Gotz1lung Posted May 19, 2009 Report Share Posted May 19, 2009 (edited) Ok, So after much thought and debate, i just cant see walling my truck with only 4 woofers, so i have a basic retangle box at 20x62x20 in mind and i really want to try a Kerf'd box for this build. My questions: How do i figure the port area when both ends Flare out?the port needs to be 18.5x8x10 to get my 37hz tuning, but if im figuring this the way i think its done, the acual port length that isnt kerfed would only be 3.25inches long How do i measure for the kerfs to Get different radius'? I need to make a 90* within 3-4ins, is that way to tight of a bend for the MDF? Sorry for so many questions, if this was sheet metal i d have no problems...hahahaha Ill redraw the box to clean up all my "oops" lines and scan it in for you guys to see what im talking about. its subs forward/port up BTW.

BanginOnABudget Posted May 19, 2009 Report Share Posted May 19, 2009 (edited) where the fuck are you gonna fit a box that wide? here, if you cant read what it says, just ask. it says: my rule: 1/2 the width of the port. port is 10" wide and the kerf is 5" wide. Edited May 19, 2009 by BanginOnABudget Quote im taking out my passenger seat, battery is disconnected, going to unwire and take out the three amps, take out the 70+ lb box, then the platform so i can crimp 1 wire.

I just did a box the port was 8 inches wide so i made my kerfs with a 4 inch radius. for port area. the area you look at is the area thats isnt kerfed 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...
Gotz1lung Posted May 19, 2009 Author Report Share Posted May 19, 2009 (edited) My Sierra is 62 3/8 from cab panel to cab panel with the seat brackets removed. Its damn near 80 threw the pocket to the sheetmetal.. So from your example its gonna add 10in to the total length and 10in to each side of the port as far as area??? Thanks for the sketch BTW!

korey_hofer Posted May 19, 2009 Report Share Posted May 19, 2009 here is what I read when I started designing this is off of ROE a 90 degree flair involves 10 cuts with a standard 1/8" width blade. http://i121.photobucket.com/albums/o239/hu...eighths3inh.jpg moved fence on my saw 1/2 at a time, gives a 3.5" flair http://i121.photobucket.com/albums/o239/hu...ndahalfinch.jpg moved fence on my saw 3/4 at a time, gives a 4" flair http://i121.photobucket.com/albums/o239/hu...uarter4inch.jpg moved fence 1/2 inch at a time, made 20 cuts all together. 6" radius http://i121.photobucket.com/albums/o239/hu...6inchradius.jpg Quote previously known as wenn_du_weinst aka fucking internet coward supreme.

Gotz1lung Posted May 19, 2009 Author Report Share Posted May 19, 2009 http://www.soundsolutionsaudio.com/forum/i...showtopic=23110heres a link to a thread i made on *** about bending mdf Nice tutorial... I would have never thought of doing the Mutiple strip at the correct width of each cut. here is what I read when I started designing this is off of ROEa 90 degree flair involves 10 cuts with a standard 1/8" width blade. http://i121.photobucket.com/albums/o239/hu...eighths3inh.jpg moved fence on my saw 1/2 at a time, gives a 3.5" flair http://i121.photobucket.com/albums/o239/hu...ndahalfinch.jpg moved fence on my saw 3/4 at a time, gives a 4" flair http://i121.photobucket.com/albums/o239/hu...uarter4inch.jpg moved fence 1/2 inch at a time, made 20 cuts all together. 6" radius http://i121.photobucket.com/albums/o239/hu...6inchradius.jpg Nice close ups.. Thank you It looks as if I might be able to pull this off.. Does drilling holes in the cuts help that much more for strength. Ill prolly use resin instead of glue to fill with. It makes sense, air out resin in, and each one of those holes adds to the bondable face area...

I think all that drilling holes does is help draw in the resin. I just made a box with a kerf port i tried to drill holes for the resin but it got to be a hassle. i had to hold the wood bent to drill the holes too. i also backed the kerf with a layer of fiberglass heres a link to the build i just did http://www.stevemeadedesigns.com/board/ind...mp;#entry629336 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...
