    Wood hack here. I'm attempting a horn build using wood. First I need to try and complete this circle and fabricate a mount for the compression driver. If successful I'll keep going, focusing more on dimensions. DSC_0004.JPG DSC_0005.JPG Woods not cheap. Didn't draw blood today using power tools. All is good. Got to stay busy says, my wife.

    Nice progress.

    Are you working from a set of plans?

    Going for the gusto; a tapered piece with angle cuts:eek:. I’d definitely be nubbing it by now.;) Cant wait to see the final product!

    No plans to speak of on this attempt. If I can complete the circle the next build will be dimensionally correct. We like our tandem, the third one. Been riding, forever.

    Is there actually a market out there for these? I think I could probably whip up a few pairs after a bit of dabbling. Shipping would be an issue, but it would be a fun 2018 project. Any plans online one should go off of?

    I could be interested in a pair to try on top of my Onk's. I'd be curious about their freq response range and drivers etc... but they just look so badass. I am still in love with the way all of OMA's stuff LOOKS. Who knows how it sounds.

    It’s not at the front of my to do list but I will be making a set of horns from either cherry or mahogany 2” lumber I have sitting in the garage. I’ll gladly post them here or elsewhere. I may consider making them for others if they work out OK. The main thing I will need is correct measurements for surface mounting any and all drivers.

    H DSC_0006.JPG eck, anyone can build a bucket. Try building a conical cone. I'm also using a Birdseye router bit. Easier said than done. Getting both sides taper the same is not easy. If you're off a degree your out of luck. My first attempt did not come out as planned. Next time I'll use tape and lots of it before I use Glue. Good thing I get my wood cheap.

    You've misunderstood, Amigo. The only differences between the structures we have made are the amount of taper in the individual pieces, and the fact I installed ends on mine. Your first picture appears to show bevelling both edges, not the dado method you show in the last pic.

    Just for anyone else attempting this in the future, getting the taper should be one of the easier steps with this method. Rip all the staves to the same width first, then cut all to length, then set up a jig and cut the tapers on all pieces with the same setup at the saw. Switch to the dado blade and carefully set the bevel angle. This is the only time consuming step. Glue-up using this method is easier with all the pieces at once, rather than doing in parts as the initial pics appear.

    I made all cuts at the tablesaw in about an hour, including time to change from the rip blade to the dado stack.

    Both sides are tapered and just flipping the board won't result in the same taper on the other side. I think building a bucket is much different than a conical horn.

    All my pieces started out equal in dimension weather right or wrong. You can see in my first pic how there started to be a slow downward slope on the small end. Why haven't got a clue? While gluing these up I paid attention to the big end knowing well it wasn't going to work out when I was halfway done.

    I sure as heck ain't no carpenter nor am I a mathematician. But I can use Grammarly.

    Yes, you can do this, Amigo. But there is a trick to it. Ya gotta tape the offcut back into place on the side it just got cut from, in the same orientation it came off. Now you'll have parallel sides again ,and can flip and run through the jig again to cut the other side. My bucket staves are tapered on both sides, and this is how I did it. It just doesn't show well in the photos since the taper is slight; there is only 3/8" in 14" height.

    Thanks and I'll give that a try upon my return. Help appreciated.

    Those wood horns sure have a FLARE to them.
