After great success with the Gjallarhorn's and Othorn I built, going to try another one. Can see that build thread here: http://www.avsforum.com/t/1465617/triple-gjallarhorn-othorn-build

Here is what I got done yesterday:

3D Model:




Cutting:



AppleMark

Assembly:





Will get the rest of the panels done tomorrow and start gluing it up.

Hey now, I cut two Ghorn's and an Othorn all by hand. I'll call this more intelligent.

Very nice. What other projects have you done using the CNC?

Didn't have much time today. Got everything up to one side panel glued one. Just need to glue the other side on and get the driver mounted to be done.

Overall fairly easy to put together. Have a few modifications to make it easier. Would like it to be simple enough that anyone could do it with just a drill / glue.

Thinking to Duratex this guy too. Came out quite well on my other subs. Has anyone had experience carpeting subs? Thoughts on doing that?

Good news is with that setup you won't need to build another sub ever again.

Yea they are great! Haven't watched much with them. Watched Sunshine and two light fixtures fell from the ceiling.

I didn't put lock washers on when I put the drivers in. Did you? Wondering if they need to be tightened after a bit.

I did not, but I used 1/4"-20 threaded inserts, and cranked them down pretty tight. I doubt they'll come loose.

ds1,

I know of a local shop with a cad rig that could build this for me. Would you mind sharing your cad file?

I certainly can give you my files. Unfortunately it's generally not as easy as that. Even if I gave you all my DXF's they are probably still going to need to do a lot of work to get everything exact due to differences in setups. The machine is one thing. The other big thing is material thicknesses. My baltic birch was slightly less then 18mm / 12mm, I modeled based on that. If your material is .72 instead of .707 it won't fit in the slots etc.

If you're seriously interested in some Othorn's we can discuss some flat packs.

Interesting...Looks like you were working from version 1 and added parts of version 2. Version 2 was all about beefing up the bracing with a minor modification to the throat. I could have given you cad files for all of this but as you say they really only work for the particular CNC or builder you are using so they still require modification. It may not have helped much...


Have fun.

Flat packs would be awesome! I have a brand new pro5100 that needs a home. What do you think the cost would be?

Have fun.

Did I miss anything? It seems really rigid even compared to the Ghorn's. The dado's help the panel stiffness and the brace that goes from the bottom hatch panel up to the driver cutout panel makes it super solid.

What was the change to the throat?

The main thing I need to look into is the cost of shipping. How many would you be interested in? Two? Doing multiples is easier for me and obviously shipping wouldn't be much more for two.

I see you also have Ghorns. My plan was to have one Ghorn and one Othorn. Are you able to do a flat pack for the Ghorn? If so, I would be interested in one of each.

No reason I couldn't. The main concern would just be shipping the Ghorn. It's actually much larger / heavier. Ends up using 5 sheets of material vs the Othorn's 3.

I'll PM you with some more thoughts.

Did you get those dang driver panel braces in? Those weird ones at the 45 degree angles.

Put braces underneath and thinking to skip those. I really don't see how it could add that much rigidity that close to the edge.

At worst you could always add them later if needed.

Really looking forward to your listening impressions! What are you going to power it with?
