After seeing MTT's build in the General Discussion section I felt inspired to do something with the Solid Surface (Corian, Staron) leftovers I have. Basically acting off what he's done he is what I came up with. It houses a 6 1/2" speaker. Threaded sleeves for ease of install and un/reinstall, won't deteriorate like mdf.
Sorry for the low quality pics, they're off my blackberry.

 

Looks good!

 

yeah, and nice clamp collection you have going there.

 

Thanks. I've got lots of tools in shop that would probably give most car audio fabricators wet dreams at night.

 

Looks like good work.

You used metal t-nuts which is fine, but if you have a tap set you could just drill and tap. It would be just as if not more reliable.

If you plan on fiberglassing, I would suggest rabbiting a section from the outside of the ring. This will give you a place to put your cloth with out causing any buldges.

 

Does this also include Metal rings? I was thinking of drilling 1/8" holes into the side of the rings about 1/4" deep for the resine to soak into. Spaced out every 1/2".

Using a drill press should make life easier.

 

I'm not a big fan of drilling and tapping Corian and related materials. It's to easy for things to break when tightening. Even in the fabrication guides/courses it stresses not to use a jigsaw or drill to insert a screw. The reason being the cut is not even and clean, this leaving any one of those areas to spider off and crack, the same applies to tapping the material. So the T-nuts just require a hole and the epoxy holds it in place, not putting any stress directly on the material.

Fozz, not sure I follow on where you're talking about rabbiting a section. One of the downsides of using this material is you can's staple into it.

 

No need to staple.

Are you planning on glassing?

 

Yes. That's what I figured

 

there are a number of blind fasteners out there, I am not familiar enough with corian to recommend any (crimp (rivnut), epoxy, friction (like the t-nuts you are using))
