    I came up with the same blue tape trick a few months ago, but I use it with hot glue to hold boards while routing.
    Holds every securely in the horizontal plane, but peels off easily and cleanly.

    The tape trick is so handy on so many different things, you'll love it. Also works great for sanding small panels that would be hard to hold. The most obvious use would be copying panels using a table router, love using this trick for that.
    Ooooo, that's a BIG curve! I did think it looked thicker than 3/4"

    So the difference between the outer glue/epoxy line and the inner, smaller circle glue line is about 3/4" thickness? That's a neat trick, gives a perspective to the shape the outside will be too.

    I like the tape trick with the superglue. Thanks, I'm using that soon for sure.

    Yep, betting you're right. Seems everyone that has worked with this new Ceramic line of drivers love them.

    Started on the sidewalls but didn't get very far this weekend, hope to finish them up next weekend.

    Using an Industrial Epoxy Laminating Resin. I like this a little more than glue because it soaks into the MDF further.

    Pins are your friends! Makes clamping so much easier when you don't have to fight the panels sliding around all over the place. Two pins in opposite corners usually suffices.

    Clamped up and let it sit overnight. Ready to go the next morning.

    Inside of the left sidewall. Decided to take advantage of an operation available in my CNC software, Spiral cut from center out. By stepping over 1/4" at a time, it left a pretty good scallop. Not sure how much benefit the ridges will have on the back waves but figured it couldn't hurt me. It would have been difficult to apply traditional damping to the sidewalls due to the compound curves.

    Most of the panels for this pair of enclosures will require cuts from both sides. In some cases, there will be fixtures made to accommodate this.

    Rear Baffles:

    Here is a pic after the inside of the rear baffle was cut. Behind the rear baffle, you can see a fixture that will be used to cut the outside of the rear baffle

    Learned this trick from a Luthier youtube video. Masking tape on both panels with a squiggly line of super glue. Acts like double back tape but is much easier to peel off when finished. You would also be amazed at how strong this is.

    An example of how much super glue used. Be careful not to get to close to the edges or it will squeeze out and get on your MDF, not good.

    The Mystiques - Build Thread

    Made a little progress this weekend. Decided on a name for the pair, "The Mystiques". Definition: An aura of mystery that surrounds a person or thing. Seems fitting considering the shape of the enclosures.

    Drivers will be the new Ceramic 6" woofer (SB17CAC35-4) and CQ66 Ribbon Tweeters. Cabinets will be tuned with a 2" Precision port at 37Hz, F3 should be around 39Hz. All panels will be 1" thick and there will be two horizontal braces (above and below the woofer) to assist in putting everything together properly. Knuckle wrap test should result in bruised knuckles. Cabinets will be painted white to match the Ceramic driver and incorporate Carbon Fiber veneer on the front baffle insert.

    Will share any tips or tricks I have up my sleeves as we move along, hope some of them will benefit fellow DIY'ers. The redesigned enclosure will make use of some of the suggestions from fellow TT members and will also incorporate a couple of minor changes to the insides of the enclosure as well. Hope to have the basic cabinets cut and assembled by the end of the month. Thanks for following along.
