THIS THREAD CHANGES FROM YUCHI A290 HORN TO AN 18SOUND XT1464. FOLLOW Moded 2226H + 2451J on XT1464
Hello again guys. I had a great project going in the fullrange section, a B&W teardrop shape with Fostex 168 drivers. As life has it, something came inbetween. After a long time, wanted to go back to the project and finaly finish it.... When I pulled the enclosures out of a dry storage, they have been badly cracked. That was the second time when translam didnt work (wesayso had same problem). And in the bin they went, sadly.
Now.....new project
Currently Im having a CAD program done for the famous Yuichi A290 horn, so that it can be machined on a CNC router. Found a guy in my country *central Europe) who would be willing to make them. You can find them on ebay and such, but still over 1.000 dollars for a pair. I wanna push the price way way lower. Once I got the CAD file, I will bargain with the CNC company to have them made. As a compensation for good price, I would like to know if anyone else would be interested in a pair. I do not promise this, but I think we could get it down to 600 per pair...depends on the amount of horns he will make. Danny

puppet - I dont want to make money of it. I am paying for the CAD files, and routing job. More then happy to share with fellow DIYers...If it works out, I can be the middle man to have the horns made for others, no charge for me, except if I have to pick them up (gass money), or have to ship them (which is normal). I just want to "spread the love" so to say
Only the original drawings are copyright. Any redo of the drawings is copyright of the artist (or who he assigns them to).
Having something that a CNC can use would be very useful. If the CNC has enuff z you shoud be able to do at as an upper & lower half, plus the vanes.
I ask because as soon as i get the new dongle for my CAD software i was going to takle this exact drawing. But no sense in doing it twice. I already have a 1st order approximation of the horn drawn.
When i get my CAD straightened out i’ll look at neskor’s drawing.

No, he wont make you a free pair or dozen....why do you have to write that? You know what I mean. Im not here to make money, Im writing this to convince the manufacturer to make more of them, for a fair price, like a group buy. I get a pair for a good price, and somebody else, who wants a pair, also.....Jesus And anyway, your from US, why would you wont a pair? Shipping would kill you. Are you trolling me?
So I was able to create a 3D exported file from Sketchup, easily opened in 3D Print program in Windows. Looks bloody good if I say so my self now off to the manufacture with it (he requested specific file type for his CNC router) which I was able to do with this easy to use 3d program.
Ill let you know, if he accepts the file. What Im afraid of is the polygons instead of a perfect circle, might mean there will be some sanding involved.
Also I went for a horn with straight and curved sides, dont know which one is it, but the first part is straight, and close to the throat its curved, same as TAD TH4001. The curve in horizontal (sides) is within 5% of the original plan, curve in the vertical (top and botom pieces) is within 6%, my best guesstimate. I dont think Yuichis measurement with hand on a finished TH4001 were that precise, some margin for error sure must be included.
Anyway, hopefully the manufacturer will be able to make me a mockup from foam first. Then comes the wood model.

First STL 3D model
Little teaser....
Hope it displays correctly
