MY First Subwoofer Build 15"
« on: May 14, 2018, 10:11:54 AM »
So as the DIY continues, and also because the lasers do thing so quickly, I did some cutting on 18mm supawood,

ideas from this

Very awesome, you don't mess around.   :)

Are you doing sealed subs like that?  ...With a pre..existing design?  And, Faital Pro or B&C, or...?  :)

 :o Damn, that's hardcore.  Like some of the stuff I see on the hardcore bassheads group, car subs.   PS: Something I've sen there, that was new to me, is they sometimes have massive ports, that are adjustable, variable.

That's some laser, what wattage does it take to get through 16mm MDF? The guys I use are only able to do up to 6mm.

those are craft lasers, 0.5-.75kw watt 1000x1000 bed

My machine is a 4KW 4000 x 2000 bed, i can cut 20mm Mild steel, 12mm Alu and 16mm SS 304/316

And also wood, but i could, setting go up to 50mm, but it's setup for steel work, not for wood, as you need a hood for the smoke, just smells like braai when cutting  :giggle:

That is an insane bit of kit.

That machine, plus Autodesk Fusion and the Slicer plugin, the fun you could have...

To what tolerances can you cut alu, and are you cutting commercial?

It's not DIY unless you have burned out your router, torn the foot off your orbital sander, destroyed a few edge trimming bits, covered yourself in dust, stuck something on backwards, drilled a hole in the wrong side & sworn out loud... repeatedly...  :sd: (I did none of those things :whistler:)

Looking good, will 16mm be thick enough though?
