Hey..
I'm getting close to building my box (parts are already under construction).. but I have 2 questions..
First, where can I get those round speaker moutns? or are they made ( I have some scrap I can use, not MDF though, subfloor material 3/4"..)
Second and more importantly.. I was looking over some fiberglass supply companies stuff and see that there are a LOT of different options for glass and they all have differing costs.. I could run from Kevlar and ~$350 for my box to Carbon Fiber for ~$700 for the box to various types of 'mat' and 'fabric'.. So, the question is...
How many layers of what kind/size/weight mat/fabric would I need? mat is a lot cheaper than fabric but would require more layers I think.. Then, there is carbon fiber 'cord' or stranded stuff (not that expensive when you think about it) that can be used like one would use rope I'd immagine, but the carbon fibers should be a lot stronger.. so, if I used a fabric outershell for smoothness, then put some fiber strands in (not too thick like a rope, but kind of like a thin meshish thing) and mat, fibers, mat, etc.. About how many layers would one need if they put in a little carbon fiber stranding between layers? What weight mat and how many layers if just that?
And, also.. most supplies are listed as sold in x yrds.. yards I'm presuming.. is there a standard(ish) number of yards needed per cubic foot? I know shape has some bearing on surface area over volume.. but there has to be something that gives me an idication.. would I need 5 yards for a 1 ft^3 box? 10, 15, 20 yrds? This all has a bearing on what material I get (obviously).. Is there a general rule of layers/thickness for different mats/fabrics that would make a difference? For example, I could run 3 or 4 layers of 6K heavy mesh Carbon Fiber and I think that would be thick enough, but that would cost ~$450.. a bit more than I'm looking to spend on a glass box.. the cheapest mat (guessing 8 layers, and 24 yards total) is something like ~$40, but that's only just over 1/8 inch (or so it seems) and that seems thin.. unless 4 oz mat (4 oz / ft^2) is that much stronger than ckeapo stuff from WalMart, for example..
The big reason I'm asking is, I can't just run to the store if 8 layers isn't enough (since I'll be ordering it online), and I'd hate to buy enough for 8 layers (with carbon fiber strands intermixed) if I only need 4 layers if there are fibers..
*sigh* Hate to ask another fiberglass question, but none of the tutorials I've looked over really specify anthing specific on what type of glass, weight etc..
Any info would be helpful,
Thanks..
