Mixing fiberglass and MDF... need help. (aka fiberglass box progress)
Alright I've been talking about it forever, but hopefully monday I'll start on my new box. I'm just gonna do a simple sealed enclosure. However it's with my 1KW eD 12a, so I want to make sure it doesn't 'splode...The larger MDF components I'm currently planning on are the bottom, face, and mounting plate (I'm borrowing the bolt it to the jack-holder idea) I figure with everyhting else,I'll mostly see what's looking potentially weak and try to re-enforce it from there (hopefully those seemingly wasted engineering courses'll come around)
Sothen what I need help with is joining the 2 materials together... let's start witht he bottom plate. This is going to be a large flat area, and thusly succeptible to flexing, so I'm pretty sure a sheet of 3/4" MDF cut to fit the floor of my car in the area would be the best idea for the bottom of my box. Would I be wise to put down a layer of fiberglass first, then wood, then fiberglass over it to sort of "encase" it in a cocoon, or would I be better to just have the wood in there to begin with, and sort of fiberglass up and over the edge? My thoughts at the moment are to laydown a layer or 3 on the bottom, then place the wood on top, then try to "sandwich" it into place with a couple more layer on top (atleast up and over the sides a good couple of inches), but this may be overly redundant.
I'm not really too concerned about the faceplate, (woofer mounting ring) eventhough I WILL have ALOT of magnet hanging off of the back of it. I'm pretty sure the resin-soaked fleece will saturate into the wood well enough to get a good bond. But my mounting plate kind of concerns me... Basically I want to mount my wire terminals in a chunk of wood that will also have a mounting hole to bolt into the jack-holder. THis way the loads of the box trying to shift will be spread throught he wood instead of jsut to a small hole drilled in fiberglass. So far my thought is to make the plate, Mount my terminal plat eon it, then tape off my area, and bolt it to the wall, then Fiberglass over it, I guess?
Prettymuch I'm mostly concerned about how well fiberglass will bond to wood. Should I even be worried about this?
Edit: this has kind of turned into a bit of a fiberglassing aid, so I thought I'd list my resources upfront Thanks VERYmuch to these guys who I don't even know, but who's wisdom has helped me along, as it may withyou.
