening with whatever works for you. I use either a router/circle jig for flat rings or an air body saw for flush mount rings (too close for a jig saw or router).

Whats an air body saw? I dont think I cant get a hold of one of those. Is there anythijng else? Or any other ways to pount the ring without using dowel? Ya, I'm goin to a flush mount.

This is an air body saw.  If you ever cut plastic or fiberglass, you will always be using this.  It gets into crevices and corners and cuts just about anything.

$20 Air saw I wonder what how long that tool would last?

How about a recipricating saw? I buddy has one.

As far as symetery I used tomato vine fence/rings.  If I can get these friggin pics loaded I'll be glad to show you how I did it.  I mounted two subs and they came out really close for minimal time of cutting and sanding dowels.  And it holds good.  I'll try and get some pics up.

Hey boxmaker have you tried to upload them to this website by clicking on the tree with the arrow pointing up.  And make sure the .jpg is at the end of the file name.  Thats why mine wouldnt show up.

Yep, that's an air body saw. I suppose a recip saw would work but that's a little big and awkward for a job of this size.

Hey thats a good idea I never thought of that.   Or you could do what placid said and then tape up that area so that no resin gets on it, once done remove tape.  Then you could take like a hacksaw blade or any kind of blade you can hold in your hand and cut through the little attachment points that placid was talking about.

I do something similar. I pre-cut the opening with a router and circle jig about half the depth of the ring. Then there is less material to cut with the air saw.

If you cut all of the way through be sure to tape off the holes so you don't get dust inside the enclosure when you're sanding.

Ya I was thinking I might just dril a ridiculous amount of holes around the entire ring...then take a smaller saw and cut it out.  Whats the problem of getting dust inside?

Yeah really I got dust all up in mine the whole time I was building the thing.  So what is the problem with the dust?

The dust gets into the gap between the voice coil and the former. Not good for your speakers.

Well how do you make sure you get it all out, so far ive just been vaccuming it out.

Thanx for that tip. Guess you learn something new everyday eh? I'll make sure to clean it out good...By the way, does anyone have any pics of projects they've done. I've seen tonnes already, but you can never get enough. It's like porn, tits are all the same..but we still love to see a new set.

I think wiping down with a wet cloth would work pretty well. But vacuuming to get large amounts would work.

Yeah thats what I thought about was doing using a wet rag or something. Shouldnt be too hard.
