weve all been using mdf for a long time...

but has anyone actaully just tried to copy a box that works with just some normal 3/4 ply wood? ive been building with mdf and birch so long that i couldnt tell ya if there is a difference or not. most boxes get doubly layer or resin inside anyway, so in this case i wonder how just some plywood would work out.
i thought about this cause i was using some new stuff called arrcura ply or somthingthing like that. its a slightly cheaper alternative to the nice marine birch. seems to be pretty nice.

yes swat (timmay) has been for about 2 years now or fiber bord

so did joe joe a few years back from swat think he got to 55 56 in that green neon

I have been testing everything!

I think next to birch with resin the plastic laminated ac plywood is next best

can't say fish isn't working to get where he wants to be lol fish you have built more boxes in the last year than i have in the last 3 well i take that back the last year lol in three years i have had every different design in my trunk except for subs up port back an port an sub up.

Lol! I have hade 7 totaly diffrent setups and each one modified a few times before. I moved on to a difrent design! I have 3 boxes in the 55'!s one a bit more than the others!

chris that looks like just birch huh?

i just am sick of predrill and BS issues with MDF lol ive been using birch in the civic..

Yea! The thing I like most is the birch holds up to mounting and re mounting. The plastic laminated ac ply is great aswell!

birch is the best to work with

yeah no predrill or splitting.. and so much more easy to lift the boxes in and out of the cars lol

We have been useing Ultralite mdf....its a mdf and burch mix.....expensive tho.

anybody tried the spax mdf screws? you supposedly dont have to predrill or anything just drive it in!! no countersinking either and wont split supposedly!! i bought a box and am planning on trying them on my new box but didnt know if anybody had tried they yet?

hadn't tried those screws yet cody but i may look for some. i have use mdf all my 5 yrs of building an never had nothin but a soaking of sweat an weight issues, the real weight issues didn't kick in till i got the alpha's them plus box is heavy as hell.

I've wanted to do boxes out of 100%, well 99% steel for sometime now, but no equipment or most of all, not enough money for that.

ohh yes, and timmay got over a 60 with particle board in a crx, not even using the typical crx box.

Well Alan its like this on the plywood question...




In the late 80's that is all we used was plywood we didn't know any different but we did multy layer it to make it stronger it always worked very well thats how box building started was with plywood then partical board the mdf i remember when i used to laugh when a customer ask for mdf then i built my first box with it and heard what bass what supposed to sound like.....

And another example is look up the SPL portion of the scoresheets from finals say 94 LOL and look at the numbers now ANY QUESTIONS????? Dont use plywood it will be a waste of your time unless you just wanna prove you can make it work than go for it your knowledge back then woulda been helpful so you can do well with it but it will take you three times as long to build cause of the layers you would need to do.....

Hope that helps

X2 That's what my box is made with..

ill let ya'll know how the spax screws work out im cutting the peices for the box today and should be putting it all together today or tomorrow depending how good the kids are but ill let everybody know im also using 3/4 in mdf!! didnt have the money for birch they wanted like 55 bucks a sheet!!

spax has a screw that you dont have to predrill mdf ? hmm, seems to good to be true. have to hunt them down. i think im just going to hunt down more the AC exterior ply. its like birch but a little cheaper. i did one out of it yesterday. seems like good stuff . cuts build time waaay down. and no hassile with predrill bits breaking and needing two drills etc. major pain when im building alone..im building a whole van from it for finals too

yeah i found them on the web and they are specifically for mdf they got them at menards its like 6 bucks for 200 screws!! i usually have to build all my stuff by myself since nobody around here seems to wanna help except my girl im teachin her!!lol

How well did they do ? Seems pricey, but worth it from haveing to predrill.

I've used trupan before, is that what you mean?

so i just put my battery box together with the spax screws and work pretty good not the easiest to get started but def alot quicker then predrilling and only split i seen was where i had 2 screws cross each other! oops but even when the were within a inch of the edge wood did not split and sunk real nice but def make sure you have the right size bit i had 1 size down of phillips and it was stripping them but as soon as i switched to the right bit didnt happen again!! ill take some pics of the box when done!!

wood glue, and cabnet wafers are strong

no wonder your trunk box didn't work ummmmm

wood glue and cabinet wafers have been kicking everyones asses for year in the loudest crx's in usaci beleive that player

i can think back about 4-5 years now that it has been doing this to be exact

lol aight

thats all eckers box's are put togather with, and it would be hard to go against what he has done to people in the lanes for years

yea it would be but i just would love to see him show up on a saturday an run instead of running on sunday to get a place, but no hate cause ya gotta be good to do some Dung Pile like he does it. but what i kno i only been to one finals an from what i have been told this been going for some years now.
