Building a Box

Well, I kinda have an idea. How bout taking like a ball or something, like one of them bouncy ball from K-Mart or somethin, and fiberglassing over it

Yep, thats what i had in mind. Or a similar process as to what they do when making easter eggs, in two spherical halves then joining them.

Well, great minds think alike I guess. haha

Heres how to calculate it............ aaaaahhhhhh the power of the web!!

The volume V for any sphere with radius r is equal to four-thirds times the product of PI and the cube of the radius. The area A of any sphere with radius r is equal to 4(PI) times the square of the radius.

Volume Formula: V = (4/3)(PI)r3

Area Formula: A = 4(PI)r2

Wow, thats exactly what I was gonna say... yeah, exactly

yeah right.......:D ......:flipa:

Also, how are you gonna secure it in the trunk?

thats easy, luggage ties:D anyway, who said i was gonna secure it to the trunk?? i might aswell suspend it from the roof lining!!

hell yeah, with some LED's on it!

I could have hundreds of LED's on it, all different colours, i could have i spinning too, like one of them 'Disco Balls'.....haha:D haha:D

i checked today and i can get 3/4 inch MDF. :D only for $20 USD too :eek:

Yay my subs came in today :D :devil: :o :eek: finally. so P11GT, what specs do you need, you needed the sub displacement right? is that the dimensions of it? or something else, im reading it and it doesnt say "sub displacement" but ill post down everything it says.

thats all they gave me. hope its what you need. now, back to the box :D

ok, give me a few days and i'll sort it out for you.

Right, heres the start of your box. Now go buy your 8ft x 4ft MDF board and mark and cut as follows. Theres gonna be a lot of waste, but you can always keep it for something else later. Make sure you get 18mm thick MDF.

heres what you do with the bottom section you cut out. This is for the side panel......

Let me know when you get thus far, then i'll take you thru the rest. Keep in mind that the diagram below shows you how your box will fit together.

is Strong Spray Glue and Contact Adhesive the same thing? what does Silicone Sealer look like? is it that actual sticky silicone? i put that on all edges on the inside? ill start getting all the materials, but ill be gone in a couple of days to go to France for like 3 weeks, im going to try to get a little done before i go, but thanks for the designs :D oh ya, how high/low grit of sandpaper should i use?

Yeah, spray glue and contact adhesive are the same thing, i just use it from a spray can cos its easier to apply. Silicone sealer is what you'd use around windows, or your bath tub, just get either clear or white sealer, it doesnt matter cos it wont be seen. If you can, use a hand saw to cut the wood, a jigsaw sometimes will not cut too straight, but best to get someone with a cutting bench to do it, cos you need a perfect 90 degree angle on the edges, aswell as the edges being straight and true. This is because youre using a 'butt joint'

cool i just got my 4X8 MDF today, i had the hardware store cut it for me. they did all the 90 degree cuts, i just have to do the side pieces and the partition. i just got a hand plainer. just as good. im going to start working tommorrow. i bought 1.5 inch self taping screws, the head is about 1/2 inch though. you think that will be ok? its just the head, the rest of the screw is small. how long did it take you to finish yours? on side D, when you said screw the screws in at an angle, do you mean going up (sides E, F, and G)? or do you mean across screwing the screws on an angle to side C? if i did go across screwing the screws angled from side D to C, the screws would show a little. just need to clear that up. :D

hey guys, i started building it today, here click to go to my website (http://nituning.cjb.net/) and click on "Current Project(s)" to see some pics and my progress. :D

aaaaaarrrrrrrgggghhhhh!! Dont jump the gun!! theres a fews things you need to be aware of before you put it together.

sign onto MSN Messenger, im online now

what steps am i missing?

The main thing is, that the side panels are recessed in from the edge by a quarter of an inch, this has been taken into consideration when i designed it. This recess servers a purpose when it comes to finishing off the box, and allows carpet to be covered seamlessly. Ive got some pics and need to give you a discription, so i'll try catch you on Messenger tonite, just sign in, and wait for me there.

what do you recessed? do you mean it sticks over the edge? dont worry i only glued the bottom and back panel together so far. i shaved the side panels so they would fit flush on the bottom and side, but there is a small tiny gap still. ok cool ill meet you tonight. if you dont see me on, just post pics. thanks :D

First of, you dont glue the sides, you need to drill and screw them or its not gonna stay in place. Recessing the sides is as follow..........

if you look at the picture below, the panel going from center to right of pic is one of the side panels, the panel its attached to is either A, B, or C. Notice how its not met right at the edge but is sitting back quarter of an inch. This is the recess youre gonna need to do.

c'mon c'mon, whats the hold up?? it should be done by now:D

dude, they your sandles??? hope you dont go drive your G in them, man you got BIG feet! :D

They don't look that big to me

aw man, cant finish my box for another 3 weeks. ill be in france for my winter holiday. if you want to see pics of my box and progress so far, click the link in my sig. i only have to cut out the two circles where the subs will sit, and carpet it. anyways, talk to you guys in 3 weeks :D

Well after returning home from Europe, Aznvirus has finally finished his Box........... and here it is...........

I think you'll agree that is a piece of art, considering this is his first DIY box, hes done extremely well, i could even pass as being bought. To see his project in full, click the link under his sig, and click current projects.

Weldone there Deric!! You da man!!!

If you wanna make your own box like he has, give me a shout, i'll be glad to help.

thanks for the gracious words Kevin :D now i just need my own car! :p if anyone would like to make their own box, go to Kevin, he knows what hes doing. its only for a small fee (check the thread "Offering My Services: Custom Designed Sub Box"), but trust me, its better than paying $200-300 for a custom box.
