I like dowels between all sides and then bond them together in the center somewhere.

Anotherguy Posted November 13, 2009 Report Share Posted November 13, 2009 2x4's, lots of glue and deck screws. Quote Link to comment Share on other sites More sharing options...
Basshead08 Posted November 13, 2009 Report Share Posted November 13, 2009 Only reason I don't use 2x4's is because of the airspace they take up Quote System tear out has begun...Out with the old i have a iq of 128 i graduated at the top of my class tell me how im reatrded you are the 1 thats dumb as hell you can't even spell Look at the underlined text hahahahahahahaha I think of it as the virgin losing the virginity technique not just jumping in to it, and pounding away, but going at it slowly over time, to get to that full extreme Link to comment Share on other sites More sharing options...
fritosaregood Posted November 14, 2009 Author Report Share Posted November 14, 2009 (edited) For some background on this. Im a mechanical engineering student at college. and year i had a statics and dynamics class followed by a mechanics of materials class. It basically taught be about how things are stress by forces and what works to stop stresses. One thing that was focus on are like and I beam the long skinny part of the I add a rigidness and also spaces the two top and bottom parts to a distance. that also add strength. The there are T beams which is just an I beam without a bottom. So i built a box a few months ago and used the t beam concept to brace my box. pic of the box i also added some dowel rods because the T beam concept would of had a disturbance on the air flow So this semester in class we have a program called Solidworks that we can build 3D models in and now we are learning how to make the program do stress analysis. So i decided to see how good the Tbeam concept worked. How i did it was a flat peice 30 by 17 inches, with all edged fixes in space like it would be attached to a box, Then put a force on the entire piece. I did 4 separate test each with the same force. the pics are just screenshots put in paint and saved. first i did just a .75" thickness to base things off of Then one of just doubling the thickness how some ppl do The pictures look the same, but the max stress on the double thickness is 1/4 that of the single thickness. Then i did a single 1 " dowel rod The max in this was actually double that of doubling the thinkness Then i did the Tbeam way. This way looks to be alot better, but the numbers actually show that around the edges (green spots) its a little more than the double thick board, the across the face is much better Edited November 14, 2009 by fritosaregood Quote seller feedback: http://www.stevemeadedesigns.com/board/ind...showtopic=61719 http://www.stevemeadedesigns.com/board/ind...showtopic=68281 build log: http://www.stevemeadedesigns.com/board/index.php?showtopic=44800 Gf's build: http://www.stevemeadedesigns.com/board/topic/54346-kickergirls-camaro-new-box-pg-5/#entry753970 Link to comment Share on other sites More sharing options...
Sanitarium Posted November 14, 2009 Report Share Posted November 14, 2009 that's how i'm gonna be bracing my next build. left over 1/2" mdf (rest of box will be 3/4" except the front ring. Quote Link to comment Share on other sites More sharing options...
Marlo Stanfield Posted November 14, 2009 Report Share Posted November 14, 2009 Depending on the size of the enclosure it will either be dowels or all thread. Then of course 45s, glass, and a ton of resin. Quote 1998 Ford Explorer Eddie Bauer... New setup, old ride... QX56 is staying stock til I get loud...
