    Re: Cabinet / Baffle CNC Service

    I regularly use SolidWorks 2010 3-D modeling software as a part of my day job., and I can model up speaker cabinet panels and assemblies pretty easily in my off hours.

    If I provide you with the SolidWorks files is your CNC machine able to import and cut per those files (assuming cuts are within your machine's specs)? If not do you have a preferred file format?

    Thanks!

    Jim,I'm using 24.5 x 17 for the baffle dimensions. Not sure if that's exactly what you need, but an inch one way or the other won't make much of a difference to the price.

    1.5" MDF (two 3/4" layers) are $62/pair baffles
    1.5" birch ply (two 3/4" layers) are $92/pair baffles

    THat includes the rebates for the drivers.

    Thanks. The shop smelled really good with all the oak chips.

    Thanks for the reply Dave. Pretty much as I suspected WRT the angled machining, but you can always hope! :p

    A lot of the tips/ticks you list would work great...if you aren't trying for a nice stain finish. Bondo + stain = barf, unfortunately :p. Would work great for mdf or the like, though. My table saw's a little small to run these through on...but maybe my miter saw could handle it. Might be a bit wide, though...

    As for the vertical form, I was debating about that. On one hand, I would love to use a form to help glue things up--it would make life a WHOLE lot easier in that respect. But on the other hand, it would still be a huge pain to get the perfectly accurate angle on there, so you could glue up the baffle by itself, then simply trace the desired supports/sides out.

    But otherwise, do they look fairly feasible to you? I wont ask you do do any real work until I order drivers (sometimes I have the attention span of--oh look, a pony!), but you'd be one of the first to know ;).
    I see. Didn't realize you were going for a wood finish. You could use a miter if it's big enough. Most 12" chop saws will do a 7-1/2" to 8" cross cut.

    After a little though I think the best way to do this would be to cut the support braces first with all the angles (the CNC makes this part really easy and accurate). Then fix the baffles between the supports so the backs or sides don't show. As long as the miter cut is reasonably close you're good. You won't see the back or side so if the angles are little wide it won't matter (just caulk it so it's air tight).

    I think the whole thing is totally feasible. It's different than the usual box, but not impossible.

    You also might want to look into one of these . They make referencing the blade to the table a snap.

    HA! I literally laughed out loud at that one. Nice...


    Unfortunately machining beveled edges like that is beyond the capability of my machine. Since the cutter is perpendicular to the piece being cut doing angles like that on and end is essentially not possible. I say essentially because it is possible to use ball end mill and ramp the it up and down and mill the angle, but it would take essentially forever ;)

    If I were building something like that the way I would do it would be to cut all the baffle pieces slightly oversize in the vertical direction. I would then cut a vertical brace to act as a form with the correct angles for the faces. It would also support the assembly from behind. I would then set my table saw as close as I could to the desired angle and put the bevel on the baffle pieces that way.. Any amount if "slop" in the assembly could easily be filled with glue or bondo. Or like my old man told me when we were doing crown molding "do your best and caulk the rest". I'm sure he didn't invent the saying, but it was appropriate...

    You could also try to curve the whole thing out of a single piece over a form, but I think it would screw up the speaker mounting surface.

    That's all beautiful work from a beautiful machine. How is your ability to do waveguides into a thick baffle? A lot of people turn their own on a lathe but milled into a baffle with a woofer opening would be even better.

    If you could do that, I would be interested in your services for a pair of smallish waveguides. (think ZA5.2 size) Let me know if you are able, interested and not already overloaded.

    What kind of data file does your equipment use? I can output 3D geometry in almost any format.
    John,
    I would be very interested in doing something like that. I;ve actually had an idea for a waveguide in the back of my head for a while.

    It's a little more complex in that it requires true 3D movement on the machine. Most of what I've shown here which is really more like 2.5D work. My experience with 3D is somewhat limited, although I have done some personal projects that turned out pretty well. It just takes me longer in the programming stage.

    I use Solid Edge for 3D design work, if you can send a file in the native .par format that would be excellent. Next choice after that would be an IGES format.

    I'm thinking of pursuing some hybrid line arrays, with a waveguide for the tweeter and a mid array above/below. The array would be sectioned into 2 driver segments and curved a la CBT. If I ever get serious I'll shoot you a Sketchup file.
    Thanks. The line arrays were actually pretty fun to make. The front side with the round-overs doesn't look to bad either;)



    I can do hardwoods. I'm cutting a pair of oak baffles this weekend. Fortunately there seems to be pretty good access to rough sawed hardwoods in my area. Maple, oak, hickory, black walnut, cherry, poplar, elm, and beach, are common around here. Ash was common a few years ago, but the emerald ash borer really took out a lot of trees.

    Let me know about the hybrid line arrays. Sounds like a good challenge.

    The tweeters are goldwood GT302'. They're only $2-3/peice. You do need some stinkin' line arrays :D

    By created library I mean a number of existing files for a different designs. Like for the next baffle, you wouldn't program CNC again. Sorry I am not familiar with CNC jargon.
    Any of the prices quoted include the CAD and CAM work necessary for production.

    $360 for the pair as a flat pack. That includes the birch lining and double thick front baffles. Any roundovers, construction, or finishing would be extra.
