u cannot press MDF in a curve

I don't think he meant that it's getting pressed into a curve, rather the MDF is molded into a curve.

Afterall, MDF is nothing but sawdust and glue that is cast/molded into it's shape. There's no reason why it couldn't be made into other shapes besides a flat panel.

I'm also working on 8's. It's going to take a while.

Yes you can and I've seen it done with my own eyes. There is a guy in San Diego that can do it...he's the only one that I know who can. He charges an arm and a leg.

I dont think its possible.. it takes hundreds of tons of pressure just to press a 3/4" sheet of MDF... im calling BS for the 3rd time....

i have seen it done, they get it wet with something (chemical mix) till its flexible, then shape it to whatever.... just like drywall

MDF, or medium density fibreboard, is a common replacement for wood. It is usually manufactured as flat sheets, and is a stiff, rigid, inflexible material that is difficult to bend into the sort of complex shapes often required. It has now been found that by impregnating MDF with ammonia (used in anhydrous - that is to say, dry gaseous - form) the MDF can be made relatively plastic, and in its plasticised state can quite easily be pressed or bent into almost any shape required.

You "don't think" it can be done. Every single one of your BS call has been debunked. You really need to learn a few things before you start ranting. It's getting old.

(WO/1993/019910) BENDING AND SHAPING MDF

Thanks for the link. That is one method, there is also another method. People with these skills are making a whole lot of money.

...and I'm calling you out for being a troll.

The easiest way to "bend" MDF is to dado the board about every inch or so(depending on how curvy you want it to be) to make them more flexible, fill the gaps with resin then fiberglass it once you have it bent and set in place. You're gonna need some muscle, a nailgun and patience to do this. I've seen this exact method used by a member on Termpro and it looked really good and was solid as a rock. A few layers of fiberglass on the non-dadoed side wouldn't hurt ether.

its called kerfing, get off this thread already.

The technique has a name? Cool.

Nice boxes btw.

Surprised you are still even here Tuan. I would have had less patience than you....

Tuan, send me an enclosure!

I'll use a single Hifonics XX-2412 (12") off an Orion 2500D @ .5ohm and give you all the feedback you'd like, as I have tons of access to a TL.

And, of course, pay for the shipping, and however more you see fit.
