Planning to build a box...what materials?

[Frankensuby 10+ year member]

Ok, well I bought all the stuff needed, and made the preliminary cuts. People helping me out with the internal volume figures have been as low as .64 internal and as high as 1.1 internal volume, so I'm gonna guess it will be about .75-.8 internal volume without the driver.

I know I need to recut one piece because I was in a rush to get the cuts done before work, but so far it looks promising, albeit a little small.

Is it true that polyfill will make the sub think it has more volume?

If so, I might grab a bag of that in case my internal volume is a bit smaller than I wished.

I'll try to get pics up in a day or two, depending on progress.

Another rather random question: Is the 3/4" MDF at Home Depot vinyl laminated? The Sealant I got says not to use it one vinyl laminated MDF.

Thanks,

I havent bought MDF in years, so I dont know the price of that ($15-20?), but I pay around $28 per sheet for Trupan.

How would Trupan compare to Birch?

Birch is about .1 pounds per square foot lighter, but runs around $.25 more per square foot.

Alright guys, always use a table saw for straight cuts //content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif

I have the box mostly together, and the first round of adhesive is drying now. As I posted earlier, I had to use a jigsaw for lack of better equipment. Next time I do this, I'm definitely going to use a table saw of some sort. My edges were bad, although I planed most to sit flush, there was 2 spots that I could do nothing about because if I planed them flat, it would throw the rest of the edges off.

I ended up using alot of construction adhesive to fill in these spots. I threw a bead in the middle, threw it together, and then threw and layed a wide bead on the inside and outside of the problem areas. I've worked with this glue before, and it is meant to keep medium sized boulders and rocks in place in Landscaping, but is excellent for high pressure wood situations. I hve applied this glue to each pilot hole I put in, and to each surface screwed together. My concern is that one area probably has a span of 2/16" that I had to fill in. Do you think I should be ok after its' finally cured in 7 days?

I've ripped MDF apart with this glue holding together, but that was on flush edges. I'm also going to be using aquarium silicone to add to the internal seal before I finish fiberglassing. Will this balance out my mistakes?

By the way, I think the box looks ok for a first time builder //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Pics by the end of the night //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
