Nice!
Those are perfectly symmetrical curves. Nice attention to detail.
newB on 05/25/2007 02:44:26
WHY THANK YOU!!!!!!!!!!!!!
very proud of those i'll incorperate them into a future box design and keep you all posted
my goal is to build an elaborate "Flared" box
a DCTT box
and MAYBE a TL box if i can get a blueprint of one
then roll up to my local shop, blow their mind and ask for a part time building job.
;D
wish me luck

blue print of a TL.. i can give you one.. but depends what kind of driver are you willing to use....
that is a very nice job you have done on bending the MDF... in technical terms those are know as half cuts.. and they work very well for making architecture models out of MDF and other softer materials...
tho it is an easy thing to do technically.. its requires a lot of skill and patience to do it practically...
i would just be concerned about one thing and that is the structural integrity and strength of such a structure.. if you can re-inforce this and probably layer this curve with fibreglass coat then it becomes a very strong and leak proof structure...
with such skill levels you can definitely do a lot lot with building enclosures..
let me know if i can help u on this front in any ways...
looking at ur skill level i want to just pin a small idea into ur mind..
a perfect enclosure for any driver is a perfect sphere... it ideally nullifies the effect of the bouncing back waves that emerge from a speaker , the so called standing waves... they have an unwanted effect on the moving cone..
the structure and symmetry of a sphere is such that if create a practically inert environment for the driver enclosed and produces an ideally perfect transient response from the driver...
see if you can work something out with MDF .. it shall be an asset and somethign to be proud of as a driver enclosure designer / manufacturer....

Nice job newB!!! When I first read the title of this post, I would have said Not generally, but yes or maybe. (If you know how and have lots of patience. But it's a lot of work doing all the relief cuts as you did.
Expert carpenters will often use hardwoods and steam press wood into the curves and shapes desired. (Boat & furiture building tricks)
I would agree with Victor about using some kind of laminate or glass work to reinforce the curves.
Again, very impressive work here bud! CLAP

PS You have a real talent for working with wood. If you really like this sort of work, consider taking a job as a furniture and cabinate maker. If you go this route, take plenty of pictures of your best work and WOW the shop owner into hiring you. You may need to start as an apprentice for a time. But as your skills expand, the income will grow too. It's a humble job that takes lots of patience and skill. But a journeyman level carpenter can make some serious $$$ in time.

i will need some design help. one for the TL box which will have an Ascendant Audio Assasin 10, but that will be in a month or two.
what i would love now is the #s for a box 35x15x15
im thinking a single slot vent in the middle, and doing 6inch curves on each side going into it. a couple extra inches in port length would probably be best to compinsate. then the two 12s on the outside.
is that enough to stand out to a shop if its built like a tank?
i have the plans for the DCTT box that will blow them away im sure.
plus with graduation money.....

Nice Job on the curves. I just built a ported enclosure for my CDT 12 and bent the MDF for a 3.5" flair using the releif cuts.
Good Job

Ill see if i can take some pics tonight when I get home from work. Its not exactly what I would call "pic material" since i was rushing and didnt get everything perfect like i normally do. Its just a quick box I threw together to see how the SQ 12 would sound ported. Its 2^ft net (after displacements) and is tuned to 36hz.
I'll take some pics tonight,
Just some FYI for ya to make flared ports.
10 cuts at 3/8" apart create a 3" Flair.
10 cuts at 1/2" apart create a 3.5" Flair
10cuts at 3/4" apart create a 4" flair and so on
To reinforce the port I used gorrilla glue in between each cut and then lacked it into place using CA Glue (industrial strength Super Glue). I then went back over it with some fiberglass resin then screwed everything in nice and tight.

i am in awe here....you have given me a reason to rebuild.....if i could just talk my cousin into building something out of this "curved thing of beauty"....there will be a new project....
newB on 05/27/2007 03:58:44
nice! keep us updated!!!!
i'll post pix of my future install with all the bent angles.
;D

Hvve a question... how deep do the curf cuts need to be in order to get a good bend w/o breaking or fracturing? (3/4 - 1.0 " MDF)
Swez
Ash on 05/27/2007 12:14:43
Beautiful work! That kind of work takes a lot of patience which you seem to posess... Keep up the good work.
newB on 05/27/2007 14:59:05
they need to be as deep as possible.
the thinner the remaining layer the easier it bends and more careful you need to be.
leave likea 32nd of an inch left.
;D
thats why fiberglass resin will be my best friend on the full install
